In particular, problems arose again with the Electron-VM oxygen production system, which was mounted in the Zvezda module. Last week, this complex already experienced a failure, and it took several days for the Russian crew of the station to restore its operability.

In addition, it is reported that there was a malfunction of the toilet in the Zvezda module: the astronauts reported on the indication “Poor quality preservative.” Plus, the smoke of the vacuum cleaner was recorded.

However, the Russian cosmonauts were able to quickly cope with all the problems. For example, the oxygen generation system has already been re-restored – the failure is associated with the docking of cables in another part of the Zvezda module. The toilet has also been resumed – this problem is explained by the presence of an air bubble in the system.

Still, it should be noted that failures in the Zvezda module are recorded quite often. Moreover, it is here that there is a crack, due to which air leaks on the ISS. Recently, the gap was repaired with a temporary patch.

Review of the smartphone Xiaomi POCO X3 NFC: expansion of expansion / Smartphones

Review of the smartphone Xiaomi POCO X3 NFC: expansion of expansion / Smartphones


⇣ Contents

Xiaomi has again started a game that only the company itself can understand. Together with the lineup of “big” Xiaomi and “budget” Redmi, a third is now being formed – under the revived name POCO. The very word “Pokophone” is still a thing of the past, but why a new sub-brand is needed in the company’s already very rich assortment is not entirely clear. But it is there, and it is expanding.

Xiaomi POCO X3 NFC is a mid-range smartphone, which, perhaps, has only a name in common with the summer POCO F2 Pro. I don’t see any special idea behind POCO – these are quite typical Xiaomi smartphones that cost less than they might if you look at their characteristics. The same as Redmi, but with a large POCO lettering on the back. Specifically, the X3 NFC model sees a direct answer to realme 6 Pro, which for almost half a year was the main choice in the category “about 20 thousand rubles”: a huge (6.67 inches) screen with an increased refresh rate is also installed here (and higher than that of realme , – 120 Hz), there is a mini-jack, NFC-module (the presence of which is directly in the model name). And, of course, a more powerful hardware platform: Qualcomm Snapdragon 732G versus Snapdragon 720G – you need to beat a competitor with something.

Xiaomi POCO X3 NFC – information about the filling according to the CPU-Z application

⇡ #Design, ergonomics and software

There is not even an external continuity between the two POCOs released this year – which is understandable, because F2 Pro came out on the domestic market as Redmi K30 Pro. Here we are dealing with a “real” POCO, which is confirmed by a hefty logo on the back. At the same time, there is not a single Xiaomi inscription on the case – the manufacturer is promoting the sub-brand, without reference to the parent company.

In addition to the large logo – by the way, an interesting design solution that we see more and more often (for example, on Honor 30 Pro +) – the back cover is also characterized by a non-uniform painting with a shaded center, in which a block with cameras and flash is inscribed. It is larger here than in Redmi Note 9S / 9 Pro, and is visually reduced to a circle. There are no associations with the younger models – and this is no less important than the high recognition of the device itself.

Moreover, the design of the back is preserved regardless of the color of the smartphone, of which there are two – blue (“cobalt blue”) and dark gray (“gray dusk”).

The bezel is absolutely standard, but it is extremely difficult to stand out here. The front camera is inscribed in a hole in the center of the upper part of the screen, the earpiece grille is very narrow and is located under the very top edge. The frames around the screen are not large, but noticeable – the display occupies 84.5% of the front surface area, which, of course, is far from a record.

The screen is covered with hardened Gorilla Glass 5, but the back panel is already lined with mirrored plastic. It looks, of course, indistinguishable from glass, but the difference is obvious to the touch. The edges, judging by the lack of characteristic veins, are also made of plastic. The body of the smartphone has received splash protection (class IP53).

It is very difficult to talk about the convenience of using a gadget with a 6.67-inch screen – for this, many factors must converge, such as a thin body and an almost complete absence of frames around the screen. There is no such thing here – from the “care of the user” we can only note the curved edges at the back. POCO X3 NFC is even thicker than its main competitor, realme 6 Pro – 9.4 mm versus 8.9. And heavier – 215 grams versus 202. This is a large two-handed smartphone, the size of which has to be tolerated in order to take advantage of the large screen.

It does not add to the joy that this is a very slippery gadget – as I already wrote, the plastic here is “disguised” as glass, it is glossy. And let your fingers have something to cling to, unlike devices made of real glass, it is still a much better solution to hide the X3 NFC in the complete case. It is made of transparent silicone and adds a few extra millimeters to the smartphone. Get ready for the fact that it will not fit into every pocket.

At the same time, I am glad that at least they did not remove the “extra” ports on a large smartphone – we can find a mini-jack on the lower edge, and on the upper one you can see an IrDA. Xiaomi does not abandon the idea of ​​interacting with household appliances using the classic standard.

The fingerprint scanner is located on the right edge. Yes, I understand everything, putting a scanner on the back panel is already flagrantly unfashionable, and under the screen for this price category, it may be a little expensive, but you can still do unfashionable things. The capacitive sensor is not bad – it works quickly and quite clearly, but the coverage area of ​​the scanner is not enough, which is why the percentage of non-response is quite high. At the same time, you touch the scanner in your pocket every now and then, which is why the smartphone regularly asks to enter the PIN-code, because “there are too many unsuccessful unlocking attempts”. This is not the worst side scanner I’ve seen in recent years: for the flagship Sony Xperia 1 II, for example, the situation is even worse. But the decision itself is still controversial. True, it does not become less common from this. You can, however, rely on the face recognition system for which the front camera is used. At least I couldn’t deceive her with a photograph. And, by the way, she recognizes the face in the pandemic mask, unlike the iPhone with its depth sensor. The method is not the most reliable, but at least it works quickly and without failures.

POCO X3 NFC received the Android 10 operating system, but now running MIUI 12 – the special Poco Launcher is still in place, but it has very few differences from the standard shell of Xiaomi smartphones. Previously, there was a special application screen with normal search, grouping of applications by type and various settings. Now this function has been transferred to the standard MIUI (starting with the twelfth version), so the differences between POCO Launcher should be looked for under a magnifying glass. It is worth saying only about the absence of several announced innovations of MIUI 12 – for example, there are no cool animated “Super Wallpapers” here, the animations of the operating system are not particularly different from what we have seen before, and the notification panel and control panel are not separated.

But I will note the successful inclusion of a vibration motor in the process, which, for example, emphasizes the moments when you scrolled to the end of the list in the settings. There is a Windows-style wallpaper carousel – the pictures are updated every time, and you can look on the Internet for information related to them. The icons on the screen are the same, but some are specific to POCO: among them there is a gap in the form of a camera icon, extremely similar to the icon that is almost inevitable for a smartphone on Android Chrome – it is easy to confuse them. But the fonts have been updated, there is a function for transferring photos without exchanging metadata, and the camera application itself is new, from MIUI 12 … It seems that POCO Launcher does not keep pace with all MIUI updates, and they will be added to it gradually and pointwise to save for smartphones POCO identity. Why this is needed – I do not quite understand. At the same time, the shell works fast and smoothly. Advertising in basic applications is a payment for the opportunity to buy a cheap phone with such characteristics, and it hasn’t gone anywhere either.

⇡ #Display and sound

The main characteristic of the Xiaomi POCO X3 NFC screen, which the company emphasizes in positioning the smartphone as a gaming gadget, is the ability to work with an increased refresh rate, 120 Hz. And this is really the feature that distinguishes the smartphone from the general background – before that, for such money, only realme 6 Pro provided such an opportunity, but with a lower frequency (90 Hz). And I must admit, the increased frequency is not a marketing gimmick that will merge with the landscape in a few years, it really affects the experience of interacting with a smartphone. In basic scenarios, these are smoother swiping animations, after which the 60 Hz mode (which we can return to at any time to save energy) already seems jerky. This is especially evident in games – I think there is nothing to explain here. Just note that today most of the popular mobile games are friends with an increased refresh rate. The touch surface of the screen has a frequency of 240 Hz, which also has a positive effect on the gaming experience.

Otherwise, this is a quite usual screen for its class: LCD with IPS-matrix, 6.67-inch diagonal, Full HD + resolution (2400 × 1080 pixels). The pixel density is low, but sufficient for the picture to be perceived normally – 395 ppi. The viewing angles are wide and there is an effective oleophobic coating.

Measured brightness limit without software boost during auto-tuning is 459 cd / m22 – the result is average. The contrast is also not the highest – 1126: 1.You can use your smartphone on a sunny day, but without much comfort. You shouldn’t expect deep blacks from its screen either.

The image settings are quite extensive: it offers a dedicated reading mode with a warm screen tone, font adjustments, dark mode, even special options for working with VR. Color reproduction is also available: there is an automatic adjustment depending on the lighting, and a saturated mode, and a standard mode, and the ability to manually adjust the color tone to taste. I measured the color rendering of the display in automatic mode (according to visual sensations it is extremely close to “saturated”) and in standard mode.

In both modes, the color gamut is close to the sRGB standard – it does not work with the extended color gamut. But in automatic (as well as in saturated) coverage is still slightly wider than this standard. The gamma is quite typical (2.26), the scatter of the curves is observed mainly in light shades, but insignificant. The color temperature is greatly increased – it lies in the range from 7,500 to 9,500 K with a median of around 8,500 K. The average deviation of DeltaE according to the Color Checker scale, which includes both a wide range of colors and shades of gray, is 6.53 at a norm of 3.00. The colors are bright and cold, but far from normal.

При активации стандартного режима цветовое пространство уже полностью соответствует стандарту sRGB. Гамма примерно та же, но кривые ведут себя более стабильно. Цветовая температура приближается к эталону — 6 500-7 000 К. И само главное, среднее отклонение DeltaE по шкале Color Checker составляет уже 2,75, попадая в результате в границы нормы. Смотреть кино или фотографии лучше всего в этом режиме, играть можно и в автоматическом/насыщенном. Как бы то ни было, экран настроен очень хорошо, оставляя как выбор для любителей более ярких и насыщенных цветов, так и для поклонников естественности.

В Xiaomi POCO X3 NFC есть мини-джек, но звуковой тракт обычный — ожидать какого-то особенно крутого звука не стоит. Аналоговый разъем несет только удобство — можно подключить или свои старые-добрые проводные наушники, или беспроводные, когда у них кончился заряд, без переходника. С беспроводной передачей данных порядок — поддерживаются и aptX, и LDAC, и передача Hi-Res Audio. Есть и приятный сюрприз — здесь стереофонические динамики, в паре с расположенным на нижней грани работает фронтальный. Вместе они звучат очень даже ничего.

⇡#«Железо» и производительность

Xiaomi POCO X3 NFC – не просто первый смартфон с новой платформой Qualcomm Snapdragon 732G, они чуть ли не одновременно представлены. Конечно, говорить о том, что Qualcomm подготовила новый процессор специального для Xiaomi, нельзя, но это совершенно точно временный эксклюзив. Тоже своего рода ответ realme 6 Pro, который оказался первым в мире смартфоном со Snapdragon 720G – позже на нем построили Redmi Note 9S/9 Pro.

Это «геймерская» платформа среднего уровня, в которой основную нагрузку берут на себя свежие ядра Kryo 470 Prime с частотой 2,3 ГГц и Kryo 470 Performance с частотой 2,2 ГГц. К этим двум ядрам присоединены шесть энергоэффективных  Kryo 470 Efficiency частотой 1,8 ГГц. Ядра Prime и Performance основаны на архитектуре Cortex-A76, в то время как остальные шесть ядер разработаны на основе Cortex-A55. Процессор изготовлен по нормам 8-нм техпроцесса Samsung. За графику отвечает тот же GPU Andreno 618, что и в прошлогодней Snapdragon 730G, но его частота повышена. Кроме того, Snapdragon 732G поддерживает некоторые функции Snapdragon Elite Gaming вроде Qualcomm Game Jank Reducer, графический драйвер Vulkan 1.1 и True HDR.

В сочетании с фирменным игровым режимом, который позволяет аппаратной платформе не распыляться на выполнение сторонних задач, это могло бы дать Xiaomi POCO X3 NFC преимущество на фоне конкурентов и звание главного игрового смартфона в своей ценовой категории… Могло бы, но не дает — POCO X3 NFC действительно показывает неплохой уровень производительности, с некоторым преимуществом перед конкурентам в 3D-приложениях, но серьезным отрывом тут не пахнет. Заявленных 300 тысяч баллов в AnTuTu у меня добиться от этого смартфона не вышло. Проблем с большинством игр у вас не будет, но кадровой частоты на близком к флагманам уровне вы не добьетесь.

Однако преимущество перед realme 6 Pro у POCO X3 NFC в играх все-таки будет — этот смартфон почти не подвержен троттлингу, в отличие от творения realme, у которого небольшие проблемы мы все-таки зафиксировали. В тесте CPU Throttling Test у POCO X3 NFC частота падала до 95 % от максимума при средней производительности 148 GIPS. Авторы смартфона хвастают особой системой охлаждения LiquidCool 1.0 Plus с тепловой трубкой — и делают этог не зря. Она весьма эффективна, что заметно даже тактильно — смартфон почти не нагревается, в частности, и при выполнении самых сложных задач.

Добавлю здесь, что в играх также помогает качественный вибромотор — он действительно дает мощную отдачу. Может быть, это и не DualShock, но для смартфона прилично.

POCO X3 NFC предлагается в двух версиях: с 64 или 128 Гбайт флеша стандарта UFS 2.1. Оперативной памяти — всегда 6 Гбайт (LPDDR4x). Последнее, кстати, тоже чуть смущает — для современного «игрового» гаджета не то чтобы маловато, но, честно говоря, впритык. Расширить объем основной памяти можно при помощи карточки microSD – для этого придется пожертвовать одной из SIM-карт, слот гибридный.

⇡#Связь и беспроводные коммуникации

Xiaomi POCO X3 NFC работает с сетями 4G – за это отвечает входящий в состав Snapdragon 732G модем Snapdragon X15. Скорость, с которой он может работать с данными, не сообщается. Зато все необходимые для России диапазоны поддерживаются.

С беспроводными модулями полный порядок: Wi-Fi 802.11a/b/g/n/ac, Bluetooth 5.1, NFC (с Google Pay), ИК-порт, навигационный модуль с GPS, A-GPS, ГЛОНАСС, BeiDou.

⇡#Камера

Разница в цене между POCO X3 NFC и POCO F2 Pro – почти двухкратная (старшие версии стоят сегодня 22 тысяч и 42 тысяч, соответственно). Но интересно, что по части главного мерила качества современного смартфоне — камеры — они очень похожи.

В POCO X3 NFC установлено четыре камеры. Главная идентична той, что использовалась в POCO F2 Pro, – это 64-мегапиксельный Quad Bayer-сенсор габаритами 1/1,7″ (отдельный пиксель — 0,8 мкм), который предлагает по умолчанию съемку в разрешении 16 мегапикселей с возможностью принудительно перейти на сверхвысокое разрешение. Объектив лишен оптической стабилизации, но обладает довольно высокой светосилой — f/1,9. С главной камерой работает фазовая система автофокуса. Широкоугольная камера даже чуть улучшена: те же 13 Мп (и размер пикселя — 1,12 мкм), зато объектив при том же угле охвата (123 градуса) предлагает повышенную светосилу (f/2,2 против f/2,4). Автофокуса в нем как не было, так и нет.

Оптического зума не предусмотрено ни в F2 Pro, ни в X3 NFC – двукратное масштабирование производится за счет кропа с 64-мегапиксельной картинки. При съемке с хорошим освещением потери в качестве не слишком заметны, а в сумерках и ночью качество уже страдает — сильно падает детализация, видны огромные потери в тенях. В сложных по освещению условиях уверенно себя чувствует только главный модуль со стандартным фокусным расстоянием (26 мм). Ему тоже ощутимо недостает оптического стабилизатора, но заметно помогает ночной режим с многокадровой экспозицией. Широкоугольный модуль позволяет рассчитывать на хорошую картинку днем (радует и цветопередача, и динамический диапазон, и устойчивость оптики к солнечным бликам) или в сумерках (небольшой выигрыш в светосиле относительно «старшего брата» чувствуется), но ночью уже сдает позиции. Отсутствие автофокуса не позволяет рассчитывать на этот модуль вне пейзажных сюжетов.

Слева – 16-мегапиксельный снимок, справа – снимок с разрешением в 64 мегапикселя

Переключиться на съемку с задействованием каждого субпикселя можно в «профессиональном» (ручном) режиме съемки либо выбрать из общего списка опциональных режимов на отдельном экране. Примеры — выше.

Упомянутый выше ночной режим работает со стандартным углом обзора и с двукратным гибридным зумом — с широкоугольным режимом уже нет. Но рассчитывать на чудотворное влияние объединения кадров с дальнейшим «докручиванием» при помощи нейросетей не стоит. По-настоящему темные сцены POCO X3 NFC вытянуть не в состоянии — яркость в освещенных участках поднимается, контурная резкость тоже, но небо, например, уже выглядит кашей из пикселей. С применением зума ситуация усугубляется проблемами со смазом — получить по-настоящему резкую картинку затруднительно. По ночной съемке POCO X3 NFC (как и POCO F2 Pro, кстати) выступает на уровне актуальных Redmi Note и, пожалуй, уступает realme 6 Pro.

Но чем-то же должен POCO X3 NFC отличаться в плане камеры от смартфона почти в два раза дороже. Это «чем-то» — макро-камера. Вместо оригинального 5-мегапиксельного модуля с эквивалентным фокусным расстоянием в 50 мм тут стандартный широкоугольный 2-мегапиксельный модуль без автофокуса. Макро совершенно обычное — подобный уровень демонстрирует сегодня большинство смартфонов среднего сегмента, от Nokia 5.3 до vivo Y30. Разрешение низкое (1600 × 1200), и чтобы добиться резкости, нужно аккуратно подбирать расстояние от объекта — и как-то варьировать этот момент нельзя.

Четвертая камера в POCO X3 NFC, конечно же, отвечает за искусственное размытие заднего плана — это рядовой датчик глубины, который базируется на двухмегапиксельном сенсоре. Справляется с этим смартфон неплохо, но в портретном режиме отсутствует возможность зуммирования, отчего рассчитывать всерьез можно только на ростовые и поясные планы. На крупных планах уже «плывет» геометрия. Фирменные фильтры позволяют играть со светом и  «выносить» портрет на однотонный фон — в этом случае обрезается изображение очень грубо.

Приложение камеры в MIUI 12 обновлено. Общая логика осталась более-менее неизменной, но, с одной стороны, добавилось удобное меню с возможностью быстро поменять формат кадра, включить таймер и изменить некоторые настройки, с другой — набор этих настроек неочевидный (почему именно здесь макросъемка, а другие режимы — в разделе «Еще»?). А главная моя претензия ко всем смартфонам Xiaomi – активированный по умолчанию водяной знак с названием смартфона — оставлена на месте. Есть опция стереть водяной знак при просмотре в галерее, но она не работает для кадров с широким углом обзора и снимков в ночном режиме, например. Добавлю про возможность редактировать «карусель» режимов — в нее, например, по умолчанию не входит ночная съемка, но это легко исправить. Возможность выставить «кинматографические» рамки в кадре и доверить смартфону самостоятельно монтировать видео в режиме VLOG на месте — из нового (или не замеченного в прошлые разы) скажу о режиме съемки сразу и на фронтальную, и на тыльную камеры, доступном почему-то только для видео.

Есть и режим помощи нейросетей («искусственного интеллекта») при съемке для определения сюжета и подгонки кадра соответствующим образом — подключаются к процессу они достаточно умеренно, но местами могут перебрать с насыщенностью. По умолчанию эта функция отключена — но, думаю, можно смело ее активировать, не боясь испортить кадр.

Xiaomi POCO X3 NFC предлагает стандартную функциональность в отношении видеосъемки — 4K с частотой до 30 кадров и умеренной стабилизацей, также доступна «усиленная» стабилизация в Full HD 30p. Имеется бьютификатор для видео, кинематографические рамки (формат сужается до 21:9), следящий автофокус (среднего уровня), набор фильтров. Пока перечислял это, понял, как же вырос средний уровень современных смартфонов и в этом отношении тоже. POCO X3 NFC смотрится в плане видеосъемки очень достойно — в джентльменском наборе не хватает разве что съемки с искусственным боке и возможности менять фокусное расстояние (именно переключением между камерами, а не цифровым зумом) прямо в процессе съемки, не выбирая заранее.

Фронтальная камера та же, что и в POCO F2 Pro, даром что не выдвижная — 20 мегапикселей, f/2,2, фиксированный фокус, без вспышки. Она вполне хороша — фокус выставлен корректно, пространственные искажения при съемке автопортретов не слишком значительные, есть программное боке, бьютификатор, фирменные фильтры. Неплохие селфи можно получить и при неярком искусственном свете.

⇡#Автономная работа

Xiaomi POCO X3 NFC получил аккумулятор емкостью 19,61 Вт·ч (5160 мА·ч, 3,8 В). Это позволяет скомпенсировать ущерб для автономности со стороны огромного ЖК-экрана — смартфон уверенно держит заряд сутки при стандартном формате использования (соцсети, звонки, умеренное время в играх). Если играть «в полной выкладке» (на максимальной яркости, с 120-герцевым режимом), батареи должно хватить на 6-7 часов, что тоже, в принципе, неплохо.

В нашем традиционном тесте с воспроизведением Full HD-видео на максимальной яркости, с включенными обновлениями и уведомлениями, POCO X3 NFC продержался почти 11 часов — результат для аппарата с ЖК-экраном достойный. Проблем с автономностью у смартфона нет.

Для зарядки используется порт USB Type-C, поддерживается система быстрой зарядки с комплектным адаптером мощностью 33 Вт. Полностью смартфон заряжается примерно за час десять минут. Беспроводная зарядка не поддерживается.

⇡#Заключение

Несмотря на мутную ситуацию с суббрендами и позиционированием своих смартфонов, Xiaomi продолжает массированную атаку на оставленные Huawei по независящим от нее обстоятельствам позиции, наращивая свое присутствие в среднем ценовом сегменте. POCO X3 NFC приносит с собой сразу несколько флагманских штучек, которыми до этого из «двадцатитысячников» мог похвастаться только realme 6 Pro – тут и экран с повышенной частотой обновления, и очень быстрая зарядка (33 Вт), и мощная система охлаждения. Для серьезного отрыва от конкурентов смартфону чуть-чуть не хватает производительности — Snapdragon 732G не дает ощутимого прироста относительно стандартной для этого сегмента Snapdragon 720G. Но суммы качеств (большой и быстрый экран, сенсорная панель на 240 Гц, автономность) для звания лучшего бюджетного смартфона для геймеров хватает вполне.

Добавляем к этому не выдающуюся, но неплохую камеру (как тыльную, так и фронтальную) и получаем более чем адекватный ответ на удачный аппарат realme. Не сказал бы, что Xiaomi POCO X3 NFC однозначно превосходит его (там и тыльная камера чуть получше, и двойная фронталка, и слот карты памяти выделенный), но да, это очередной потенциальный хит от народной компании.

Advantages:

  • мощная (в сравнении с конкурентами) аппаратная платформа;
  • крупный и хорошо настроенный дисплей;
  • хорошая автономность и очень быстрая зарядка;
  • стереодинамики;
  • неплохая (но не более того) тыльная и хорошая фронтальная камера;
  • мини-джек, ИК-порт.

Disadvantages:

  • слот для карты памяти совмещен со слотом для второй симки;
  • камера посредственно себя проявляет в темноте;
  • смартфон реально огромный.

China banned games, social networks and online services that cause addiction in children

China is imposing strict measures to keep children away from addictive digital content. We are talking about updating existing laws that now prohibit “addictive” Internet products and services for children. Under the new rules, video game providers, streaming services and social media platforms must set time and consumption limits for underage users.

The changes also oblige service providers to take “necessary measures” to prevent cyberbullying. Various means can be used to do this, including deleting and blocking content at the request of the parents or guardians of the affected children. The updated law will come into force on June 1, 2021.

To some extent, the amendments are a formalization of what the Chinese authorities have done before. The fact is that in the past in the Middle Kingdom, attempts have already been made to study and control the ethics of gambling addiction. The tightening of legislation, according to the Chinese authorities, will help protect the mental and physical health of children, as well as relieve the formation of addiction to video games or some other online services.

However, an outright ban on addictive content can force web platforms and game developers to comply with certain security measures, even in cases where the likelihood of developing an addiction is extremely low. While the new rules will primarily affect content targeted at the Celestial Empire, they may have an impact on Chinese-made digital products and games that are published in other countries.

very expensive, hard to see, and also dead pixels

very expensive, hard to see, and also dead pixels


Xiaomi last summer unveiled its first transparent TV, the Mi TV Lux OLED Transparent Edition, for an impressive $ 7,200. The novelty is now sold only in China, but this did not prevent the well-known blogger Linus Sebastian from the Linus Tech Tips channel from acquiring this curiosity, and of course observing it.

To begin with, let’s just remind you that TV Lux OLED Transparent Edition is equipped with a 55-inch transparent OLED screen with a thickness of 5.7 mm manufactured by LG. The panel has a 120Hz refresh rate, 10-bit color depth, 93% coverage of DCI-P3 color space, 1ms response time and 150,000: 1 static contrast ratio. The TV has an Always On Display function, thanks to which the necessary information can be displayed on the screen even when the device is turned off.

Externally, the Xiaomi TV looks extraordinary – although transparent displays cannot be called a novelty, they are extremely rare in the “wild”. In fact, the panel is not completely transparent, but rather tinted with a brown tint. It is created by tiny LEDs and conductive paths leading to them. They can be seen if the panel is viewed from a minimum distance.

But what looks very curious on the outside is not always practical. And just the practicality of transparent screens for home use raised serious questions even at the stage of the first prototypes of such displays. Linus also pays attention to this: in dark scenes or areas of the image, you see what is located behind the screen. That is, to fully utilize this premium and innovative TV, an additional black background or curtain is required. But then what’s the point in being transparent? The question seems to be rhetorical.

Having a black background provides a much more contracted image

Having a black background behind the TV provides a much sharper picture

The blogger also noted that due to the fact that the pixels are made as small as possible so that the panel is transparent, the pixel grid is quite clearly visible on the screen. Again, not the most pleasant feature. Well, another huge drawback is that the TV that Linus got had three dead pixels at once. Not quite what you’d expect for over $ 7,000.

In addition, the blogger was never able to start the TV in 120 Hz mode. But in this case, we can only advise you to read the instructions carefully, since this mode works only when the MEMC function is activated, which Linus just turned off. Another plus point is that the TV supports English, but by default it works in Chinese.

Ryzen 5 5600X confidently outscores Core i5-10600K in SiSoftware benchmarks

Источник изображения: AMD


We previously reported that AMD’s flagship Zen 3 based Ryzen 9 5950X processor showed a very decent performance boost over the previous generation Zen 2 based Ryzen 9 3950X flagship in the SiSoftware Sandra synthetic benchmark. Now it’s time to compare the performance of the younger model of the new Ryzen 5 5600X series with its direct competitor, the Intel Core i5-10600K in the same test.

Recall that the Ryzen 5 5600X has six Zen 3 cores with twelve virtual threads, has 32 MB of L3 cache on board and operates in the frequency range from 3.7 to 4.6 GHz. In turn, the Intel Core i5-10600K is also equipped with six cores and 12 threads, has 12 MB of L3 cache and operates with a frequency range from 4.1 to 4.8 GHz.

As you can see, the maximum frequency of the latter in the automatic overclocking mode is higher than that of the AMD processor. In addition, the Intel chip has a higher thermal design power (TDP) of 125W. For Ryzen 5 5600X, in turn, the declared TDP level of 65 W. In theory, the Intel Core i5-10600K should be faster than the competitor due to the wider TDP range. However, the Ryzen 5 5600X outperforms it in all tests of the SiSoftware Sandra benchmark, at least due to the larger amount of cache memory.

In arithmetic tasks, according to SiSoftware, the AMD chip scored 255.22 GOPS, and in multimedia tasks it showed a result of 904.38 Mpix / s. For the Intel Core i5-10600K processor, the results in the same tests were 224.07 GOPS and 662.33 Mpix / s. Thus, the superiority of the Ryzen 5 5600X over the Intel chip in the first test is 13.9%, and in the second – 36.5%, respectively. For comparison, the Ryzen 5 3600X based on the Zen 2 architecture scores 214.89 GOPS in SiSoftware arithmetic tasks, and 625.51 Mpix / s in multimedia tasks. It turns out that the new Ryzen 5 5600X is faster than its predecessor by 18.8% and 44.6% in the respective tests.

Of course, it would be premature to draw conclusions based on one SiSoftware Sandra benchmark, but the test makes it possible to understand at least an approximate level of performance of the new AMD chip. As a reminder, the Ryzen 5000 series of processors will go on sale on November 5. The Ryzen 5 5600X has a MSRP of $ 299.

Apple launches MTV-style video streaming service that plays music 24/7

9to5google.com


Today, the California tech giant launched a 24/7 stream of music content called Apple Music TV, similar to what MTV offered before it re-specialized into reality television. It is known that in the USA the stream is available for free.

9to5google.com

According to Apple, the streaming service will broadcast exclusive new music videos, concerts, and charts. It premiered today with the broadcast of the 100 most-watched U.S. songs in Apple Music history. A video stream is scheduled for Thursday on the upcoming release of Bruce Springsteen’s new album, “Lettet to You”. In the US, the new music streaming channel should appear in the Overview tab of the Apple Music and Apple TV apps. So far, nothing is known about the launch of the service in other regions.

9to5google.com

The concept of a 24/7 music channel was first proposed by MTV in 1981 after early testing started back in 1977. However, after a while, the channel abandoned its exclusive focus on music and began broadcasting other content, which, according to management, should have attracted the attention of its main audience of adolescents and young people.

China will make its Silicon Valley more attractive to foreigners in response to US sanctions

Источник изображения: Bloomberg


For forty years, there has been a special economic zone in the Chinese city of Shenzhen. This made it possible to turn this part of China into some kind of Silicon Valley: for example, the headquarters of Huawei Technologies and Tencent Holdings are located here. To help China more successfully resist US sanctions, Shenzhen will receive even more autonomy.

The Chinese authorities, as noted by Bloomberg, have recently published a list of reforms and changes that will add autonomy to Shenzhen and increase its attractiveness for foreign investors. First, their intellectual property rights will be better protected. Secondly, the ban on the work of telecommunications companies with foreign capital in the PRC will be lifted. Third, specifically to attract talent from all over the world to Shenzhen, visa concessions will be made.

The city will be able to issue debt securities on the international market, a futures index will appear on the local exchange in Shenzhen. Young companies will be able to place their shares on this site through the system of depositary receipts. Chinese state-owned companies will be given more freedom to carry out market reforms. Finally, Shenzhen will be included in a single cluster with Hong Kong and Macau, which will allow, among other things, the introduction of medicines that are available only in the last two regions of China. In a pandemic, this is an important moment that empowers Shenzhen residents to receive modern medical care.

almost two dozen Switch exclusives made it to the top 40, but FIFA 21 is still in the first place

almost two dozen Switch exclusives made it to the top 40, but FIFA 21 is still in the first place


The Games Industry portal has shared information on the sales of retail editions of games in the UK from 11 to 17 October. Despite the familiar leader, there have been many changes in the ranking.

FIFA 21 held the top spot on the chart despite a 65 percent drop in sales. At the start, the Electronic Arts football simulator lost more than 42% to the previous release, but only in retail – in digital format, the new game is doing much better.

With the exception of FIFA 21, nothing remained of last week’s top three: both Star Wars: Squadrons and Crash Bandicoot 4: It’s About Time dropped from second and third to eighth and ninth, respectively.

Between FIFA 21 and Star Wars: Squadrons, there are five games for the Nintendo Switch at once: the popularity of projects for the Nintendo hybrid console has grown amid the annual Amazon Prime Day promotions.

In total, 18 Nintendo Switch exclusives are listed in the top 40 of the weekly rankings, starting with Animal Crossing: New Horizons in second place, Mario Kart 8 Deluxe in third, Switch-version of Minecraft in fourth, and Ring Fit Adventure in fifth.

Benefits from sales include: Just Dance 2020 (# 7 and 233% sales growth), Jumanji: The Video Game (# 14 and 464%), F1 2020 (# 15 and 220%) and Fallout 76 (16th place and over 1000%).

The only new release of the week to debut on the charts is Power Rangers: Battle for the Grid (# 38). Mario Kart Live: Home Circuit was not included in the rating at all – despite being available in retail, the game itself is downloaded via Nintendo eShop.

The top 10 UK retail charts from October 11-17 are as follows (last week’s result is shown in parentheses):

  1. FIFA 21 (1);
  2. Animal Crossing: New Horizons (4);
  3. Mario Kart 8 Deluxe (6);
  4. Minecraft (7);
  5. Ring Fit Adventure (10);
  6. Super Mario 3D All-Stars (5);
  7. Just Dance 2020 (17);
  8. Star Wars: Squadrons (2);
  9. Crash Bandicoot 4: It’s About Time (3);
  10. Grand Theft Auto V (11).
