AMD introduced mobile processors Ryzen 5000


As expected, AMD today announced a new family of Ryzen 5000 mobile processors as part of its presentation at CES 2021. It includes 10 Zen 3 processors codenamed Cezanne, as well as three models with Zen 2 architecture, known by the codename Lucienne (Renoir Refresh).

The Ryzen 5000 processors introduced today come in two classes. The first class is H-processors, which are based on the new Zen 3 architecture, have up to 8 processing cores and are equipped with a Vega graphics core. The thermal package of such processors is set at 35 or 45 W and they are primarily aimed at gaming notebook models with discrete graphics. Second class energy efficient U-processors that rely on Zen 3 and Zen 2 architectures (depending on model) usually have fewer cores and lower operating frequencies, and are also enclosed in a 15-watt thermal package.

The Ryzen 5000 H-series lineup is as follows:

Model # Of cores / threads Max / Base Frequency (GHz) L3 cache (MB) TDP (W) Architecture
AMD Ryzen 9 5980HX 8C / 16T Up to 4.8 / 3.3 16 45+ Zen 3
AMD Ryzen 9 5980HS 8C / 16T Up to 4.8 / 3.0 16 35 Zen 3
AMD Ryzen 9 5900HX 8C / 16T Up to 4.6 / 3.3 16 45+ Zen 3
AMD Ryzen 9 5900HS 8C / 16T Up to 4.6 / 3.0 16 35 Zen 3
AMD Ryzen 7 5800H 8C / 16T Up to 4.4 / 3.2 16 45 Zen 3
AMD Ryzen 7 5800HS 8C / 16T Up to 4.4 / 2.8 16 35 Zen 3
AMD Ryzen 5 5600H 6C / 12T Up to 4.2 / 3.3 16 45 Zen 3
AMD Ryzen 5 5600HS 6C / 12T Up to 4.2 / 3.0 16 35 Zen 3

The 45+ watt HX processors are designed for high-performance gaming notebooks, while the 35W TDP HS processors deliver the H-Series performance in a thinner and lighter chassis.

All Cezanne mobile processors, like their predecessors, are based on a monolithic 7nm crystal with 16MB L3 cache. The graphics core remains the same, it is the same Vega with eight CUs that was used in the Renoir mobile processors (Ryzen 4000). Thus, the performance gain in this case will be mainly provided by the introduction of the Zen 3 architecture, the doubling of the L3 cache and a rather noticeable increase in the maximum clock frequencies.

In terms of performance, AMD noted that the new flagship Ryzen 9 5980HX processor is capable of boosting single-threaded performance by 23% and multi-threaded 17% over the previous generation Ryzen 48900H, allowing it to be used in both games and content creation.

The lineup of energy efficient Ryzen 5000 U-series processors is as follows:

Model # Of cores / threads Max / Base Frequency (GHz) L3 cache (MB) TDP (W) Architecture
AMD Ryzen 7 5800U 8C / 16T Up to 4.4 / 1.9 16 15 Zen 3
AMD Ryzen 7 5700U 8C / 16T Up to 4.3 /1.8 8 15 Zen 2
AMD Ryzen 5 5600U 6C / 12T Up to 4.2 / 2.3 16 15 Zen 3
AMD Ryzen 5 5500U 6C / 12T Up to 4.0 / 2.1 8 15 Zen 2
AMD Ryzen 3 5300U 4C / 8T Up to 3.8 / 2.6 4 15 Zen 2

A lot of the new U-series models with a 15W thermal package look like a rather strange mixture of Cezanne processors on the Zen 3 architecture and Lucienne (Renoir Refresh) on the Zen 2 architecture, which differ noticeably in characteristics, for example, in the size of the L3 cache. In fact, we are talking only about two really new models – the eight-core Ryzen 7 5800U and the six-core Ryzen 7 5600U, while the rest of the processors these are representatives of the Ryzen 4000 series slightly improved in frequency.

Unsurprisingly, when talking about the advantages of the Ryzen 5000 U-series, AMD is focusing on the Ryzen 7 5800U with the Cezanne design. Compared to the old Ryzen 7 4800U, this CPU is promised a 16 percent improvement in single-threaded performance and a 14 percent increase in multi-threaded performance.

Ryzen 4000-based mobile computers have become very common in the past year. According to Mercury Research, AMD’s share of the notebook processor market reached 20.2% by the end of the third quarter, a historic high for the company. The new Ryzen 5000 processors should strengthen AMD’s position by introducing more progressive architecture and increasing performance and efficiency. However, this year the competition in the laptop market will be more fierce, because Intel also has interesting proposals. Quad-core 35-watt Tiger Lake for gaming laptops were unveiled yesterday, and Tiger Lake with eight processing cores should be out by the end of the first quarter.

New notebooks powered by Ryzen 5000 mobile processors will be available from major manufacturers including Asus, HP and Lenovo during the first quarter of 2021. And for all of 2021, AMD expects to launch a wide range of more than 150 consumer and commercial notebooks powered by Ryzen 5000 mobile processors. Also due in the first half of 2021, Ryzen PRO 5000 mobile processors with additional security features targeted at enterprise notebook models.
