The first video cards of the Ampere family, the GeForce RTX 3080, went on sale this week, along with their reviews. Next week, September 24, sales of the flagship GeForce RTX 3090 will start, and then the results of its testing should appear. But the Chinese resource TecLab decided not to wait for the deadlines indicated by NVIDIA, and presented a review of the GeForce RTX 3090 right now.
To begin with, we recall that the GeForce RTX 3090 video card is built on the Ampere GA102 GPU, in a version with 10496 CUDA cores. It is the most advanced Ampere GPU in the consumer segment to date. In the reference version, the chip has a base frequency of 1395 MHz, and the Boost frequency is declared at 1695 MHz. The graphics card is equipped with 24 GB of GDDR6X memory with an effective frequency of 19.5 GHz. Coupled with a 384-bit bus, this gives a bandwidth of 936 GB / s.
The system on which the GeForce RTX 3090 was tested was built on the flagship 10-core Core i9-10900K processor with a frequency of 5 GHz. It was complemented by 32 GB of G.Skill DDR4-4133 MHz RAM. Tests were carried out in 4K resolution with synthetic and gaming loads. In games with ray tracing and AI anti-aliasing support, DLSS tests were performed with or without the indicated options.
In synthetics, the difference between the GeForce RTX 3080 and the flagship GeForce RTX 3090 was 7.1 and 10.5% in the 3DMark Time Spy Extreme and 3DMark Port Royal tests, respectively. Not the most impressive results, considering that the recommended prices for video cards are $ 699 and $ 1499, respectively.
A similar alignment of forces is obtained in games. Without ray tracing support, for example, in Far Cry, Assassins Creed Oddysey and others, the difference in frame rates between GeForce RTX 3080 and GeForce RTX 3090 ranged from 4.7 to 10.5%. In games that support ray tracing and DLSS, the maximum gap was 11.5%. Such a result was recorded in Death Stranding, and ironically, with tracing and DLSS disabled.
It turns out that the average advantage of the GeForce RTX 3090 is 10%, despite the fact that this video card is more than twice as expensive as the GeForce RTX 3080. But here it is worth noting that NVIDIA itself positions the GeForce RTX 3090 as the successor to the Titan RTX, that is, a semi-professional solution. Perhaps, in some work tasks, the potential of this card will be revealed much better.
