The Radeon RX 6000 , also known as Big Navi or Navi 21, will be presented by AMD on October 28. During the Radeon RX 5000 presentation session earlier this month, AMD gave a preview of this new card.
Some information about its configuration has leaked
The complete configurations of the Radeon RX 6000 based on the RDNA2 architecture will be revealed by AMD on October 28. Some details on the configuration of the latter have nevertheless reached us. The rumors that spoke of Big Navi operating on a frequency above 2 GHz are apparently well founded. Indeed, according to Videocardz the Navi 21 XT range will have a working frequency of 2.4 GHz . The base cards will run at 2.3 GHz and the Navi 21 XL series will have a clock speed of 2.2 GHz.
According to some leaked information, there is apparently a big gap between the base frequencies, the gaming frequencies and the boost frequencies. For the XT series, the base frequency would be around 1.5 GHz. It will go up to 2.1 GHz in gaming mode and reach a peak of 2.4 GHz in boost mode. For the XL series, the base frequency is around 1.4 GHz, then 1.9 GHz in gaming mode and will reach 2.2 GHz in boost clock. There are therefore significant jumps between the base frequencies, the game clocks and the boost frequencies, i.e. more or less 500 MHz between the base frequencies and the game frequencies then 300 MHz between the game clocks and the boost frequencies.
The performance of the Big Navi
Configuration-wise, the Radeon XT series would have 16 GB of GDDR6 memory with a 256-bit bus . The nominal TDP power would be around 250 Watts. Seen on October 8, the Big Navi has 3 fans and is powered via an 8-pin PCIe.
The powers of big Navi are close to the performance of Nvidia's RTX GeForce 3000. AMD CEO Lisa Su promised that these new cards allow you to have a 60 FPS image with 4K definition . According to tests carried out by AMD, the frame rate reaches 88 FPS on Call Of Duty Modern Warfare and 73 FPS on Gears Of War 5 in UHD. It should be noted that these tests were carried out with RayTracing not activated.
What is surprising in the story is above all the enormous differences between the base frequencies, gaming frequencies and the boost frequencies. We do not know if it is AMD which is spreading its rumors to create the effect of surprise and confuse its competitors. But in any case, we will be fixed on the real frequencies of these Big Navi within a week.
