A leaked specification of the AMD Navi 21 XT graphics chip (the so-called “Big Navi”) in the Radeon RX 6900 XT accelerator. Unofficially, we can talk about an absolute beast here in terms of clocking.
The leak is the responsibility of software engineer (specializing in reports on AMD) Patrick Schur, which he gave on Twitter AMD GPU parameters. The Navi 21 XT graphics chip used in the Radeon RX 6900 XT is to have 16 GB of VRAM (GDDR6) memory and an extremely high clock frequency of 2.4 GHz (in the “Game Clock” methodology, it is an average value). If Schur’s reports prove to be true, it will be the highest clocked consumer graphics card on the market.
The TGP factor (or Total Graphics Power relating to the power consumption of the graphics chip itself) is 255 W. With 16 GB GDDR6 RAM and the indicated clock speed, the AMD Radeon RX 6900 XT looks like a competitor to the Nvidia GeForce RTX 3080.
We know from previous reports that the cards based on the Navi 21 (RDNA 2) architecture will be available in four different versions. However, we do not know their exact configurations, although the most powerful of them will probably contain 80 CU blocks. AMD will officially reveal the Radeon RX 6000 series on October 28, 2020.
