Patrick Schur has tweeted the purported specs for AMD’s flagship Radeon RX 6000 Series graphics card, which has been commonly referred to as the Radeon RX 6900 XT. According to the software engineer, the Navi 21 XT models will supposedly boast a 2.4 GHz game frequency (clock), 16 GB of GDDR6 memory, and a 255 W TGP.

That’s a very impressive gain in the game clock department, if true. AMD’s Radeon RX 5700 XT 50th Anniversary GPU only has a 1,830 MHz game frequency, while the standard Radeon RX 5700 XT’s game frequency is limited to 1,755 MHz. A 645 to 570 MHz improvement? Sure, we’ll take it.

The Radeon RX 6000 Series flagship will also feature 16 GB of GDDR6 VRAM, which has been confirmed by previous leaks. While that memory configuration places it above NVIDIA’s GeForce RTX 3080 (10 GB), green team is expected to counter with a 20 GB variant.

As for TGP, 255 W suggests a substantial bump over the previous generation’s 225/235 W total board power, but that remains considerably lower than the GeForce RTX 3080 and GeForce RTX 3090’s 300+ W power demands.

Schur pointed out that this is an AIB model, which means that the specifications for AMD’s reference card could be different.

There have also been rumors of a supercharged Radeon RX 6000 Series “XTX” model that AMD is prepping to counter to NVIDIA’s GeForce RTX 3090. We’re guessing that this will be something akin to the Radeon RX 5700 XT 50th Anniversary edition, which was sold in limited quantities. At the very least, it should give red team’s marketing department something extra to work with.
