There has been some excited chat on Twitter this weekend as more than one source tipped that AMD Radeon RX 6000 series graphics cards would boost as fast as 2.4GHz. The ball started rolling with a Tweet from software engineer Patrick Schur listing purported specs of an AIB partner Navi 21 XT graphics card. Then on Sunday the more familiar leakster called RoGame shared what they claimed to be the GPU clock speeds of the Navi21 XT and Navi21 XL.
Above you can see the Tweet from software engineer Patrick Schur. You can see he asserts the Navi 21XT GPU based graphics cards will feature a 'Game Clock' of 2.4GHz. Other key specs are its 12GB of GDDR6 VRAM and 255W TGP. Later on in other Tweets and replies, Schur clarified that the 2.4GHz was the game clock of an AIB partner card, and AIBs are testing cards with up to 290W TGP, the 255W figure was for reference.
Moving on RoGame added their weight to the above with the following update:
Navi 21 XL
- Base clock 1350MHz to 1400MHz
- Game clock 1800MHz to 1900MHz
- Boost clock 2100MHz (maybe 2200MHz)
Navi 21 XT
- Base clock 1450MHz to 1500MHz
- Game clock 2000MHz to 2100MHz
- Boost clock 2200MHz to 2400MHz
The 'Big Navi' that everyone has been waiting for is thought to be represented above as the Navi 21 XT. This may well have been the unnamed RX 6000 Series GPU that AMD teased recently as a GeForce RTX 3080 challenger with a trio of 4K gaming benchmarks in modern AAA games.
If rumours are correct, AMD is keeping something in reserve. Some sources say that AMD has a Navi 21 XTX GPU with more CUs enabled but there are no credible leaks or material indications about this. When/if the XTX comes it may be an AMD exclusive or special edition, at least to start with. A lower end Navi 21 XE is expected to make a showing too.
Please take the above rumours with a pinch of salt. If it is too salty for you at least you don't have that long to wait until the official RNDA 2 special event hosted by AMD - it will be live streamed next week, on Wednesday, 28th October.
