AMD Radeon RX 6000 Series Specs Leak: RX 6900 XT, RX 6800 XT, RX 6700 Series
AMD's Radeon RX 6000 series graphics cards, based on the RDNA2 graphics architecture, will see the introduction of the company's first DirectX 12 Ultimate graphics cards (featuring features such as real-time raytracing). A VideoCardz report sheds light on the specifications. The 7 nm "Navi 21" and "Navi 22" chips will power the top-end of the lineup. The flagship part is the Radeon RX 6900 XT, followed by the RX 6800 XT and RX 6800; which are all based on the "Navi 21." These are followed by the RX 6700 XT and RX 6700, which are based on the "Navi 22" silicon.
The "Navi 21" silicon physically features 80 RDNA2 compute units, working out to 5,120 stream processors. The RX 6900 XT maxes the chip out, enabling all 80 CUs, and is internally referred to as the "Navi 21 XTX." Besides these, the RX 6900 XT features 16 GB of GDDR6 memory across a 256-bit wide memory interface, and engine clocks boosting beyond 2.30 GHz. The next SKU in AMD's product stack is the RX 6800 XT (Navi 21 XT), featuring 72 out of 80 CUs, working out to 4,608 stream processors, the same 16 GB 256-bit GDDR6 memory configuration as the flagship, while its engine clocks go up to 2.25 GHz.
A notch below the RX 6800 XT is the RX 6800 (Navi 21 XL), which cuts down the "Navi 21" further, giving it 64 compute units or 4,096 stream processors; the very same 16 GB of 256-bit GDDR6 memory interface, and up to 2.15 GHz engine clocks. The RX 6900 XT, along with the RX 6800 series, will be announced in the October 28 presser.
The next chip AMD is designing is the 7 nm "Navi 22" silicon, which features 40 compute units. On paper, this count looks similar to that of the "Navi 10," and it remains to be seen if this is a re-badge or a new silicon based on RDNA2. The RX 6700 XT maxes this chip out, featuring 40 CUs or 2,560 stream processors; while the RX 6700 features fewer CUs (possibly 36). The interesting thing about these two is their memory configuration—12 GB of 192-bit GDDR6.

It happens to all of us, lol. I still don't understand how the 6900 XT can keep up with the 3090 with such a memory disadvantage. I get that the 128MB cache is helping, but... how?
The 128MB cache must be waaaayyyyy faster, to make up for the overall lower bandwidth to main VRAM.
But then it only has 10GB VRAM.
And do you want to talk about availability of cards that aren't available EVEN FOR PRE-ORDER (at announced price)?
2080Ti MSRP was $999, ya know. On paper.Cool part is that this cache bit is from Zen 3 development.
AMD's GPU-CPU synergy starts to pay off.
They jumped from being behind on using bandwidth effectively to trouncing NV.
Gap between 3090 and 3080 is 10%, how does one fit glorious 3080Ti into it.
Ampere is DOA, non-redeemable. Only FUD to save face:
