AMD announced its first RDNA 2 (Radeon RX 6000 series) gaming GPUs during a live stream (24m42s) on October 28.
AMD originally planned for RDNA 2 to have 50% more performance per Watt than GPUs using the RDNA 1 microarchitecture. Now, AMD is claiming 54% more performance per Watt for the RX 6800 XT and RX 6800, and 65% more performance per Watt for the RX 6900 XT. Part of the efficiency gain is due to the use of "Infinity Cache", similar to the L3 cache found in Ryzen CPUs. This allowed AMD to use a 256-bit memory bus with 2.17x the effective memory bandwidth of a 384-bit bus, while using slightly less power.
The RX 6900 XT ($1000) has performance comparable to Nvidia's RTX 3090, with a total board power (TBP) of 300 Watts. The RX 6800 XT ($650) is comparable to Nvidia's RTX 3080, also with a 300 Watt TBP. The RX 6800 ($580) is around 18% faster than Nvidia's RTX 2080 Ti, with a 250 Watt TBP. All three of the GPUs have 16 GB of GDDR6 VRAM and 128 MB of "Infinity Cache".
The 6800 XT and 6800 will be available starting on November 18, while the 6900 XT will be available on December 8.

and now you lose. backed into a corner, instead of addressing the actual points, you have nothing.
btw, I don't believe you for a second from the way you talk that you build or sell anything. you're a customer, and someone from a VAR showed you a configurator once, then you read some pdfs. you say you quote out UCS. that's a great test, since google won't give you the answer. to build a UCS config and quote it out, what is the url of the cisco site?
nice try, linux admin at midsize commercial account.
