AMD RDNA2 (Big Navi) Reveal. RX 6900 XT, 6800 XT and 6800 inbound.

AMD revealed their highly anticipated RDNA2 line of GPUs today.  You can watch the full reveal on the link below.

AMD will be launching the 6800 XT and 6800 on November 18.  

The 6800 XT is the competitor to NVidia's RTX 3080 and it looks to be quite close, at least in rasterization workloads, and priced at $649.  I suspect this card won't be as fast as the RTX 3080 when ray-tracing is turned on, but you do save $50 and get a lower TBP and more VRAM.

The 6800 is priced in at $579.  Interestingly, this is quite a bit higher than the RTX 3070, so it seems AMD is fairly confident that this GPU is faster across the board than the NVidia card.  It also means that $579 is the lowest cost RDNA2 GPU with this initial launch.

The 6900 XT was also listed as the full-fat RDNA2 GPU.  Available December 8th, it is being marketed as a RTX 3090 competitor at $999.  Some caveats here.  In the slide comparing RX 6900 XT and RTX 3090 fps, AMD notes that "Rage Mode" among other things were enabled.   Meaning the 6900 XT had to be overclocked to achieve those results.  This may be the version to get for liquid cooling enthusiasts though, as the chips are likely a higher bin to hit the same clockspeeds at the same board power as the 6800 XT with 8 more CUs enabled.

All in all, this is looking like nearly a 100% performance uplift from the previous AMD king, the Radeon VII.

What's the story on SR-IOV support in Big Navi, is AMD reserving this for the datacenter? As a threadripper user it'd be awesome to be able to startup a VM to play a few quick rounds of <insert name of Windows-only title> on my linux box with pci-passthrough.
