What an utterly baffling take on this. What does "On paper, the RX 6800 XT should pull ahead from Nvidia." even mean? Do GPUs from different brands have on-paper specification that can be compared to give a realistic performance estimates? No, they don't. TFlops aren't comparable across architectures, VRAM amounts only matter when there's not enough, etc., etc. AMD's marketing said the 6800 XT matched or beat the RTX 3080, which was slightly optimistic, as they are more typically tied. Calling this an unimpressive showing ... how? This is AMD's first competitive high-end GPU in five years. Is it impressive? That's debatable. At the very least it's pretty damn good. Is it "unimpressive"? Not by any sensible measure. Catching up to Nvidia's massive lead in both absolute performance and power efficiency (where AMD is now unequivocally ahead) is very impressive considering where AMD started out from a couple of years back. Most people thought this would never happen.

If Nvidia is postponing the 3080 Ti because of the 6800 series' performance, it's not because they were unimpressive, but because AMD didn't actually deliver a better value proposition or markedly better absolute performance, both of which would have pretty much necessitated a response from Nvidia. Instead they are now quite evenly matched, meaning Nvidia can wait it out for a while yet, and keep raking in cash from existing models rather than spending a ton on creating a new SKU with little going for it.

The 3080 Ti will come out on 7nm ...... But it will be Samsung's 7nm EUV line that's cranking up with a big investment from IBM who already announced a 15 core 120 thread (not a typo) Power10 server CPU

8nm+ was just a stop gap measure .......

Actually on paper the 3080 wins because it has both faster memory and a considerably wider memory buss ..... I don't care how good your cache technology is, a 256 bit wide memory buss with slower memory will always lose to a 384 bit wide memory buss with faster memory ..... If Nvidia goes over to 7nm it's Game Over because then they'll have the higher clock speeds and power efficiency to go along with what they already have ...... AMD is bottlenecked by the memory speed and buss width ...... Plus no decent RT cores and nothing that comes close to competing with Tensor AI cores and the DLSS technology it brings to the table .....
