Don't be so sure about that.

If the 50% efficiency improvement over Navi/RDNA for RDNA2 holds true, then competing with the 3090 shouldn't be out of question. Even with just 64 CU and the clock speeds of the 5700XT the 2080Ti would be beaten by a country mile due to the latter's low clock speeds. If NVidia don't clock the 3080 and 3090 with at least 200 Mhz more than the 2080Ti did, then Big Navi could spell major trouble to NVidia.

You mention the 50% improvement from AMD that, and I can't stress this enough, is just their target goal that they may achieve it or not, we won't know until launch. But aren't you forgetting that Ampere will also bring performance improvements? Don't you remember the rumors from earlier this year that talked about a 40% improvement?

AMD won't be the only one to improve here, and during the last gens we've seen how the newer xx70 card performed like the xx80Ti from the previous gen (970 ∼ 780Ti, 1070 ∼ 980Ti and the 2070 failed that because of the focus in Ray Tracing, tho the Super variant matched the performance of the 1080Ti).

If that pattern follows again this gen, and even wif it ends having ith the same shader/core count as the rumor from yesterday, the 3080 will be much faster than the 2080Ti thanks to the improvements of the new architecture and the jump to 7nm, that will allow it to clock much higher.

Don't worry, I didn't forget it - in fact,I hope NVidia does good on those improvements. But my fear was more fueled by the TGP of 350W for the 3090, which simply doesn't sound like the performance per watt improvement is really that big unless the clock speed also went up quite a bit.

Personally I am expecting AMD's RDNA2 to get the least amount of real world gains compared to Nvidia's Ampere. The reason is there isn't much of a node shrink with RDNA2, just an architectural change which for all we know is just adding in ray tracing. Meanwhile Nvidia is going to have both a node shrink + architectural. I wouldn't be surprised if AMD's RDNA 2 pricing is close to Ampere as well since they couldn't massively undercut them with RDNA 1 without tensor cores and without ray tracing so they certainly can't do it with Ray Tracing.

Also this is AMD's first attempt at ray tracing vs Nvidia's second generation ray tracing. Hopefully their performance is good but I have lots of doubts that it can even keep pace with 3080.

WTF? AMD has already denied that rumor and said it's an architectural redesign to make it consume much less for the same performance. That's like if I had said that Ampere would be just another rehash of Maxwell with Raytracing slightly more firmly bolted on than with Turing.
