I wish it was so, but to be honest I don't see it happening. AMD themselves said RDNA 2 is a 1.5x performance per watt improvement over RDNA 1, while Nvidia is claiming a 1.9x performance per watt improvement over Turing, and Turing was already ahead of RDNA in performance per watt, so at the very least Nvidia will win on performance per watt it seems. 3080 already has a massive TDP of 320 watts, if AMD is indeed behind in performance per watt, I just can't see them beating the 3080 on performance. I suspect the rumor that the top of the line RDNA card offers 30% better performance than 2080 ti is true, which would put it between the 3070 and 3080 in terms of performance.
Where AMD can shine those is price/performance ratio. If they can offer better than 3070 performance at a lower price, say $450, they will be in a good position for sure. AMD should also aim to get their mid-range RDNA 2 cards out this year, since it seems like mid-range Ampere might not come until next year.
Ampere doesn't have 1.9x Perf/W improvement, it has around 1.15x, w8 for reviews. 1.9x is just a marketing number.
Geforce 3080, around 40% faster than geforce 2080 ti, in 4k (4.5/3.2 = 40%). I expected Geforce 3090 (350W) to land 50% faster than 2080 ti in 4k games:
Note this is Nvidia choosing games that favor them too, there's nothing to worry about, RDNA2 will beat this.
