Looking at Shadow of the Tomb Raider, the overall trend here is pretty similar to Red Dead Redemption 2. At 1440p, the 6900 XT is 6% faster than the RTX 3080, but 5% slower than the RTX 3090.
And then again at 4K, Ampere comes on strong, and we can see the RTX 3080 and 6900 XT are now effectively matched, delivering 76-77FPS on average. The 6900 XT is also 11% slower than the RTX 3090.
