We shall wait for real world benchmarks to address the raster performance increase.
The bold claim "5070 is like a 4090 at 549$" is quite different if we factor in that it's basically in DLSS only.
it's actually a lot worse than it sounds even. The 5070 is like a 4090 is when the 5070 has multi frame generation on and the 4090 doesn't. So it's not even comparable levels of DLSS, the 5070 is hallucinating 2x+ more frames than the 4090 is in that claim
Based on non-DLSS tests, it seems like a respectable ~25%.
Respectable outright, but 450W -> 575W TDP takes the edge off a bit. We'll have to see how that translates to at the wall. My room already gets far too hot with a 320W 3080.
