The PNY RTX 4070, and RTX 4070 in general, does a bit better at 1080p ultra than at 1440p ultra. That's partly because the large L2 cache helps more at lower resolutions, and partly because CPU bottlenecks also come into play. Overall, the 4070 comes in just a bit ahead of the RX 6950 XT, where it was just a bit behind at 1440p.
We could point out that it's fair to expect any $600 graphics card to easily handle 1080p gaming. After all, even the $350 RX 6750 XT averages over 60 fps, though as usual, AMD's GPUs struggle a bit more in some of the ray tracing games. Likewise, AMD's GPUs do better overall in rasterization games. Anyway, let's move on.
The spread in the individual games, when comparing the PNY and Founders Edition 4070 cards, is meaningless. That's as you'd expect, given they have the same reference clock speeds.
The RX 6950 XT remains the closest competition, with a slightly higher price right now. PNY's card just edges past it, by 1% overall, with a 20% lead in the DXR test suite and a 9% loss in the rasterization games.
What the above performance charts don't show (and we'll get to this in a couple of pages) is that the RTX 4070 basically matches the RX 6950 XT in performance while using 178W on average at 1080p, while the RX 6950 XT uses 307W. That means you need a better PSU if you want to run AMD's previous gen halo card, and that's still not accounting for DLSS upscaling or frame generation.
