Here we present frame rate figures for each graphics card, averaged across all 12 games on test today. These figures can disguise significant variations in performance from game to game, but provide a useful overview of the sort of performance you can expect at each resolution tested.
Looking at the big picture overview, the RX 7900 XTX averages just under 181FPS at 1440p. That makes it 5% faster than the RTX 4080, 11% slower than the RTX 4090, while it's a 32% improvement over the RX 6950 XT.
At 4K, the 7900 XTX does look a bit better versus the RTX 4080 as it's 7% faster on average here, but also 19% slower than the RTX 4090. Compared to the previous generation AMD flagship, the XTX is 39% faster than the 6950 XT.
