Verdict
AMD Radeon RX 7900 XTX wins in 10 out of 10 games
At CheckFPS we measured both cards across 10 popular games at 1080p, 1440p and 4K on a reference CPU. The RX 7900 XTX comes out ahead by around 3% more FPS on average, and that lead holds up as resolution climbs. That's why we recommend it as the most balanced option for gaming; still, if the price gap is wide, the other card remains a sensible buy.
Frequently asked questions
Common questions when comparing the RX 7900 XTX with the RTX 4080 Super.
Which is better, the RX 7900 XTX or the RTX 4080 Super?
On average at 1080p, the RX 7900 XTX is 3% faster than the RTX 4080 Super. The best one for you depends on your resolution, budget and whether you prioritise ray tracing or price.
Which is better at 4K?
At 4K Ultra, the RX 7900 XTX averages 64 FPS and the RTX 4080 Super 62 FPS across the most popular games. For smooth 4K, enabling upscaling (DLSS/FSR) helps on both.
Is it worth paying more for the faster one?
At 1080p or 1440p the FPS gap may not justify the extra cost; at 4K or with ray tracing the faster card matters more. Check the by-resolution table to decide.
Which has better ray tracing and upscaling?
AI upscaling (DLSS on NVIDIA, FSR on AMD, XeSS on Intel) raises FPS on both; for ray tracing, GeForce RTX cards usually lead. See each card’s support above.
How big is the FPS difference between them?
On average across top games, the gap is around 3% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
7900 XTX vs 4080 Super: what's the real difference?
In performance, the RX 7900 XTX beats the RTX 4080 Super by around 3% more FPS on average at 1080p — the gap shifts a bit by resolution, as shown in the table above. If you're torn between the 7900 XTX and the 4080 Super on price, the price and $/FPS section above can help you decide.
