Verdict
NVIDIA GeForce RTX 4080 Super 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 RTX 4080 Super comes out ahead by around 17% 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 RTX 4080 Super with the RTX 3090 Ti.
Which is better, the RTX 4080 Super or the RTX 3090 Ti?
On average at 1080p, the RTX 4080 Super is 17% faster than the RTX 3090 Ti. 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 RTX 4080 Super averages 62 FPS and the RTX 3090 Ti 50 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 17% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
4080 Super vs 3090 Ti: what's the real difference?
In performance, the RTX 4080 Super beats the RTX 3090 Ti by around 17% 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 4080 Super and the 3090 Ti on price, the price and $/FPS section above can help you decide.
