Verdict

NVIDIA GeForce RTX 3080 Ti 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 3080 Ti comes out ahead by around 4% 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 3080 Ti with the RX 6900 XT.

Which is better, the RTX 3080 Ti or the RX 6900 XT?

On average at 1080p, the RTX 3080 Ti is 4% faster than the RX 6900 XT. 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 3080 Ti averages 44 FPS and the RX 6900 XT 39 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 4% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.

3080 Ti vs 6900 XT: what's the real difference?

In performance, the RTX 3080 Ti beats the RX 6900 XT by around 4% 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 3080 Ti and the 6900 XT on price, the price and $/FPS section above can help you decide.
