Frequently asked questions
Common questions when comparing the RX 6900 XT with the RTX 3090 Ti.
Which is better, the RX 6900 XT or the RTX 3090 Ti?
On average at 1080p, the RTX 3090 Ti is 18% 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 RX 6900 XT averages 42 FPS and the RTX 3090 Ti 54 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 18% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
