Frequently asked questions
Common questions when comparing the GTX 1660 Ti with the RX 6600M.
Which is better, the GTX 1660 Ti or the RX 6600M?
On average at 1080p, the GTX 1660 Ti is 0% faster than the RX 6600M. 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 GTX 1660 Ti averages 9 FPS and the RX 6600M 10 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 0% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
