Frequently asked questions
Common questions when comparing the RX 580 8GB with the GTX 1660.
Which is better, the RX 580 8GB or the GTX 1660?
On average at 1080p, the GTX 1660 is 28% faster than the RX 580 8GB. 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 580 8GB averages 6 FPS and the GTX 1660 8 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 28% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
