Frequently asked questions

Common questions when comparing the R9 390X with the RX 580 8GB.

Which is better, the R9 390X or the RX 580 8GB?

On average at 1080p, the RX 580 8GB is 19% faster than the R9 390X. 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 R9 390X averages 5 FPS and the RX 580 8GB 6 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 19% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
