Verdict
AMD Radeon RX 580 4GB 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 RX 580 4GB comes out ahead by around 11% 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 RX 570 8GB with the RX 580 4GB.
Which is better, the RX 570 8GB or the RX 580 4GB?
On average at 1080p, the RX 580 4GB is 11% faster than the RX 570 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 570 8GB averages 5 FPS and the RX 580 4GB 5 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 11% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
570 8GB vs 580 4GB: what's the real difference?
In performance, the RX 580 4GB beats the RX 570 8GB by around 11% 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 570 8GB and the 580 4GB on price, the price and $/FPS section above can help you decide.
