Ranked by how little performance the pairing wastes, not by which processor is fastest. The fastest chip pairs well with everything, which makes it a useless recommendation.

What to expect from a Radeon RX 580 8GB

This card sits in the lower part of the range we model. It will run modern titles at 1080p with settings turned down, and it will be the limiting component in almost any pairing — which means there is no sense pairing it with an expensive processor.

If frame rates are disappointing, the card is where an upgrade will help. Nothing else in the system is holding it back.

8 GB is this card's real limit

8 of the 16 titles we model exceed 8 GB at 1440p and high settings. On this card memory, not shader throughput, is the thing that will make modern games stutter. Texture quality is the setting to lower first, and it usually costs less visual fidelity than the alternatives.

A note on age

Released in 2017, this card is 9 years old. Beyond raw speed, older hardware misses features newer engines increasingly assume — mesh shaders, hardware ray tracing, and the newest upscalers. A modern title may run worse than these numbers suggest, or refuse to launch, for reasons the model cannot see.
