AMD RX 580 8GB vs AMD RX 6500 XT

How much faster one is than the other, and the resolution at which that difference turns into real frames. Reference: AMD Ryzen 9 7900, 32 GB of RAM.

SHORT ANSWER

The AMD RX 580 8GB and the AMD RX 6500 XT perform the same in practice: a 1% average difference is not perceptible while playing. Decide on price, power draw or availability.

WHERE IT STARTS MATTERING

Real-world advantage of the AMD RX 580 8GB over the AMD RX 6500 XT at each resolution, paired with an AMD Ryzen 9 7900. At low resolution the processor caps both cards equally, so the faster one delivers nothing extra until the load moves onto the graphics card.

HOW THIS IS CALCULATED

The per-game frame rates are the ceiling each card sustains on its own at that resolution, with no processor limiting it. The resolution table does include the processor, because that is where you see whether the difference reaches you.

Native resolution, no upscaling and no frame generation. Measured model error · Methodology
