Intel Arc B580 vs AMD Radeon RX 6600 XT
Side-by-side benchmark comparison, specs, pricing, and value analysis.
Benchmark Comparison
Gaming figures are average frames per second, measured by Tom's Hardware GPU hierarchy. Geometric mean of 15 games, ultra settings, no upscaling. Ray tracing figures are DXR-enabled at 1440p. A dash means the card was not tested at that resolution. Productivity and Steel Nomad are synthetic scores on their own scales and are not comparable to the fps columns.

Verdict
The Intel Arc B580 is the clear winner — it offers both better performance and better value.
Intel Arc B580 vs AMD Radeon RX 6600 XT: Which Should You Buy?
This is not a close race. The Intel Arc B580 delivers 68.5 fps at 1440p ultra to the AMD Radeon RX 6600 XT's 52.2 fps, a 31% gap. Only pick the slower card if it is dramatically cheaper or you need it for a lower resolution.
Pricing settles it: the Intel Arc B580 is both faster and 52% cheaper at $249 versus $379. There is no scenario in this pairing where the AMD Radeon RX 6600 XT is the better buy at these prices.
Two things beyond raw speed: Intel Arc B580 carries 12GB against 8GB — the deciding factor at 1440p and above with ray tracing or texture packs, and the reason 8GB cards age badly; and the Intel Arc B580 is 3 years newer (2024 versus 2021), so it gets longer driver support and newer upscaling and frame generation features.
