Intel Arc B580 vs AMD Radeon RX 6800
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 AMD Radeon RX 6800 is faster but costs more. The Intel Arc B580 offers better value for money. Your choice depends on budget vs. performance priority.
Intel Arc B580 vs AMD Radeon RX 6800: Which Should You Buy?
This is not a close race. The AMD Radeon RX 6800 delivers 89.2 fps at 1440p ultra to the Intel Arc B580's 68.5 fps, a 30% gap. Only pick the slower card if it is dramatically cheaper or you need it for a lower resolution.
You pay a 133% premium for the AMD Radeon RX 6800 ($579 against $249) to get 30% more frames. The extra frames do not keep up with the extra cost — the Intel Arc B580 is the better value here.
Two things beyond raw speed: AMD Radeon RX 6800 carries 16GB against 12GB — the deciding factor at 1440p and above with ray tracing or texture packs, and the reason 12GB cards age badly; and the Intel Arc B580 draws 60W less (190W versus 250W), which can mean a smaller PSU and a quieter case; and the Intel Arc B580 is 4 years newer (2024 versus 2020), so it gets longer driver support and newer upscaling and frame generation features.
