Intel Arc B580 vs NVIDIA GeForce RTX 3080
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.

Intel Arc B580 vs NVIDIA GeForce RTX 3080: Which Should You Buy?
This is not a close race. The NVIDIA GeForce RTX 3080 delivers 96.4 fps at 1440p ultra to the Intel Arc B580's 68.5 fps, a 41% gap. Only pick the slower card if it is dramatically cheaper or you need it for a lower resolution.
You pay a 181% premium for the NVIDIA GeForce RTX 3080 ($699 against $249) to get 41% 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: the Intel Arc B580 draws 130W less (190W versus 320W), 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.
