Intel Arc A770 vs Intel Arc B580
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 A770 vs Intel Arc B580: Which Should You Buy?
The Intel Arc B580 is 15% faster at 1440p ultra (68.5 fps against 59.8 fps). That is roughly one settings notch — enough to matter if you are chasing a specific refresh rate, not enough to rescue a bad price.
Pricing settles it: the Intel Arc B580 is both faster and 32% cheaper at $249 versus $329. There is no scenario in this pairing where the Intel Arc A770 is the better buy at these prices.
Two things beyond raw speed: Intel Arc A770 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 is 2 years newer (2024 versus 2022), so it gets longer driver support and newer upscaling and frame generation features.
