Arc B570 vs Arc B580: Gaming Performance & Bottleneck (2026)

With a Ryzen 7 9800X3D at 1440p High, the Arc B580 averages 55 FPS in AAA games to the Arc B570's 47. That 17% lead grows to 23% at 4K. Newer isn't faster here: the Arc B580 came out 1 year before the Arc B570 and still leads in raster performance. The order holds at 1080p (17% apart), so the Arc B580 is the quicker card at every resolution. With ray tracing on at 1440p they manage 23 and 29 FPS respectively, so plan on DLSS, FSR or XeSS upscaling. In esports games like CS2 or Valorant at 1080p they reach 213 and 250 FPS, enough for a 144 Hz monitor. At 4K the Arc B570 manages 27 FPS native, and XeSS Quality lifts that to about 39. The Arc B580 also has more memory (12 GB vs 10 GB), and 10 GB is short of the ~11 GB that 4K High needs. To stay under a 10% CPU bottleneck at 1440p, both need only a Ryzen 5 3600-class CPU.

Which should you buy?

Buy the Arc B580 if you want the faster card: it's 23% ahead at 4K. The Arc B570 is the better buy only if it costs at least 17% less, the gap at 1440p, because then it delivers more frames per dollar. Already own the Arc B570? The Arc B580 is only 17% faster at 1440p and is older hardware, so switching is rarely worth it.

Buy the Arc B570 if…

  • you want the newer card (2025) with the longer driver and feature support ahead of it.
  • it costs at least 17% less than the Arc B580, which makes it the better value per frame.

Buy the Arc B580 if…

  • you want the most FPS: it's 23% faster at 4K and 17% at 1440p.
  • you play with ray tracing: 29 vs 23 FPS at 1440p.
  • you play at 4K or use high-resolution texture packs: 12 GB of VRAM vs 10 GB.

Arc B570 vs Arc B580: quick answers

Is the Arc B570 faster than the Arc B580?

No. The Arc B580 is about 23% faster at 4K and 17% faster at 1440p in AAA games at High settings. With ray tracing on at 1440p the Arc B570 gets about 23 FPS and the Arc B580 29 FPS.

How many FPS do the Arc B570 and Arc B580 get?

With a Ryzen 7 9800X3D at High settings in AAA games, the Arc B570 averages about 67 FPS at 1080p, 47 at 1440p and 27 at 4K. The Arc B580 averages 78, 55 and 33 FPS. DLSS, FSR or XeSS upscaling adds roughly 40% where the graphics card is the limit.

What CPU do I need for the Arc B570 or Arc B580?

To keep the CPU bottleneck under 10% at 1440p, the Arc B570 needs a Ryzen 5 3600 or faster and the Arc B580 needs a Ryzen 5 3600 or faster. At 1080p you need a faster CPU for the same result, and at 4K a slower one is fine. A slower CPU narrows the gap between the Arc B580 and the Arc B570.
