Core i5-10400F with Arc B580: Bottleneck & FPS

The Core i5-10400F and Arc B580 are well balanced at 1080p: about 75 FPS on average in AAA games at High settings, with 1% lows around 57 FPS. The Arc B580 is the limiting part at every resolution, so the 6-core Core i5-10400F (LGA1200) still has headroom for about 88 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 218 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 48 FPS with a 50% CPU bottleneck. With ray tracing enabled, expect about 41 FPS at 1080p, so turn on DLSS or FSR to get back above 60.

Core i5-10400F + Arc B580: quick answers

Does the Core i5-10400F bottleneck the Arc B580?

1080p: 11% GPU-limited. 1440p: 38% GPU-limited. UW 1440p: 48% GPU-limited. 4K: 62% GPU-limited. At 1080p the CPU keeps up, so this is a sensible pairing. A GPU-limited result is the normal, healthy state for gaming.

How many FPS does the Core i5-10400F with Arc B580 get?

About 75 FPS at 1080p, 54 FPS at 1440p, 46 FPS at UW 1440p, 33 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 218 FPS at 1080p.

What is the best upgrade for a Core i5-10400F + Arc B580 build?

None is needed at 1080p. The Core i5-10400F and Arc B580 are well matched, so upgrade only when you want more FPS overall.
