Core i5-13400F with Arc B580: Bottleneck & FPS

The Core i5-13400F and Arc B580 leave the CPU with plenty of spare headroom at 1080p: about 78 FPS on average in AAA games at High settings, with 1% lows around 61 FPS. The Arc B580 is the limiting part at every resolution, so the 10-core Core i5-13400F (LGA1700) still has headroom for about 126 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 247 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 69 FPS with a 29% CPU bottleneck. With ray tracing enabled, expect about 41 FPS at 1080p, so turn on DLSS or FSR to get back above 60.

Core i5-13400F + Arc B580: quick answers

Does the Core i5-13400F bottleneck the Arc B580?

1080p: 38% GPU-limited. 1440p: 57% GPU-limited. UW 1440p: 64% GPU-limited. 4K: 74% 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 i5-13400F with Arc B580 get?

About 78 FPS at 1080p, 55 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 247 FPS at 1080p.

What is the best upgrade for a Core i5-13400F + Arc B580 build?

At 1080p, the most effective upgrade is the RTX 4070 or RX 9060 XT 16GB. Use the calculator to check other resolutions and settings.
