Core i5-12400F with Arc B580: Bottleneck & FPS

At 1080p, a Core i5-12400F + Arc B580 build averages about 78 FPS in AAA games at High settings, with 1% lows near 61 FPS: GPU-limited, CPU has headroom. The Arc B580 is the limiting part at every resolution, so the 6-core Core i5-12400F (LGA1700) still has headroom for about 120 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 245 FPS, enough for a 144 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 66 FPS with a 32% CPU bottleneck. With ray tracing enabled, expect about 41 FPS at 1080p, so turn on DLSS or FSR to get back above 60.
