Core i5-12600K with RX 9070: Bottleneck & FPS

Paired with the RX 9070, the Core i5-12600K delivers roughly 103 FPS at 1440p (1% lows ≈81) in modern AAA games, which our model rates as “well balanced (GPU-bound)”. At 1080p the Core i5-12600K becomes the limit (16% CPU bottleneck at 1080p); from 1440p upward the RX 9070 takes over and the CPU has capacity to spare. In esports titles such as CS2 or Valorant expect around 308 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 70 FPS with a 47% CPU bottleneck. Ray tracing costs this AMD card more than an equivalent NVIDIA GPU: about 52 FPS with RT on at 1440p.

Core i5-12600K + RX 9070: quick answers

Does the Core i5-12600K bottleneck the RX 9070?

1080p: 16% CPU-limited. 1440p: 17% GPU-limited. UW 1440p: 31% GPU-limited. 4K: 50% GPU-limited. At 1440p 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 i5-12600K with RX 9070 get?

About 124 FPS at 1080p, 103 FPS at 1440p, 88 FPS at UW 1440p, 64 FPS at 4K in AAA games at High settings without upscaling. In esports games like CS2 and Valorant it reaches roughly 308 FPS at 1440p.

What is the best upgrade for a Core i5-12600K + RX 9070 build?

None is needed at 1440p. The Core i5-12600K and RX 9070 are well matched, so upgrade only when you want more FPS overall.
