Resolution guide

Best resolution for a CPU bottleneck

Resolution changes the bottleneck because it changes how much work the GPU must do. A PC that looks CPU-limited at 1080p can look more balanced at 1440p and become GPU-limited at 4K.

1080p exposes CPU limits

At 1080p, modern GPUs can often render frames quickly. If the CPU cannot feed enough frames, lowering graphics settings will not help much. This is why competitive high-refresh setups need strong CPU performance.

1440p often balances the build

1440p adds enough pixel load that the GPU works harder, while still keeping frame rates practical for many midrange and upper-midrange cards. For many gaming PCs, it is the most balanced resolution.

4K shifts more work to the GPU

At 4K, GPU performance and VRAM matter more. A CPU bottleneck can still happen in simulation-heavy games, but graphics workload usually dominates.

The best resolution is the one that matches your monitor, target FPS, and preferred game settings. Use the calculator to compare the same CPU/GPU pair across 1080p, 1440p, and 4K.
