What this means

The GPU is the limit at this resolution for this workload. Upgrade the graphics card, enable DLSS/FSR/XeSS, or drop settings before spending on a faster CPU.

Performance across resolutions

A pair that looks CPU-limited at 1080p can flip toward GPU-limited at 4K. Tap a card to focus that resolution.

Scores use UserBenchmark Average Bench (CPU vs i9-9900K ≈ 100%, GPU vs RTX 5070 ≈ 100%), then normalized and weighted by resolution and game factor. Estimates for planning — not a substitute for in-game utilization overlays.

Comparing Intel Core i5-14600KF (UserBenchmark Average Bench 116%) with AMD Radeon RX 7800 XT (86%). At 1440p, this pairing reads as gpu-limited with roughly a 17% capability gap.
