What this means

This pairing looks well matched at the selected resolution for this workload. Spend on the display, storage, or cooler before chasing a one-sided upgrade.

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 AMD Ryzen 7 5800X3D (UserBenchmark Average Bench 102%) with NVIDIA GeForce RTX 4070 (80%). At 1440p, this pairing reads as balanced with roughly a 12% capability gap.
