CPU/GPU Pairing Checker

Check whether a CPU and GPU class is a sensible match for your resolution and workload. The result stays honest: no fake bottleneck percentages.

Good pairing

Modern 6-core · Ryzen 5 5600X / i5-12400F and Upper-mid GPU · RTX 4070 / RX 7800 XT are a sensible match for 1440p gaming use.

  • CPU and GPU classes are close enough for a balanced first-pass plan.
  • 1440p does not create an obvious one-sided mismatch here.
  • Exact game, settings, RAM, cooling, and drivers can still change the result.

Sources and assumptions

  • This checker uses broad CPU/GPU classes for planning, not exact benchmark data.
  • No bottleneck percentage is shown because exact percentages are usually false precision.
  • Resolution and workload change the answer: 1080p high-FPS leans CPU, 1440p/4K leans GPU.
  • This route is deterministic public UI logic and does not read from D1.

FAQ

Can a checker give an exact bottleneck percentage?

No. Exact percentages are misleading because games, settings, RAM, drivers, cooling, and target FPS change the result. This tool gives a planning category instead.

Why does resolution matter?

Lower resolution and very high FPS targets lean more CPU-heavy. Higher resolution and visual settings usually make the GPU matter more.

What should I do after the pairing check?

Use the full configurator to include PSU, RAM, budget, form factor, and workload priorities before buying parts.
