CPU/GPU Performance & FPS Loss
See what throttling costs you in frames, and what an overclock or power-limit raise can realistically recover.
Estimate how thermal throttling eats your frame rate and how much overclocking or a power-limit raise can claw back. Planning numbers, not a benchmark.

Throttle loss and overclock gain, explained
Scenario: you tuned a build, saw great FPS in reviews, but your own numbers sag under a long session. Heat is usually why — once a chip hits its thermal limit it drops clocks whether or not it could run faster.
Example: a card that benchmarks at 120 FPS but runs 10% hotter in your case might deliver ~108 FPS; a modest +8% overclock (if thermals allow) claws back to ~117 FPS. The calculator shows the net, not just each step.
Boundaries: this is a planning model, not a benchmark. Real throttle depends on your cooler, case airflow, and ambient temperature; overclock gains also depend on silicon lottery and whether thermals actually permit the higher clock.
FAQ: does lowering temperature raise FPS? Often yes — once you were throttling. Cooling headroom is what makes the number real (see Thermal Headroom and Cooling Efficiency).
