How our FPS estimates work
Every number on this site comes from one deterministic model — here's exactly what goes into it, and what it can and can't tell you.
The short version
GamerSpecs estimates FPS with a benchmark-anchored performance model, not live measurements. Every GPU and CPU in our database carries a relative performance score normalized to two anchors: the GeForce RTX 4060 = 100 for graphics cards and the Intel Core i5-13400 = 100 for processors. Every game carries a demand profile. An estimate is the deterministic combination of the two — the same inputs always produce the same number, never a random one.
What goes into an estimate
- GPU score. Curated relative gaming performance for 230+ desktop and laptop GPUs plus popular integrated graphics, cross-checked against published benchmark data.
- CPU score. Gaming-weighted (single-thread-heavy) scores for 260+ processors, because most games care more about per-core speed than core count.
- Game demand profile. How heavily a title leans on GPU vs CPU, its baseline frame rate on reference hardware, and its VRAM and RAM appetite.
- Resolution scaling. 1440p and 4K apply per-resolution scaling factors — GPU load grows faster than CPU load as resolution rises.
- Memory penalties. Falling below a game's recommended RAM or exceeding the card's VRAM applies realistic frame-rate penalties (texture thrashing is modeled, not ignored).
What the numbers mean — and don't
An estimate answers "will this be playable, and roughly how smooth?" — it is not a lab benchmark of your exact PC. Real-world results vary with drivers, cooling, power limits, background apps, game patches and scene complexity. Treat a number as the middle of a realistic range: a card estimated at 60 FPS may deliver 50–75 depending on the scene and settings.
Requirement verdicts (pass/fail) compare your hardware's scores against each game's official minimum and recommended specs as published by the developer, resolved onto the same benchmark scale.
Corrections
The model is tuned continuously. If a verdict or estimate looks wrong for hardware you actually own, tell us on the feedback page — real-rig reports are the fastest way the data improves.
