Tools
Four tools, one dataset
All four read the same hardware table, so a part's tier score means the same thing everywhere. Every output is a range, because a single number would be a guess wearing a suit.
Data status. The current table holds 24 GPUs and 16 CPUs covering roughly 2019 onward, with price bands rather than exact prices. Bands are reviewed quarterly. Anything marked estimated has a stated margin.
Calculator
PC build calculator
Pick a CPU and GPU, add drives and fans, get total system draw and a PSU size with headroom. Flags socket problems and lopsided pairings.
Estimator
FPS estimator
A frame-rate range from GPU tier, CPU ceiling, resolution and settings. Stated margin of 15%.
Comparison
Parts comparison
Two GPUs or two CPUs side by side on identical rows, with a frame-rate estimate for each.
Checker
Can it run it
Thirty-one of the most-played PC games checked against your parts at your resolution. Deliberately not a full catalogue.
