What PCBenchmark does
PCBenchmark is a free online benchmark and stress test for desktop PCs, laptops and many phones. It runs real CPU, GPU and memory workloads inside the browser and combines them into a score from 0 to 100, with the raw result of every phase kept in the report.
Next to the benchmark, the site offers a leaderboard of public results, a bottleneck calculator that compares a processor, a graphics card and a memory configuration, and guides that explain how to read the numbers.
How the test works
Processor phases run in Web Workers, graphics phases use WebGPU or WebGL 2, and the memory phase copies and reads a large buffer. Warm-up passes are excluded from timing, and every result stores the engine and scoring version, so only comparable runs are ranked together.
Browsers deliberately hide some hardware details, such as exact RAM size, video memory and temperatures. The methodology page explains every workload and every limit in detail.
The hardware catalog
The catalog lists more than 6,000 processors and graphics cards. Most entries come from official manufacturer specifications; newer models are added from visitor suggestions after they are checked against the manufacturer’s product pages.
