After a run, PCBenchmark shows a single score out of 100, a system grade and a run quality label. The single number is convenient, but the report behind it tells you much more about your PC.
The overall score
The overall score combines the CPU, GPU and memory phases into one value from 0 to 100. It is meant for quick comparisons between systems tested with the same engine version. A gaming desktop with a recent graphics card will land far higher than an office laptop with integrated graphics, and that gap is exactly what the score is designed to show.
The category results
Below the score, every phase keeps its raw result:
| Phase | What it measures | Unit |
|---|---|---|
| CPU single | Sustained work on one browser worker | operations per second |
| CPU multi | Combined work across several workers | operations per second |
| Compression proxy | Mixed integer and memory work | MB per second |
| GPU | Compute and rendering through WebGPU or WebGL 2 | estimated shader workload, FPS |
| Memory | Copying and random access across a large buffer | transfer rate and latency |
If two PCs have a similar overall score, these rows usually explain the difference. One may have a faster processor, the other a stronger graphics chip.
Run quality
The run quality label tells you how much to trust a result. A run can be marked lower when the tab lost focus, the device throttled, or the timings varied too much between samples. For a clean result, plug in your laptop, close heavy applications and keep the benchmark tab in front until it finishes.
Compare like with like
Results from WebGPU and WebGL 2 are different benchmark families and are never ranked against each other. The same applies to different engine versions. When you compare your PC with an entry on the leaderboard, check that both runs used the same backend.
