Browser Benchmark
Three quick benchmarks run entirely in your browser: CPU arithmetic throughput, WebGL triangle rendering, and memory bandwidth. Results vary with background tabs, power mode, and thermal state — keep the tab focused for the most accurate numbers.
CPU
Tight arithmetic loop running for 2 seconds. Measures raw JavaScript execution throughput.
Not run yet.
GPU
Renders 2,000 textured triangles per frame via WebGL for 2 seconds. Reports frames/sec and effective triangles/sec.
Not run yet.
Memory
Allocates a 64 MB Float64Array, fills it, then reads it back. Measures combined read + write bandwidth.
Not run yet.
How to read the ratings
Ratings compare against rough baselines for typical consumer hardware (Low = entry-level mobile, Very High = flagship desktop or GPU). They're a sanity check, not a precise benchmark — a phone on battery saver will look much slower than the same phone plugged in.
