Processor—
—
Run the sweep to rate your CPU.
MOps/s means millions of operations per second — how many small calculations your processor runs each second. It’s the raw speed of your PC’s “brain”: higher means games, apps and everyday tasks respond faster and you can juggle more at once without slowdowns.
Graphics—
—
Run the sweep to rate your GPU.
FPS means frames per second — how many full images your graphics card draws each second in our test scene. Higher is smoother: under ~30 looks choppy, 60 feels fluid, and 120+ is very smooth for fast-paced games.
Internet—
—
Run the sweep to rate your connection.
Mbps means megabits per second — how much data your connection moves each second. Higher means quicker downloads, sharper video calls and streaming without buffering. (It takes 8 megabits to make 1 megabyte.)
Storage—
—
Run the sweep to rate your drive.
MB/s means megabytes per second — how fast your drive reads and writes files. Higher means games, programs and the system itself load and open faster, so the whole PC feels snappy instead of sluggish.

The browser's own prediction of whether each codec plays smoothly and on dedicated hardware (power-efficient) at each resolution. Then optionally play a real clip to measure dropped frames.
What this means. Single-core speed drives most games; multi-core helps editing, compiling and heavy multitasking. These are JavaScript scores — fair to compare across browsers, but not against native benchmark tools.

What this means. Average FPS is the headline; the 1% low is the honest one — how rough the worst moments feel. TFLOPS is raw compute. Browsers can't read GPU temperature or true utilisation.

Latency—
What this means. Speed (Mbps) wins downloads, but latency decides how games and calls feel. This is browser-measured throughput to a nearby edge server, not your raw ISP line.

What this means. Upload matters for streaming, video calls and cloud backups. Measured to your own server, with a Cloudflare fallback.

What this means. Sequential speed looks big on a spec sheet; real load times track random speed. Browsers can't bypass the OS cache, so treat read numbers as a floor — a larger test file gives a truer figure.
