One run. Three sustained workloads.

The benchmark measures the system running it. It does not estimate performance from hardware names or specifications. Keep the tab foregrounded, close unnecessary background work, and compare repeat runs under similar conditions.

Stage 1 · 60 seconds

CPU sustained throughput

Parallel Web Workers record operations per second, responsiveness, stability, and performance decay.

Stage 1 details
Stage 2 · up to 80 seconds

Adaptive GPU raster pressure

A rendered scene and calibrated pressure workload record raster work, visual pacing, backend, stability, and a stable workload ceiling.

Stage 2 details
Stage 3 · 150 samples

Path-tracing convergence

A progressive scene records samples per second and sample-time consistency until the fixed work target completes.

Stage 3 details

What you receive

The browser cannot directly read temperatures, clocks, voltage, package power, fan speed, or exact utilization. Decay is a diagnostic signal, not a temperature reading or proof of one cause.
