01 / WORKLOAD BREAKDOWN

Performance by workload.

CPU and GPU use the current adaptive scale for the same workload, mode and graphics backend. When a faster validated device becomes the reference, older comparable scores are projected onto the new scale without changing their raw measurements. VRAM remains a pass/fail diagnostic.

02 / RELATIVE PERFORMANCE

What sits above and below this hardware.

Each ladder uses one consistent source. Validated PCBenchmark medians take priority when the matching workload cohort has enough approved runs; until then, the report shows a clearly marked catalog estimate.

CPU POSITION

Apple M5 comparison ladder

ESTIMATE

Comparison unavailable
The catalog does not contain enough core and clock data to build a responsible CPU estimate for this model.

GPU POSITION

Apple M3 Ultra GPU comparison ladder

ESTIMATE

Comparison unavailable
The catalog does not contain a trustworthy theoretical compute reference for this GPU.

03 / STABILITY96.6%

Sustained-load signal

This signal summarizes frame delivery during the timed graphics phase. It can reveal an inconsistent run, but it is not a temperature sensor.

BROWSER BENCHMARK, NOT HARDWARE ATTESTATION

Read this result in its proper context.

It measures this browser’s execution path under the conditions of this run. Cooling, power mode, drivers, background processes and browser updates can change the outcome. CPU/GPU names may be supplied manually or matched to the catalog from a browser hint. Compare only matching suite, mode, engine version and graphics backend. NOT RUN categories were not measured and are not zero-performance results.
