3-Stage Forensic Hardware Benchmark
UserBenchmark runs a three-phase forensic stress test entirely inside your browser — no download, no install, no elevated permissions. It measures real, sustained performance under load across CPU multi-core compute, GPU shader throughput, and GPU ray-tracing speed. The result is a forensic grade (S through D) plus a class archetype describing your hardware's behavioral fingerprint.
How to Start
Hold the start button on this page for one second to arm the test sequence. The benchmark automatically advances through all three stages and redirects to your results page when complete. Total run time is approximately 2–3 minutes depending on your GPU's path-tracing speed.
The Three Stages
60 seconds of sustained multi-threaded compute. Measures ops/sec peak, valley, and thermal decay percentage. High decay indicates thermal throttling or inadequate cooling.
60 seconds of sustained GPU shader workload. Measures FPS peak, valley, decay %, and VRAM pressure (low / moderate / high / critical). Detects GPU thermal throttling under load.
Variable-duration BVH ray-tracing benchmark (BMW M4 scene). Score = time to reach 150 accumulated samples. Faster convergence = higher GPU ray-tracing score. Tests VRAM bandwidth and render consistency.
Scoring and Grading
Each system receives a forensic grade derived from measured decay and consistency values:
- S — Exceptional: CPU decay ≤3%, GPU decay ≤3%, PT consistency ≥95%
- A — Strong: CPU decay ≤8%, GPU decay ≤8%, PT consistency ≥85%
- B — Good: CPU decay ≤15%, GPU decay ≤15%, PT consistency ≥70%
- C — Moderate throttling: decay ≤25%, consistency ≥55%
- D — Significant degradation across one or more stages
The system is also assigned a class archetype (SOVEREIGN, AWAKENED, IRON WALL, GLASS CANNON, CPU CHAINED, THERMAL WRAITH, GHOST RIG, OPERATIVE, or INITIATE) based on its complete forensic profile.
What You Get After the Test
- Grade badge (S/A/B/C/D) and class archetype name
- Thermal health score (0–100 composite)
- Synergy score — CPU+GPU balance indicator
- Path-tracing samples-per-second score
- Silicon Doctor diagnosis — headline finding, primary cause, evidence, prescriptions
- Crowd percentile comparison against the same CPU+GPU hardware pair
