/ Stenfox GPU · Standalone product
NewStress test and benchmark any GPU.
A dedicated product for graphics processors, separate from computer diagnostics. From laptop chips to data-centre AI accelerators, every GPU runs the same protocol and leaves with a score, a grade and a signed report.

Two modes, side by side.
Stress test
Sustained full load until weaknesses show, inside safe limits. The temperature curve is recorded through warm-up, sustained load and cool-down.
Benchmark
Compute throughput, memory bandwidth, VRAM and peak temperature are measured, then turned into a score and a grade for resale.

The protocol, in six stages.
- 01
Compute stress
Sustained load, every result checked for correctness.
- 02
VRAM integrity
Patterns written, read back and compared.
- 03
Thermal behaviour
Hotspot and throttling under load.
- 04
Load transitions
Idle and peak alternate to expose instability.
- 05
Fault detection
Driver errors, disconnects and resets.
- 06
Safety supervision
Slows or stops at conservative limits.

/ Honest comparison
From a boot test to a graded, signed result
Most GPUs are resold after a visual check or a quick boot. Stenfox GPU runs a repeatable protocol and records what it found.
/ FAQ
Frequently asked questions
Which GPUs does Stenfox GPU support?
Integrated GPUs in Windows laptops and desktops, discrete PCIe cards (consumer and workstation), external eGPU enclosures, and data-centre / AI accelerators.
Isn't this already in Stenfox Computing?
Stenfox Computing includes a basic GPU check among its hardware tests (26 on Mac, 23 on Windows laptops). Stenfox GPU is a separate, dedicated product for full stress testing and benchmarking.
What if a GPU can't run a full test?
The report always states the depth that ran: full test, limited (monitoring only) or identification only.
Is it a data wipe?
No. A GPU is not storage media. Stenfox GPU is a health, performance and grading test.
