Browser GPU diagnostic

Verify that this browser can create a WebGPU device, execute a compute shader, and read the result back correctly. The check stays on this computer and never claims customer work.

Experimental

What it verifiesAdapter, device, compute, and readback.

What stays privateThe test data never leaves your browser.

What it cannot knowTotal or available GPU memory.

Diagnostic status
Ready to inspect this browser

The compute timing includes browser submission and result readback. It is not a hardware benchmark.

The diagnostic performs six local checks

  1. 01Secure browser context
  2. 02WebGPU API availability
  3. 03High-performance adapter access
  4. 04Logical device creation
  5. 05Compute shader execution
  6. 06Result readback and validation
