Check your GPU

Every case below was frozen by running real PyTorch and comparing the answer position by position. This page asks your browser the same questions on your own GPU. Nothing is uploaded — the run happens in this tab and the result stays on this page.

Why this page exists

Every vendor claim in this repository has come from one laptop, and one of them was wrong for months: a 845 / 845 pass was written down as two vendors confirmed when the adapter had been google / swiftshader the whole time. The pass was real; the sentence about what it proved was not.

So the adapter is printed with the count, always, and in the same breath. A run that says google / swiftshader is also a real result — that is WebGPU's own CPU path and the values are still values. It just is not a statement about a GPU.

If you have a card this repository has never seen, this is the whole of what it takes to tell us: press the button and paste the first line into an issue.
