BrowserGPU is a JavaScript framework that synthesizes functional GPUs in the browser by logically building transistors, gates, and cores from binary ops – presets include H100 and RTX 4090.

Does BrowserGPU actually run real workloads?

Yes, it processes compute tasks via JS objects mimicking CUDA cores, though performance lags hardware due to event loop limits – great for demos, not data centers.

Is BrowserGPU just an April Fools joke?

Tagged as such, but the logic holds: GPUs are math, JS expresses it perfectly. Expect real forks evolving this into WebGPU tools.
