# Benchmarks to compute 16,777,216 nonces
_Each test is 128 samples of one pass (dispatch or frame) at zero difficulty with no early exit_

## Summary
- Chromium WebGPU and Firefox WebGL are the clear winners
- Chromium WebGL seems to suffer from an Nvidia driver issue
- Firefox WebGPU exhibits a strange implementation bottleneck
  - It seems to restricts each pass to a minimum of 200ms
  - Not shown here: This minimum is higher or lower depending on dispatch size
- Safari WebGPU performance was maintained between versions
- WebGL downsampling shader minimized readback lag and thus enabled much larger frames
- WebGPU improved dramatically on non-mobile platforms, almost halving frame times
- Maximum WebGL canvas size varies
  - Safari only supports up to 4096x4096
  - Chromium supports up to 5760x5760
  - Firefox supports up to a whopping 8192x8192 which actually makes it competitive with WebGPU
