Field notes
The calculation compares model weights, KV cache, and a compute buffer with memory available on the selected hardware. Speed estimates use a memory-bandwidth model calibrated against 52 public benchmarks. The page gives different stated error bands depending on the hardware and conditions, and separates measured results from calibrated and theoretical ones.
