Here are some benchmarks that other people did (both vs CPU and vs GPU):

- vs OpenVINO + ONNX on CPU - more than 2x faster

- vs PyTorch (CPU: i7 11800H, GPU: RTX 3080 Laptop):

- whisper.cpp on Xeon processor

Also, my implementation is focused for performance on M1 chips and it looks like most of the Python frameworks do not support it properly yet, so I cannot make a proper benchmark.

Additionally, my implementation can also run the "large" model on an android phone (Samsung A52) - would be interesting to see how this compares with existing implementations:
