Benchmark of running Phi-2 LLM on MLX and PyTorch on MPS device

Code for the article about speed comparison of MLX and PyTorch on Apple's M1 MAX GPU: https://medium.com/@koypish/mps-or-mlx-for-domestic-ai-the-answer-will-surprise-you-df4b111de8a0

Installation

• pyenv install 3.11
• pyenv local 3.11

1st option:

• poetry shell

2nd option:

• python -m venv .venv; source .venv/bin/activate
• pip install -r requirements.txt

Run Phi-2 benchmarks

• make mlx
• make mps - for PyTorch on Metal GPU
• make cpu - for PyTorch on CPU

In order to track CPU/GPU usage, keep make track running while performing operation of interest.

Results on M1 Max (MacOS Sonoma 14.1.1)

Structure

• utils.py contains memory measurement utils
• try_phi2_torch.ipynb, try_phi2_mlx.ipynb - benchmarks code
• phi2_mlx.py - code mainly copied from https://github.com/ml-explore/mlx-examples/tree/main/llms/phi2
• plot_metrics.ipynb - contains code to parse and analyze output of powermetrics (run by make track)
