Polars vs DuckDB vs ArrowMetal GPU on Apple Silicon: Sort and Group-By Benchmarks

Polars, DuckDB and ArrowMetal on an Apple M4 Max: sort and group-by benchmarks at 10M and 50M rows, wall time next to CPU time, and the rows where the CPU is still ahead.

Apache Arrow Compute on the Apple Silicon GPU: The First Arrow Project I Created That Does It, With 173 Operations Measured Against Polars, pyarrow and pandas

I built ArrowMetal, the first Apache Arrow project I could find that runs compute on the Apple silicon GPU. Apple silicon has one memory for CPU and GPU, and an Arrow buffer in shared Metal memory is already a GPU buffer; no Arrow project used that. ArrowMetal does: 307 of Arrow's 307 compute functions, seven languages, take at 24.2x pyarrow on an M4 Max, and 339 benchmark rows against the fastest CPU idiom of Polars, pyarrow, pandas and numpy, including the 77 where the CPU is still ahead.
