Apple M4 — ten cores, four of them performance — macOS, stable Mojo 1.0.0, with nothing else building on the machine. Measured on 5 September 2026; the Iceberg rows on 15 September, the boundary rows on 19 September. [How these were measured](https://magmalake.dev/performance#method).

Every merge also runs its benchmarks on a GitHub runner: [the benchmark history](https://magmalake.github.io/hashes.mojo/benchmarks/). Read it for trends; a shared runner is slower and noisier than the table.
