Apple M4 Max (40-core GPU, 128GB)

The machine most MLX benchmarking is done on, which is why it is here: a large share of published Apple Silicon results say only "M4 Max, 128GB" and never state the GPU core count. That omission does not have to block anything, because Apple offers 128GB on ONE bin only -- its Mac Studio specs read "48GB, 64GB, or 128GB unified memory (M4 Max with 16-core CPU and 40-core GPU)". So a 128GB M4 Max is necessarily the 40-core part at 546 GB/s, and the 32-core bin tops out at 36GB. Sold in both the Mac Studio and the 16-inch MacBook Pro; the form factor is recorded as desktop because the Studio is the configuration these runs usually come from, and nothing in this dataset distinguishes the two thermally. No price: 128GB is a build-to-order upgrade rather than one of the standard tiles Apple's buy page renders, so no figure could be tied to this configuration at the source.
