What is the Apple M3 Max?

The M3 Max is an APU from Apple on the Apple M3 architecture, an processor that pairs CPU and GPU on one chip. It is a system-on-chip, so it is built into edge and embedded devices rather than sold as a card. M3 Max full specifications →

Can I rent the M3 Max in the cloud?

Flopper is not tracking any live rental listings for the M3 Max yet. The provider directory lists the clouds that rent comparable accelerators on demand. GPU cloud providers →

How does the M3 Max compare with other accelerators?

This page sets the M3 Max against the M3 Pro. Both parts launched in the same year. Both are Apple parts, and both ship as a system-on-chip, so they fit the same class of system. The compare tool builds the same comparison for any two parts in the catalogue. All GPU comparisons →

Where do the M3 Max figures come from?

Apple published the M3 Max figures in marketing material rather than a datasheet, and Flopper has no independent confirmation of them. How Flopper verifies specifications →

Figures are dense. Where a vendor publishes a figure it sits under the dense one and never decides a winner. Hover any precision for its definition, or read the GPU glossary.

FLOPS by Precision

What actually differs

Both launched in 2023, the M3 Max on Apple M3 and the M3 Pro on Apple M3.

The M3 Max carries 92 GB more memory (128 GB against 36 GB), so larger models fit on one GPU before you shard. Bandwidth is 400 GB/s against 150 GB/s, which sets the ceiling on decode speed.

Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
