What is the Apple M1?

The M1 is an APU from Apple on the Apple M1 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. M1 full specifications →

Can I rent the M1 in the cloud?

Flopper is not tracking any live rental listings for the M1 yet. The provider directory lists the clouds that rent comparable accelerators on demand. GPU cloud providers →

How does the M1 compare with other accelerators?

This page sets the M1 against the M1 Ultra. The M1 is the older generation of the two. 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 M1 figures come from?

Apple published the M1 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

The M1 Ultra is the newer part: Apple M1 (2022) against the M1's Apple M1 (2020).

The M1 Ultra carries 112 GB more memory (128 GB against 16 GB), so larger models fit on one GPU before you shard. Bandwidth is 67 GB/s against 800 GB/s, which sets the ceiling on decode speed.

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