Apple M1 Max chips could be stacked to create a monster 40-core processor

New images of Apple’s latest silicon appear to hint at the possibility of connecting multiple M1 Max chips together to create an extremely powerful Multi-Chip Module (MCM), which would be perfect for a Mac workstation.

As Noted By YouTuber Vadim Yuryev, the underside of the M1 Max houses a matrix-to-matrix interconnect that was not featured in any of Apple’s official marketing materials at launch.

In theory, this interconnect bus could allow two or even four chip M1 Max configurations, multiplying the already hugely impressive performance offered with Apple’s most powerful silicon.

The “M1 Max Quadra”?

In October, Apple released two new high-performance chips: the M1 Pro and the M1 Max. This latest system on a chip (SoC) has an incredible 57 billion transistors, a ten-core processor CPU and 32 hearts GPU, memory bandwidth of 400 Gb / s and up to 64 Gb RAM.

Already, video montage professionals and others whose work requires a mobile workstation report massive performance improvements with the M1 Pro and Max, over the previous one Macbook Pro generation.

For context, an M1 Max-powered MacBook Pro was recently found for outperform a Mac Pro equipped with a $ 6,000 GPU for graphics workloads, while consuming considerably less power.

However, the ability to chain multiple M1 Max chips (note the M1 Pro does not feature an interconnect) into one chip design could unlock even further performance scaling.

A four M1 Max setup tied to Mac Pro, for example, would offer 40 CPU cores and 128 GPU cores, theoretically to quadruple performance. Apple would need to recruit an I / O chip or fabric interconnect to make such a design possible, however.

Apple has so far been silent on its M1 Max hidden interconnect plans. TechRadar Pro asked the company for comment, but did not receive an immediate response.
