Apple Silicon Mac Pro might use two M1 Ultra CPUs for speed


In order to create a single 40-core SoC, it is possible that the Apple Silicon Mac Pro will follow the Mac Studio’s M1 Ultra’s path.

There were hints to an Apple-powered Mac Pro during the company’s “Peek Performance” presentation, opening the door to conjecture about what’s to come. Apple is said to be going one step farther than it did with the Mac Studio when it comes to using its current CPUs.

A die-to-die connector dubbed UltraFusion was created for the Mac Studio to link two M1 Max processors together. The idea is to use two chips to create a single, powerful version with 20 CPU cores, a 64-core GPU, and 32 cores for the Neural Engine to process information.


An picture leaked by “Majin Bu” on Twitter purports to show a design for an interconnect that would link “2 M1 Ultra together,” expanding the idea by another level. An anonymous leaker claims that “Redfern” processors will be featured in the upcoming 2022 Mac Pro, which is expected to be released in September of this year.

For a four-chip assembly to be right, the two M1 Ultra assemblies must be placed side-by-side on a new bridge. For the four M1 Max chips, three interconnects would be utilised in total, including two for the M1 Ultra chips.

There are, however, several drawbacks to the connector depicted here. As of now, the Mac Studio can only handle 128GB of RAM due to an outdated bridging technology.


Earlier speculations suggested that a Mac Pro with this many cores would be coming. As recently as May 2021, there were rumours circulating that the Mac Pro will be equipped with CPUs with as many as 40 compute cores and as many as 64 or 128 cores of graphics processing.

Leaked information indicates that the Apple Silicon chip will have many more cores than the current Mac Pro. The 28-core Intel Xeon W processor is the highest-core-count option available in the current Intel version. However, the Apple Silicon Mac Pro’s maximum RAM is lower than the Intel Mac Pro’s.
