The Apple Silicon Mac Pro may follow the lead of the Mac Studio's M1 Ultra, a rumor claims, by effectively combining two M1 Ultra chips into a single 40-core SoC.
Apple's "Peek Performance" event included a brief tease for a Mac Pro using Apple Silicon, opening the door to speculation about the inbound update. In one rumor, it is said that Apple will go one stage further than it did with the Mac Studio in reusing its existing chips in new ways.
For the Mac Studio, Apple introduced the M1 Ultra, a chip that connected together two M1 Max chips with a die-to-die interconnect called UltraFusion. The concept effectively makes two chips work as one singular powerful version, complete with 20 CPU cores, a 64-core GPU, and 32 Neural Engine cores.
An image leak by "Majin Bu" on Twitter claims to show a schematic for an interconnect that will connect "2 M1 Ultra together," extending the concept by another level. The leaker says the bridge will be "found in the new 2022 Mac Pro," with a processor name of "Redfern," and is scheduled for a September release.
If the image is correct, the supposed four-chip assembly will practically introduce a new long bridge that sits the two M1 Ultra assemblies side by side. Three interconnects would be used in total to connect the four M1 Max chips, including the two used to form a pair of M1 Ultra chips.
However, the interconnect as shown would have some limitations. Without a newer bridging technology, RAM would be limited to the same 128GB as the Mac Studio supports.
The idea of a Mac Pro with such a high number of cores has been presented in earlier rumors. In May 2021, there were claims the Mac Pro could use chips with 20 or 40 computing cores, and graphics options with either 64 or 128 cores.
If the leak is genuine, the proposed Apple Silicon chip will offer considerably more cores than the existing Mac Pro offers. Under the existing Intel version, the maximum amount of cores is offered by a 28-core Intel Xeon W processor. But, maximum RAM would be less on the Apple Silicon Mac Pro versus the Intel Mac Pro.

Except…
John Turnes of Apple quite literally said that the M1 Ultra completes the M1 line up just days ago
It is more likely that the MacPro will be based on M2 silicon or even a completely different designStuart
If Mac Pro makes it before M2 Gen, then I’d say this is pretty much what we expect. M1 Ultra x1, x2, x4, x6, and x8. Major power. Hefty price tag. And possibly 2nd Gen ProDisplay XDR launches with it.
And, fingers crossed, some expandability.
We shall see…
I’m waiting for a video meme where you see a super-long chip, which just goes on and on for a minute until it is presented as the ”Apple M1 200X Ultra” or something.
I'm surprised TSMC can keep a new headlining chip for Apple a secret.
