For Mac Studio, Apple introduced the M1 Ultra, a chip that linked two M1 Max chips with a die-to-die interconnect called UltraFusion. The concept makes two chips work as one powerful version, with 20 CPU cores, a 64-core GPU and 32 neural engine cores.
The “Peek Performance” event by Apple included a brief teaser of a Mac Pro use Apple Silicon, opening the door to speculation that these chips will be upgraded to a Pro model. In this rumor it is said that the Apple will go further than with Mac Studio by reusing your existing chips.

Based on what my resources are reporting, here’s some official info on the new 2022 Mac Pro
It is the bridge that connects 2 M1 Ultra to each other and that will be found in the new Mac Pro 2022.

A leak of information through an image in the Twitter, claims to show a schematic for an interconnect that will connect “2 M1 Ultra”, taking the concept to another level. The leaker specifies that this solution will be found “in the new Mac Pro 2022”, with a processor name “Redfern”, and that it is scheduled for a launch in September.
If the image is correct, the supposed four-chip set will practically introduce a new long connection that sits side-by-side with the two M1 Ultra sets. Three interconnects would be used in total to link the four chips M1 Maxincluding the two used to form a pair of chips M1 Ultra.
However, the interconnect as shown would have certain limitations. without new Technology connection, RAM would be limited to the same 128GB supported by Mac Studio.
The idea of a Mac Pro with such a high number of cores has been leaked in previous rumors. In May 2021, some claimed the Mac Pro could use chips with 20 or 40 compute cores and graphics options with 64 or 128 cores.
If the leak is real, the chip Apple Silicon offered will offer considerably more cores than existing Mac Pro offerings. According to the existing Intel version, the maximum number of cores is offered by a 28-core Intel Xeon W processor. But, the maximum RAM would be lower in the Apple Silicon Mac Pro compared to Intel Mac Pro.
