The M1 Ultra is Apple’s fastest custom SoC to date and is being used in the Mac Studio. That is soon going to change as Apple is planning its successor already which is under development as we write this. That SoC is being designed and built for the more powerful Mac Pro.
When Apple presented the M1 Ultra, it declared that the most powerful chipset to come out of its doors was eight times the size of the M1 and was made by a combination of two M1 Max parts. This process has been given the name of UltraFusion by Apple itself. With the help of this new technique, Apple has been able to unlock new performance levels for the Mac Studio. Since the Mac Studio has been designed to be a stationary machine, it works at a higher voltage without draining the battery. This is because it doesn’t have to worry about the stress on the machines that come with portability.
A recent Bloomberg report suggests that the Mac Pro will be more powerful than the Mac Studio. It has been codenamed as J180 and will feature a chipset which will be the successor to the M1 Ultra. So far there has been no name given to this new chipset. This report published by Mark Gurman offers no further insight into the M1 Ultra successor. We are not sure how many cores it will be based on or what will Apple even call it.
