Announced last Tuesday, the processor
M1 Ultra installed on board the new mac studio
combines two M1 Max chips thanks to the “UltraFusion” bridge, a new interconnect technology that allows two APUs to become one. Rumors now suggest that Apple would use the same principle to form a huge SoC consisting of two M1 Ultra chips. It would be dedicated to the next Mac Pro.
As we know, the next Mac Pro will bet for the first time on an ARM Apple silicon chip. Still powered by Intel Xeon processors in its current form, Apple’s desktop computer would go big by betting on a huge chip made up of two M1 Ultra processors, combined with each other. This is in any case what advances the leaker Majin Bu on Twitter.
A very (very) large processor for the new Mac Pro?
The interested party shared a photo of a plan revealing an interconnect technology which this time would be intended to juxtapose two M1 Ultra chips. The idea would be to create an XXL chip made up of a total of four M1 Max chips. The latter would currently be codenamed “Redfern” after Majin Bu. And still according to his information, the Mac Pro could benefit from it as early as September.
As pointed out WCCFTech, this new processor could thus accumulate, if confirmed, no less than 40 CPU cores and 128 GPU cores (the M1 Ultra chip alone has 20 CPU cores and 64 GPU cores). What to put the chip in the ear: a few weeks ago, Mark Gurman, journalist for Bloomberg often well-informed, correctly predicted that the next-generation Mac Pro would benefit from a chip with this exact configuration.
Mac Pro’s Intel Xeon processors soon to be buried
Beyond this impressive core count, this new chip could have a maximum of 256 GB of unified RAM (compared to 128 GB on the Apple M1 Ultra) for a memory bandwidth possibly reaching 1.6 TB / s.
For this, however, this new processor would have to combine two M1 Ultra chips in full. If so, there could also be a total of 288 billion transistors spread over a die 16 times larger than that of the “classic” M1 chip. Of course, this information is still worth taking with a grain of salt, at least until it’s a bit more substantiated.
