Rumor mill: Apple is working on an M1 Max Duo SoC for the next iMac Pro

It’s no big industry secret that Apple is working feverishly behind the scenes to remove all traces of Intel silicon from its Mac lineup. The company announced plans to switch from Intel to its own custom chips several years ago, and in 2020 it began the replacement process with the original M1 chip landing at the very bottom of its range with the MacBook. Air, the Mac Mini and the entry level. iMac level 24 ″. Then the upgraded M1 Pro and Max SoCs, which landed in the company’s revamped 2021 MacBook Pros. So there are only two models left on the upgrade path: the “big” 27-inch iMac and the pinnacle of power, the Mac Pro, which still use Intel processors and AMD discrete GPUs. According to a report, one of these chips will soon break; an M1 Max Duo SoC, the company plans to integrate a brand new iMac Pro.

As the name suggests, the M1 Max Duo would be made up of two M1 Max chips connected together to double whatever the Max chip offers. This translates into a 20-core processor and a 64-core GPU, as well as the ability to have up to 128 GB of RAM. There are also Mac Pro rumors suggesting an M1 Max Quadro, with a 4x design. This is a huge upgrade from the original M1 chip, which only has eight processor cores and seven GPU cores, as well as a maximum of 16GB of memory. The sources of these rumors are twofold: Bloomberg reporter Mark Gurman, and Hector Martin, who brings Linux to Apple’s silicon Macs.

Starting with Gurman, who is a well-known Apple insider, he pointed out in a recent tweet that Apple is indeed working on taking the M1 Max dice and simply multiplying it both 2x and 4x for future desktop chips. In his tweet he writes: “… the new Mac Pro desktop should come in at least two variants: 2X and 4X the number of CPU and GPU cores than the M1 Max. That’s up to 40 CPU cores and 128 GPU cores on the high end. This accords with information from Mr. Martin, who has been neck and neck in the MacOS code and reports, “… macOS drivers have a lot of multi-die references, and the IRQ controller in the M1 Pro / Max is very clearly designed with a second half (currently unused) for a second die.” If that’s not enough information from you, he adds: “For technicians: this is a second set of config / mask / software-gen / hw-state registers, and the hardware entries are all inactive but you can generate software IRQs in this block just fine and they come with a die-id of 1 in the first 8 bits of the event register. If you’re more into the video, YouTuber MaxTech goes into the details of all these rumors.

For those of us who are silicon enthusiasts, it has been fascinating watching Apple’s moves in this market, as the M1 chips have shaken up the notion of what we can expect from a mobile processor by offering both breathtaking performance and incredible efficiency; a rare feat indeed. This is why Apple’s prospect of providing a chip that doesn’t need to be integrated into a mobile device is appealing, as they can theoretically run wild dogs as they won’t have to worry about consuming dots. energy, at least within reasonable limits. The bad news, however, is that the same informants who come up with these tantalizing leaks are also quoting insane prices for so much power, with one pointing out that the top-end Mac Pro could cost. about $ 50,000. That shouldn’t be such a big surprise though, as you can already spend that much money quite easily on the current Xeon-powered Mac Pro tower even without the $ 400 wheels.
