Apple reportedly engaged on M1 Max Duo chip for subsequent technology Mac Professional


Rumor mill: Apple’s newest silicon, the M1 Professional and M1 Max, have barely come off MacBook Professional meeting traces, and rumors are already circulating about what’s subsequent for Apple silicon. Somewhat than going again to the drafting board and designing chips with even increased specs, why not simply knit two Max SoCs collectively?

As you’re most likely conscious, Apple vowed to fully ween itself off of Intel elements by the tip of subsequent yr. To date, it’s proper on monitor. The MacBook Air, 13-inch Macbook Professional, Mac mini, and the 24-inch iMac are already sporting M1 silicon, and Apple simply unveiled the redesigned 14- and 16-inch MacBook Execs with their next-generation M1 Professional and M1 Max chips. That solely leaves the 27-inch iMac and the Mac Professional workstations nonetheless on the Intel nipple. Absolutely this can change subsequent yr.

Famous Apple leaker Mark Gruman says Apple plans to energy the Mac Professional with twin M1 Max SoCs (M1 Max Duo) on the bottom fashions and 4 (M1 Max Quadro) on high-end models. That is a minimal of 20 compute cores and 64 graphic cores with as much as 128GB of RAM and double all that for the Quadro.

Hector Martin, who’s within the strategy of porting Linux to M1 Professional/Max Macs, not directly backs up Gruman’s claims with proof he discovered in macOS.

“The macOS drivers have loads of multi-die references, and the IRQ controller within the M1 Professional/Max could be very clearly engineered with a (at present unused) second half for a second die,” tweeted Martin. “For the technically minded: it is a second set of config/masks/software-gen/hw-state registers, and the {hardware} inputs are all idle however you may software-gen IRQs in that block simply wonderful and so they get delivered with a die-id of 1 within the high 8 bits of the occasion register.”

So far as price, hypothesis is that high configurations will run an eye-watering $50,000 or extra, however that’s not shocking since patrons can configure the present Intel-based Mac Professional to price almost $55,000. That stated, low-end models ought to begin throughout the $6,000-$6500 value vary.

Gruman solely spoke of the Mac Professional receiving the Duo and Quadro silicon, in order that simply leaves the 27-inch iMac sporting Intel chips. Nevertheless, Max Tech host Vadim Yuryev says there may be sturdy proof that Apple will use an M1 Max Duo within the bigger iMac variant (video above). He factors out that merely utilizing a single M1 Max can be a downgrade from present Intel-based iMacs.

Designing a complete new chip is a risk. Rumors are already circulating {that a} 40-core M2 chip is on monitor for 2023, however that falls past Apple’s deadline for ditching Intel. Yuryev is satisfied that it’s going to most likely use binned and unbinned M1 Max Duos for prosumer {and professional} configurations, respectively, relatively than a complete new die. He suspects Apple to disclose the following iMacs as early as March of subsequent yr. Once more, this falls in inline with Cupertino’s roadmap for silicon independence with out sidelining the M2 predictions.
