Apple’s announcements of the Mac Studio, the Studio Display, in addition to the new top-end M1 Ultra chip earlier this week focused on those devices’ headlining features, but there are always more details to explore as people dig through the spec sheets and even Apple responds to questions from the press. Ahead of our full reviews, we’ve compiled some of the most interesting information about the new hardware.

M1 Ultra: One big piece of silicon

When the M1 Ultra was announced, we speculated based on how Apple was describing it that the processor was using a chiplet-based design, connecting two separate M1 Max processor dies together using a high-speed interconnect like AMD’s Infinity Fabric. That turns out not to be true—the M1 Super is apparently one big bit of silicon, just as it appears in Apple’s render shots.

The main risk with creating such the huge chip is that manufacturing yields will be low, as more surface area increases the likelihood that there will be a new defect somewhere in the chip. But TSMC has been making M1-based chips on its 5 nm process for well over a year now, giving it plenty associated with time to optimize yields. And Apple is able to do some binning with the M1 Extremely (i. e., selling some chips with defects as lower-end models with the defective parts turned off) since there are versions with both 48 and 64 GPU cores.
