The Ultra is two processors and two chipsets tied together.Īnd that's likely to make it bigger and hotter. There are even two versions for both GPU variations of the M1 Max. That's why the Mac Studio with the M1 Ultra has more Thunderbolt ports and can accommodate twice the memory of its M1 Max-based counterpart. So it has two of everything, including two Thunderbolt controllers and two memory controllers. MacBook Pro 14, MacBook Pro 16 (2021), Mac StudioĪpple took a blunt approach for the M1 Ultra, tying together two M1 Max (24-GPU core) processors and chipsets via a 2.5 terabyte per second direct connection, branded "UltraFusion," rather than having to traverse the slower system bus. MacBook Air (2021), iPad Pro (5th gen), iMac 24 (2021), Mac Mini It's possible that some of the changes made for the M2, such as the higher-bandwidth memory controller, were necessary before the chip could be scaled up to Mac Pro-appropriate levels. We've still yet to see if linking together a large number of chips will work for the Mac Pro - the lone remaining Intel-based model. The progress from Pro to Max to Ultra shows how Apple scales its hybrid chip line to accommodate higher-power systems. The M1 line only scaled up to the M1 Ultra in March for the Mac Studio, so it's unsurprising that it may be a wait until the M2 switchover pervades all Apple's systems. We'll likely see the scaled-up versions - Ultra, Pro and Max - when Apple's ready to refresh its higher-end devices. As with the M1, Apple started at the bottom: The M2 is the base processor in the new line, with some typical generation-over-generation updates, and debuts in the 2022 MacBook Air and MacBook Pro 13-inch. Apple's M1 series of processors gained a new sibling, the M2, at WWDC 2022.
