Apple is adding “one last chip” to the M1 processor family: the M1 Ultra is a new design that uses “UltraFusion” technology to strap two M1 Max chips together, resulting in a huge processor that offer 16 high-performance CPU cores, 4 efficiency cores, a 64-core integrated GPU, and support for up to 128GB of RAM.
It looks a whole lot like Apple is using a chiplet-based design for the M1 Ultra, just like AMD is doing for many of its Ryzen chips. A chiplet-based approach, as we’ve written, using multiple silicon dies to make larger chips can result in better yields, since you don’t need to throw a whole monolithic 20-core chip out if a couple of cores have defects that keep them from working.
Like the other M1 chips, the M1 Ultra is manufactured on a 5nm TSMC manufacturing process. If you want to know the chip’s other key specs, simply double everything Apple is doing in the M1 Max—that means up to 800GB/s of memory bandwidth, and a 32-core Neural Engine.
