Apple M1 Ultra combines two M1 Max chips together

Apple adds “final chip”to M1 processor family. The M1 Ultra is a new design that uses “UltraFusion”technology to fuse two M1 Max chips together, resulting in a huge processor with 16 high-performance CPU cores, four efficient cores, a 64-core integrated GPU, and support for up to 128GB random access memory.

It’s entirely possible that Apple is taking a chiplet approach to the M1 Ultra, something along the lines of what AMD does for many of its Ryzen chips. The chiplet-based approach, as we’ve already written, uses multiple silicon dies to make larger chips and can result in higher yields because you don’t have to throw away an entire monolithic 20-core chip if a couple of cores have defects that interfere with them. work.

Like other M1 chips, the M1 Ultra is manufactured using TSMC’s 5nm process. If you want to know the other key specs of the chip, just double everything Apple does in the M1 Max – that means up to 800GB/s of memory bandwidth and a 32-core neural engine.

The M1 Ultra will run Apple’s just-announced Mac Studio in a more expensive $3,999 configuration that also includes 64GB of RAM and a 1TB SSD. We have more details about the studio in a separate post.
