One Apple M1 Max and another M1 Max gave us the new M1 Ultra chip, which will be sold as part of the new Mac Studio.

On Tuesday, Apple added a chip monster to its Apple M1 lineup: the M1 Ultra, which mirrors some well-known chip design approaches and gives the PC market a high-end competitor to compete.
Essentially, the M1 Ultra combines two of Apple’s existing M1 Max chips into a single package. They are connected through a silicon interposer that Apple calls UltraFusion. result? A full 20-core ARM CPU with 16 performance cores and 4 efficiency cores. The M1 Ultra chip will debut in the Apple Mac Studio, a $3,999 (AU$6,099) workstation that Apple also announced on Tuesday.
Johnny Srouji, Apple’s senior vice president of hardware technology, noted that there are physical limitations to the design of future iterations of the M1 chip. By combining two M1 Max chips in a single package, Srouji said, Apple has created a high-performance system-on-chip.
So what does the M1 Ultra offer?
As Srouji points out, the M1 Ultra has a total of 20 cores, doubling the maximum CPU core count (and potential performance) on paper alone. Although 5nm process technology has been used on all previous chips, Apple did not specify what process technology the M1 Ultra uses. That could be a huge chip, since the M1 Max already has 57 billion transistors, and that would basically double. Apple is shown below:
Look at the size of things. The Apple M1 Ultra is huge – you can see the two M1 Max chips together inside the Ultra, with the UltraFusion interposer in between. Apple.
The two CPUs are connected via the new UltraFusion architecture, which provides a total bandwidth of 2.5 TB/s between the two chips, which Srouji says is four times the bandwidth of the leading multi-chip interconnect technology. The memory bandwidth is also increased to 800GB/s, and the total supported unified memory is 128GB.

Of course, connecting different silicon chips is nothing new. In fact, AMD announced its Ryzen Threadripper Pro 5000 chips on the same day. AMD’s explicit goal in developing Threadripper was to enable a large number of processor cores, a design that combines a variety of multi-core silicon chips. For example, the new 24-core Threadripper Pro 3945WX contains three 8-core CCDs (Core Chip Chips) that connect the cores together. (It’s worth noting that previous Threadrippers used a CCD with something called a CCX, or Core Complex, which connects the CPU chip to AMD’s Infinity Fabric – which is t
