The Apple M1 Ultra is an ARM-based system on a chip (SoC) designed by Apple. Developed for the Mac line of computers, the M1 Ultra was introduced by Apple during a special event on March 8, 2022.[1]

Features

The M1 Ultra features twice the capabilities of the Apple M1 Max with 20 CPU cores, including 16 high-performance units and 4 high-efficiency units. It also features 32 Neural Engine cores capable of up to 22 trillion operations per second. The M1 Ultra also contains two Thunderbolt 4 / USB4 controllers which can support twice as many ports as the M1 Max. The M1 Ultra is available in two versions, with 48 or 64 GPU cores.[1]

The first computer to offer the Apple M1 Ultra as an option is the Mac Studio.[2]

Limitations

DRAM must be ordered in advance in 64 or 128 GB configurations as they are part of the M1 Ultra's SoC package. This also applies to the storage as the 1, 2, 4, or 8 TB SSD are also part of the package.[2][3]

Development

On March 8, 2022, Apple senior VP of hardware technologies Johny Srouji revealed that the M1 Max included a previously undisclosed interconnect feature called UltraFusion, which allowed two of the dies to be packaged together to create the M1 Ultra, with twice the computing power.[1] The silicon interposer is stated to be able to handle over 10,000 low-latency signals for an interprocessor bandwidth of 2.5 TB per second.[2] The combined total die size is estimated to be 840 mm2.[4]
