Mac Pro Apple Silicon: two M1 Ultra chips in a mega processor with 40 cores

The upcoming Apple Silicon Mac Pro could merge two M1 Ultra processors into a single mega chip with up to 40 CPU cores, 128 GPU cores, up to 256GB of RAM, and more.

To create its latest M1 Ultra chip for the new Mac Studio, Apple essentially bonded two M1 Max chips together using proprietary technology. UltraFusion. Reportedly, the company may be using the same technique to create a new chip for the Mac Pro by combining two M1 Ultra chips. Tentatively called “M1 Extreme”, the purported chipset would interconnect the die of four individual M1 Max chips to create a single chip with twice as many CPU and GPU cores as the M1 Ultra.

This would essentially create a Mac Pro chip with up to 40 processor cores, including 32 high-performance cores and 8 power-saving cores. The amount of RAM could double from the current 128GB limit on the M1 Ultra, hitting 256GB.

The current Intel-based Mac Pro (the only one left in the Mac lineup) comes standard with an eight-core Intel Xeon W processor and 32GB of RAM, but the machine can be configured with up to 28 cores. and 768 GB of DDR4 ECC memory.

If the rumors turn out to be correct, however, the Mac pro with Apple Silicon will feature the new M1 Extreme chip with the following specs:

  • CPU: 40 cores, 32 high-performance cores and 8 power-saving cores
  • GPU: 128 cores
  • RAM: 256 GB
  • Memory bandwidth: 1.6 TB/s
  • Neural engine: 64 cores

The most interesting aspect of this transition will be above all on the GPU side. The current Mac Pro can be configured with two Radeon Pro W6800X Duo cards with 64GB of GDDR6 memory each and additional Afterburner cards to speed up video operations. We’ll be very interested to know how the M1 Extreme compares to current Mac Pro GPUs.

We just have to wait for the next WWDC in June to find out what Apple has in store for us.
