iMac Pro gets two M1 Max

iMac Pro gets two M1 Max

Points Highlighted:

  • The so-called M1 Max Duo would also have double the GPU performance (TFLOPs) of the M1X and its 32-core GPU. As Max Tech discusses below, the M1 Max is more powerful than the RX 5700 XT in the 27-inch iMac, but not by enough of a margin that could be considered a generational leap. Theoretically, offering double the GPU performance of the M1 Max would achieve this.

  • Supposedly, Apple will bolt two M1 Max dies onto one SoC, allowing it to offer 128 GB RAM support, currently a feature of the Intel-based 27-inch iMac.

Additionally, the M1 Max cannot compete with the CPU performance offered by the Core i7-10700K or the Core i9-10910. Hence, equipping a 27-inch iMac with the M1 Max would be a downgrade in terms of CPU and GPU performance. Offering a second M1 Max on the same chip could help Apple bridge that CPU gap, too.

Apple is expected to reveal a 27-inch iMac in Q1 2022 with a mini LED display. The PC is thought to offer a 120 Hz ‘ProMotion refresh rate, as well.

Incidentally, Hector Martin, who is porting Linux for Apple Silicon Macs, has discovered ‘plenty of multi-die references’ in macOS. Additionally, he states that Apple has designed the M1 Pro and M1 Max’s Interrupt request (IRQ) controllers with second halves for a second die. Currently, this second half is unused.
