Apple’s upcoming Mac Pro is not only reported to receive a design change, the product represents the company’s transition to its custom chipsets for all machines that feature Intel processors. As for the SoC that will be a part of the workstation’s internal specifications, one tipster believes that it will be an extension of the M1 Max cores. Given its size, the Mac Pro could easily accommodate several chip dies and cool them effectively.

As much as we would have liked to see the Mac Pro touting a variation of the M2 chipset, which would have resulted in improved performance and power efficiency, Dylan believes the SoC will be an extension of the M1 Max. For those that do not know, the M1 Max is Apple’s most powerful custom silicon to date and is featured in the redesigned 2021 MacBook Pro family. However, we are confident that there is something more powerful across the horizon, and we just need to exercise a little patience to see it in action later this year.
