New Mac Pro gets extra powerful M1 chip
Mac Pro is currently the only Mac computer that has not been equipped with Apple’s own processor, but that will change within a few months.
According to technology leaker Dylan DKT, Apple is filing for new models of Mac Pro which will probably be launched in the autumn.
The new models will use a more powerful variant of the M1 Max chip, where the big news is more cores.
According to previous rumors, there are 20 processor cores and 64 graphics cores in the input model, while the top model offers 40 processor cores and 128 graphics cores. The code names for the two models are said to be Jade 2C-Die and Jade 4C-Die respectively.
There is also a rumor of a final model with Intel processor, something you can read more about below.
Update (2021-06-09):
Xcode can detect update
Mac Pro may be getting an update with new Intel processors, reports Appleinsider. In that case, it will most likely be the last new Mac to be released without Apple Silicon.
The rumor is based on a reference embedded in the new beta version of Xcode 13.1 that was released to developers after the WWDC opening. Brendan Shanks on Codeweavers discovered that Apple is referring to “Ice Lake SP” in a cpu-type file. SP means Xeon, and Mac Pro is the only Mac today with a Xeon processor.

There have been rumors in the past about an updated Mac Pro, and considering how far Apple seems to have a self-designed equivalent that can also handle pci express cards and copious amounts of internal memory, it might not be so strange if it happened.
