WCCF Tech came across a rumor about a future variant with 64 cores. This model is most likely reserved for the most powerful Mac desktop computers.
The new 64-core Apple Silicon may be provided alongside the new 32-core Mac Pro, with the company stamping a premium for the more powerful product. Then again, looking at the capabilities of the M1, a 32-core-fueled Mac Pro should be more than sufficient to handle anything in its path, so it’s not clear who the 64-core model will be targeted to, assuming Apple is actually working on something like this.
