Apple M3 Chip Configurations Purportedly Leaked

Chip configurations for the Apple M3, M3 Pro, M3 Max, and M3 Ultra chips have purportedly been leaked by Bloomberg's Mark Gurman.

In a weekly newsletter, Gurman offers a breakdown of each chip, including the number of CPU and graphics cores.

The M3 chip is said to have 8 CPU cores (4 performance and 4 efficiency) and 10 GPU cores. The chip will likely be used for the 13-inch and 15-inch MacBook Air, 13-inch MacBook Pro, iMac, iPad Pro, and Mac mini.


The M3 Pro chip is expected to have 12 CPU cores (6 performance and 6 efficiency) and 18 GPU cores. A higher-end configuration may have 14 CPU cores (8 performance and 6 efficiency) and 20 GPU cores. It chip will likely be used for the 14-inch MacBook Pro, 16-inch MacBook Pro, and Mac mini.

The M3 Max chip has 16 CPU cores (12 performance and 4 efficiency) and 32 GPU cores. The top-end configuration adds an additional 8 GPU cores for a total of 40. It will likely be used for the 14-inch MacBook Pro, 16-inch MacBook Pro and Mac Studio.

Finally, the M3 Ultra chip will have a base configuration with 32 CPU cores (24 performance and 8 efficiency) and 64 GPU cores. The top-end configuration will add an additional 16 GPU cores for a total of 80. It will likely be used for the Mac Studio and Mac Pro.

Notably, there are new MacBook Pro devices in testing with 36GB and 48GB of RAM, suggesting more configuration options may be available to customers rather than just 16, 32, 64, and 96GB.


Gurman does not expect Apple to release M3 Pro and M3 Max computers until next year and he suggests the M3 Ultra might arrive at the end of 2024 at the earliest. Please download the iClarified app or follow iClarified on Twitter, Facebook, YouTube, and RSS for more Mac updates.
