The M3 Pro’s Specs Might Have Just Leaked Months Ahead Of Launch

Apple’s M3 series of Mac chips hasn’t yet launched but we might already know what the core configuration of the base M3 Pro will look like.

The M3 Pro is likely to power future 14 and 16-inch MacBook Pro models and Bloomberg’s Mark Gurman believes that they’ll likely arrive in 2024. However, it looks like Apple is already testing those chips in an unannounced MacBook Pro.

Gurman, writing via his Power On newsletter, says that a developer has already shared details of the Mac after it appeared in App Store logs.

The CPU, the chip’s main processor, is made up of six high-performance cores that handle the most intensive tasks and six efficiency cores that kick in for operations that need less power.

The chip is also thought to have 18 graphics cores and a maximum memory configuration of 36GB.

If these figures turn out to be accurate the M3 Pro will have two more CPU cores than the M2 Pro while also packing two additional graphics cores. The machine will also benefit from a higher RAM ceiling — the M3 Pro can support 36GB while the M2 Pro maxes out at 32GB.

Gurman says that the machine is running a version of macOS 14, a release that isn’t expected to be announced until WWDC23 in June before being made available for download in or around September or October.
