The Apple M1 Pro is an ARM-based system on a chip (SoC) designed by Apple. Developed for the Mac line of computers, the M1 Pro and the larger M1 Max were introduced by Apple during a special event on October 18, 2021 for the 14 and 16-inch MacBook Pros.[1]

Specifications

The M1 Pro is manufactured by TSMC to Apple's design specifications. The 245 mm2 die contains 33.7 billion transistors that are fabricated through a 5 nm process. Dynamic RAM (DRAM) is built onto the package and is shared with memory bandwidth of up to 200GB/s through Apple's unified memory architecture (UMA) to eliminate the need to copy data from the CPU to GPU, which are both part of the package.[2][3]

The 10-core CPU (same as in the M1 Max) contains eight high-performance cores and two high-efficiency cores, similiar to the ARM big.LITTLE architecture used by mobile devices for power efficiency. The GPU contains 16 cores for graphics. However, in some entry-level configurations, two of the high-performance cores and two of the GPU cores are deactivated, indicating the practice of binning.[4] The Neural Engine contains 16 cores for machine learning performance. The Media Engine accelerates codec processing at low power with added support for ProRes. A Thunderbolt 4 and USB4 controller is included on the chip. It also includes its own Secure Enclave.[2]

Performance and compatibility

Apple advertises up to 70% faster CPU performance than the preceding M1 and double the GPU performance.[2] Compatibility with Intel software is provided through Rosetta 2 emulation, with a reported performance hit of about 21-22%, but still exceeding the speed of Apple's Intel-based models.[5][6] The first operating system from Apple to support the M1 Pro and M1 Max is macOS Monterey, which can also natively run iPadOS applications on the M1 processor family.[2]

Limitations

DRAM must be ordered in advance in 16 or 32 GB configurations as they are part of the M1 Pro's SoC package.[2][4]
