Based on the Apple M1, the M1 Pro and M1 Max are Apple's first professional-focused systems-on-a-chip. The M1 Max is a higher-powered version of the M1 Pro, with more GPU cores and memory bandwidth and a larger die size.[3]

Design

CPU

The M1 Pro and M1 Max have eight high-performance "Firestorm" (six in lower-binned variants of the M1 Pro) and two energy-efficient "Icestorm" cores, providing a hybrid configuration for a total of 10 cores (8 in some base models of the M1 Pro).[1]

GPU

The M1 Pro integrates an Apple-designed 16-core (14 in some base models) graphics processing unit (GPU), while the M1 Max integrates a 32-core (24 in some base models) GPU. Each GPU core is split into 16 Execution Units, which each contain eight Arithmetic Logic Units (ALUs). In total, the M1 Max GPU contains up to 512 Execution units or 4096 ALUs, which have a maximum floating point (FP32) performance of 10.4 TFLOPs.

They have the same 16-core Neural Engine, Secure Enclave, and two media engines as the Apple A14 Bionic, and include three Thunderbolt 4 controllers.[4] The M1 Pro includes a media engine supporting ProRes encoding and decoding, while the M1 Max includes two engines.[5]

Other features

The M1 Pro and M1 Max have a unified memory architecture, meaning that all components on the chip, such as the CPU and GPU, share the same memory addressing. The memory is LPDDR5-6400 SDRAM on 8 channels with a total bandwidth of 200 GB/s for the M1 Pro and 400 GB/s for the M1 Max. The M1 Pro comes in memory configurations of 16 GB and 32 GB, while the M1 Max comes in configurations of 32 GB and 64 GB.[6] The M1 Max supports High Power Mode on the 16-inch MacBook Pro for intensive tasks.[7] The M1 Pro supports two 6K displays over Thunderbolt and a 4K monitor over HDMI, while the M1 Max supports a third 6K display over Thunderbolt.[8]
