Apple M2 is a series of
The M2 was followed by the professional-focused M2 Pro and M2 Max chips in January 2023. The M2 Max is a higher-powered version of the M2 Pro, with more
Design
CPU
The M2 has four high-performance @3.49 GHz "Avalanche" and four energy-efficient @2.42 GHz "Blizzard"
The M2 Pro has 8 performance cores and 4 efficiency cores in the unbinned model, or 6 performance cores and 4 efficiency cores in the binned model. The M2 Max has 8 performance cores and 4 efficiency cores in both the binned and unbinned SKUs, and operates at a slightly higher 3.7GHz clock speed in some models.[7]
GPU
The M2 integrates an Apple designed ten-core (eight in some base models)
The M2 Pro integrates a 19-core (16 in some base models) GPU, while the M2 Max integrates a 38-core (30 in some base models) GPU. In total, the M2 Max GPU contains up to 608 execution units or 4864 ALUs, which have a maximum floating point (FP32) performance of 13.6 TFLOPS.
The M2 Ultra features a 60- or 76-core GPU with up to 9728 ALUs and 27.2 TFLOPS of FP32 performance.
Memory
The M2 uses 6,400 MT/s LPDDR5 SDRAM in a unified memory configuration shared by all the components of the processor. The SoC and RAM chips are mounted together in a system-in-a-package design. 8 GB, 16 GB and 24 GB configurations are available. It has a 128-bit memory bus with 100 GB/s bandwidth, and the M2 Pro, M2 Max, and M2 Ultra have approximately 200 GB/s, 400 GB/s, and 800 GB/s respectively.[8]
Other features
The M2 contains dedicated
Supported codecs on the M2 include 8K H.264, 8K H.265 (8/10bit, up to 4:4:4), 8K Apple ProRes, VP9, and JPEG.
