Apple M2 is a series ofARM-basedsystem on a chip (SoC) designed byApple, launched 2022 to 2023. It is part of theApple silicon series, as acentral processing unit (CPU) andgraphics processing unit (GPU) for itsMacdesktops andnotebooks, theiPad Pro andiPad Airtablets, and theVision Promixed reality headset. It is the second generation of ARM architecture intended for Apple's Mac computers afterswitching from Intel Core to Apple silicon, succeeding theM1. Apple announced the M2 on June 6, 2022, atWorldwide Developers Conference (WWDC), along with models of the MacBook Air and the 13-inch MacBook Pro using the M2. The M2 is made withTSMC's "Enhanced5-nanometer technology" N5P process and contains 20 billion transistors, a 25% increase from the M1. Apple claims CPU improvements up to 18% and GPU improvements up to 35% compared to the M1.^{[‡ 1]}

The M2 was followed by the professional-focusedM2 Pro andM2 Max chips in January 2023. The M2 Max is a higher-powered version of the M2 Pro, with moreGPU cores andmemory bandwidth, and a largerdie size.^{[‡ 2]} In June 2023, Apple introduced theM2 Ultra, a desktopworkstation chip containing two M2 Max units.^{[‡ 3]} Its successor,Apple M3, was announced on October 30, 2023.

The M2 has four high-performance @3.49 GHz "Avalanche" and four energy-efficient @2.42 GHz "Blizzard"cores, first seen in theA15 Bionic, providing ahybrid configuration similar toARM DynamIQ, as well as Intel'sAlder Lake andRaptor Lake processors. The high-performance cores have 192 KB of L1instruction cache and 128 KB of L1 data cache and share a 16 MB L2 cache;^[4] the energy-efficient cores have a 128 KB L1 instruction cache, 64 KB L1 data cache, and a shared 4 MB L2 cache. It also has an 8 MB system level cache shared by the GPU.

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.^[5]

The M2 integrates an Apple designed ten-core (eight in some base models, nine in the M2 iPad Air)graphics processing unit (GPU). Each GPU core is split into 16execution units, which each contain eightarithmetic logic units (ALUs). In total, the M2 GPU contains up to 160 execution units or 1280 ALUs, which have a maximum floating point (FP32) performance of 3.6TFLOPs.

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.

The M2 uses 6,400MT/sLPDDR5 SDRAM in aunified memory configuration shared by all the components of the processor. The SoC and RAM chips are mounted together in asystem-in-a-package design. 8 GB, 16 GB and 24 GB configurations are available. It has a 128-bit memory bus with100 GB/s bandwidth, and the M2 Pro, M2 Max, and M2 Ultra have approximately200 GB/s,400 GB/s, and800 GB/s respectively.^{[‡ 4]}

The M2 contains dedicatedneural network hardware in a 16-core Neural Engine capable of executing 15.8 trillion operations per second. Other components include animage signal processor, aNVM Express storage controller, aSecure Enclave, and aUSB4 controller that includesThunderbolt 3 (Thunderbolt 4 on Mac mini) support. The M2 Pro, Max and Ultra support Thunderbolt 4.

Supportedcodecs on the M2 include 8KH.264, 8KH.265 (8/10bit, up to 4:4:4), 8KApple ProRes,VP9, andJPEG.
