The M2 chip is made with second-generation 5nm technology and has 20 billion transistors, which is 25% more than the M1 chip. In comparison to the M1 chip, the M2 has an 18% faster CPU, a 35% more powerful GPU, and a 40% faster Neural Engine.
The M2 has four performance and four efficiency cores and can support up to 24GB of LPDDR5 unified memory. The processor can handle 100GB/s of unified memory bandwidth, which is a 50% increase over the M1 chip.
Apple claims that the M2 is much faster than the competition at lower power use levels. The M2 chip features up to a 10-core GPU and two more cores than the M1 chip, delivering 18% more performance at the same wattage. The M2 achieves 87 percent of the peak performance of a 12-core PC laptop CPU while consuming only a quarter of the power.
M2 also includes a new image signal processor (ISP) that delivers better image noise reduction, as well as an improved media engine with a higher-bandwidth video decoder that supports 8K H.264 and HEVC video, a ProRes video engine to playback multiple streams of 4K and 8K video, Apple’s latest Secure Enclave for enhanced security, and a new image signal processor (ISP) that supports 8K H.264 and HEVC video.
The M2 chip is included in the latest MacBook Air and 13-inch MacBook Pro models.
