In June 2020, Apple revealed that its computing products were about to follow iPhones and iPads and use its own bespoke system-on-chip, the M1. Now the company has revealed its successor, and the first models to benefit from the marked performance boost.

The all-new M2 boasts second-generation 5-nanometer technology with some 20 billion transistors, representing a 25 percent increase over the M1. That's reported to result in 18 percent gains in multi-thread octa-core CPU performance while sipping less power, with Apple reckoning that the M2 is capable of delivering almost twice the performance of "the latest 10-core PC laptop chip" while drawing the same amount of power, or nearly 90 percent of the peak performance of a current-generation 12-core laptop chip at a quarter of the power. Users can also look forward to a 35 percent increase in graphics performance with the 10-core GPU option, which can also match the M1's peak performance while drawing only a fifth of the power. And there's a whopping 40 percent increase in the speed of the 16-core Neural Engine, which can now process up to 15.8 trillion operations per second.

The memory controller is reported to deliver a 50 percent improvement in unified memory bandwidth (100 GB/s) compared to its predecessor, with up to 24 GB of unified memory available. The media engine now supports 8K H.264 and HEVC video decoding, while the ProRes video engine caters for multiple streams of 4K and 8K video.
The MacBook Air will be available in four finishes from July for a starting price of US$1,199, the updated 13-inch MacBook Pro starts at $1,299.
