M2 will power redesigned MacBook Air The new MacBook Air does away with the laptops signature tapered teardrop shape introduced with the first generation back in 2008. The dedicated Apple ProRes hardware encoders found on the M1 Pro, M1 Max, and M1 Ultra make an appearance on the M2, which additionally supports hardware encoding and decoding of H264 and H265, supporting resolutions up to 8k. (Apple Silicon machines share memory rather than having dedicated RAM for the system and separate RAM for the graphics processor.) Plus, maximum system memory has been increased from 16GB to 24GB.
The addition of these two extra cores improves graphics performance by as much as 35%. The M2 has 25% more transistors and supports two more GPU cores than the M1. The M2 chip next to the previous generation M1. Apple says the increase in transistors boosts performance across the whole chip, including allowing the memory controller to deliver a 50 percent increase in unified memory bandwidth at 100 GB/s. The M2 is built on a 5nm dye, similar to the M1 and consists of 20 billion transistors-that’s 25 percent more than what was found on the M1. The new M2 platform brings a host of improvements that build on the architecture of the M1, including an 18% faster CPU. Even with the full lineup transition from Intel to Apple Silicon not quite complete, Apple announced the second generation of its in-house M-Series chips at WWDC this week.
