Apple unveiled M2, the second generation of custom-designed ARM silicon chips, Monday at the company’s Worldwide Developers Conference (WWDC). These chips will power the new MacBook Air and 13-inch MacBook Pro.

“M2 kicks off the second-generation M-series chips and goes beyond the remarkable features of M1,” said Johny Srouji, Apple’s senior vice president of Hardware Technologies.

“With our relentless focus on power-efficient performance, M2 delivers a faster CPU, GPU and Neural Engine. And along with increased memory bandwidth and new capabilities like ProRes acceleration, M2 continues the tremendous pace of Apple silicon innovation for the Mac.”

The new chip, coming to M2, is built using improved second-generation 5 nanometer technology, comprising 20 billion transistors, which is 25 percent more than its predecessor, M1. It has a memory controller that delivers 100 GB/s of uniform memory bandwidth, providing 50 percent more memory bandwidth compared to the M1.

Furthermore, the M2 supports up to 24 GB of fast unified memory, allowing it to handle even larger and more complex workloads. It features four high-performance cores and four efficiency cores and has an 18% better performance than the M1.

According to Apple, the 8-core CPU in M2 offers almost twice the performance at the same power level compared to the latest 10-core PC laptop chip in a Windows laptop. In addition, M2 delivers nearly 90 percent of the peak performance of the latest 12-core PC laptop chip, while using only a quarter of the power.

The new chip also features Apple’s next-generation GPU with up to 10 cores, giving graphics performance up to 25 percent higher than the M1 at the same power level and up to 35 percent better performance at maximum power. The 10-core GPU in M2 delivers 2.3x faster performance at the same power level, matching its peak performance with a fifth of the power.

Plus, M2’s higher performance per watt means systems have exceptional battery life and run cool and quiet, even when playing graphics-intensive games or editing massive RAW images.

In addition to the above, the M2 also brings Apple’s latest custom technologies to the Mac which are as follows:

  • The Neural Engine can process up to 15.8 trillion operations per second – over 40 percent more than M1.
  • The media engine includes a higher bandwidth video decoder, which supports 8K H.264 and HEVC video.
  • Apple’s powerful ProRes video engine can play multiple streams of both 4K and 8K video.
  • Apple’s latest Secure Enclave offers best-in-class security.
  • A new image signal processor (ISP) provides better image noise suppression.

According to Apple, every chip Apple makes, from design to production, will be 100 percent carbon neutral. The new Apple M2 chip is expected to hit the market in July 2022.
