Apple Announces Second-Generation Custom Silicon Chip for the Mac

This month, Apple introduced the M2 chip – the second-generation custom silicon chip for the Mac. After the M1 chip revolutionized the Mac starting in November 2020, how much better really is the M2? The ‌M1‌ and ‌M2‌ both have four high-performance and four energy-efficient cores, but while the ‌M1‌ features "Firestorm" and "Icestorm" cores from the A14 Bionic chip, the ‌M2‌ offers "Avalanche" and "Blizzard" from the A15 Bionic chip. Overall, the ‌M2‌ chip offers moderate improvements over the ‌M1‌, even if most ‌M1‌ users are unlikely to notice significant improvements when upgrading to the ‌M2‌. Apple says that the ‌M2‌ chip takes the performance per watt of the ‌M1‌ even further with an 18 percent faster CPU, a 35 percent more powerful GPU, and a 40 percent faster Neural Engine. The ‌M2‌ chip debuts in the 13-inch MacBook Pro and the redesigned MacBook Air, so the extent to which the ‌M2‌ is better than its predecessor could be an important consideration when purchasing a new Mac. Like the A14 Bionic, the ‌M1‌ chip is built using TSMC's first-generation 5nm fabrication process. On the other hand, the ‌M2‌ uses TSMC's second-generation 5nm process like the A15 Bionic chip.
