Now packed with 20 billion transistors, the Apple M2 integrates the CPU, GPU, Neural Engine, I/O, and more into a single system on a chip (SoC). The additional transistors, 25 percent more than the M1, improve the features of the chip, including the memory controller that can deliver up to 100 GB/s of unified memory bandwidth. The M2 has faster performance cores with a larger cache and the efficiency cores have been enhanced for more performance gains. Together, the M2 delivers up to 18 percent greater multithreaded performance than the M1. This means the Apple M2 performs up to 1.4 times faster than the previous generation M1 while still delivering battery life of up to 15 hours of wireless web browsing and up to 18 hours of video playback.
