Apple’s first Mac chipset is now a reality – meet the Apple M1. The company claimed many superlatives including the world’s fastest CPU core, fastest integrated GPU and massive gains in energy efficiency. The M1 is a massive 5nm chip with a whopping 16 billion transistors. For comparison, the iPhone’s A14 chipset has 11.8 billion transistors, so this is beefed up noticeably. This chip is still similar to mobile chips (and console APUs) in that it has a unified memory architecture – this means that the same memory is accessible by the CPU, GPU, I/O controller and other components...
