Today, Apple has unveiled their brand-new MacBook line-up. This isn’t an ordinary release – if anything, the move that Apple is making today is something that hasn’t happened in 15 years: The start of a CPU architecture transition across their whole consumer Mac line-up.
Thanks to the company’s vertical integration across hardware and software, this is a monumental change that nobody but Apple can so swiftly usher in. The last time Apple ventured into such an undertaking in 2006, the company had ditched IBM’s PowerPC ISA and processors in favor of Intel x86 designs. Today, Intel is being ditched in favor of the company’s own in-house processors and CPU microarchitectures, built upon the Arm ISA.
The new processor is called the Apple M1, the company’s first SoC designed with Macs in mind. With four large performance cores, four efficiency cores, and an 8-GPU core GPU, it features 16 billion transistors on a 5nm process node. Apple’s is starting a new SoC naming scheme for this new family of processors, but at least on paper it looks a lot like an A14X.
Today’s event contained a ton of new official announcements, but also was lacking (in typical Apple fashion) in detail. Today, we’re going to be dissecting the new Apple M1 news, as well as doing a microarchitectural deep dive based on the already-released Apple A14 SoC.
