Apple on Tuesday unveiled a new MacBook Air, MacBook Pro, and Mac mini, making up the first wave of Macs powered by Apple Silicon, and AnandTech has since published a deep dive into Apple’s brand new M1 custom chip at the heart of the new machines.
The article begins by picking through the admittedly scant details that Apple’s event offered about the M1 chip’s design, yet manages to extrapolate some interesting tidbits regarding the processor’s packaging and architecture.
Beginning with the M1’s unified memory architecture, AnandTech notes that the packaging style keeps the embedded memory off to the side of the compute die rather on top of it, ensuring the chips can be efficiently cooled, which suggests Apple is using a 128-bit DRAM bus similar to that found in previous A-X chips.
