They also put controllers for hardware into the chip to improve performance. With so much of the system now in one chip, you will see speed improvements mostly because of the code optimization and memory being on-chip. While this is an announcement of the chip, it is more about how they have compiled MAC OS to run on the new chip and APIs to access the additional features such as neural engines and built-in GPU. Apple M1 Chip with 5-nanometer process and 16 billion transistors, also shows the memory on the CPU package. This is basically their own ARM processer similar to the processer used in the iPad and iPhone, but with more memory directly attached to the chip. Well, it looks like Apple did what they were saying they would, by announcing new MAC computers with their own processer they announced at their developer conference.
