![]() ![]() Efficiency (low power consumption) CPU core (Icestorm 4core), (5) Neural Engine at the bottom left of the chip.įor example, the GPU of M1 has twice as many cores as A14 GPU, so the GPU area is larger than that of A14. They both have all the common components – (1) GPU on the top of the chip, (2) system level cache memory below it, (3) high-performance CPU core (Firestorm 4core) on the bottom left, and (4) high on the right side. Let’s have a look at the layout of the main blocks in the chip. A13 is used on iPhone11 and A14 is used on iPhone12. Just like the case with the announcement of semiconductors, the right side of Figure 2 is very likely an edited image for explanation.įigure 3 M1 Unified Memory Improvement of A13, A14, M1 SoC chipsįigure 4 shows three recent Apple chip photos. ![]() This is because the silicon surface is attached toward the package substrate side. The M1 SoC part on the right of Figure 2 announced by Apple does not actually show the real SoC part – if you disassemble your Mac computer and remove the metal cover, you should be able to see the back of the SoC. This packaging method is called SiP (System in Package). ![]() It is covered with a metal cover (left side of Figure 2), and the inside is a package board with M1 SoC (left side), two DRAMs (right side), and capacitors (top and bottom) (right side of Figure 2). Now, let’s take a look at the components of M1. In 2006, Apple introduced an Intel CPU, and in 2020, they decided to use their own – M1. Before 1994, Apple was using the Motorola MC68000 series, but in 1994 switched to PowerPC. This is the third time Apple has made a major CPU change.
