what the chip arquitecture has with I/O operations?๐
M3 is a SoC, or System on a Chip. The whole M3 is all the things. I/O, CPU, GPU, Bus, RAM and even storage. Everything is on a single custom ARM chip.
That is not correct. The DRAM is not part of the same die that the SoC is on. It is separate packages directly beside the SoC. The storage is also separate packages.
If it was all one die it would be huge and have poor yields.
This is incorrect; the M-series chips all use standard LPDDR4X (M1) or LPDDR5 (M2/M3) chips, not part of the SoC, and soldered directly next to the CPU. The SSDs are also standard NAND chips, again external to the SoC, connected via PCIe.
