Why is Apple's M1 chip so fast?

Then, make desktops/laptops with 4 or 8 channels. We'd need more dimms, of a smaller size.

Only if you use dimms. If you use the LPDDR4x-4266 each chip has 2 channels x 16 bits. So the M1 has 4 chips and a total of eight 16 bit wide channels.

Does the 8GB variant have all 8 channels or just 4?

My guess is it's the same and using the half density chip in the same family, but I'm just guessing.
