Dunno, the M1 CPU package is tiny, thin, power efficient, etc. It's got 4 memory chips inside the package. I don't see any particular reason why a slightly larger package could have 4 memory chips on one side, and 4 chips on the other to double the memory bandwidth and memory size.
However the M1 is already pretty large (16B transistors), upgrading to 8 fast cores is going to significantly increase that. Maybe they will just go to a dual CPU configuration which would double the cores, memory bandwidth, and total ram.
Or move the GPU and ML accelerator offchip.
- davidf18 6y agoI'm guessing the next "M2" chip will be fabbed on the upcoming TSMC 5nm process, 2nd version. In 2022 there is projected to be the TSMC 4nm process. Thus, there will be room for more transistors. Expect also a density increase and capacity for DRAM chips (and SSD chips).
