It doesn't make much sense to me. The M1 is designed to have memory in the same package as the processor. This leads to reduced latency and increased bandwidth.

It doesn't make much sense to me. The M1 is designed to have memory in the same package as the processor. This leads to reduced latency and increased bandwidth. Moving to off-package memory might totally destroy its performance, and there is an upper limit on how much memory can go in the package. The M1 Ultra is already a little light on memory for its price and processing power; it would have much too little memory for a cloud host.
