It's easy to assume it's malicious. But instead this allows laptops to be thinner, cheaper, and have MUCH better performance.

Nearly all PC and laptops have 128 bit memory busses, which is a major bottleneck for iGPUs, as well as weird use cases like LLM.

However the M2 pro doubles the memory memory width. M3 Max doubles it again, twice as wide as an AMD threadripper.
