Assuming you're referring to Apple Silicon's memory bandwidth, that is not necessarily because the memory is on-die. The bandwidth comes from having more channels to access memory. This gives the SoC a wider bus to increase throughput vs. your typical x86 system with two channels. For whatever reasons Intel/AMD decided that two channels is all the typical consumer chips can support now so it's on them.
On laptops right? Weve seen more channels for years elsewhere
Yes, on laptops, but even on most desktops now too. Higher number of channels is getting more limited to server systems.
Ah I see, thanks for breaking it down.
