Memory access on the Apple M1 processor
Great practical information. Nice to see people who know what they are talking about putting data out there. I hope eventually these persistent HN memes about M1 memory will die: that it's "on-die" (it's not), that it's the only CPU using LPDDR4X-4267 (it's not), or that it's faster because the memory is 2mm closer to the CPU (not that either).It's faster because it has more microarchitectural resources. It can load and store more, and it can do with a single core what an Intel part needs all cores to accomplish.
