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).<p>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.
