Apple uses HBM, basically RAM on the same die as the CPU. It has a lot more memory bandwidth than typically PC dram, but still less than many GPUs. (Although the highest end macs have bandwidth that is in the same ballpark as GPUs)
- jsheard 2y agoApple does not use HBM, they use LPDDR. The way they use it is similar in principle to HBM (on-package, very wide bus) but it's not the same thing.
- karmakaze 2y agoRight so Apple uses high-bandwidth memory, but not HBM.
- justincormack 2y agoIts not HBM, which GPUs tend to use, but it is on package and wider interface than other PCs
