It also doesn’t hurt that Apple puts the RAM on the SoC and gives it a truckload of bandwidth. DDR5 is about 70GB/s, meanwhile the M4 Max is around 540GB/s.

I didn’t know AMD had managed to switch over to unified memory too. Managing that while remaining x86 compatible is quite an achievement!

Yeah “universal memory” is the holy grail, seemingly as hard to find as it as well.
The articles on Wikipedia about the related tech is great, it’ll mention something like “Developers expect commercialisation to happen relatively soon” and then link to an article from 2004, or research papers from the 1980s.
