[QUOTE="desiibond, post: 2522051, member: 23023"] No, it is not that simple. Unified memory is not just same memory for CPU and GPU. From I remember, in a Mac [LIST] [*]SSD and memory controllers are on the SoC. [*]Memory is on the SoC, right next to the CPU and GPU cores. [*]SSD and SoC are connected via high bandwidth channels. [*]As SSD can deliver data instantaneously, OS need not keep large amount of data in memory. This is why Apple says that 8GB on Mac is like 16GB on PC (I do hate 8GB Macs that are sold for 1L or more). [/LIST] Does it help in real world performance? It did work really well when Apple started migration to M1. Application load time, compilation and rendering was so much more faster. Apple Mx chips showed clear difference in speeds 'in real world usage'. It's a win either way for users.
