What’s the difference between Apple’s 192 GB ‘unified memory’ and a Gaming PC’s 192 GB DDR5 memory?
In: Technology
The unified memory has more direct access to the cpu. The m3 max has 400GB/s of memory bandwidth. DDR5-6400 is like 50GB/s.
Unified mem’ry is like having everything in one place for quicker access, while DDR5 memory is like having separate compartments, both are fast, just different setups!
Imagine you have a chocolate ice cream cake, with vanilla ice cream. The goal is to get a bit of cake and ice cream with each bite.
Unified memory is like having a layer of ice cream in between 2 layers of chocolate cake.
PC DDR5 is like having chocolate cake and a bowl of vanilla ice cream on the side.
They are technically the same thing, but with Unified you just use your fork and bam you got chocolate cake and ice cream in one motion, where as PC DDR5 you have to scoop some ice cream 1st, then get some cake on there before you take a bite.
