Since 8GB unified memory is "equivalent to a 16GB non Mac" Is 128GB unified memory MacBook basically a 256GB Nvidia GPU(s)?

- lucasyvas 3y agoThey are not equivalent - it's pure marketing BS.
- nottorp 3y ago> Since 8GB unified memory is "equivalent to a 16GB non Mac" Yeah, right.
- treprinum 3y agoNot in the machine learning world ;-) You'd need to switch to marketing workloads to make 8GB = 16GB.
- jug 3y agoI think that one is mostly marketing but there's a grain of truth in terms of the combined effect of unified memory (which is fast as hell) and macOS memory compression. But I wouldn't put 8 GB past similar to 10-12 GB on another system without these features.
- moondev 3y agoSay I want to launch a vm with 8GB reserved memory. On a 10-12 GB machine I would have 2 to 4GB of memory left to actually allocate to the system. I don't see how unified memory magically fixes this. It's actually worse because even more memory has to be shared with the GPU. This is like saying a 8GB disk is actually like a 10-12GB disk elsewhere.
