Memory 

Your Mac relies on memory to keep the files and apps you’re running open and available. Memory stores data temporarily, providing much faster access to your apps and files than storage.

M-series chips include high-performance unified memory, which is more efficient than traditional RAM. This single pool of high-performance memory allows apps to efficiently share data between the CPU, GPU and Neural Engine — so everything you do is fast and fluid. This means you can do more with unified memory than you could with the same amount of traditional RAM.

The amount of memory that’s right for you depends on how you will use your Mac. The more memory you choose, the more apps you can run simultaneously and the better they will perform.

18GB: Great for browsing online, streaming movies, messaging with friends and family, editing photos and personal video, casual gaming, and running everyday productivity apps. And for multitasking across a large number of apps, including professional video editing.

32GB or more: Best if you typically work on advanced projects that require enormous files and content libraries, or multitasking with memory-intensive pro apps.

Note: Unified memory is not user accessible. If you think you may need additional memory, it’s a good idea to add it now.
