There were a number of exciting announcements from Apple at WWDC 2024, from macOS Sequoia to Apple Intelligence. However, a subtle addition to Xcode 16 — the development environment for Apple platforms, like iOS and macOS — is a feature called Predictive Code Completion. Unfortunately, if you bought into Apple’s claim that 8GB of unified memory was enough for base-model Apple silicon Macs, you won’t be able to use it. There’s a memory requirement for Predictive Code Completion in Xcode 16, and it’s the closest thing we’ll get from Apple to an admission that 8GB of memory isn’t really enough for a new Mac in 2024.
There are real world performance benefits to ram being as close as possible to the CPU, so it’s not entirely without merit. But that’s what CAMM modules are for.
Apple’s SoC long predates CAMM.
Dell first showed off CAMM in 2022, and it only became JEDEC standardised in December 2023.
That said, if Dell can create a really good memory standard and get JEDEC to make it an industry standard, so can Apple. They just chose not to.
