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.
And why they solder the RAM, or even worse make it part of the SoC.
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.
BUT BUT you’ll get 5% fasTEr SpeED!!! And MOrE seCuRiTy!!!
Well. The claim they made still holds true, despit how I dislike this design choice. It is faster, and more secure (though attacks on NAND chips are hard and require high skill levels that most attacker won’t posses).
And add one more: it saves power when using LPDDR5 rather DDR5. To a laptop that battery life matters a lot, I agree that’s important. However, I have no idea how much standby or active time it gain by using LPDDR5.
In this particular case the RAM is part of the chip as an attempt to squeeze more performance. Nowadays, processors have become too fast but it’s useless if the rest of the components don’t catch up. The traditional memory architecture has become a bottleneck the same way HDDs were before the introduction of SSDs.
You’ll see this same trend extend to Windows laptops as they shift to Snapdragon processors too.
People do like to downplay this, but SoC is the future. There’s no way to get performance over a system bus anymore.
