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.
Just wanted to point out that the number 1 performance blocker in the CPU is memory. In the general case, if you’re wasting memory, you’re wasting CPU. These two things really cannot be talked about in isolation.
No, that’s the other way round. You either have high CPU load and low memory, or low CPU load and high memory.
I’m not sure what metric you’re using to determine this. The bottom line is, if you’re trying to get the CPU to really fly, using memory efficiently is just as important (if not more) than the actual instructions you send to it. The reason for this is the high latency required to go out to external memory. This is performance 101.
