Base-model Macs won't be able to take advantage of Apple's flagship Xcode 16 feature: Predictive Code Completion.
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.
Someone who is buying a MacBook with the minimum specs probably isn’t the same person that’s going to run out and buy another one to get one specific feature in Xcode. Not trying to defend Apple here, but if you were a developer who would care about this, you probably would have paid for the upgrade when you bought it in the first place (or couldn’t afford it then or now).
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.
That's extremely dependent on the use case, but in my opinion, generally no. However CAMM has been released as an official JEDEC interface and does a good job at being a middle ground between repairability and speed.
It's an officially recognized spec, so Apple will ignore it as long as they can. Until they can find a way to make money from it or spin marketing as if it's some miraculous new invention of theirs, for something that should just be how it's done.
Yes, there are massive advantages. It’s basically what makes unified memory possible on modern Macs. Especially with all the interest in AI nowadays, you really don’t want a machine with a discrete GPU/VRAM, a discrete NPU, etc.
Take for example a modern high-end PC with an RTX 4090. Those only have 24GB VRAM and that VRAM is only accessible through the (relatively slow) PCIe bus. AI models can get really big, and 24GB can be too little for the bigger models. You can spec an M2 Ultra with 192GB RAM and almost all of it is accessible by the GPU directly. Even better, the GPU can access that without any need for copying data back and forth over the PCIe bus, so literally 0 overhead.
The advantages of this multiply when you have more dedicated silicon. For example: if you have an NPU, that can use the same memory pool and access the same shared data as the CPU and GPU with no overhead. The M series also have dedicated video encoder/decoder hardware, which again can access the unified memory with zero overhead.
For example: you could have an application that replaces the background on a video using AI. It takes a video, decompresses it using the video decoder , the decompressed video frames are immediately available to all other components. The GPU can then be used to pre-process the frames, the NPU can use the processed frames as input to some AI model and generate a new frame and the video encoder can immediately access that result and compress it into a new video file.
The overhead of just copying data for such an operation on a system with non-unified memory would be huge. That’s why I think that the AI revolution is going to be one of the driving factors in killing systems with non-unified memory architectures, at least for end-user devices.
And even if the out-of-the-box RAM is soldered to the machine, it should still be possible to add supplementary RAM that isn't soldered for when the system demands it. Other computers have worked like this in the past with chip RAM but a socket to add more.
For instance, I could absolutely see having certain models with LPCAMM expandability as a great move for Apple, particularly in the pro segment, so they’re not capped by whatever they can cram into their monolithic SoCs. But for most consumer (that is, non-engineer/non-developer users) applications, I don’t see them making it expandable.
Or more succinctly: they should absolutely put LPCAMM in the next generation of MBPs, in my opinion.
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.
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.
And the apple haters will keep making this exact same comment on every post using their 3rd laptop in ten years while I’m still using my 2014 MacBook daily with no issues.
Still gets security updates. All the software I need to run on it runs on it.
My email, desktop, and calendar all still sync with my newer desktop. I can still play StarCraft. I can join zoom meetings while running Roll 20. I can even run Premiere and do video editing… to a point.
I guess if you need the latest and greatest then you might have a point, but I don’t.
This whole thread is bitching about software bloat and Apple does that to stop the software bloat on older machines, but noooo that’s planned obsolescence. 🙄
This is pretty much it. People really just want to find reasons to hate Apple over the past 2 - 3 years. You're right, though, your Mac can run easily for 10+ years. You're good basically until the web browsers no longer support your OS version, which is more in the 12-15 year range.
In fairness, most computers built after around 2014-2016+ last way longer, performance started to level off not long after that. After all, devs write software for what people have, if everyone had 128 gigs of RAM we'd load everything we could think of into memory and you'd need it to keep up
Macs did have some incredible build quality though, the newer ones aren't holding up even close to as well. I'm still using a couple 2012 Macs to play videos, it's slow as hell when you interact, but once the video is playing it still looks and sounds good
These were obsolete the minute they were made, though... So it's not really planned obsolescence. I got one for free (MacBook Air), and it's always been trash.
I have an M2 MBA and it’s the best laptop I’ve ever owned or used, second to the M3 Max MBP I get to use for work. Silent, battery lasts all week, interface is fast and runs all my dev tools like a charm. Zero issues with the device.
