Comment on Apple keeps flogging 8GB of RAM for its Mac computers but it's still a dead horse
disguy_ovahea@lemmy.world 5 months agoUM on an SoC is not the same thing as RAM on a PC. It’s purely a storage liaison, since data is passed directly from core to core.
It’s not that it’s more efficient, it’s simply used less than in PC architecture.
What a load of nonsense. You’ve got no idea how a computer works. RAM isn’t just used for passing data between cores. If anything that’s more the role of cache although even that isn’t strictly accurate.
Whether a system has a discrete GPU or not doesn’t really factor into the discussion one way or another, although even if it did having more RAM would be even more important without a discrete GPU because a portion of the system RAM gets utilized as VRAM.
Guessing you haven’t rear the article. That quote is from apple not author, he is actually 100% against it throughout the article.
This is a truly terrible article.
Like why not test these things? This just sounds like ai generated garbage.
That being said, 8gb is an abysmally low amount of ram in 2024. I had a mid range surface in 2014 that had that much ram. And the upcharge for more is quite ridiculous too.
I know it’s pc ram but I bought 64gb of ddr4 3600mhz for like $130. How on earth is apple charging $200 for 8!!!
Looks like you didn’t read the article either.
Overall, I’m using 12.5GB of memory and the only application I have open is Chrome. Oh, and did I mention I’m typing this on a 16GB MacBook Air? I used to have an 8GB Apple silicon Air and to be frank it was a nightmare, constantly running out of memory just browsing the web.
Earlier it’s mentioned that they have 15 tabs open. I don’t like a lot of things they do in “gaming journalism” but on this article they’re spot on. Apple is full of shit in saying 8GB is enough by today’s standards. 8GB is a fuckin joke, and you can’t add any RAM later.
That doesn’t make sense. I have the 8GB M2 and don’t have any issues with 20+ tabs, video calling, torrents, Luminar, Little Snitch, etc open right now.
15 tabs of Safari, which is demonstrably a better browser by some opinions due to its efficiency and available privacy configuration options. What if you prefer Chrome or Firefox?
I will argue in Apple’s defense that their stack includes very effective libraries that intrinsically made applications on Mac OS better in many regards, but 8GB is still 8GB, and an SoC isn’t upgradeable. Competition has far cheaper 16GB options, and Apple is back to looking like complete assholes again.
That’s because PC people try to equate specs in dissimilar architecture with an OS that is not written explicitly to utilize that architecture. They haven’t read enough about it or experienced it in practice to have an informed opinion. We can get downvoted together on our “sub standard hardware” that works wonderfully. lol
Oh no I read the article, I just don’t consider that testing.
It’s not really apt to compare using ram on a browser on one computer and extract that to another, there’s a lot of complicated ram and cache management that happens in the background.
Testing would involve getting a 8gb ram Mac computer and testing it using common task to see if you can measure poorer performance, be it lag, stutters or frame drops.
You do have a point, but I think the intent of the article is to convey the common understanding that Apple is leaning on sales tactics to convince people of a thing that anyone with technical acumen sees through immediately. Regardless of how efficient Mach/Darwin is, it’s still apples to apples (pun intended) to understand how quickly 8GB fills up in 2024. For those who need a fully quantitative performance measurement between 8 and 16GB, with enough applications loaded to display the thrashing that starts happening, they’re not really the audience. THAT audience is busy reading about gardening tips, lifestyle, and celebrity gossip.
Written by someone who apparently has no understanding of virtual memory. Chrome may claim 500MB per tab but I’ll eat my hat if the majority of that isn’t shared between tabs and paged out.
If I’m misunderstanding then how the fuck is chrome with it’s 35+ open tabs functioning on my 16GB M1 machine (with a full other application load including IDE’s and docker (with 8GB allocated)
I have plenty of understanding of what virtual memory memory is. For one, virtual memory is orders of magnitude slower than physical RAM.
My point still stands, 8gb is fine if all you do is light web browsing and writing documents which is basically nothing, but at that point you don’t need a 2024 Macbook anything, you could use a older M1 Macbook and be perfectly happy.
All web browsers will use up as much ram as possible, that doesn’t mean they need it.
Even you don’t have a device with 8gb of memory, just because it’s usable doesn’t mean that’s it’s optimal, or that it’s not a ripoff to charge $200 for another 8gb.
Your 64 gigs of ram probably uses 10x the power and takes up significantly more space than the single memory chip that’s on the M1-M3s die. And yet it still has less bandwidth than the M1, and on top of that the M1 utilizes it more efficiently than a “normal” desktop or laptop can since there’s one pool of memory for RAM RAM and VRAM.

Chat GPT guestimates 57GB/s for dual channel DDR4 at 3600mhz
$1000 for 8 gigs of RAM in the Air is whatever. $1200 for 8 gigs of ram in the Pro was not great. But 1600 for 8 gigs of ram in the new M3 MBP is really awful.
the M1 utilizes it more efficiently than a “normal” desktop or laptop can since there’s one pool of memory for RAM RAM and VRAM.
That’s not how it works, unfortunately.
A UMA (unified memory architecture) enables zero-copy texture uploads and frame buffer access, but that’s not likely to constitute notable memory savings outside games or GPU-accelerated photo editing. Most of the memory is going to be consumed by applications running on the CPU anyway, and that’s not something that can be improved by sharing memory between the CPU and GPU.
And yet [your 64 gigs of ram] still has less bandwidth than the M1
It’s by necessity that the M1 has higher memory bandwidth. UMA comes with the drawback of the GPU and CPU having to share that memory, and there’s only so much bandwidth to go around. GPU cores are bandwidth hungry, which is mitigated by either using a pile of L2 cache or by giving the system better memory bandwidth.
Memory bandwidth is useless if you run out of memory and need to swap.
GPU not having it’s own pool of memory is really going to help to.
Pigs fly in apple land.

It’s not that you’re wrong from a philosophical perspective with that, it’s that you’re factually incorrect. Memory addresses don’t suddenly shrink or expand depending on where they exist on the bus or the CPU. Being on the SoC doesn’t magically make RAM used less by the OS and applications, as the mach kernel, Darwin, and various MacOS layers still address the same amount of memory as they would on traditional PC architecture.
Memory is memory, just like glass is glass, and glass will still scratch at a level 7 just like 8GB of RAM holds the same amount of information as…8GB of RAM.
The article actually quantitatively tests this too by pointing out their memory usage with Chrome and different numbers of tabs open.
Looks like you didn’t read the article.

You should familiarize yourself with the architecture before commenting. The GPU is broken into several cores of the SoC, along with the roles of the CPU. The UM is not part of the SoC. However, data is passed from what could be referred to as the CPU to what could be referred to as the GPU without interacting with UM.

I’m actually deeply familiar with the architecture, and how caches, memory, and UM’s work. I understand all of that. None of that changes the storage available. Having high memory bandwidth to load/unload memory addresses doesn’t fix the issue of the environment easily exceeding 8GB. I also understand the caching principles and how you actually want RAM utilization to be higher for faster responsiveness. 8GB is still 8GB, and a joke.

Use your experience and analyze Apple’s M SoC before we continue this conversation.
