It’s not that it’s more efficient, it’s simply used less than in conventional PC architecture.
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.
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.
A weeklong battery life, efficient cores, rapid response time, and great software environment make it a great choice…at 16GB for my needs. I will not recommend 8GB to any user at all going forward. It’s marketing malarkey with no future proofing, degrading the viable longevity of the machine.
There’s no conversation to continue. Glass is glass, and 8GB is 8GB, as well as being a joke.
If it’s great for your needs, the base model isn’t for you. You can stream video with have 30 tabs open in Safari and only use 4.6GB of UM on an M1 Mac. I just verified for you.
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.
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!!!
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.
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 running common tasks 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.
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
The only memory-utilization-related advantage gained by sharing memory between the CPU and GPU is zero-copy operations between the CPU and GPU. The occasional texture upload and framebuffer access is nowhere near enough to make 8 GiB the functional equivalent of 16 GiB.
If you want to see something “written explicitly to utilize [a unified memory] architecture,” look no further than the Nintendo Switch. The operating system and applications are designed specifically for the hardware, and even first-party titles are choked by the hardware’s memory capacity and bandwidth.
The Tegra is similar being an SoC, however it does not possess nearly as many dedicated independent processing cores designed around specialized processes.
The M1 has 10-core CPU with 8 performance cores and 2 efficiency cores, a 16-core GPU, a 16-core Neural Engine, and all with 200GB/s memory bandwidth.
The M1-3 is still miles ahead of the Tegra, I don’t disagree. My point was that software designed specifically for a platform can’t make up for the platform’s shortcomings. The SOC itself is excellently designed to meet needs well into the future, but that 8 GiB of total system memory on the base model is unfortunately a shortcoming.
Apple’s use of memory compression stops it from being too noticeable, but it’s going to become a problem as application memory requirements grow (like with the Switch).
Sure, but no one is saying 8GB is good enough for everyone. It’s a base model. Grandma can use it to check her Facebook and do online banking. It’s good for plenty of basic users. I have an M1 Mini with 8GB that I use as a home server. It works great, but I need my M2 MBP with 16GB UM to use FCP, PS, and Logic Pro. With that, I can master 4K HDR in FCP from an unmastered source in Logic Pro without high memory pressure, let alone swap. There’s no way I’d have the same performance from a PC with 16GB of RAM in Adobe Premiere and Pro Tools. I’ve been there before.
8GB really is a suitable low-end configuration, and most Mac users would agree. I’m not surprised a magazine dedicated to PC gaming hardware thinks otherwise.
UM on an SoC is not the same thing as RAM on a PC with a CPU and GPU. 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 conventional PC architecture.
MacOS is also designed specifically to leverage the hardware, so practical use is the only legitimate comparison to a PC.
Maybe PC Gamer isn’t the most informed reviewer of technology outside of PCs.

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

“Your powers are quaint, you must be popular with the children”
That’s on my M1 Mac Mini that I use as a server. I use an M2 with 16GB of UM for FCP, PS, and Logic Pro.

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.
