As someone who mucks around with running LLMs and other large models on my computer the 32GB maximum RAM is a show-stopper for me. I'm on a M2 with 64GB at the moment and I'm already regretting not going for 96 or even 128. I want to be able to run a large model AND other apps at the same time.

You have a higher tier M2. This is the base M4. The comparison is apples to oranges.

It's literally Apple to Apple

What's with the green iMac picture? https://www.apple.com/newsroom/images/2024/10/apple-introduc... It only shows two USB-C ports while further down the marketing material talks about "all four USB-C ports". EDIT: the low-end 8-core model for $1300 only has two ports. It also has what looks like a rear-facing camera in the stand cutout. What is that for? EDIT: It's the magnetic power connector. I did not expect that…

The gigabit ethernet port is in the power brick.

> 16GB base RAM, they finally did it. I've paid €200 for 128GB RAM in my PC. How much does Apple charge for 128GB of memory?

Isn’t Apple’s RAM inside CPU package? I think it might not be possible to put together a system (at least with consumer parts) that matches their memory bandwidth. On the other hand, they are limited in capacity. It is a trade off, it is silly to pretend they are just limiting memory capacity out of the vileness of their hearts or something.

No, but their marketing department would like you to think so.

They are limiting memory capacity and charging you 8x-10x reasonable retail price for upgrades, so that their profit margins stay high. Whether or not that's vile is something I leave to you to decide.

We should do a "Most HackerNews HackerNews Comment Of The Year" award each year; in homage to the O.G. [1]. I'd like to nominate this comment.

Now if only they could figure out how to allow charging the Magic Mouse while it’s being used. I guess that technology is still years away.

I'm surprised Apple didn't co-opt charging mousepad tech, like what Logitech uses: https://www.logitechg.com/en-us/innovation/powerplay.html

Apple engineers probably still have PTSD from trying to get the AirPower mat to work, I doubt they'll touch non-magnetic wireless charging again.

> necessary for fast enough transfer speeds Source?

When was the last time you saw a GPU with slottable memory? For transfer speeds, look at the data sheets for the M series. Much faster than DDR4 or DDR5 RAM. In the ballpark of GPU memory.

Would the people who were buying the baseline 8GB model (presumably just for general computing/office work) care about the GPU being slightly slower, though?

I bet that the extreme lag when you run out of memory because you have an Electron app or two, several browser tabs and something like Excel is way more noticeable.

Hardly anyone is using Macs for gaming these days and almost anybody who does something GPU intense would need more than 16GB anyway.

Sure, but to be honest, I don’t think you should be shipping a high-spec computer with a built-in screen. Anything high-spec should be broken into at least a separate screen and computer. The screen is such a major point of failure. I’ve seen so many iMacs and MacBooks with broken screens where the end solution is to replace the entire device, which is a waste. It’s that much more of a waste if you are getting a high…

> The screen is such a major point of failure. The screen of an iMac (at least the 5K 27" one) is the part that still has value, so its annoying when you can't use it on new hardware.

Yes, that is annoying. There’s also such a massive price difference between 4K and 5K monitors. I’ve decided just to accept 4K everywhere because it’s so much cheaper. But I would consider getting a 5K iMac.

I could never justify getting an iMac. All the downsides of a laptop & desktop in one; not upgradeable and not portable. Leaves me wondering how many of these Apple actually sell. A Mac Mini with a separate screen feels like it makes far more sense.

The iMacs very much aren't their main seller. A couple of key demographics use it though: * Families with a shared computer in a common room. Super simple to setup, no fiddling, low price. In the video Apple showcased this use case. My parents have an M3 imac and it works great. They had their last iMac for ten years. * Businesses buy these for reception areas and customers see the Apple logo on the back. Easy soluti…

I really wish that "elite" LLM folks like yourself or many others in the field would just abandon apple/mac.

Yes, they make better laptops from a hardware perspective. No, M series chips are not actually competitive with Nvidia hardware on anything except cheap (and relatively slow) inference of big models.

The fact that windows laptops are considered DOA despite the insane amount of inertia behind Nvidia GPUs is just sad. I want a world where Dell/Lenovo can actually convince folks like you or other "elites" to use their shit. The XPS should be a better laptop than the macbook pro. Yet, I have to watch as the technical elites fawn over a company which continues to sell a starting level un-upgradable laptop with 8gb of ram and a gimped "SSD" in 2024 (this was criminal to do back in 2018) all because other companies can't make a good keyboard or touchpad.

I have a similar old-man yelling at cloud tier rant about the slow death of X86...

Note: The 24” iMac is never going to be the platform of choice for HackerNews readers.

I recommend these to friends who want a simple computer setup. Many people have dramatically different needs and wants than I do as a software professional.

Apple knows this, and so it markets it to them rather than to us.
