I just want to point out that anything you ask ChatGPT about that hasn't been discussed 1000 times on Reddit or Wikipedia is going to be wrong, and it will only be "right" in the sense that it aligns with the artificial consensus created on those platforms. Of course the author probably did that as a joke.

Pretty much! A precedent-fueled prediction engine can’t predict the unprecedented.

The lack of native games on Apple Silicon is one of the greatest crimes ever committed against computing. I got Fallout 3 working on my M2 MBP as well as it did on Windows back in the day. Temps were cool, battery was decent. If they sold my college years gaming collection (15-ish years ago) in a way that ran natively through GoG or Steam, I'd buy every single title .

Porting games natively to macOS is a waste of developer time. Apple has already depreciated vast swathes of 32-bit games that were never updated to support 64-bit x86 or Apple Silicon. Developers that give macOS the same level of attention as Windows don't get the same level of support that Microsoft offers in return.

Not to mention that Mac owners are a minority share of the PC gaming market. Linux has the right idea, if you don't translate the games then you'll never have true preservation.

It (LLMs in general) actually can make some very prescient hallucinations by making similar inferences across dissimilar domains, but they have since removed that feature to prevent liability and libel. GPT3 was much more useful in this capacity, especially before they started stress testing it on 4chan (Jan 2023)

DISCLAIMER: Only speaking for myself, not employers or affiliates. I've been pretty darn happy with the Puget Systems custom workstation I ordered last year before the memory craze started (especially since it has 192GiB of DDR5). I also ordered another family member a custom "Tiki" system from Falcon Northwest and that has also been quite excellent from what I've seen and they've told me. Now is obviously not the mo…

I wouldn’t count them as a big vendor, but I’ve only heard good things. Local shops around here charge like $99 to put a machine together, install an OS and run burn in testing. You get more choice than an outfit like puget, but less carefully tested part / cooling selection, etc. The last I checked, the really big players tended to add value add gimmicks (water cooling is a common one, custom psu form factors are an…

I picked both Puget Systems and Falcon Northwest because for the most part, both focus on pre-tested off-the-shelf parts with good reliability data from their own servicing.

My Puget Systems workstation for example has a simple AIO for cooling with some Noctua fans and a Fractal Design 7 XL full tower case.

The Tiki system I ordered for a family member from Falcon Northwest does have a custom case, but almost everything else is fairly standard inside. The super small form factor was important to them.

Could I have built either of these systems myself? Absolutely -- I've done that for at least prior 20 years or so, and I've built dozens for employers, but it sure was nice to buy one that just worked this time instead of having to having to fiddle with memory sticks or find exactly the right bios settings for stability, etc.

I'm well aware of the premium I paid but I can honestly say it has been incredibly nice to have a workstation that just works without having to fiddle with bios updates or hardware. I also don't really have the time to spare so I was entirely willing to trade funds for time.

No you don't understand, on Apple Silicon my CPU has comparable memory bandwidth to a $400 Pascal-era GPU. With the unified memory architecture, that means my iGPU gets 2016-levels of DDR transfer speed with none of the upsides of CUDA. It's the most cutting-edge hardware ever put in a personal computer, without a doubt.

Please show me on the 2016-era $400 Pascal GPU where you can install the 256 GB of VRAM.

Skyrim runs well [1] on my M2 mac mini through crossover and rosetta. So most older games will run even better.

The real question is what happens when they drop Rosetta. They promised they'll keep the APIs related to running 32 bit games but can we trust them?

[1] Not at 8k 240 fps of course.

There was some bad history between Apple and Nvidia. Perhaps with a new generation of leadership at Apple things might change. https://www.reddit.com/r/hardware/comments/1hmgmuf/apples_hi...

I wasn't in the room when it happened, but this is very different than the story told internally about why Apple became allergic to Nvidia. Arguably more petty. SJ has been dead for almost 15 year now, I imagine the C-suite might get over it at some point.

> Arguably more petty

I can believe it. IIRC Jobs also snubbed ATI once after they leaked the GPUs going in the next PowerMac model.

two semi interesting things to note around this: 1. Virtualization.framework seems to support some form of GPU passthrough from the host (granted, not eGPU - it's for the integrated GPU). I think the primary use case is having macOS guests get acceleration, while still sharing GPU time with the host. There is also a patch that recently hit QEMU mainline that supports using the "venus server" with virtio-gpu to suppor…

I experimented with booting Arm macOS 14-26 in QEMU a while back, building on the work of Alexander Graf for macOS 12-13, and reverse-engineered substantial parts of Hypervisor.framework, the in-kernel hypervisor, and a bit of Virtualization.framework. Got newer versions of Sequoia to boot past the log in screen, with GPU acceleration too. Unless there's another method I missed, the internal GPU "pass through" of Vir…

There's some randomness around Tahoe for FileVault and it crashing because Data is detected as not encrypted (and that's not OK on bare metal). If hitting that case you might need to enable FileVault inside the VM (and remember to sync aux storage afterwards if not done)

I'm curious and not an expert here, do you know why the TTFT is so much worse on Mac? To elaborate, the article just says that this step is compute bound, but I'm wondering whether it is just that simple or if it might also be less optimised in MLX?

Apple GPUs didn’t have tensor cores until the M5 (aka “a neural accelerator in each core”) and in the article’s charts that a M5 Pro significantly beats a M4 Max (while in other workloads it would be much smaller since Pro is ~1/2 Max). EDIT: since Aurornis beat me by 3 minutes, I’ll add another interesting tidbit instead :) NVIDIA tensor cores on consumer GPUs are massively less powerful per SM core than on their da…

@Ademeure Where do you think the market will be by the time, say year from now, when Apple has rolled out it's M6 generation? Do you think one more process node and architecture revision will be enough yet to tip the balance that local LLM starts to go mainstream?
