"complementing the Neural Accelerators in the CPU and GPU" seems to be a misprint; I don't believe they have the accelerators in the CPU too.

Still super interesting architecture with accelerators in each GPU core _and_ a dedicated neural engine. Any links to software documentation for how to leverage both together, or when to leverage one vs the other?

Serious questions. How is Asahi these days? Is it ready as a daily driver? Is it getting support from Apple or are they hostile to it? Are there missing features? And can I run KDE on it?

nevermind. Found this. Still a ways to go. https://asahilinux.org/docs/platform/feature-support/m4/#tab...

Asahi will probably only ever be feasible for years-old hardware. macOS is a total non-starter for me, so maybe one day I’ll end up with one of these, but only as some kind of tertiary / retro machine.

And the fastest M4 max was already fastest single and multicore CPU by a decent margin, while the fastest non-Apple CPU was only specialized for single or multi.

The single thread performance for modern high performance CPUs are all very close to each other. Apple's latest usually has a small advantage because they're the first to use TSMC's latest nodes, which is good for something like 15-20%. The fastest multicore CPUs are the ones with a lot of cores, e.g. 64+ core Threadrippers. These have approximately the same single-core performance as everything else from the same ge…

I was going by Geekbench. If it's broken then yeah.

Cool. My maxxed out M4 Max MBP is scheduled for delivery tomorrow. Guess I’ll return it.

The M5 Pro/Max models are likely going to arrive in March (but maybe earlier)

Oh, the M5s available max out at 32GB ram, even in the MBP. That’s a nonstarter for me in a pro machine.

Yeah I love my M1 iPad Pro. But the "liquid glass" update made it feel slower. Really only the 'unlock' feels slower, once I'm using it it's fine. But it's slightly annoying and does make me want to update this year to the m5. But it's a glorified Kindle and YouTube box, so I'm hesitating a little bit.

my dad's got a pre AS iPad Pro and it's so bad after updating to 26. My 6th gen iPad on iOS 17 felt faster than this

I have a 5th gen? Can’t even remember now it’s so old. Nothing works anymore except Netflix, YouTube and Disney, and that only after a minute or so.

Which is fine, since it’s exclusively used to watch a kids show for a half an hour a day.

…but it’s also super sad to see a once fantastic piece of kit to degrade so much primarily due to software.

It’s unfortunate that this announcement is still unspecific about what they improved in the Neural Engine. Since all we know about the Neural Engine comes from Apple papers or reverse engineering efforts ( https://github.com/hollance/neural-engine ), it’s plausible that they addressed some quirks to enable better transformer performance. They have written quite interesting papers on transformers on the Neural Engine:…

My guess is that they moved the systolic arrays inside the GPU cores just like how it's done in modern NVIDIA chips.

That's the only way to speed up MLX 4x compared to M4.

Yeah, given all the people with passion/ability for low-level reverse engineering have left the project, I don’t think we should ever expect to get greater than M2 support from Asahi. Maybe one day another project will pick up the ideas, but for anyone not wanting to use years old hardware, the dream of Linux almost natively existing on modern Apple silicon remains just that: a dream.

Base models only: - M1 | 5 nm | 8 (4P+4E) | GPU 7–8 | 16-core Neural | Memory Bandwidth: 68.25 GB/s | Unified Memory: 16 GB | Geekbench6 ~2346 / 8346 - M2 | 5 nm (G2) | 8 (4P+4E) | GPU 8–10 | 16-core Neural | Memory Bandwidth: 100 GB/s | Unified Memory: 24 GB | Geekbench6 ~2586 / 9672 - M3 | 3 nm (first-gen) | 8 (4P+4E) | GPU 8–10 | 16-core Neural | Memory Bandwidth: 100 GB/s | Unified Memory: 24 GB | Geekbench6 ~296…

Interesting to see that over 5 years (M1 was 2020), the benchmark performance has not quite doubled. Is this an indictment of Moore's law, or just Apple over-speccing the M1 and slowly decreasing that over time?

Moore's law has never been an absolute and it's also about the number of transistors per mm/^2 ... not speed. Sometimes progress is a little faster and sometimes it's a little slower.

I’m trying to find any reason I can that my M1 Max needs replacement; it’s hard. How do you justify it?

You should wait until next Fall if you don't really need to replace your M1 Max. Rumors say that Apple's going to redesign the Macbook Pros next year with an OLED screen.

I would rather buy the last refresh of the old design. Waiting for a redesign is risky, as some redesings are just bad (like the touchbar MBP). And Apple is opinionated enough that it often refuses to admit its mistakes and sticks to them for years.

A lot of Apple hardware is impressive on paper, but I will never buy a Mac that can't run Linux. I simply don't want to live in Apple's walled garden. Then there is the whole ARM vs x86 issue. Even if a compatible Linux distro were made, I expect to run all kinds of software on my desktop rig including games, and ARM is still a dead end for that. For laptops, it's probably a sensible choice now, but we're still far f…

> A lot of Apple hardware is impressive on paper, but I will never buy a Mac that can't run Linux. They run Linux actually very well, have you ever tried Parallels or VMware Fusion? Especially Parallels ships with good softwaer drivers for 2d/3d/video acceleration, suspend, and integration into the host OS. If that is not your thing, the new native container solution in Tahoe can run container from dockerhub and co.…

... or UTM. I have run windows and Linux on my M1 MB Pro with plenty of success.

Windows - because I needed it for a single application.

Linux - has been extremely useful as a compliment to small arm SBCs that I run. eg: Compiling a kernel is much faster there than on (say) a Raspberry Pi. Also, USB device sharing makes working with vfat/ext4 filesystems on small memory cards a breeze.
