> M5 Ultra features a massive amount of high-bandwidth unified memory, up to 512GB, and delivers a staggering 1.2TB/s of unified memory bandwidth that is 50 percent higher than M3 Ultra.

Apple never needed to participate in the AI race to zero. Because they were already at the finish line years ago building their own chips that can run large >100B parameter AI models locally.

As someone who works in AI now, I have found it pretty amazing that Apple basically didn't do much with AI software, and focused more on the hardware side. I think this is what the future of AI is going to look like, local models run on your mac for your workflow.

It's possible that they're working on their own LLM that's going to work very well on their chips, and possibly outperform anything out there when they do release it.

nth mover advantage.
Has yet to materialise
>local models run on your mac for your workflow.

10 years ago 32GB ram laptops sounded too much. 8 was enough. These days even I would get that much ram since it’s soldered. 64GB is higher end.

In a few years we should see such high end hardware commonplace. Working with a local LLM to get work done is the ideal way to go which has mostly hardware limitation as of now that gets solved in due time.

> 10 years ago 32GB ram laptops sounded too much. 8 was enough. These days even I would get that much ram since it’s soldered. 64GB is higher end.

Ten years ago I got 64gb of ram in my laptop, same as I have now. I bought both for business and personal use. System ram capacity hasn't changed much in 10 years.

It makes me curious how old you were 10 years ago.

> Ten years ago I got 64gb of ram in my laptop

We were definitely outliers that long ago. I put 64 GB in a MacBook Pro back in 2019, and that was (a) overkill for everything I ever ran on that machine, and (b) stupidly expensive by 2019 standards (albeit almost affordable by 2026 standards)

|It's possible that they're working on their own LLM

Yep, Siri AI; they’re doing it in public.

‘Apple Foundation Model’
Didn't they fire half of siri team yesterday?
>I have found it pretty amazing that Apple basically didn't do much with AI software

The iPhone 15 was almost entirely marketed based upon AI (I would say fraudulently so, advertising features they still haven't delivered), and a huge portion of the OS work was on local AI or AI integration.

And for that matter Apple has been dumping enormous sums into their own AI development. Their failure to have a lot to show for it doesn't void the fact that they tried really, really hard.

It's bizarre how often this "Apple sat on the sidelines and let the AI people fight...so smart!" narrative appears on HN. Apple hasn't gone down the path of spending hundreds of billions on nvidia GPU data centres, but they absolutely tried really hard to matter in AI.

Is there anything comparable that runs Linux, doesn't necessarily look as good, but is perhaps (a lot) cheaper/fixable? Or is this really pretty optimal?

I mean this is not nvidia based right? It's all custom? So we can use it under Asahi perhaps?

I want to get something for my company to run local models, wondering what would be a good option.

I love linux and would be using it if the ARM support was better. It's just not there and most distros that support ARM do it a little poorly. I just haven't seen anything even remotely comparable to Apple Silicon and unfortunately Linux is struggling very hard to support it.
It's not quite that ARM support isn't good on Linux, it's that there aren't high-performance ARM chips with strong general-purpose software stacks. Like the Raspberry Pi is very well supported, but otherwise the only upmarket devices are things like Ampere workstations and hyperscaler server chips.
Asahi was stuck at M3 last time I checked it out.
M2 even.
Development on m3 is ongoing, m2 is supported
Strix platform maybe?
The PC platforms have anemic memory bandwidth in comparison. Eg, Strix Halo is 256GB/s max. If money is a bigger limiter than performance it can be an option though. As can Nvidia DGX Spark machines. (Also limited to 128GB memory and comparatively low bandwidth, but higher compute than Strix Halo.)
AFAIK, apple does not release drivers open source, asahi is a reverse-engineering endeavour and does not support GPU. For nvidia, there are both proprietary and open-source linux drivers. CUDA and inference works on linux with nvidia. I would recommend checking out this video of Alex Ziskind to shop for a computer to run local LLMs: https://www.youtube.com/watch?v=mevUEQcumzU&t=224s. TL;DR besides Apple he recommends, DGX Spark, Tenstorrent Wormhole N300, AMD Radeon 7900 and NVIDIA RTX 5090.
I guess, what I mean is: Why are these tiny aluminum boxes so optimal?

I just want my butt ugly repairable beast machine to do the same trick. Why is my ram not unified? I have an iGPU in my server, but it can't access the 64 GB ram (I got last year for 150 euro) directly or something? It's on the CPU right? Why did only Apple go for this architecture? So many questions...

well the good news is you can indeed already just have unified cpu/gpu memory on linux with an igpu on good old replaceable ram. i've done it on 8th gen intel stuff i picked up dirt cheap used. for the most part, running on the gpu wasn't faster (nor appreciably slower) than the cpu for the things i was doing, just more power efficient. overall bandwidth is relatively limited regardless which would be the bigger difference comparing against the m chips. and of course, good luck if you're hoping stuff like opencl support hasn't long ago been ripped out of whatever software you might perfectly reasonably expect to run this way today
You can't run Linux directly on these. Asahi Linux supports up to M2 only.

Linux runs very well in a VM on macOS. There are many good options for this, some free and open source (QEMU, UTM, Lima, Colima), some proprietary (VMware Fusion, Parallels).

But Linux in a VM doesn't get access to the real GPU, so model performance is limited. Those running on the CPU perform well, and those needing the GPU don't.

However, macOS on M-series macs is excellent for local models. (Maybe not as excellent as a box full of the best nVidia GPUs, but still excellent).

So if you're getting Apple hardware, like Linux, and want to run all of it locally, a fine setup for a machine to run local models, with agentic characteristics:

- macOS running one of the many local model runners. I used to use Ollama and Whisper, and now use llama.cpp instead of Ollama. Others use LM Studio, oMLX, etc. Provide HTTP endpoints to access the models.

- Linux in a VM for overall control and orchestration, with standard VM settings, and bridged networking so it appears as its own machine on your network. Also, in here provide a robust shared file server for shared state. Use this VM as your desktop and primary access to the machine, if you like Linux.

- Linux in a VM to launch ephemeral, volatile containers, with the containers using a memory-only tmpfs overlay on top of a read-only Linux filesystem in a VM disk image, with tools in this filesystem. Alternatively, a writable Linux filesystem in a VM disk image, with disk buffering set to use macOS host buffering and discard fsync requests. These settings optimise for container disk performance for data that's only ephemeral which will be deleted soon or on system shutdown. (You can combined both VMs, but need to use two VM disks to get equivalent behaviour, and be careful about VM disk configuration of the two disks.)

- Containers spawned within that second Linux VM can be spawned very quickly and run quickly, so are ideal for LLM agents that need a quick sandbox. These sandboxes generally run faster than a macOS sandbox, despite being on the same machine with VM overhead, because Linux is faster at some things. Teach the LLMs to store files and memories they want to keep in the shared file server.

1.2TB/s is 2/3 the speed of an nVidia 5090.

But you get a generic computer and much more RAM.

And you lose a couple of organs.

How much memory does that come with?
32 GB GDDR 7
is it still effectively 2/3rds? Don't know enough to compare a discrete GPU/CPU setup to something like this where it's more integrated
There is no magic, if the data you compute as atomic chunk don't fit in cache then memory bandwidth R/W limit kicks in and architecture does not matter. On contrary - having multi gpu setup of same price and same memory size with even slower memories may give you effectively much higher bandwidth but at the cost of power consumption.
The real downside for me is not having Linux support.

It would take Apple one or two engineers to make Linux life much easier on macs. But Linux is outside their walled garden so it's ignored.

I’m done with macOS.

My Mac Mini is strictly a headless server for llama.cpp.

I use a Linux workstation.

If I were limited to use Mac hardware , I would install Linux in VMware Fusion and work from there.

Same here. Sadly I think the voices like ours won't be heard, though, because Apple's looking for someone who's going to buy in on the whole ecosystem, and I think we're not it. Or at least I'm not.
It's worth noting that the 5090 (or the RTX Pro 6000 big brother with 92GB VRAM) will run rings around the Mac when it comes to compute.

My old 3090 is typically significantly faster (almost 2x token/s) than my M4 Max 128GB machine, as long as the model fits in the 24GB of VRAM.

In most situations it's a better idea to just buy tokens. But there are definitely cases when that's not an option. And then a machine like the M5 Ultra can allow you to do things locally for a fairly limited budget. And in a simpler package to manage than a machine with multiple GPUs.

I was so blown away at all the discourse surrounding "Apple fumbling on models". They should never have been in the model game to begin with. Apple crushes hardware over the last decade and that's a huge advantage today. In the end, massive models have proven to be very strong, but small models have proven to be good enough (especially with the recent Qwen 2.8 27B drop) and that's where I imagine the future will lie for consumers.
I suspected Apple would let everyone else blow all their money then, when the dust settles, deliver a better experience to end users and clean up.
Agreed. Apple doesn't innovate anymore, but they're generally pretty good at adapting once other people have.
I think this is a bit of a crazy statement. Everyone expects Apple to somehow build a category leading product every year. I'd expect something innovative every couple of years

* the iPhone * the iPad * apple watch * airpods * unified memory laptops and computers

Those are all products that either created a category or changed that industry.

I think that each of the products you name is the top or near the top of their category, but these weren't creating a category. I don't think my original comment says anything about "changing that industry", so that's a bit of a strawman. They absolutely change the industry they're in. They're just not first to any of those categories that you mentioned (maybe unified memory, I'm not sure).

They weren't the first smart phone, tablet, smart watch, or true wireless earbuds. They did a damn fine job making each of those though. I am typing this on a my work macbook wearing AirPods, and AppleWatch, listening to audio on my iPhone. Apple does a really good job with their products.

Realizing how surrounding by Apple I am...

They did participate early on with Apple Intelligence and failed miserably. Really good move to not double down and let the others explore the space first
I know they are a phone company, but I think they should focus on local models software, not only hardware.
Software wise there's plenty to choose from already. Ollama/llama.cpp, LM Studio, Lemonade, vllm etc. Anything Apple would bring to the table?
Maybe https://mlx-framework.org

FWIW, Ollama, LM Studio and Lemonade (and oMLX) also wrap Apple's MLX framework.

They aren't a phone company, and haven't been ever. They're a hardware company first
More like an "ecosystem company".

It's the Hardware, Software and Services in combination. None would work without the other (to reach the scale apple is)

Probably too young if it was easy these companies would still be around I miss them SGI, Sun, Digital, Acorn, particularly SGI and Acorn. All were roadkill of Wintel.
> They're a hardware company first

More specifically, they're a hardware dongle company first

Apple has the mlx framework. Most/all major software for running models locally support it. Apple also has RDMA for interconnecting multiple machines across Thunderbolt connections.
Uhhh, they are? They’re a hardware co for sure, but to say they aren’t focusing on on-device models is absurd on its face. They’ve spent over 2 years on Siri AI which is (mostly) local.
their strength has been hardware for over 30 years now
The last mainstream vertical computer company left from the 1980's, imagine if SGI, Sun, Digital, or Acorn were still around.
My 100k company only buys Mac laptops and you're calling them a phone company. Such an odd comment.
Its called cope...
False, they are a Marketing Company.
>fluid frame rates in demanding games like Mixtape.

not getting on that bandwagon but wasn't that not the most demanding game as its a just a nonstop cutscene.

it's not super well optimized I think. unreal engine 5 is taxing even without a lot of gameplay or stuff on screen
I'm not sure who that line is supposed to impress. Gamers focusing on graphically demanding AAA games would laugh at this. People who don't game much probably won't know whether this is good or not.
But it has the right creative vibe which is the point really. Apple has a general creative aesthetic which plays well with artsy games like mixtape.

It's a very deliberate choice when if it doesn't make sense to gamers.

cutscenes are often the most demanding part of a game!
There are some older games (not that old, one of the metal gear/raiden games had it, so like 10-15 years) where the cut scenes are actually prerendered video playback - so not very demanding. Don't know if mixtape does this though.
* it's artsy, which fits Apple's PR image

* it's critically acclaimed (86 metacritic, 10/10 IGN)

* whatever person decided this likely knows nothing about video games

* most importantly it's a modern game in UE5 that's COMING NATIVELY TO MAC, including to the App Store

What would you have put?

off the top of my head, Cyberpunk 2077.
Usable ram amounts in late October
Usable, not affordable.
Subjective
96GB -> 256GB upgrade costs 4000 GBP in UK or $5460. $34 for GB.

In US its $4000 upgade so $25 for 1GB.

Also:

> 512GB memory option for M5 Ultra coming late October

VAT?
I think the $34/GB figure might be inclusive of VAT and the $4560 not, which would be $28.5 otherwise. Not sure.
Oops sorry its just typo. Its 5460 not 4560.
AFAIK UK VAT is 20% and it's 27% higher price. Its just what you get for living in UK I guess.
That US price is before sales tax no?
Correct. It is better to go to delaware and purchase it.
Or just use Privacy.com and use an address in Delaware. Then you can buy it where ever.
How does this even work? You need to get the item delivered, and sales tax will incur in the state where it is delivered.
In the context of buying from UK, use Delaware (or any no-sales-tax state’s) mail forwarding company.
In that case you'll just pay import tax and its gonna be almost the same price, but 1 month later.
Delaware? For people in California, Oregon is way closer.
Agree. There are 5 states called NOMAD state where there is 0% sales tax.

New Hampshire, Oregon, Montana, Alaska, Delaware.

~12k for 80 core gpu with 256gb, 14k in October for 512gb. Seems like that could make for a very descent on prem inference server.
It cant be 14k for 512GB because 96 -> 256 upgrade alone cost $4000
Apple Studio with maxed out M5 Ultra, 256GB RAM and 16TB storage is 18,299$. The 512GB RAM version apparently is coming in October, considering that the difference between 96GB and 256GB is priced at 4000$, the 512GB upgrade must be eye watering.

So, on the mini the RAM upgrade runs at 25$ per GB on all tiers, the same as the Studio therefore the upgrade to 512 will probably cost 6400$.

The fully maxed out Apple Studio then will be 24699$. It's 17199$ if you don't upgrade the storage(1TB).

Nevertheless I itch to have one :)

So is downpayment on a house. I would buy the house and just pay for tokens as needed. The house will get more valuable and that wealth would buy a lot of tokens in the future - which will probably get cheaper.

EDIT: or buy AAPL. If I had bought Apple stock instead of buying a Mac LC II in 1992, then I would have about $2 million in Apple stock.

With the way RAM prices are going up, you could expect to make 20% profit on any purchase.
I tripled my money on my RAM purchase of three years ago. So, yes, for short-term appreciation that's hard to beat. But I don't think it's something that will continue.
Had I done that as well, then maybe I wouldn't have gotten intrigued by HyperCard, then Director/Authorware, then Flash, then HTML, then...
Or more simply – $25K (+ tax) put in a savings account will earn about enough interest to pay for a $100/month AI subscription indefinitely. And at the end of it you still have the $25K.
This is the real answer.

Unless you need privacy for your inference this instant, paying for credits can get 80 to 90 percent of people everything they need.

Of course if you do need that privacy, then forking the $25K over to Apple is a no brainer.

I don't need privacy, so it would be financially imprudent for me to spend 20 grand on such a machine. But I have a financial management client who does need such privacy, and if I get more fully engaged with them then I would be able to justify getting a loaded Mac.
Why is this a no brainer?

There are both cheaper and faster options out there.

Not 'more simply', there are basically zero savings accounts that are going to net you a 5%+ interest rate to give you that $100 a month. And that $25k becomes less valuable over time. $25k is now only worth $19k because inflation.
Money market/treasuries (even ETF like SGOV) gets pretty close to 5% when typical savings rate is a bit under

If treasuries “fail” we have a different class of problem.

Rates are around 3.5% right now before taxes.
