Are the neural engines actually used for anything, to anyone's knowledge? Edit: Apparently in iPhones, they are used for FaceID.

Would something like huggingface transformers ever be able to support this? Or is it best fit to just use the GPU.

I'm cross posting a question I had from the Mac Studio thread (currently unanswered). ---- Mac Pro scale up? How is this going to scale up to a Mac Pro, especially related to RAM? The Ultra caps at 128 GB of RAM (which isn't much for video editing, especially given that the GPU uses the system RAM). Today's Mac Pro goes up to 1.5TB (and has dedicated video RAM above this). If the Mac Pro is say, 4 Ultra's stacked tog…

I think some of this can be guessed from the SoC codenames https://en.wikipedia.org/wiki/List_of_Apple_codenames M1 Max is Jade C-Die => 64GB M1 Ultra is Jade 2C-Die => 128GB There is a still unreleased SoC called Jade 4C-Die =>256GB So I think that's the most we'll see this generation, unless they somehow add (much slower) slotted RAM If they were to double the max RAM on M2 Pro/Max (Rhodes Chop / Rhodes 1C), which…

How is slotted RAM slower? 6400Mhz DIMM exists. This would match the specs of the RAM on the M1 Max. Even octa-channel has been done before so the memory bus would have the exact same width, latency and clock frequency.

Looks like all the people saying "just start fusing those M1 CPU's into bigger ones" were right, that's basically what they did here (fused two M1 Max'es together). And since the presenter mentioned the Mac Pro would come on another day, I wonder if they'll just do 4x M1 Max for that.

>I wonder if they'll just do 4x M1 Max for that. They'll be running out of names for that thing. M1 Ultra II would be lame, so M1 Extreme? M1 Steve?

> M1 Steve

That would be the funniest thing Apple has done in years. I totally support the idea.

Does it mine bitcoin well?

Not Bitcoin but Ethereum

M1 Pro -> 5.8 MH/s, with a 17w draw, means $12.82 a month profit. I don't imagine the M1 Ultra is too much better, maybe 20 MH/s at absolute most, but we'll see. It definitely won't be as economical as 3070 or 3080 FE cards at current profitability levels.

Right. Still riding gains from the node shrink and on package memory.

Could AMD/Intel follow suit and package memory as an additional layer of cache? I worry that we are being dazzled by the performance at the cost of more integration and less freedom.

Is it actually more powerful than a top of the line threadripper[0] or is that not a "personal computer" CPU by this definition? I feel like 64 cores would beat 20 on some workloads even if the 20 were way faster in single core performance.

Adobe Photoshop, Premiere etc make use of it for scene detection, content aware fill, "neural filters" and so on

I like "X1" way more than "M2 Extreme".

Earlier quoted context omitted.

> But surely the GPU things can't be real? The GPU in the M1 Ultra beats the top-of-the-line Nvidia? Dubious. https://www.pcgamer.com/apple-m1-max-nvidia-rtx-3080-perform...

From the article: > Apple even says its new GPU is a match for Nvidia's RTX 3080 mobile chip, though you'll have to take Apple's word for it on that one. We've also reached out to Nvidia to see what it might have to say on the matter. > RTX 3080 mobile chip > mobile chip There's a 50%[1] (!) difference with mobile and non-mobile versions of the chip. So that's hardly a deal breaker. [1] https://www.videocardbenchmark…

The "mobile" scam in GPUs is terrible. Nvidia flat out lies about Mobile performance by giving misleading product names (same as the desktop names).
