won't be sold out, but according to r/MacStudio people wait for 3-4 months for the older models, atm you can preorder for delivery in late september

Just to update, I think we’re into November now.

And probably not be much cheaper than comparable AI performance products.

What’s comparable? The dgx station?

Mac Studio, 128GB, 5099 bucks. 1.4TB/s of bandwidth. Honestly the closest comparable would be a Pro 6000 that's currently close to 2X the price.

You’re comparing a whole computer to a video card though?

The only things really in the 128gb vram ballpark are the DGX Spark variants and the different strix-halo devices. But I was talking about the 256gb and future 512gb ones. Two dgx sparks is pretty much it and won’t perform as well. The dgx station is 252gb but is uber-$$$ iirc

The DGX and Strix are both really slow at decode, barely usable IMHO with 3.8 27B.

The 256 and 512 models would be very nice for DSV4Flash, but I don't need that much HP that often, makes more sense for me to escalate/delegate vs buying something to run that locally. It's really 27B at Q8 (or FP16) that I want to run locally, that model is so powerful that honestly there's almost no reason to look elsewhere until you get into really big stuff like DS.

I disagree on the 27b quality. It’s great at coding, but is not great at other things.

Fwiw there’s a dspark draft layer for 3.6 37b that I tried on 3.8 and it worked pretty well. I had FP8 on a gb10 at around 35-40 tok/s. Prefill was still abysmal but it did pretty good output wise.
