I bet you can build an AMD system that beats this handily and costs half as much.

And the power consumption?
- sudosysgen 4y ago
  Do you actually care about power consumption in a desktop computer under very heavy workload? By the way, the M1 Ultra has a 370W power supply, so really the question is do you really care about the difference between 300 and 400 watts in this use case?

Complete non-sequitur, you could put a 1.5kw power supply on an R7 5700G or an i3, that doesn't mean it pulls 1.5kw. you also should be able to express this without using the flamebait style, that is not appropriate or welcomed on this site. Instead of "by the way...." you can simply say "the M1 Ultra pulls 370W so ...." (or you could, if that were true).

      There is no easy way to know how much the Mac Studio can pull without using a wall meter. We know that reported power consumption is inaccurate on M1 devices, from Anadtech's testing of the M1 Max, and I doubt it's very different on the Mac Studio. In any case, the difference is not going to be much. As far as heating a room, really, I can assure you that you will barely notice 100W. There are screens that will use more power than that (such as, amongst others, the XDR screen). I say this as someone who lived with a 900W power hog of a computer in places where temperature hits 42 in shade.

    Er, machines in the M1 Ultra class do not have 400 watt power supplies. The 2019 Mac pro that it's compared to (with 28 cores) has a 1.4Kw power supply. A 12900K has a max TDP (for the chip, not including ram) of 210 watts, and loses on geekbench5 to the M1 ultra by 1/3rd or so. To get closer you'll need a i9 or threadripper and systems with either of those typically need quite large power supplies and still have a small fraction of the memory bandwidth.

    The power supply is rate that high because it is expected to supply power to several USB-C ports. It looks like the max power consumption of the Mac Studio is 215w. https://support.apple.com/en-us/HT213100 https://support.apple.com/en-us/HT213100

      I don't know about the Mac Studio, but the Macbook Pro can exceed its stated power consumption limit. USB-C is a very plausible way, but I doubt it has over 100W of USB-C PD budget, and PSU included is 370W continuous, so it still has headroom for devices.

        but I doubt it has over 100W of USB-C PD budget The Studio Ultra has six Thunderbolt 4 ports. Each port is required to deliver at least 15W by the TB4 standard, so that’s already 90W. Add some budget for the USB-A ports and you are near 100W for power delivery. (Probably not much over that though.)

  Is an irrelevant metric, like battery life, when doing scientific computation.

    Performance per watt is a pretty big metric. Personally the fact they didn’t produce Linux drivers for these things is baffling. It would just make more people buy them. So what if they don’t run macOS? I would buy a M1 air tomorrow if they published Linux drivers for the full stack.
    - macintux 4y ago
      I have to think they’re developer- and supply-constrained. They’ll make up those sales once others have cracked the problem.

        I don't believe it, honestly. I would gamble that it's because helping Linux grow doesn't financially benefit them, now or in the future. And that, to me at least, feels quite a bit more likely from Apple.

        > Personally the fact they didn’t produce Linux drivers for these things is baffling. Followed by > helping Linux grow doesn't financially benefit them, now or in the future Is a bit perplexing. Why are you baffled? Opportunity cost is a very real thing. Apple would probably be better served by developing Windows drivers, if they were going to take developers away from macOS drivers.

Can you? how much will you charge to build one for me? Do you offer warranty support?
- diffeomorphism 4y ago
  Not OP, but sure why not. Just buy, say, a $4000 workstation with support from one of the usual vendors and sell it to you for $4500. Btw most of that price is for certification for industry software. Does the Mac have that? If not, it is just immediately not an option.

Not with 800GB/sec of memory bandwidth. Or even the 440GB/sec of memory bandwidth available to the CPUs. Sure if you are cache friendly enough and you get enough Zen3 or Intel cores you can win, but you end up spending a fair chunk of change, getting less memory bandwidth, and for a clear win you often need to spend more, like say getting a Lenovo Threadripper (and they have a exclusive rights to the chip for 6 months or something).
