Being so tiny but so powerfull could we expect a moderate energy bill?

It’s mostly small because they’ve come up with a really clever cooling system and reduced internal expansion, not because there’s all that much less power-hungry stuff in the out of the box configuration. The lack of HDDs should save a little power, but a the 12 core next-gen Xeon model is supposed to have a TDP in the 115-130W range; a FirePro W10000 GPU can pull 375W and this machine can be configured with two of them. So a maxed out model under full load could conceivably pull over 900W in a worst case scenario.
But keep in mind, modern hardware has pretty impressive power management features; it could easily run under 400W with workloads that can’t simultaneously max out every core and both GPUs, which most can’t, and considerably lower than that if you’re just browsing the web or whatever. And, obviously, not everyone will buy a maxed-out system.

No worries, Jeremy. You know that hole in top of the Mac Pro? Just throw in a banana peel, some stale beer and the can –you’re good to go!

The other thing about all of this new Solid State tech internally is that in the “off” state, they use almost no power at all. It is one of the reasons that iOS devices last as long as they do.
Spinning disks consume power as does the logic board that is continually pinging them to stay awake and available ( we all should have turned our sleep settings to OFF on your NLE machine) needs to then be cooled more so the fan runs- it is a never ending cycle.
I was told that the power consumption could be as much as 1/4 of the previous model, mainly do to Apple’s technological zeal for longer battery life on the iDevices.

While the Tube is tiny, it achieves a lot of that “smallness” by offloading features that still have to exist. If you need hard drive storage, those drives will now exist in external cases and will require their own cooling and power. It is quite possible that after adding the external peripherals you will need to make your system work, each with it’s own redundant independent cooling and power supply, you will have a larger overall power bill than before. A lot will depend on what your peripheral needs will be.

I disagree Herb, without FW or eSata, most will start moving to USB3 and TB for external devices, all of them newer and far more energy efficient than what has been on the market, one focus on externals being that are forced to run cooler externally than if placed inside the machine.
I really think people are missing the point about the new MacPro, most people I know that call themselves “power users” virtually never touch the inner workings of a computer once they buy it. We are talking less than 5% of “power users” ever change graphics cards or swap out drives. Look how many people talking specs here on the Cow are asking about iMac’s for editing and that started LONG BEFORE the Tube was announced this week.
In a tapeless world, I do not see ( nor do I have) the need for an internal card any longer. My TBT storage is head and shoulders faster than my 4G fibre network. I connect to it now via a TBT Fiber adaptor to reach my servers, instead of having an HBA sucking power and generating heat 24hrs a day.
I believe the big difference here in that PCIe cards internally in your computer are drawing massive amounts of power and generating extreme levels of heat where you are using them or not.
Whereas I do not see very many people at all that just leave ever single peripheral they have connected to a machine on an running in the same manner if they are not using them.

But doesn’t the fact that there are two on-board (so to speak), high-end, graphics cards mean that there’s still going to be a considerable amount of heat generated? I have an Nvidia card in my older workstation, and when I’m rendering, the fan kicks in and goes until the render is over. It appears that the Mac Pro “chimney” is passive cooling (although I don’t know this for sure), so what moves the air (aside from convection) when this thing is cranking? They didn’t put two graphics cards in there to just look good…

Hi
Big fan on top:

[Paul Dickin] “Big fan on top:”
Yup,
and a vertical inclosure is going to naturally act as a “chimney” to make cooling much easier than it is to force horizontally driven air across a surface when the expelled heat from the board interacts with the circulating air it wants to naturally rise.gary adcock
