You're going to frighten the children. You know, the ones who are going to be servicing the nMP.
I know this is a bit of an old thread, but....
Still doing my research on the nMP and CAD/BIM software. I found this on the Soildworks site and remembered this thread.
Interesting info on the W series FirePro cards. Certainly seem to fit the overall requirement for 4k output, but what was particularly interesting was the power consumptions.
If the D300 ~ to the W5000 then the 450w is certainly capable! I believe this would equate to the least noise, most thermally efficient design quoted at the October event.
Then assuming MVC's 12 core assumption is right and the W8000 is somewhere near the D700 the 130+2x189=508w so a move upto a 650w supply probably wouldn't hot air gun the paint from the walls or burst your ear drums!
Thoughts?

Lol - seriously though I do wonder what the max fan throughput is going to be from the nMP with twin d700's. I can visualize a fountain of dust from the desk top sucked up and thrown over the user and the monitors when doing big rendering jobs
Spotlessly clean desks will be required and outside Cupertino that's going to be tricky
I don't get the gloom & doom fear about the new MP's becoming like a blow torch. A small machine dissipating 600w would impact the room environment the exact same way a large one would with the same 600w. In other words put your hand behind the exhaust fans of your old Mac Pro while it is cranked up to eleven and you can feel quite warm air coming out of it. The new MP's design will be more efficient so it doesn't get quite as hot but it's much less likely to be as loud because of the simplified internal air-path so its going to be quieter no doubt. Less obstructions and clear path for the air flow means less turbulence and quieter operation. Go drive in a classic car with giant chrome brick sideview mirrors slamming the air at highway speeds and compare to a modern streamlined car mirror. Moving through the air at identical speeds doesn't produce nearly the same dB reading because of the poor aerodynamics of the older designs.
The large singular fan with tuned blades moving slower than smaller more numerous fans would need coupled with what I mentioned above doesn't mean the new MP will be all that much cooler, you can't change the physics, but you can try to get the acoustics on your side by carefully keeping the air calm and uniform.
Anyone care to answer this yet?
The phrase isn't there to sell something, it's there for a reason.
I'm not sure what the confusion is all about. You clearly will not be able to use both the GPUs and the CPU at full tilt at once without throttling on the 12 core + D700 at least if the power/heat budget is 450w. Believe it or not the laws of physics do apply in Cuperino. Not a big surprise though. Performance is not the primary design intent of this machine.
The new Mac Pro seems to have placed emphasis on compactness, beauty, silence, and power savings at the cost of PCIe slots, memory slots, internal drive bays, and a sufficient power supply to run everything at full tilt with plenty of headroom left over.
Do these compromising design choices seem like they were for a workstation? Because to me these choices seem like they were designing for a very powerful Mac Mini.

I can't wait to see what the real Power numbers are but when people talk about dissipating hundreds of watts - let alone 400W+ I start thinking that is just enormous!! Four 100W light bulb kind of BTU's....
This is the data from a 12 core MP. Are we seriously talking almost 2X of that?? As I stated --- can't wait to see what the real answer is when these are in the wild....
Mac Pro (Mid 2010)
12-core 2.66GHz configuration: Two 2.66GHz 6-Core Intel Xeon "Westmere" processor, 6GB memory (six 1GB 1333MHz DDR3 ECC DIMMs), 1 TB Serial ATA 3 Gb/s 7200-rpm hard drive, 18x double-layer SuperDrive, ATI Radeon HD 5770 with 1GB of GDDR5 memory
Power Consumption Thermal Output
Idle---- CPU Max---- Idle--- CPU Max
145W----- 285 W -------- 494 BTU/h 972 BTU/h

Ehhh!
I was actually sharing some hopefully more realistic PSU requirements for the W series cards that I found, that's all. When you go back a couple of pages the projected numbers were getting rather high in criticism of the proposed only known 450w supply and hinting at throttling to make it all work.
If these numbers do equate to the D series requirements then things look better aligned to a 650w supply for the max'd out machine. But we are still waiting to see!

Another thing to add to this discussion which I posted in another thread is the fact that the Xeon CPU has a TJMax of 70C before throttling begins.. and the ATI cards have either a 100-105c limit. This will be interesting if Apple can prevent throttling unlike their macbook pros. Having 2 components with different TJ's all being on the same heatsink seems like a bad idea.. under a full load GPU scenario, the temps alone would cause the CPU to go into a throttle state even while idle...can't wait to see how that works lol
When exactly does all this throttling of MBP's occur? I am transcoding a video (rMBP 2.6) right not using every core at near 100%, my fan is screaming, but the CPU is steady at 3.00GHZ and 38W. That's not throttling, it a 2.6Ghz proc with a boost of 3.6 which I do see if using a single core. The video just finished and the fan went quiet, proc down to 6.61W and freq is steady at 1.2-1.5Ghz.
Seems like it works exactly as designed. Of course YMMV.
Apple does more research on stretching power usage than pretty much any other maker and in nearly case has set the bar and been copied. I'm not terribly worried.

That huge heat sink is never going to rise to anything like the temperate of the GPU or CPU dies themselves. Maybe you could get it close eventually if you disabled thermal shutdown systems and operated your Mac Pro in a vacuum chamber. Don't do that
Depending on what CPU model you have, it's not hitting full turbo boost if it's at 3GHz. You should be getting 3.6 on all four cores. What is your CPU model? (TOTALLY OFF TOPIC SORRY GUYS haha)
Intel's Power Gadget - Great tool!

I don't think you would ever see 3.6 with all 4 cores going. I was actually surprised to see 3.0. I would expect something closer to base freq with 780% CPU usage reported. Mine runs about 3.4 using two cores and that is right in line with my expectations.
Citation? Not because I don't trust you, but if anyone is starting to take apart a Mac Pro, I'd be very interested in all the details.
Thanks very much. I tried it out on my 2012 Mini 2.6 i7. I ran a Handbrake encode, the processor frequency jumped right to 3.4 and pretty much stayed there (it briefly dropped to 3.2) even with the fans ramped up high. What does that mean? Are all four cores going at 3.4 (there's only one line on the graph)? Activity Monitor said Handbrake was around 770% CPU use.
The specs have been listed for the 4 and 6 core. It's likely the 8 core or 12 core has the same power supply, but I was wondering if that has actually been verified as the post implied.
yeah, I guess it's open to interpretation as to how the specs are listed.. to me, the 450w power is a single row spanning both columns of the chart.. and both columns have 8&12 cores listed in them.
dunno, just seems to make more sense to have one psu which works for all configurations.
