Power Consumption

The big advantage of Westmere is power consumption. If we compare last year’s Mac Pro with the GeForce GT 120 idle power consumption is actually lower than the new Westmere system thanks to the Radeon HD 5770 drawing more power at idle. If you look at the 2009 Mac Pro with a GeForce GTX 285 however, the 5770/2010 Mac Pro has a significant idle power advantage.

Idle Power

The same is true under load, although the GPU plays less of a role in our Cinebench render test for load power. The Mac Pro we’re testing here is clocked much lower than our 2009 Mac Pro, which explains some of the power advantage but not all of it.

Load Power - Cinebench 11.5

We’ve been tracking Mac power consumption in OS X vs. Windows for quite a while now. I decided to see how power consumption changed under Boot Camp. As expected, idle power was a bit higher while load power consumption was identical:

Power Consumption Comparison
Mac Pro (Mid-2010) Mac OS X 10.6.4 Windows 7 x64
Idle 144W 159W
Load (Cinebench 11.5) 256W 253W

The 15W difference in idle power usage is significant, but honestly it matters a lot less in a system like the Mac Pro than a mini or MacBook Pro. The Cinebench scores are identical under both OSes in case you were wondering. This wasn't always true, Apple has significantly improved OS X performance with 10.6.x vs Leopard.

    I understand including a nice case, as the mac case is quality. But you're right, $250 is a bit steep. There are plenty of less expensive cases that are just as nice, and some real budget cases that would be serviceable.

    If I had the money, I'd buy one of these in a second. Apple rules. In today's world though, budget is important and PC beats out Apple heartily on the mid-powered PC market. I own both Mac and Pc (side by side, my two babies) and I love them both dearly. If I had to choose a brand new super powered computer though, I'd have to go with the Mac because of the OS.

    Maybe I'm missing something here but a quick search on newegg showed a $700 difference in the price of the graphics cards, maybe thats why the dell is so expensive?

    The Mac IS a PC. If you mean a Windows system, then say that.

    Didn't see it mentioned in the article, so I'm assuming no, but I want to double-check: Does the Mac Pro support 3x1 Eyefinity setup?

    Also, it's a shame that they're not offering the Eyefinity 5 or 6 models as an option.

    Really appreciate the honest comparison to the custom built, but the Dell T5500 isn't exactly comparable. It's easy to say "other than the graphics card" but seriously:

    Apple's ATI Radeon HD 5770 1GB - $249 from Apple or $125 from Newegg

    Dell's ATI FirePro V8700 1GB - $860 from Newegg

    It's a tough comparison to make if you really want to dive into it. The FirePro price premium is due largely to the driver work and it's tough to tell what equivalent driver work (if any) Apple has done in OS X. Either way, it does change things quite a bit and I've updated the text to reflect that there is an Apple tax that's just hidden by the GPU cost differential.

    Thanks for the comment :)

    Take care,

    Thanks for the update, it truly is a tough comparison.

    I think an even greater concern with both the Dell and Apple tax is that both are using what might be considered as "commodity components"; Apple certainly would be using Foxconn, and I do not know of Dell's core supplier. The point being, these components do not have the same reputation of quality and performance as those used in the custom built.

    The extent of the tax goes even further...

    Not sure how you managed to reach the $324 number you published in the edit in the article. The cheapest fireprov8700 I can find costs 600 flat (ebay buy it now). The difference is at least $500 once you deduct the street costs of the packaged gpu.

    To me the "why a Mac Pro" is I have been afraid to build myself a solid dual socket PC workstation class machine for Pro 3D modeling, rendering and compositing with Maya and Final Cut Pro. But now I am very used to some pro Apple and none Apple software and happy. So in my case my current 2.8 octacore has been very, very reliable. For graphic design I agree it gets more difficult every time to justify a dual socket machine like a Mac Pro. Why 8-12 core for illustrator or even Photoshop?, Get the fastest quadcore PC for this. But also is a matter of personal preference.

    The Mac Pro is not the fastest machine out there but not either the most expensive or exotic hardware as there are usually faster PC hardware and more specific software options and features. But, if you like me are using specific multithreaded Pro software with decent performance and like OSX, then the Mac Pro is very solid. No Mac Pro has died on me yet, they are easy to upgrade for the most common features, work very well out of the box, is reliable, offers dual socket options and no Apple tax on comparable Dell or similar workstations.

    On the other hand, even I use the Mac Pro all day long I builded a SFF quad core PC and this is the machine I am going to upgrade this year. The PC is "my back up" machine but the one that goes outside with me when I need performance, and also one very useful rendering machine.

    By the way Anand, very good article! I enjoyed very much reading through the lines, not defensive at all, not too long and I learned on some features and coments. At least to my experience as a Mac Pro user from the beginning and even from the days of the G5s.
