Apple's Mac Pro - A True PowerMac Successor

Power Consumption
According to Apple, the biggest reason for its switch to Intel processors was the chipmaker's future roadmap and its promise for lower power consumption and better performance per watt.
We've already seen how much smaller the Xeon heatsinks are in the Mac Pro compared to the older G5 units, and we've talked about how much quieter the Mac Pro is than its predecessor, but what about power consumption at the wall?
At idle, the Mac Pro with four cores uses no more power than the dual processor PowerMac G5. Of course at idle, each core's cache is being powered down, the CPU is being underclocked, and all of Intel's famed power management is hard at work.
Under load, running the multithreaded CineBench test, the Mac Pro consumes significantly less power than the PowerMac G5 even when running with all four cores enabled.
And just to save you from doing the math, here's a graph of performance per watt when running the same CineBench test:
At 65nm, the Xeons in the Mac Pro are obviously more efficient than the 90nm PowerPC G5, but the performance per watt these new parts offer is tremendous.

Could you show me how to get Dell to take $149 off for the monitor? Whenever I try to configure it if I select the "No Monitor" option it lists a cost of $0, meaning I don't gain or lose anything.The Dell protection plan is truly enterprise class however the point of the comparison was to look at things from a purely hardware/cost of components perspective, which is how these Mac vs. PC price comparisons are usually done. Once you go above and beyond that then you get into this slippery slope argument of how much you should tack on for the price of being able to run OS X, etc...
Take care,
Anand

The "they" was referring to Apple namely at the WWDC6, no offence Anand. The option is given under the Medium and Large business section, but your point is well taken that exact price is impossible in that section.Keep up the good reports,
Kyle

I was under the impression that Cinebench had very light memory usage. It looks to me that what will make or break Woodcrest's "power efficiency" is going to be FBDIMM power so perhaps loading up the ram will paint slightly different numbers...TamarinMonkey - Wednesday, August 16, 2006 - link
Now that we can run both OSX and XP on the same hardware, I'd be interested to see some of the benchmarks run on both OSs and see how they do. Any plans to do this in a future article?~Tam~

I am pretty sure this has been done, and OSX has been found to be lacking, especially in 3d games. The speed advantage of PC over MAC was not that Intel/AMD were so much faster than IBM G4, then G5, but the OS and drivers are much finer tuned.Tegeril - Wednesday, August 16, 2006 - link
It was definitely not so much about the OS/Drivers being finer tuned in regards to 3D gaming. It was definitely a DirectX versus OpenGL issue.psychobriggsy - Thursday, August 17, 2006 - link
More specifically, Apple's OpenGL implementation on PowerPC was/is severely lacking.I wonder if the Intel Mac OS X drivers are better - i.e., the ATI/Nvidia drivers ported to Mac OS X.

I just played WoW last night on my Quadro 4500-equiped Mac Pro. An ATI version should be similar. I was in a 40 man raid for my guild. This thing screams in OS X. I get 30-40 fps in a crowded IF, 50-100 fps flying, and I peaked at 135 fps looking at the sky. All at 1920x1200. The drivers sure have improved and I think are better on intel. I have a 2.3 Ghz dual core G5 and this is twice as fast even thought the G5 had a 7800 GT card. Oh - and I never noticed the fans spin up during the raid even though I had low sound volume.Rumor has it that OpenGL will be much improved when it goes multithreaded in 10.4.8. We will see. :)

I forgot to mention: the Mac Pro loaded the WoW AQ40 instance in about 2 seconds! Faster even the second time. I can't express how impressed I am with this machine.As a side note, I used Office in Rosetta, and it is as fast as my G5. Maybe 4GB of RAM helps here but I was worried after reading Anands' report.

Please use XP x64 benchmarks as well, since it's uberinteresting to see how both 64-bit OSes from MS and Apple compete. XP 32-bit is okay, but a bit boring.
