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.

Is there a 64bit version of OS X for the Intel platform? I didn't think there was, considering that until now all of the Intel Macs have only had 32bit processors.kelmon - Thursday, August 17, 2006 - link
Depends on what you mean by 64-bit. OS X has, I believe, had a 64-bit UNIX layer since 10.3 (I don't think it was introduced with 10.4) but the only applications that can take advantage of this are command-line tools. Leopard will introduce 64-bit everywhere but I'm still struggling to find a reason why that will impact me in a good way. That said, the new Mac will have a 64-bit processor so that I can feel future-proof.Pirks - Wednesday, August 16, 2006 - link
Good question. I don't know, maybe OS X on those Mac Pros is patched to 64-bit or something.. if not than I should shut up and wait till Leopard.Snuffalufagus - Wednesday, August 16, 2006 - link
it should factor in at least a 25% - 35% discount code on the Dell :).I have never bought anything off the Dell site without getting a substantial discount from a current promotion.

Does Dell offer 25-35% off for Dell Precision Workstation?MrPIppy - Wednesday, August 16, 2006 - link
The last generation of Power Mac G5s also had dual GigE ports: http://www.apple.com/powermac/specs.html">Apple's G5 specs pageOne difference though, the G5s (and the GigE G4s before them) used Broadcom 57xx chips for Ethernet, while the Mac Pro now uses an Intel 8254x chip.

But what is so good about Macs? Why would I want a Mac instead of a PC? What can a Mac offer me that a PC can't? I don't like trolling, but I seriously am asking these questions and want to know what the answers are.phaxmohdem - Wednesday, August 16, 2006 - link
I used to be a mac hater because All the macs I've ever used truely were Pieces of $h!t. Old single cpu G4 towers with no Hard Drive Space or RAM, and way too much student crap spread on them. HOWEVER recently I had the pleasure of using a REAL mac (Quad G5) for a video project, and it made me think of macs a little differently. Plenty fast, and stable. My biggest problems were learning all the new Mac hot keys and keyboard shortcuts.. but once you master those you'll fly on the mac. (Some of Macs shortcuts still seem pretty stupid and complex to me though).However I serioualy don't understand the keyboard and mouse that Apple gives their cusotomers... The new mighty mouse is an improvement, but still an uncomfortable POS to me. Ditto for the mushy fugly keyboard that is standard. I've found that a proper Logitech (or similar) Kybd/Mouse combo makes the mac experience feel 10x better. (One more side-gripe... OS X does not have adjustments for mouse acceleration, and for me the stock acceleration speeds are wretched and piss me off... Hopefully this is something to be updated in the next release of the OS)
So, moral of my story is... if you're going to Mac it up, do it right with proper input devices and some decent specs, and you'll have an enjoyable experience under OS X. I personally still choose Windows for its versatility w/ software and hardware... but to each his own.

Agree. I find it somewhat ironic that the only MS products I really like are their keyboards, mice, and joysticks. What's particularily maddening is that Apple used to, years ago, make the best keyboard money could buy. Seriously, solid as a rock and typing feel you'd kill for. Now they peddle crap that looks nice. Not good.timelag - Thursday, August 17, 2006 - link
Apple used to, years ago, make the best keyboard money could buy.Ah yes, the extended keyboard II. Better even than the famous IBM and Sun keyboards of yore. If it weren't for my Kinesis (the One True ergo keyboard), I'd be using mine through an ADB to USB connector.
