You can build a Phenom machine with ECC RAM. Heck, you can make an Athlon computer with ECC RAM.
What does that have to do with anything? They use Xeon processors, not Athlon or Phenom. Although, the rumors say they may start using AMD processors in at least some of their computers, that isn't the case at the moment.
It has to do that most of the fault with pricing lies in the choice of Xeon.
Also, intel processors, last I checked anyway, tend to perform better than current-gen AMD processors, so if they ever used them, I would expect them to be in low end MBPs, MacBooks, and Mac Minis, not Mac Pros.
What guarantee do we have that this computer will last longer or perform better? None. You have to buy that guarantee with Applecare, similar to a warranty you buy from anyone else.
$3700 for a six core machine, with 4 ram slots - 3 of them taken up with 1 GB chips is very expensive.
$2500 for a 2.8 Ghz 4 core machine with 3 GB of Ram is insulting.
I will concede that the dual quads and dual hex cores are competitive, but still - six 1 GB ram chips in a $5000 computer? Bah. At least make it 3 x 2GB chips so I feel a little less violated.
Either Apple doesn't want to be competitive at the high end or it can't be competitive at the high end.
The single CPU hexacore and the double CPU quadcore are equally priced (well, more or less). Which one should I get?
If I am doing video encoding would the One 3.33GHz 6-Core Intel Xeon Westmere or the Two 2.4GHz Quad-Core Intel Xeon Westmere (8 cores) be better. I am guessing the 6-core just becuase of the higher base processing speed and because video encoding using something like x264 wouldn't use all the cores anyway correct?
That's easy. The 6 core will be faster for most applications. Where the 8 core will overtake the 6 core is when you have applications that require a lot of processing and utilize ALL 8 cores.
Jut set x264 to use 24 threads on the 12 core. You're better off buying a PCI hardware encoder if you need to do a lot of encoding.
All these comparisons that show Apple dead-on with pricing parity when considering Dell, HP, etc dual Xeon boxes and this is what you come up with?
The pros who really need big time calculation for video, rendering, or science aren't interested in ANY desktop. Instead, they will buy multiple, relatively inexpensive semi-generic rack mount servers from a very competitive market. These will be stuck in a dark server room where they belong. They don't need costly video cards because they don't need video output. They don't need a shiny deco-modern enclosure because no one but the system administrator is going to see them. And they don't need any Mac OS/X features other than its Unix underpinnings, and those can be provided for free by the Ubuntu 64 bit Server distribution.
And what facts do you have to support this?
Yes, but, people who buy workstations would most likely not configure their computers like that. People who buy workstations most likely will need the extra power of a dual hexacore computer and the reliability of Xeon + ECC RAM, which, does cost more.
EDIT: Also, it's a mac, and with that comes great customer support, a truckload of apps in Mac OS X that make your life easier, and a case that's designed to be easy to open and mess with, so IMO, you get what you pay for, if your market is workstation-class computers.
Uh, how about 33 years in the computer profession? Does that work for you?
