Anybody knows why Apple does not offer a MacPro with one 3.2GHz Quad-Core Xeon? This option
is doable as the chip is available. Applications that I run do not take advantage of 8 cores.
Apple does not want to have a quad-core running at a higher clock speed than an octo-core. And Apple wants their slower octo-core options available.
 
But Apple is a big customer. They should get more discount than an individual person. The Intel price lists on the net are probably for those who buy in small quantities (perhaps only one cpu). Is there a list for big customers?

Intel price lists are always for quantities of 1000. Apple is a big customer (and not only a _big_ customer, they are buying a very high percentage of expensive processors, and they are very good for marketing, so you can assume they are treated well), so they will likely get these chips cheaper than a box maker buying just 1000 chips. The relative prices will be the same. If you pay more for one fast processor than for two slow ones, then Apple (or Dell, or HP) pay more for 100,000 fast processors than for 200,000 slow ones.
 
Sounds like a good idea. In fact, volume discounts are pretty common in most industries. Unfortunately, it seems AMD will file a lawsuit every time Intel offers anyone a discount for any reason. I'm exaggerating, of course....

Volume discounts are fine. intel can say "I'll give you a better price if you buy 100,000 chips", that's totally legal. Intel cannot say "I'll give you a better price if your company doesn't use any AMD chips". That would be anti-competitive and therefore illegal.
 
For OP

Why should they?

If you don't need the power of the 8 cores then you won't miss the difference between the 2.8GHz and 3.2GHZ, running over 4 cores.
 
yes, but...

I heard about the advice from Intel to developers. However, most current applications do not take advantage on multi-core (especially 8 cores) systems. Until such highly multi-thread programs are widely available, I would rather Apple offers a MacPro with one 3.2GHz Quad-Core Xeon or an Extreme CPU.

We're never going to get software written to take advantage of multi-core systems until we have a greater amount of multi-core systems out there.

Multi-core is the future, and the hardware has to lead the way.

Besides the obviously easier expansion, is there really a reason to get a single core mac pro over an iMac?

That's not really true currently. There are still alot of applications that could benefit from that extra 14% processing power that can't use more than 4 cores.

I prefer matte screen but Apple does not offer such an option anymore. Also, noise from iMac's fan is sometime annoying. Besides, I need more than 4GB RAM.

That is exactly the point I am trying to make.

You "need" more than four gigs of ram, but you don't want to pay for a pro machine?

I am going to buy the next generation MacPro when it comes out the next few months. I am going to get 16, 32GB or more memory. I don't want to invest on an expensive duo CPUs system and FBDIMM right now because applications I run do not use 8-cores and nobody knows if Apple will use FBDIMM on the next generation MacPro. By the time Snow Leopard and more applications that take advantage of 8-cores are out, the cost of such duo CPUs systems and RAM may be lowered. If Apple offers a 3.2GHz single CPU MacPro now, I will buy it for my dad and share the computer with him.

By the way, how many cores do Leopard and the 64-bit version of Vista Ultimate use?

Because they know people will buy the 2-processor version if that's the only option!
