So no four channel memory.
And from what I have read, it looks like the xeon 3500s only have one QPI link, just like the i7. If you find documentation otherwise, I'll stand corrected.
I'm looking at the entire family, not just the low end chip. but I grant that there isn't too much difference there.
So the only differences are ECC and using a bit less power, neither of which are going to make a difference in real world performance - the two machines will run a given app the same, the user is just paying twice as much for ECC and to use a bit less power. Oh, and for twice the price you get the ability to use LESS ram.
ECC is very important to more than a few users, so don't denigrate that. Lower power makes for a cooler machine, a quieter machine, and less total power use. This is important where there are installations of a number of them.
Funny, with a ram limit lower than an $899 dell and about the same performance, it sure looks like the Mac "Pro" quad IS a consumer tower. Apple is just charging double for it.
We don't yet know if that 8 GB is a hard limit, or just marketing. As I pointed out earlier, Apple has done this many times in the past. PC manufacturers are quick to tout every new feature and capacity increase. Apple is much more conservative.
And I'm not asking for a consumer machine, I AM asking for a pro machine. I just don't define "pro" as a machine built with sturdier parts but consumer level performance (or worse).
Well, performance certainly won't be worse. But many institutions that buy these machines are not looking for ultimate performance, or they would buy the more expensive machines, but rather reliability, which these machines do provide.
I'd be happy with a consumer machine at a consumer price. Or with a pro machine at a pro price. Apple doesn't seem to hit either market.[quote]
While I agree with the first sentence, I don't agree with the last.
Either way, it is bought for someone to sit in front of it and run apps. You really think that the majority of these buyers are willing to pay twice as much for "workstation parts" but don't care if performance is no better than a machine half the price?
Not all workstations have people sitting in front of them. Many are used for rendering, or other purposes, headless. It's not likely the low end machine will be used for that, but the dual machines certainly will.
But don't "very few" people really need a workstation class machine in the first place? You insist there are enough people who need ECC and whatever else allegedly makes this a Workstation...yet you don't seem to think that that is the same group that may need more than 8 gigs?
You don;t get points for that, because as I said, most of these machines are bought by companies or other institutions. Price is less of a problem for them, because the competition is at the same price level.
As far as the RAM goes, we're back to the "we don't yet know". So let's drop that until we do, ok? Even so, not every use needs that much RAM. That's a myth.
When it comes to ECC ram and the other excuses for the pricing, this machine is aimed at the small group of Professionals who can't settle for a consumer machine and insist on only the best.
But when it comes to ram limitations, then the market for this machine suddenly becomes those guys who really don't need anything that special and can settle for something LESS than what some cheap consumer boxes are offering?
I don't see how that's not a contradiction.[/quote}
PLEASE, drop the RAM argument for now.
And for the record, I am one of those who can take advantage of more than eight gigs of ram, I have more than that in my current machine already.
I'm dying to see your response when the benchmarks are out and the i7 and xeon 3500 have negligible differences at the same clock speed. ECC isn't going to boost performance, is it? Nor lower power use?
So what IS going to make the 3500 faster than the i7 at the same clock speed?
I'm dying to see yours as well.
