For those that don't know, the new 64-Bit compatible Xeon processors are out with the prescott core. Range is from 2.8 to 3.6 Ghz with 800 Mhz FSB. L2 Cache at 1 MB. Motherboards I have seen so far have PCI-Express and DDR2...so the question is...

Should we wait, or should we move on it now?

BTW, NewEgg only has 2.8 and 3.0, CDW has up to 3.4, and Buy.com has everything

Thanks, and can't wait to hear your replies
 
Are they still using Socket 602 or whatever the Xeons use?

I'd say forget about the Xeons unless you do SMP.

If you want a 64-bit Intel chip, wait for the Pentium 4 'F' chips.

It's a Socket 604 chip just like the last Xeon chips. However, it's nearly useless because the new Xeons require a new chipset to support the new FSB frequency. Besides, the DC-DC regulators on the old motherboards were probably not up to the task of powering these new Noconas anyways.

Yes, but the new chipset has also been released, and like I said, the motherboards are out there...

And also, are you saying that a 660 watt PSU wouldn't be enough?

I wasn't talking to you; that's why I didn't specifically quote you. I was just making it clear that the new Xeons aren't compatible with current motherboards, unlike Socket 478 Prescotts and motherboards intended for Northwoods.

And no, where did I ever mention anything about power supplies? I plainly stated that the DC-DC regulators on the motherboards are probably inadequate for Nocona Xeons. Normally I wouldn't go off on a tangent about a theoretical condition like this, but when you put words in my mouth after I clearly stated my claims, I get a little frustrated.

On a side note, do you even realize that there is a sophisticated DC-DC converter circuit on the motherboard which converts the input supply of 12 volts to a ~1 volt high amperage supply for the motherboard? Delivering power to the CPU requires the cooperation of both the motherboard and power supply circuitry.
 
No, sorry, wasn't trying to put words in your mouth....sorry

Thanks for the info though...I thought DC-DC Converter dealt eith the PSU
 
There are DC-DC converters in most power supplies, though you'd have to open up the enclosure to notice them. After the AC voltage is rectified (converted) to a rough DC voltage, it is the job of DC-DC regulators to convert that voltage to regulated 3.3, 5, and 12 volt lines.

But no, I meant on the motherboard. It might also interest you that videocards also have one or more DC-DC converters onboard.

I love this forum....

Ya learn something new every day.
 
Generally called MOSFETs? Or is that something different? (Since we're already drowning in n00bishness anyway...)
 
A MOSFET is a type of transistor. MOSFETs are often used in power circuits because they can switch very fast and can handles lots of current at the same time. It's just one piece of the DC regulator circuit.
 
Are you an Electrical Engineer?

That Xeon idea sounds good, but I would just wait to see what intel brings out with their "F-series".
 
Or you can learn this stuff on the web...if you've made it this far and don't know what a Metal Oxide Semiconductor Field Effect Transistor is.....hmmm....

Oh well...

So, is it the processor that's the issue, or is it the motherboards and chipsets that makes these Nocona's something to stay away from?
 
No, there's nothing wrong with the chips. What xonik and the others were saying is that the older Xeon Socket 604 motherboards won't be able to use the Nocona Xeons; you'll have to get one of the new Xeon motherboards.

Personally, I'd stay away from these Xeons because of price concerns, and because the Pentium 4 F chips will come out soon, which are the consumer version of these Nocona Xeons.
 
Pack Rat 24:

"Stay away from?" Are you looking to buy a Nocona Xeon based system? I heard you use the word "we" earlier on.

...because if you are, let's discuss your performance, reliability, and budget needs and help you decide how this processor compares.
 
Well, I'd be building the system for heavy duty video editing...I was thinking the dual 3.6's would last a nice long time in the current market...

I know it's a little expensive, but the power would be good to have while encoding, etc, etc.
 
xonik said:
Well, if one media encoding benchmark is any indication of Xeon 3.6 performance compared to Opteron Model 250, I'd say that the Opteron would be the better choice:

Then again, we could wait for AnandTech's upcoming review that directly compares the Opteron Model 250 with the Xeon 3.6 in 2P configurations.

Only thing is that we probably wouldn't be encoding with WMP 9

And also, what happened to Intel always performing better at this sort of thing?
 
application still is a major factor though, even with the same codec, different front ends can swith the favor between intel and AMD (as [H] shows in their encoding benchmarks)
