Duo vs Xenon

[Rider01]

New to the forums, so I will ask this question:

You guys seem to know a lot about the Duo processor so the question is:

Do you think that the Duo overclocked is faster than dual Xenon processors?

I am interested because I am considering rebuilding my Game system and am at a point where I have to make the decision on Duo or Xenon processors. Duo would be cheaper by half but is it faster..............

Xenon's are bright headlights often available in cars. What you was meant to say was Xeon.

Anyway, what are you comparing exactly? What Xeon's and what Core 2 Duo's?

Will you be changing the motherboard?

Also, how much power do you need exactly? Dual Xeons could mean 8 cores, do you really need that much? Might be wiser just going for a Q6600, QX6700/6800 quad core CPU instead using 1 S775 socket.

Xeon motherboards won't have as much features (well if you don't count SCSI) as enthusiast S775 boards. Also proper Xeon boards are S771 vs S775 for the Core 2 Duo series and *some* Xeon's.

Give us some more details to work on.

Xeon, sorry for misspelling it, I should know better.

I have a ASUS P4B with a 478 socket, 2.4 GHz 533 FSB processor. I am considering a major upgrade of a new MB and processor(s). The machine is used primarly for gaming, some graphics work occationally.

I am considering either the Xeon or Duo Core2. If I go with the Xeon single processor to start (I can upgrade to two processors at a later time). The MB's I have been looking at are dual processor boards, the three I am looking at all have a max of 8 gig of ram. The two Duo boards only support 2 gig of ram. (And share that ram with the video.)

I really don't care if the board has embeded sound, video, ect because I always go with expansion cards for those items.

So if the Duo Core 2 runs at 3 Ghz and the Xeon (have to go back and re-read the spec's) is running at 3 GHz, which is faster? Which will perform better under heavy workload?

I am guessing the Xeon will have a better through put than the Duo, but I do not have any experence with the Duo processor as of yet.

Thanks for your time.

Athlon 64 X2 = Dual-core Socket 939 Opteron
Core 2 Duo = LGA 775 Xeon

There might be a couple quad-core Xeons with 1333FSB.. (not sure) but other than that they are identical, meaning same performance under same configuration.

Hi Rider,

there are two flavors of Xeon: socket 775, and socket 771.

Socket 771 Xeons are used in pairs--the high end Macintosh now uses two socket 771 Xeons on an Intel 5000X chipset motherboard. When you use the 771s, you will need to buy FB-DIMM memory modules. Also, you will need to get a whopping power supply to run the 771s, the memory, and so on.

A core 2 Duo is probably going to be a better choice for you--two fast cores, so it's like having a dual CPU system without the extra power and space requirements.

Here are some socket 775 Core 2 Duos and Xeons compared: all have at least 4MB of shared cache.

Depending on your price range, this system that Tom's Hardware put together might be a good starting reference point:

For a game machine, balance is good--i.e. enough good memory, a good graphics card, and a good CPU like the 6600.

Anandtech's recent guide:

I recommend you get a good quality name brand power supply: PC Power and Cooling, Seasonic, Corsair 620, etc. Skimping in this area is a bad idea.

Memory: Kingston, Crucial, Corsair, Micron, Patriot. Get 2 x 1GB matched pair at least.

HTH,
