Xeon vs overclocked i7, who would win?

post #1 of 13
Thread Starter 
I'm doing some consulting for a company and they are going to buy me a workstation for the onsite work.

My initial reccomondation is the fastest dell workstation money can buy. A t5500, Quad Core Intel Xeon Processor X5677, 3.46GHz, 2gb of 1333 ram (Dell's prices on ram are just stupid, I'll buy 12gb from newegg.) Even if I don't go with Dell and built the thing, I don't see any Xeon boards that are overclockable.

At home I have an Asus P6x58d and an i7 930. I have it running at 3.8ghz and the ram at 1800 (I think there's more room to fiddle too - by the ram's spec it should run faster. Win7 score is 7.5/7.9/6.8/6.8/6.9

I figure if I'm buying for them I can build a machine and get the fastest i7 avail (the 3.33?) then overclock the pee out of it.

The most intensive task I'm running is finite element analysis (FEA) and it's strictly a single core task so there is no advantage to 6 or 8 core processors, a quad will be fine. This task can take anything from minutes to hours depending on the complexity of the models.

Bang for the buck, the i7 clearly smokes the Xeon (I have about a $1k in mine +the graphics card), but this project is critical path (we only have 80 days to complete it) so the cost of the machine isn't really that important.

So, what I'm wondering is who would win? The overclocked i7 or the Xeon?

As I understand it, the Xeon chips and i7 chips are almost identical, save that the Xeon chips have 2 QPIs rather than the i7s 1 QPI. This only makes a difference in mulit-processor setups because the second QPI for the Xeon is for interprocessor communication. If you are only planning on using one chip then you would be better off going with the i7. Also most boards that support the i7 will work with the Xeon chips, but it would be best to check the manufacturer's website

The Xeon is mention is 32nm. The i7s are 45nm. That's a big difference - look at Sandy Bridge.

Why not 2600k, btw?

not all i7's are 45nm. the 970 and 980 are 32nm.

and as much of a fan of overclocking i may be. i still think critical systems should never be overclocked. it introduces way to many unknowns for critical computation.

if you need single threaded performance, then id go with a 960. not sure if they still make them, but it has a core speed of 3.2GHZ

That's really not relevant to this post. We're comparing Quad-core CPUs.

But, again, why does any of this matter when Sandy Bridge wipes the floor with all of them?

No, it doesnt. Not the 980x.

ok, sandy it is
2600k
ASUS P8P67 PRO
CORSAIR DOMINATOR GT DDR3 2000
OCZ RevoDrive X2
and a quadro 4000
Probably go with a coolermaster 800w silent pro, I have two of the 600s and they work well.

and I'm at $2k now (plus a display), that's a lot less.

now, what cpu cooler for max oc'ing
which cases are most popular and QUIET

Thanks for all the help.

I would go to my sticky, if I were you (link in my sig), and make sure the P8P67 Pro is for you. There are other motherboards that are very similar.

I also think the RevoDriveX2 is a waste. The next generation of SSDs is upon us. A single Vertex 3 would kill a RevoDriveX2 (essentially two-to-four Vertex 2s).

I don't know anything about Quadro cards, except that they are the same physical card as their Geforce counterparts and are only more expensive because of the drivers they support. In which case, it was possible to flash the Geforce to a Quadro in the BIOS and get the same performance.

Oh, and I don't how much the Coolermaster 800w costs, but you can have the Silverstone 1000w single-rail for 150$, and it's far, far better.

In regards to the cooler, everyone here will tell you to get a Rasa Kit, but if you don't want to deal with the hassle, any top end air-cooler will do, or even an H70.
