Xeon E5-4620 Vs Xeon X5675 Vs 2670? for Crunch.

[FireFox]

Hi every one.
As the title says E5-4620 Vs X5675.
I would like to know which one would be the better option.

Cheers.

I'd say E5-4620, more threads/cores newer tech higher IPC? Though this is my humble opinion only I have no experience with either chip from which to base it!

I would say the same.
I know the Xeon X5675 because I have a few, but the E5-4620 it's something new for me.

I wouldn't go with a E5-4xxx CPU unless you plan on running four of them. These CPUs have enough QPI links to do 4 socket systems. I would suggest a E5-2xxx series CPU, for less cost you'll get better performance but will still retain dual CPU capability, or maybe even a E5-1xxx CPU if you're not planning on going DP or QP.

The E5-2670 would be a far better choice and shouldn't cost more.

for less cost

Well i never said prices.

E5-2670

It uses 115 W, no in my plans.

E5-2660 then if you want to hold on to the 95-watt TDP. Still higher boost clocks than the E5-4620. As I said before, unless you're planning on going QP, it's better to go with a E5-2xxx CPU but I would still go with a SB-EP or IVB-EP CPU in the E5-2xxx series over the X5675.

 

[CAPSLOCKSTUCK]

i am not voting in this poll because i am Xually biased.

ES- 2660 is a good option and ok for blades too.

 

[Heaven7]

but the E5-4620 it's something new for me.

Same here. I agree completely with @Aquinus , E5-4xxx CPUs for QP systems only, if you can afford them. Better performance per buck with two DP systems.

I know the Xeon X5675 because I have a few

Same here. Let 'em crunch!

Worried about those additional 20 watts? Turn off your monitor.

Agreed and noted for future upgrades. For now though, I'm happy with what I've got to crunch on and can afford - hence my vote.

Monitors are always turned off

As i have said before it's something new for me and because i can get those Xeons very cheap i would like to buy at least one in order test power consumption performance and so on, let's say to have some fun with it and to learn something new.

 

[Cybrnook2002]

I got a 2620v3 and a 2670v3 if your interested. I can only use one..... (both under $400)

I would browse a bit more. I'm seeing the E5-2660 on fleabay for as low as 150 USD which is a great price for a 8c/16t part. If I didn't have to repair the car, I would have considered investing in two of those.

My E5-2680v1 dually and my E5-2650v2 dually both produce more than double what my X5675 does. Each of the duallies get 18.1PPD (average), where the X5675 gets around 5.5K PPD (average). I haven't looked at the exact specs, but assuming it's just a matter of 4P CPUs vs. 2P CPUs, then the new generation should still be an improvement over the last.

As long as you can get the parts cheap, they're worth it. If you have to shell out for retail, then no.

Since (iirc) BOINC scales pretty linearly with cores and clock speeds, just as a really rough estimation of multi-threaded horsepower, I usually just take the number of cores multiplied by the clock speed to get sort of a "total GHz" rating. the E5-4620 and X5675 both clock close to each other at 20.8 and 20.82 respectively. Here's a detailed "on paper" comparison between both processors. I highly recommend poking through Anandtech's review of the Sandy Bridge-EP architecture too.

If you can get either for the same price, I'd definitely lean towards the E5-4620 for the improved architecture (and as others have said, the E5-2660 over the 4620 unless you're going quad socket).

that is exactly the sum i used, i used a pencil and paper.

How are you seeing the E5-4620 @ 90 euros? The cheapest available here is $500 each for non-ES ones

Ebay

Note: I bought it but not in Germany.

I found a Quad socket motherboard for that Xeon but i don't have a clue what kind psu i should use for it.

 

[[Ion]]

Still that's really cheap. $500 was the Ebay price here too....

 

[mstenholm]

ES and 150 Euros. More than 10 avail.

I would like to buy 3 more, I just need to find out what kind of psu I need for the board.

150€ it's not that bad.

 

[FireFox]

I would suggest a E5-2xxx series CPU

Does anyone own a 2670?
I need some advice.

Cheers.
