Server Processors

This is for work, not for me. I'm doing some research on multiprocessor setups in server configuration and I thought I might ask here first.

Performance wise, would any quad configuration of Xeon E5 46XX v2 beat out any dual configuration of Xeon E5 - 26XX v2 or is there an equilibrium point between the two setups?

For instance would a 4x Xeon E5-4603 v2 2.20GHz, 10M Cache, 4 Core be equivalent in performance to a 2x
Xeon E5-2660 2.20GHz, 20M Cache, 8Core. Or is one of these setups far superior to the other?

I'm not familiar with servers, or multiprocessor setups in general. Just looking for a cut-off in terms of the benefits of 4 cpu setups vs 2 cpu setups.

Thanks for any input, gents!
 
Hey guys, Just going to give this thread a bump just in case any server/multiprocessor guru's weren't on when I posted the thread a couple days ago.

Just trying to lean some more :) thanks guys!
 
hey mate, they dont really like when you bump a thread for advice, keep it in mind ^^ though i cant really help ya with your question ;s might want to check some reviews/comparisons if they're out there?

How are you going to be configuring the server? Are you going to make it into a stand alone server or make it into a ESX Host?
 
I can understand that, it wasn't my intention to upset anyone with the bump.

I tried looking for some comparisons, but I couldn't find anything technical. There aren't a lot of use cases that really promote an the need for that kind of comparison anyway, a vast majority of people don't need any kind of multi-processor setup.

I was curious if there was anyone on the forum that had experience with this.

It's stand alone. It's meant for calculations, and will be a 2U unit. Basically a rack mounted server.

If I'm looking at this correctly to which I think I am...

The Xeon E5-2660 v2 is running 10cores so if you are going to use 2x of these you will have 20cores.

The E5-4603 v2 runs only 4 cores with 4x so you are only going to end up with 16cores.

On paper the Xeon E5-2660 v2 is better but also does have a higher cost compared with the newer E5-4603.

I picked the wrong one for my example... That's my fault.

Here is my hypothetical question:

Configuration 1: 4 processors. Each processor has 4 cores (64 threads total). Each processor has 10M of Cache.
Configuration 2: 2 processors. Each processor has 8 cores (64 threads total). Each processor has 20M of Cache.

If both setups are running at the same frequency (say 2.2 GHz), and have the same amount of memory available to them, will they be equivalent in performance?

Would it be better, overall, to have more threads for calculations or more processors (all other variables being equal)?
