CPU question relating to Boinc

post #1 of 11
Thread Starter 
So I have a question on relative performance of cpu's in boinc. I need to purchase a 2011 cpu and was wondering --

in the same cpu family (ivy bridge ep) would I get better performance from a 8C 2.8mhz or a 10C 2.5mhz processor?

Or should I just realize that the sandy bridge E5-2670 @ 65 dollars is just to good of a deal and use that.

Since the majority of BOINC projects are not multi-core the CPU with the larger core count will generally be a better bet.  If you could clock the 8C CPU high enough (if it wasn't a locked down Xeon) then you might be able to overcome the core deficiency with the higher clock speed.  For the price, the E5-2670 is pretty tough to beat.   You can put together a few complete E5-2670 systems for the cost of one E5-2670 v2 processor. :D

Those prices are hard to beat. I upgraded all of my work servers and I have a left over 2011 MB. I know that I should get the cheap cpu's but I am bored with them already smile.gif I think I will do the smart thing and stay bored wink.gif

It's a 2p v1/v2 mother board so that won't work. I did the prudent thing and ordered 2 e5-2670's for $125

Where do you get them at that price?

Went up $5 since I purchased yesterday. Looks like I payed $129, must have had a brain cramp smile.gif The price fluctuates but is mostly trending down.

I like the ASRock EP2C602-4L/D16 for messing around. You can do 2x gpu with it comfortably and it has been stable. It is a SSI EEB board, so make sure it fits in your case.
If you need ATX size the Asus Z9PA-D8 is ok. It really only fits 1 gpu (comfortably) but it will fit in most cases. I purchase most of my boards "open box" so I payed a little less than what Newegg/Amazon is selling them for.

For production work I usually use the Supermicro X9DR7-TF+ but it is way overkill for consumer use. Plus it is very limited in what cases it can fit in.

I was looking at the core count and multiplying that by the Speed and comparing the numbers between 2011 v1 and v3 Intel chips with WCG. The numbers were very close with the v3 chips being marginally faster.

The biggest difference is power consumption.
