Modern CPU

(moderation:
I realized my Phenom II came out 4 years ago. It still does not feel slow, but what are the more modern ones doing? One of my CasA took 400,000 where its valid wingmate took only 40,000, is that more to do with the task than cpu? I have some others that were much shorter.
Intel is much faster, but much more expensive. AMD has more cores. If you were going new in a year or so, where do they all stand?

My CasA units take about 20,000 seconds (running 3 CPU and 3 iGPU tasks at once).
I got a Intel i7-4770K clocked at 4GHz
Found this 2012 comparison of CPUs GFLOP capacity. Not quite up to date but gives you a hint perhaps: http://www.tomshardware.com/charts/cpu-charts-2012/-15-SiSoftware-Sandra-2012-SP4c-Pro,3145.html

400,000s seems very slow for a Phenom II X4 820, are you sure about that? The valid CasA's listed for your host seem to all be about 38,000s which is pretty good. I get about 15,000s (from an i3770) through to ~50,000s (for an E6700 3.2GHz).

Ah yes, I should pay attention to the fact that I have two computers running! Those were the Via 1.5ghz runs. 10x slower even with more than half the clock speed. Uses something like 12 watts for a single core where the AMD has 4 cores using 95.
Anyway, it still seems like what you'd want for running tasks here are somewhat different than you would want for a gaming pc or a server. Without actually buying the chip, what would you look for in a review? Gflops like listed above? They don't specify per core though, and most projects aren't multithreaded.
Hi Chris, The gflop

Hi Chris,
The gflop reference from above was only 1 of 21 benchmark and application tests that were run for all the processors. Of course the processor rankings change somewhat depending on what feature was being exercised and how each was being tested. Overall the review has to be considered as just a starting point.
The real-world proof of how these processors perform for E@H can be seen in the top hosts list. With a little digging you can find out how the results are being achieved, as it does take a lot of work to get top performance - it's not just plug and play. This listing also allows you to compare your hardware to others with the same/similar configuration. Perhaps you will spot something that is being done, that with a bit of tweaking and testing on your own equipment might result in higher productivity if that is your goal.

I have an Athlon, a Phenom

I have an Athlon, a Phenom and two Phenom IIs with a variety of speeds all quad core obviously. I have tried making sense of their RACs and while generally related to clock the rest of the variations are beyond me and I sort of know what I am about. Whatever else is on the motherboard appears to causing the differences like memory buss speed and refresh cycles and more.
Benchmarks are generally worthless unless you do everything being measured by every benchmark in equal amounts. Over the decades AMD has put an emphasis on number crunching, BOINC is number crunching, I stick with AMD. I have had two Intel machines which were not noticeably or measurably better.
I can only say if you are in the right ballpark don't lose sleep over it. Get a cheap CUDA card and that is about all there is to do.
I just recently started

I just recently started crunching on my L5420 Core 2 processor that I have installed in my server. The CasA tasks run in approximately 25,000 seconds. I picked up these processors for $40 a piece on E-bay back in 2011. I see these processors going for as low $25 today. I temporarily took out the second processor a while back but plan to reinstall it.
The performance for the price I paid seems decent overall and the max TDP is rated by Intel at 50w. A server board is needed but because this CPU requires is an older generation socket, I have been able to find used Supermicro boards for as low as $40.
The newer processor generations like the Intel 2nd - 4th generation i7s are faster but also more expensive and power hungry.
