I checked 2 AMD G34 systems. For points I used the last 7 day average to figure a per day amount. Systems are both running Linux. Here are the results.

Workstation 1: ~60,000 ppd 325 watts (multiplied by 24 for watt/hours) = 7.69 ppw/h (points per watt/hour)

Workstation 2: ~150,000 ppd 620 watts (multiplied by 24 for watt/hours) = 10.0 ppw/h (points per watt/hour)

Workstation 1 is currently having some sort of issue as it doesn't seem to be doing as much work as it's capable of. I've been working on finding out the cause.

Here is a video showing these two system up close and personal. Happy new year! - Ryan

Very cool Ryan ! Outstanding.

Cool video. My dual X5670's @2.93 are doing around 77000 ppd. My i4930k @3.9 is doing around 60000. Waiting on intel to release the 8 core haswell around summer time.

I remember Bearcat posting power consumption figures for that machine before somewhere...can't remember the number.

The 4930k system is probably the most efficient though, probably only using about 200 watts for the entire system.

Generally speaking, the most efficient systems are going to be the ones that have the most non-overclocked cores and have the least amount of extra devices (graphics cards/hard disks/etc.)

Just looked at my UPS's, the dually is at 260 out with no GPU installed and the hex is at 175 out. The hex is OC to 3.9Ghz and has a 7950 GPU in it. Monitors were off though when I looked. Also, the dually has 4 hard drives and an ssd whereas the hex has 1 ssd and 1 hard drive.
