Some results data that is very lacking in detail but may give users a feel for the direction this may be going in regards card efficiency:

I would be curious to know if anyone had seen an improvement in the duration estimates over the past 6-8 hours now that these statistics should be much more accurate. This should hopefully address some of the issues with non-gpu workunits being very badly estimated and excessive downloads occurring. The estimates for my 2 machines without an app_info are much better now. That's not said well enough. They're fantastic now. Within 15%. Good job, Kevin!  |

So far this takes no account of CPU performance but I will endeavor to add info as I get it Very nice OldChap. If you wanna add a column more about efficiency: How about Watts/WU? Edit: E.g. My i7-2600 pulls 120W from the socket with 8 cores running 100% (only CPU-tasks). When a task is replaced by HCC GPU on my ATI 7770 it needs 30W more.

Anyone who wants to add to this info then all I need is card type and total run time in mins and secs. add cpu type and speed as well please.
----------------------------------------watts??? anyone that uses a Kill a Watt and can provide more details??? Do you have thoughts on how best to show that Crystal Pellet? |

Watts isn't a good idea due to the discrepancy between machines. It's more than about what kind of CPU and GPU you use, but the efficiency of the power supply and motherboard is at powering these devices. If you want power consumption, you should simply get official numbers on power consumption.
----------------------------------------Running a 7950 OCd to 1100Mhz core and 1575MHz memory with a 4Ghz FX-8120. ~40 work units per hour while also x264 encoding. Not 100% confirmed that this is the max speed since I am x264 encoding as well (with some high 10, 10-bit depth, placebo, subme 11, etc. extreme settings). Update: After setting x264 to use four cores, and having the 7950 process four work units with one core each at 85% max GPU utilization, 46.2 seconds per work unit completed (3 minutes and 5 seconds divided by four work units), therefore 78 work units per hour. GPU is only used half the time, so I will now up to 8 work units at the same time. Update2: With one core doing x264, and the other 7 processing 8 GPU work units, GPU usage is 92% for 3 minutes, followed by 1.5 minutes idle waiting for CPU. Overall about 290 seconds to complete 8 work units, which is at one work unit completed every 36.25 seconds, or 99.31 work units per hour. I'm certain that if you pause a couple work units and resume them you can increase the potential max work units per hour by keeping the GPU busy, as whenever the GPU is running only half of a single core is being used per work unit on my processor.

I agree with mmstick that just the watts a machine pulls isn't a good figure, but how many watts a machine extra pulls when running HCC on the GPU. This should be measured carefully and over a longer period, because the GPU is idling half of the time due to start and end CPU-usage by the tasks. In my edit in my former post I mentioned 30W, but this is when the GPU is really busy. |

Kevin,
Yes, my run time estimates are much more accurate now. Thanks for all your effort. CaptainJack |

Hi nanoprobe
Many thanks for your config file. On my I7 with an ATI 7970 it is taking about 2 minutes to complete each work unit running the 4 together which works out at 30 seconds per work unit  Fantastic and thanks once again Lufty |

On my Q9550 and ATI 6950 at default clocks, it takes 3 minutes and 30 seconds

Don't think you can trust what boinc is showing for crunch time. I monitored a few and saw after the completion time hit zero, it stayed on that wu for a little bit more time. Boinc shows 3 min 30 sec (varies per wu) but when I add the total of GPU time and CPU time, its around 5 minutes.
