Westmere X5670 2.93 Ghz X2
----------------------------------------ATI 6950 GPU time: 220 CPU time 100.683 Westmere X5650 2.66 Ghz X2 ATI 5670 GPU time: 456 CPU time: 146.266 Weird but boinc shows about 3:30 after completion but adding up the gpu and cpu for my 6950, looks more like above 5 minutes.

Think y'all need to report the kernel time [the time on the GPU], as a power-card in a meek computer could give substantial false impressions. A quick hit go-oogle: http://www.phoronix.com/scan.php?page=news_item&px=MTEyNTI . Kernel time 150-155s, CPU time around 220s. Time as reported as elapsed in BOINC time is approximately CPU time. Do you think that with faster CPU (and same GPU) would elapsed time (which is kind of WU turnaround time) be shorter? I can also notice that there is almost a minute lost in total for initializing a work on GPU and (probably) getting the results back from GPU? |

Your CPU time would be a little faster, depending on what CPU you use. Have noticed the lost time too. Am seeing a fluctuation of total crunch time of around 30 seconds or so between GPU wu's.

Intel 2600K overclocked to 4400MHz
ATI 7950 with stock OC 900MHz/1250MHz one wu done in 1min 16sec of that time, from what I see in GPU-Z graph, GPU is active 33sec at 75-80% load |
