A sample of 20 BRP4 tasks from after averaged 1475 seconds. Two similar samples from before came in at 1479 and 1446 seconds/task. Standard deviations for the sets ranged from 123 to 157 seconds; so I'm almost certain the variation I've seen is just noise.
Thanks for your comments. I presume your before was 7.0.28 as well.
I had a look thru a few days of your data and I see a huge range in the numbers - 1221-2995. And this is with overlooking several in the 4000-6000 range which are atypical. So an average of 20 might not be providing a true picture. The stdevs on my 50 sample data sets are averaging about 3% of the average value.
My numbers are holding (subject to hw malfunctions) at the lower values and it's now been about 12 days.

Yes to previously 7.0.28; my really high GPU numbers all involve boinc deciding to unsleep the GPU while I'm gaming and managing not to crash the task before I notice the framerate hit (the other half of the time I discover it crashed out a few dozen BRP4s before giving up and grabbing a less demanding primegrid/collatz task)
I've looked on the performance of my Radeon HD 7850 with 2 GB VRAM and a GPU clock set to 1050MHZ (overclocked in ccc).
Running solely 1 WU the GPU is around 45% used. With 2 WU in paralell GPU usage is around 90%.
Measured with 80 WU I've finished so far the average GPU time in seconds is 1330.
The values vary from 700s to 2000s but mostly around 1300s.
Temperature of GPU is ~50°C.
Card is running in combination with an and 64GB RAM
I ordered a pair of Intel 64 GB SLC SSDs for my Linux AMD rigs. One system already had an Intel 520 but I wanted to move the BOINC data and log files over to the new SSD to save the flash life of the 520. The other system was on a spindle previously and had a 120mm fan to keep the disk cool. Since switching this system to SSD, I have seen a reduction in runtime of approximately 20 seconds per task per GPU. The system power consumption is down by approximately 15w from removing the hard disk and fan. These changes are not very significant but every bit helps.
Yes that is a bit longer than the BRP4's on a GeForce 660
I loaded several on my 660Ti SC and my other hosts but they are still running the BRP4's they have so I haven't actually ran a BRP5 yet......now I wish I didn't load so many before trying just a couple on each host.
I'm not seeing any speedup

I'm not seeing any speedup from 7.0.64

Anyone try the new nVidia driver?

I am running 320.18 on my i5-3570 with GT640 abd GTX660 it was a ho-hum
upgrade nothing changed , loading runtimes or power consumption, on Einstein.
of course the BRP5's were anything but ho-hum.
Upgrade was from 310.70 or 310.90 I have both directories in my NVIDIA/displaydrivers
RE: I am running 320.18 on

YOW I just looked at your 660 running the BRP5's and saw a couple of these.

Thanks for the info Tom
Those long times are from my

Those long times are from my GT640 not the GTX660, But that is running two
at a time.
The GT640 runtime for BRP4 was 8,543.83 two at a time so approx 11 - 1
BRP5 vs BRP4
