7870 : 2.0 minutes @ 75% load and then 1 minute with only CPU load.
----------------------------------------GPU Temp stays around 46°C on load. CPU @ 43°C and Mainboard Temp sensor @ 34°C. Case Fans are at lowest voltage. [Edit 1 times, last edit by [AF>HFR]Thomas at Nov 6, 2012 2:44:08 PM] |

Very interesting. Hyperthreading off speeds up the GPU. Only if you're running a number of GPU tasks equal to or less than the number of CPU cores available.
In 1969 I took an oath to defend and protect the U S Constitution against all enemies, both foreign and Domestic. There was no expiration date.

I am running XFX R7870 with 12 instances on a 980X @3.9 with 6G Ram @1600. The HT tends to spread the WU finish time around so that they are all not getting done at the same time (HT cores minimally slower). Keeps temps down and Max use of GPU and CPU a bit lower but more constant.
