AMD FirePro V4800 & FirePro V7800
The Phoronix Test Suite also recorded some other test metrics for us when we were running Unigine Heaven a second time.
As a percentage, the FirePro V7800 had the highest fan speed compared to the other Evergreen workstation graphics cards, but still all of the graphics cards were very quiet during testing. In fact, their noise was always much lower compared to the dual AMD Opteron heatsinks.
The FirePro V4800 GPU core had an average operating temperature while running Unigine Heaven of 60°C, which was 5°C less than the FirePro V5800 and 3°C less than the dual-slot FirePro V8800. However, the FirePro V7800 had the highest temperature overall with an average temperature of 66°C.
The GPU usage while running Unigine Heaven was about the same between all of the cards (being fully maxed out) except for the wonderful-performing V8800 that wasn't quite fully utilized with an average of 83% utilization.
