I have crossfired a discrete HD 6670 2GB DDR3 card with an AMD A8-3800 APU. Both CCC and GPU-Z confirm active crossfire (represented as HD 6690D2).
However, I have tested GPU usage across both these cards with Skyrim, Fallout: New Vegas, and Half Life: EP2. In every instance, the APU's integrated graphics usage reveals little to no GPU contribution. Kombuster shows sporadic, split second spikes from the 6650D ranging from 33% to 100% every 5 to 10 seconds. AMD System Monitor show 3% to 8% integrated usage. GPU-Z shows 0% to 11%. Alternatively, the 6670 discrete card shows 90% to 100% usage.
According to the former results, I do not believe the integrated HD 6550D is contributing to its AFR (alternate frame rendering) responsibility, as judged by the disparity of the GPU usages between the cards. I am left to wonder what exactly it's doing, if anything.
Does anyone have any information, insight, or contradictory evidence to my results and subsequent conclusion?
(note: the monitor cable is connected to the mobo).
