dunno about amd, but with a 750ti, i was getting 4+mega(no extreme oc)

When I used to mine qubit using sph-sgminer performance fluctuated +-5% if memory serves. I would have to go great lengths to exceed 1MH on my hardware.
I couldn't observe any such variation in the profiler (~1%, perhaps lower), I'd say there's a good chance this is due to stop-n-wait work dispatch. It would be interesting to see if those are somehow chipset related as it is my understanding transfer latency is higher on AMx chips.

Considering the hardware/drivers you use I'm not surprised. Previous message relates to an old build of sgminer-sph only.
