No, keep a close look at the clocks. Latest driver all have a directly influence between temperature and core clocks. The higher the temperature, the lower the clock. When you do a benchmark, the GPU heats up, the core clocks goes down. If you do only a single hash, you propably had a GPU idling for a while or at least long enough it can cool down. This gets even worse with GTX 10xx series because of the aggressive core clock throttling
