I am trying to optimize our K80 for multiple video encoding schemes, but it seems like we are not getting the performance out of the K80 that we should.
- Why does the ‘AutoBoost’ only goto a maximum of 562MHz on the pclk?
- Why does the encoder utilization not goto 100% whenever it is being used? (I have seen several encodes where it maxes out at 80% and it still takes 20minutes to process a video.)
- When testing the same file; we found that a 780-Ti was able to process a video at 346fps, and the K80 was only able to achieve 197fps.
Would we be further ahead to downgrade our driver and switch to CUDA processing?
