Actually, I think I know what the problem is. The 820M is one of those card with a boost feature and on Windows the driver will boost until the GPU temperature reaches 70C, then the driver will start downclocking the GPU. On Linux this feature seems to be missing, the driver never downlocks and the card will boost until either powerclamp starts injecting insane amounts of idle time or (if you have disabled powerclamp) the temperature reach the thermal limit (~96C).
