The following graph clearly illustrates that A10-6700T 45W TDP Richland reaches Tcase Max after approximately 35 second and the processor reduces the power(gets slower) in order to keep it within the TDP rating of 45W and bellow Tcase Max temperature.
On the other hand, the Kaveri 45W TDP A8-7600 keeps the same power for the duration of the benchmark run. That indicates that the processor didnt reach the Tcase Max thermal limit and was able to use more power thus higher performance and higher power usage.
So people for the last time, TDP is not the max power usage. You never should compare the TDP rating with CPU power consumption.
Those graphs make it look like the CPU is either running at Max power or idle. That is, there is never an intermediate level, which is what I would expect if it throttled back to some lower intermediate clock when the Max temp was exceeded. Even after a fairly long period, the power usage never comes back up, as I would expect after the CPU cools off somewhat. Or does it just mean the job is finished when the power usage drops back to idle levels.
