You can eventualy use the link provided by Khato
to evaluate the TDP in function of frequencies ,
you ll see that going from to 10W to 3W you ll need
to reduce frequency substancialy.
FWIW, I thought Clover Trail was surprisingly zippy on my Asus ME400C tablet. Definitely faster than Tegra 3 on Surface RT (except for graphics). It was fantastic for basic usage, really. No complaints. I could pretty easily get 7-8 hours of battery life out of the tablet.
And yet you initially claim that "At 50 or 100°C a TDP of 5W is 5W in both case" only to then backtrack and say that it's a relatively small effect once an explanation of temperature's effect upon power consumption is provided.
It probably is 5W in both cases. 4.8W in one case and 5.2W in another case, both would round to 5W. I would be very interested in seeing what the actual effect is, on this end of the curve, where Vcc is at or under 1.0V.

That's effectively the same point I was trying to make - TDP only gives a rough indication of power consumption and is dependent upon other conditions. Just because a part is labeled at 10W TDP doesn't mean that it's going to consume 10W under load.
Quite interesting how the A6-1450 with a maximum clock frequency of 1.4 Ghz CPU/400 Mhz GPU has a physics score of 17126 while Anandtech's review of the A4-5000 - http://www.anandtech.com/show/6974/amd-kabini-review/4 - which should always be running at 1.5 Ghz CPU/500 Mhz GPU only score 16812. Similarly the GPU running at 80% the frequency achieved 94.4% of the graphics score at 24574 vs 26019. Could be that drivers have markedly improved since the review?
