Edit: ^^^^ It is quite a big bump up. Jaguar CPUs are usually 1.5Ghz (1 in tablets) so at 1.8 the heat out put should be quite a lot higher than normal. Does explain why it is shown to use 140W. The last few Mhz take a lot more voltage and the Intel CPUs at 3.X Ghz are far from their limit because they're so mobile focused.I subscribed to this thread just to keep track of this post.
