Synes lige jeg ville tilf�je f�lgende taget fra maccentrals forum:

"The 400 and 500MHz PowerBooks shipped with a 7410, which has a very low
typical power rating of 5.3W at 500MHz. The 550 and 667MHz PowerBooks
shipped with a 7440, which has a much higher typical rating of 13.4W at
700MHz. 

The only three 74xx chips that support an L3 cache are the 7450, 7451
and 7455, so one of them must be in the new PowerBooks. The 7450 and
7451 seem to be almost identical, certainly in their power figures.
They're both rated at 14.5W typical at 667MHz. The 7455 has typical
power rating of 17W at 800MHz, but there's also a low power version
rated at 10.3W typical at 733MHz, and limited to a maximum clock
frequency of 800MHz. 

I haven't seen any documentation hinting to low power versions of the
7450/7451, so I'm guessing that the new PowerBooks use the low power
7455. The upper limit of 800MHz is a solid hint to that effect. 

So the CPU probably doesn't use considerably less power than previous
models. Considering the Radeon 7500 and the L3 cache, you'd expect a
temperature increase. Maybe they've come up with a better heatsink
design, but it seems doubtful this would make all the difference. I'd be
interested to know if I've missed any chip variants in my brief search.

Hvis det er sandt (nu er der da ligefrem effekt i tal) tyder det da p�
at 800'eren er koldere end 667'eren.

N� men ellers tak for udredningen... jeg synes bare det er m�rkeligt at
apple ikke informerer om den slags i specsne, men s�dan er der jo s�
meget.

Sweet!
