With a 20" LCD monitor the estimated load the dual 2.0 G5 draws through the built-in supply at around 235W at idle and 370-400W running full blast.gskiser said:I know it's not as easy to put it into a laptop. However, your 600 Watt comparison of the G5 tower is not completley fair. We're talking about the 970fx, which is different than what's currently in the tower. From what I've read, the 970fx, when clocked down to 1.6-1.8 actually uses less power than than the 1.5 G4 currently utilized in the PB's.
Makosuke tested his out as: "just idling quietly, it draws 170W and running all-out it's up around 325W."
The 970FX probably wouldn't be much different at the top end, since Apple is going to probably be pushing the new chips to between 2.5GHz - 3.0GHz.
But at the same speed, they are down quite a bit. But there is also the System Controller sucking down some Watts and creating heat.
A big way around this for the Portables would be to get rid of the 2nd processor port, a channel of DDR memory, and run the darn thing at 1/4 to 1/3 the CPU speed.
Basically the portable won't get the G5 until Apple makes a chipset that runs cooler than the one in the PowerMac.
