kinda like the thing "when will she have the baby" where you put in $10 and the person closest to the date/time the baby is born, wins all the money. except there's no money.

I thought the heat dissipation at like 1.3GHz was tiny and on par with G4s at a comparable clock rate. Is it not feasible that they put in lower clocked G5's in the powerbook? Not to mention they have the ability to go back further a la speedstep, we know this from the way they get throttled back when the G5 side panel comes off.

Edit, found something:

                              Process    Die Size     Transistors     Core Voltage       Power Dissipation
PowerPC 970      1.8 GHz      0.13um     121 mm2      52 million      1.3v               42 Watts
Pentium 4        2.8 GHz      0.13um     131 mm2      55 million      1.525v             68.4 Watts
G4e              1 GHz        0.18um   	 106 mm2      33 million      1.6v               30 Watts

From Ars, so I'd imagine that at something between 1.3-1.5 it's pretty acceptable. Here's another quote:

As you can see from the table, the 970 at 1.8 GHz is much closer to the G4e than to the P4 2.8 GHz in terms of power dissipation. This means that Apple will be able to use this chip in the kinds of innovative enclosure designs that make their hardware continually appealing, regardless of how it performs. Furthermore, a 1U, 970-based version of the XServe is not out of the question. And if you consider the fact that the 970's power consumption at 1.2GHz is a mere 19W, it's almost certain that we'll see a future notebook from Apple based on the new chip.

I'd have to say early 2005 with 1.5 Gig Processor, maybe a new design too, especially for the cooling system.

Probably be next machine i buy tho, be a while before I can afford to get an upgrade :(

i wouldn't think it would be very good business practice to "upgrade" from 1.3 to 1.3 GHz.

for this reason i would assume apple plans to release something like 1.8 GHz at least. you have to realize by the time the g5 powerbooks will probably come out, the desktops should be 2.6ish and the g4 pbooks will possibly get another speed boost with the old processor.

I feel bad for the poor soul that gets a revision A g5 powerbook because I predict that those machines will have quite a few initial flaws. Whenever they do come out, I'd wait for revision b.

That's quoting it's minimum at the current 0.13nm process. Beginning of the year they'll be on 0.09 and ramping up to around 2.5-3ghz so something which dissipates the same amount of heat as the current chip at 1.3GHz should be available around the 1.5-1.9GHz range I reckon.

That 1.3GHz is what's feasible now and like you said, won't happen tomorrow because it doesn't make business sense. But come Q1/Q2 next year when they're on 0.09 and ramping up it's suddenly really attractive.
