Yes but those are duals, and running faster than 1GHz.
got yourself no powermac dual for $1499.00 it's a nice and clean 1Ghz machine running on a stinking slow 133mhz bus you can buy yourself for that price. it's called a low end and it replaced the 867MhzDP low end (slower?). (nobody was buying the 1GhzDP and 1.25GhzDP no more so apple killed the DP configuration in the low end)
no man, clive is right about the heat issues concerning DP G4's faster than 1Ghz in a 17"pb shell

Ok, I think we are confusing each other.
I am not talking about putting dual chips (970 or G4) into a powerbook. What I am asking, is if the desktop G4 chips (7455, right?) are the same as the latest laptop G4 chips. If they are not, what chips are in the laptops, and what wattage do they dissipate.
Clive claimed that they had to be differnt because the heat sink was so huge on the "WindTunnel". My argument was the heatsink was so huge because you have dual processor 1GHz+ chips. A single 867MHz or single 1GHZ woudln't need such a large heatsink.
But I have answered my own question (I think). I ran:
ioreg -l | grep cpu-version
on my 12" 867 and my desktop 867 and got back two differnt results.
desktop = 80000201
laptop = 80010303
So something is different about the chips. So if the ~15 W is correct for a G4 laptop at 1GHz, then 970 based laptops could be held off until the 90nm transition. Well, the 17" could maybe get a 1GHz and 1.2 GHz chip, but would they have a powerbook line that was split chip wise? I doubt it.
They already do, don't they? The 12" has different cache to the 15" and 17".
It's still called a G4, but it is different .
If you reread my post, I say chip wise. The G4 in the 12" and the G4 in the 17" are the same chip. The only difference is having or not having L3 cache, other than that the chips are the same. It would be totally different having some powerbooks with 970s and some with G4s.
I doubt they would have different chips in the same product line. Just like I doubt the Powermacs would be split G4 and 970, I don't really see Apple doing this with the laptops. But who knows...

Are they? I thought the 15" and 17" sported 7455s while the 12" had a 7445 (smaller, no pinouts for L3).
I've no idea what "chip wise" means, do you mean "same family" ie G4, same model, same part number? If you're going to assert that they are the same then I think you should post a reference that states this is so.
As far as the 970 goes I think it's fairly likely that Apple will have a two-tier desktop line-up upon its intro. My guess would be that they'll have "crippled" motherboards in the low end, with the high end getting bells and whistles. It could even happen that you get G4 for the lowest spec machine and a 970 in the upper end.
It would seem logical, that whatever architecture they adopt for the new machines, that it is compatible with both 970 and G4 - so that they can have a common architecture across ranges.
Yes, the 12" has the 7445 part (no L3 pin outs) on it. There's a pic of the mobo on the web where you can read the numbers. The 15 and 17 do have 7455's, BUT, as I recall, these are not the same 7455's in the PM because they run them at a lower core voltage and generate about a third less heat.
12" Superdrive now $3499 (forget what it was before)
15" Combo $3799
15" Superdrive $4899 (wtf?)
17" Superdrive $6999 > $6299
That's just a combination of the price cuts with an adjustment for the stronger A$ now that it looks stable above US$0.60. You'll see price reductions on more things as they are updated as well.
Edit: Ok next time I notice the 2nd page before I post

I'm pretty sure the heatsink is the same on the single processor model. And yes, of course the PowerBooks have a different chip to the desktops!

So if the 15" and 17" are 7455, isn't that what is in the desktops? Are are they different?

Aaahhh, 30% appreciation in the $Au over the last 6-8 weeks coming through. And just in time for some serious new high end hardware too!
