Final post on this subject
Unfortunately as i have stated earlier, Developer notes do not mean anything and if you look at developer's notes from all of Apple's computers offered now or earlier, they use the information from the highest end avaiable. if you go to look at the link for the Powermac g5 below, you will notice that it does not talk about individual models and just about the high end model, it distinctively leaves out the fact that the 1.6 ghz model can only take four gb of memory or has a slower bus speed. The same goes for the powerbook line of computers.
actually, i should put in quote that i am wrong about the 15 inch Powerbook, when looking through the developer's notes they directly link the processor to the New MPC7447a processor, now this is not saying that the base model is still not using the MPC7447, but i am because do not have endless time in the world to argue this fact, say that the 1.33ghz used in the 1.33 ghz powerbook has the possibility of being a 7447a, but i want to point out that i am correct and 100% correct since most people are citing developer's notes, that the 12 Inch Powerbook is Using the MPC7447 processor and not the MPC7447a processor like some people say, i will point out that because of this fact, which is supported by looking at the Developer's notes posted earlier for the 12 Inch powerbook from developer.apple.com that the 12 inch powerbook uses the MPC 7447 and not the MPC7447a processor.
I will state that because of this it is likely that the base model 15" powerbook uses the same 1.33 ghz processor used in the 12" powerbook but will not overlook the possibility that it may not and actually use the MPC7447a, then i would say why would apple not use the same processor in the 12" despite the fact that the MPC7447 is cheaper and that is one of the reason's it is used in the 12" Powerbook, That is why it would also be used in the base model of the 15" Powerbook.
To finish off with decisive evidence here is the schematic for the Powerpc g4 microprocessor used in the 15" Powerbook
As well as the Powerpc g4 Microprocessor used in the 12" Powerbook. If you look closer you will notice that 1) Apple does not send you off to Motorola's page on the MPC7447a when looking at the 12" pbook and does so on the 15" pb 2) That the 12" Pbook is missing fully symmetric multiprocessing capability and dual 32 KB instruction and data caches.
To answer an earlier question, is there a difference? no. I am revising my review of my 15" pb 1.5 ghz and stating that i have seen little heating improvements over my earlier 1.25ghz Pbook g4 15" and in terms of battery life, they are about the same.
I am not going to post again on this subject, i have rested my case and my opinion for that matter. Believe that your PB has the MPC7447a if you want or do not believe, that is up to you. To point out a reminder from data1ore, What you are typing with is what counts, if you have a MAC enjoy it because you are unique and able to stand there and watch your fellow computer(wintel users) machines crash and burn, while yours is still up and running, regardless of what you bought, you have the fastest powerbooks on the market and you should feel good about it

Yes, it seems you are right, all of them use the 7447A...
