Replace Celeron D 330 2.66Ghz with Pentium 4 2.66Ghz?

I have a Toshiba Satellite A60-S1591ST with an Intel Celeron D 330 2.66Ghz and
a broken Dell Inspiron with a probably still working Pentium 4 processor. Could I swap out the two processors? It seems from what I could find on the Internet, that both are socket 478 (correct me if I am wrong). Also, the A60 series was available with a Pentium 4 alternatively.
Any ideas? I am mainly looking to reduce power consumption than to improve performance. Would the P4 use significantly less power?

 

well they are pretty much identical processors.....but I would think you would get a better power performance out of the pentium D

plus you would have to go through the hastle of actually swapping them....hoping you dont shock anything in the process (doesnt occur often, but it does occur)

just upgrade your battery if you really are having issues with it drawing down your battery

 

I was talking about replacing the celeron with a pentium 4 not a pentium D. Aren't those two different processors? And the battery life even with a new high capacity battery is only about 1.5 hours!

 

Yes they are different processors; the Pentium D isn't even a mobile CPU. If the upgrade to the P4 (which I assume and hope is a Northwood core, not the significantly hotter and more power-hungry Prescott version) is cheap, then go for it. I think you'll get better power consumption with the P4 because it has Speedstep, which throttles the speed of the CPU according to the user's changing needs, but google around just to be sure.

 

The P4 is free for me, since I would be taking it from the broken dell I mentioned. And I am more or less sure that it is the northwood core. The only reason that makes me consider the matter is if it is worth the risk.

 

There is very little risk involved in such an upgrade as the two CPUs are fairly similar; if you have any problems, you can always switch them back. Good luck if you decide to make the switch.

 

It won't save you any power, that much is clear though. The celeron is basically a crippled Pentium 4. The Pentium 4 is a power hungry but slow CPU.

Which means that the Celeron *might* use slightly less power, and is slower. But a P4 at 2.6GHz is pretty damn slow as well.

 

Are you sure about that, Jalf, as the Celeron D has no speedstep abilities, and according to bc135 the pentium does.

 

I would agree with Jalf if the OP were using a Prescott core, but Northwoods are much better in terms of heat output. If anything the Prescott was a downgrade from its predecessor. The P4 should yield lower temperatures, how low I cannot say. On top of that the P4 will have more on-board cache than the Celeron, which should yield a small performance increase. Can Jalf offer an explanation as to why the P4 wouldn't yield visibly better results?

 

Thank you everybody, for your opinions, I will probably see how easily my satellite's cpu can be accessed and base my decision on that.

 

Well, I did decide to do it, and am glad I did! After putting my lappy back together, and trying to boot, Windows decided to do some bickering and kept crashing, often not booting and showing me the 'blue screen'. It seemed to get better with every try, and when I finally localized at least one problem to a347bus.sys, deleted the file, and reinstalled alcohol 120%, the problems disappeared and have (knock on wood) been gone since. Anyways the results are:
1. Noticeably better performance.
2. Overheating problems disappeared. (Well, since I had my notebook apart
anyway, I cleaned the cooling fins as well)
3. Roughly 50% longer battery life!
