Which CPU is faster?

[MikeS]

I have a Dell Inspiron 1100 laptop and my neighbor just gave me his old motherboard and cpu from his desktop. It's a P4, would it be faster than the Celeron that came with the laptop?

P4
2.2 Ghz/512/400/1.5v
SL5ZU MALAY
L1520034-0518
INTEL 01

INTEL 02
CELERON
2.40GHZ/128/400
SL6VU CHINA
5402B155

Without saying anything about compatibility (someone else will fill in that particular gap), the P4 should basically trounce the Celeron, in speed, heat-output, and power-savings.

I agree on the speed(cache) , but wont the P4 use more power and generate more heat?
