The mobile P4 is AFAIK virtually the same as the P4 ,whilst the other 1,which I think you mean is a Pentium M (not 4) is a special hybrid cpu for Laptops(etc) onlys ,it is a combination of PIII & P4 technology & clock for clock it is MUCH faster than P4!.

Anandtech has an article about it somewhere ,you should read it its quite interesting
