i dont wanna detract away from the current discussion of intel p4 and amd64,
but the p-m is something new and faboulous for laptops that intel has to get some props for
The Pentium M processor is the most important of the three, and it has been much-anticipated by those who value battery life over raw performance. It uses 25 watts at full maximum, compared to the >100W a Pentium 4 3.4GHz Hyper-Threading processor uses. This allows laptops to be smaller and lighter because the cooling system requirements are much lower, and it dramatically improves battery life.
the amd dtrs run at 75-80w i think and the low powered mobile amd64 in the ferrari uses 35w...
Because increasing the processor GHz also increases the power used, Intel created a more efficient design with the Pentium M. The Pentium M is set to slow down to 600MHz when at idle (where it will consume only 6W), and then just like using a gas pedal it will accelerate to its rated speed when you ask it to do more than just simple typing. This also greatly improves battery life without losing any of its impressive speed.
clock for clock. the p-m is better than the p4. but amd64 is still the most efficient clock for clock.
Then, with the recent introduction of the new "Dothan" version of the Pentium M, the L2 On-die cache is now FOUR TIMES that of a Pentium 4 (2,048k as opposed to 512k used in the Pentium 4).
With its efficient architecture, and the extended L2 On-die cache, the performance of a Pentium M is roughly 1.7 to over 2 times that of a Pentium 4 processor. L2 On-die cache is where the processor stores the instruction sets that it uses most often.

the predecessor to the p4, will be dual cores based off the pentium-m. its a new and exciting thing from intel coz finally after so long of marketing "more mhz is better" with p4s, intel is scraping that idea (mainly coz they were hitting heat barriers in upping presscotts cpu speed) and going to a naming system where their cpus arent labeled after their MHZ... something amd started coz they were making faster and more efficient cpus than intel even tho they were lower clocked

, it was just what I assumed big business would do when this sort of thing comes out and I just spoke too late, lol.
