Pentium M and Pentium 4 HT?

Question

hello.

Sorry if this is a dumb question.
I'm confused about the pentium M and the Pentium 4 with HT technology.
So my question is which is more faster or more powerful?
a Pentium M 2.0 Ghz or a Pentium 4 3.0 with HT technology?

thanks

from what ive read in reviews... p4m 2.0 for instance has measured up to some p4 HT processors like 2.4 and 2.6.

i dont know for sure but i had a P4 HT laptop (3.0) and i gave it back within a week... i do now in hindsite find it was infact SLOWER than my present 2.0 inspiron 9200.

Not only that but P4m will last a lot longer in battery life, and will not heat up as much. It will also (in theory) be lighter and slimmer.

The P4 HT machine had a battery life of around 50mins, stretched to an hour... it got too hot and uncomfortable for long periods of use. the fans were loud to keep the cpu at a useable heat level.

in my experience, if you want a laptop to carry around, forget desktop processors like the HT. If you dont want a desktop repalcement, then go for a centrino or a p4m.

Benefits will be lighter, slimmer (in theory), quieter, cooler (tempwise) and as much as tripple if not more the battery life compared to desktop CPUs

They're about equal.  The design of the Pentium M allows it to have the same performance as a Pentium 4 at lower clock speeds and with less power draw.  All things being equal I'd prefer a fast Pentium M over a fast Penium 4.  The only catch is that the Pentium M usually costs more.   (And by the way, there is no such thing as a 'Centrino' CPU, and the Pentium 4m is basically just a regular Pentium 4.)

i had no idea! well theres something i learnt today   i always thought p4m and pentium m were the same things!   so whats the difference between P4m and Pentium M ?   A

The P4m (called Mobile P4m) doesn't exist anymore. It used to be the mobile version of the Pentium 4 and existed in versions up to 2.6 Ghz. It has been replaced by the Mobile Pentium 4 (without lowercase "m") (for example Inspiron 5150).

Both mobile versions of the Pentium 4 are basically Pentium 4's with added SpeedStep capability (they can lower the clock and supply voltage when idle or only partially loaded). I also think that they can run even at full speed at a lower voltage than the regular P4's (I'm sure about the Mobile P4m, but not about the Mobile P4).

The Pentium M (for example in the 8600, 510m, 600m, 700m, 9200 Inspirons) has been completely redesigned to have great performance at very moderate power consumption (compared to the P4's). As I posted before, a notebook that has the Centrino logo has the Pentium M, the i855 chipset and an intel Wireless card (2100 or 2200).

@Akash84: Do you call the CPU in your 9200 a P4m*? In fact, it is calles "Pentium M" (with no 4), also sometimes (wrongly) called the Centrino. Centrino is a package of the i855 chipset, a Intel Wireless Mini-PCI card and the Pentium-M CPU.
(*The P4m was used for example in the i8500, with clock frequencies up to 2.6Ghz, FSB400)

Otherwise, I agree that the Pentium-M 2.0 should be as fast as a Pentium 4 3.0, HT can add some extra speed depending on the application.

The fun thing is the Penium M is really a continuation of Intel's 686 processor (ie Pentium Pro, 2 and 3). It's apperently going to replace the Pentium 4 archetecture in desktop systems too, as the P4 archetecture is kind of at a dead end. Message Edited by tigerwolf7 on 12-17-2004 08:04 PM
