What's the difference between a Pentium 4 and a Pentium 4-M?
i think M is the mobile version for laptops
correct wookie.
Something like the Centrino?Quote:

so how about pentium 4 HT ? the problem is if i would like to upgrade from pentium 4 (normal - maybe the socket is A), so should be possible need to upgrade the motherboard too ?
HT stands for HyperThreaded. In some reports I've seen, hyper-threading causes some apps to run slower than on a normal processor, because they weren't designed for a HT processor.
how? do you remember where you read this? that doesnt sound right.Quote:

If I might suggest going to the INTEL website.
I had built a PC off of an ASUS mainboard
using P4 2.4 chip. I contacted INTEL
to speak about the HT (Hyper Threading)
the INTEL rep told me that there was no
chip that supported this feature.
Contact INTEL they will help you.
yes, apparently it will only use whatever power is required of it at any particular time. ie) if you are running an app that requires 50% cpu power, the M processor will only recieve enough power to run this 50% thus conserving battery life.Quote:

I thought the Centrino was just a chipset for laptops, not an actual processor. I saw one laptop that said it had centrino in it, and it said it also had a P4-M.Quote:

Then that laptop was either lying or trying to fool somebody :pQuote:

The Centrino is a more power-per-clock CPU than that P4 (kinda like AMD > Intel) so a lower MHz Centrino is more powerful than an equally clocked P4-M AND uses less power. You may see an extra 30 minutes of battery life from Centrino powered laptops. Pretty damn cool IMO :D
okay, thx. I wasn't sure about this.
Wow, I just found this link. I didn't know about what speed Centrino compared to a similar P4. I'm impressed! I figured a 1.7 GHz Centrino was similar to about a 2 GHz P4. Turns out it's far better, a 1.7 GHz Centrino is comparable to a 3.1 GHz P4!!!
http://voodoopc.com/systems/advanced.aspx?t=1&p=220 is just one link, though I've seen the numbers in other places as well. If you look at the first drop down menu (It's for CORE - CPU) you'll see the Centrino speed then it says right next to that the "performance rating" compared to a P4-M :)
I'm jealous now. My mom just got a new laptop from Dell with a 1.7 GHz Centrino. Wasn't too bad priced either, around $1500 if I remember right. With the exception of the junky Intel video card, I'd say her laptop would probably waste my nearly brand new home computer :(
> you'll see the Centrino speed then it says right next to that the "performance rating" compared to a P4-M
actually it says the M speed as compared to a pentium 4 speed. the centrino is a "wireless network solution"
Looks like I misread it :oQuote:
The new Intel Pentium M features an incredible amount of power with very little power consumption. Perfect for people on the go, this processor is more than capable of running todays most demanding applications. Don't let the speed fool you, this processor has 1 megabyte of cache and the performance beats all of the old Intel Pentium 4 Mobile Processors. *If you take the processor speed and multiply it by 1.9 you'll get a similar speed equivelant to the desktop Pentium 4 Processors in similar laptop configurations - according to our benchmark tests.
I'm confused myself then. I could have sworn the Centrino is a new processor based off of PIII technology with 1MB of cache. Is the centrino just a chipset combination thing (new chipset + new CPU) or is it a new CPU by itself? I know I'm not the only one that thinks is a just a new CPU, everything else I've read from other people has said the same :confused:
The Centrino is a combination of a CPU, chipset, and wireless hardware. The CPU is called the Pentium-M, which is not the same as the Pentium 4-M. Here, this link should clear up some details: http://www.pcworld.com/news/article/0,aid,109606,00.asp
What TravisS was saying is correct. From what I have read, the Pentium-M outperforms the Pentium 4-M. If you click the "I" next to that dropdown box he was talking about, it explains about the CPU.
doesnt centrino also have better built-in power management? i heard it uses alot less power than the p4-m
Yes, like I said earlier you can expect about 30 more minutes of battery life. Which of course on a laptop, is a lot :p
Does AMD have a specific processor for laptops, or do they just slightly modify their "regular" processors for use with laptops?
Some laptops can actually get ~6hrs of battery life from a centrino, comparing the avg. 2 - 3 hrs.Quote:

It's called the Athlon MP...but it's kind of unique, it's also used in dual proc mobo's in desktops.
That's kinda confusing. Just call it the AMD Mobile Athlon :)
The real athlon MP is used for multi-processor systems. I'm pretty sure there is a difference between the Athlon MP and the Mobile Athlon.
@Alpha:
I was just getting what I was saying from the Dell website. When we were looking at laptops the ones with Centrino had about 30 minutes more than the non Centrino ones ;)
