centrino help

[dv13]

ok thanks...what I have learned between discussions here and other places, I THINK>.
The Centrino is more like a finesse processor, in that it does more in a cycle than the P4, which means that, now bear with me, what the P4 can do in a second, the Centrino can do in the same second at a slower ghz speed because the centrino is more robust and so on. another example, the P4 3.2 shoots straight through a process in a second, in a straight narrow lane. While the centrino 755 shoots throught the same process in a second also, but in a much broader lane at a lower ghz speed.
Which if I am correct then there is more to a 755 chip because it has to do a lot more in the same amount of time than the p4 in that time. Which to me logically would mean the 755 should run hotter..but it doesn't...as it seems to be doing more work in the same time as the p4...
If you understood anything of what i said above haha....am I getting the idea?

on the one post above, yes they have a P4m 3.2 ghz for a notebook, but it runs on 533mhz FSB, which means you lose the advantage of a 3.2ghz that you have with an 800FSB.

I had an Inspiron 8200 1.6ghz p4 and it really bogged down when using photoshop etc, and I just have to get awayfrom thinking that 2.0 ghz dothan is only 3.5ghz faster than the 8200...t

dv13, you got it except for the fact that centrino create less heat than a p4, and it sounds like you might want to know why...

Heat is created in a processor as it uses energy. A Centrino runs cooler than a P4 because it runs at a slower clock rate and on less voltage. The amount of work performed per cycle (IPC) has no direct relationship with heat. Here's one way to think about it. The electrical circuits in a processor change in "instant" bursts twice every clock cycle (once on the rising edge, once on the falling edge). In a nutshell, this "bursting" is creating the heat. The fact that the circuits are doing more work (are deeper, travel through more transistors) doesn't really matter because current flows "instantly". The fact that there are less bursts has everything to do with heat. Consider the voltage the "strength" of each "burst". It's kind of hard to explain via text but I hope you understand better.

"instantly" = the speed of electricity through silicon

Yes that helps a lot and thank you for the explanation. Makes more sense. I had 2 years of electronic engineering technology, but that was MANY years ago and I have not worked in the field much...so I have a good idea of what you are saying, even tho it is hard to describe in text...what you described brought back some of the college and I understand that more...thank you

Another question..Do you guys think Intel will come out with a faster Dothan in the near future? just wondering if maybe I should wait a short while on the laptop for that possibility...thanks..t

Please remember that "Centrino" is NOT the name of a processor. It's NOT something like Williamette or Northwood or Dothan.

Centrino is just a marketing term for a group of technologies. The CPU, motherboard, devices, etc. all fall under the Centrino name, and certain things must be present for it to be referred to as Centrino. A Pentium-M without wireless support on the motherboard isn't Centrino.

Poke around on the net and you'll find benchmarks. They usually show the P-M performing slower in CPU-intense things, and better in things that use all of the system resources. Games tend to fly on P-M's. Spreadsheet applications do not do as well.

ditto - and go 4 the new 7xx dothan/811G standard only

[dv13]

Hi and thanks..
Yes going with the 755 if I have to go the Dothan way.

Anyone know if there will be a Dothan faster than the 755 in the future, now that the sonoma's have been pushed back to Q1 2005?
