You know I always got the impression that Intel chips ran much cooler than AMD chips- yet I look on the spec for my 2600+ and it has x amount of transistors (from my understand what causes the heat) yet I look at a 2.6 ghz p4 and I see that it has 1.5x the number of transistors... which really got me thinking.

When I looked into the specs further I saw that the P4 puts out about 14 Watts of heat more than the 2600+... which was very suprising.

It's not an across-the-board kind of thing. GENERALLY, very generally, the Athlon 64 processors run cooler than the Pentium 4 processors. Similarly, the Opterons run cooler than the Xeons. I would say that the Pentium M runs cooler than the Athlon 64-M or XP-M. I define cooler in terms of power dissipation--with the right heatsink/fan unit, one could make just about any processor "cooler" than another processor.
 
large heat spreader on P IVs and A64s should make them run cooler but I can't really complain about my TBred which runs at 41C max (1700+ @ 2200+ with lapped stock HSF)
 
Technically, a P4 runs hotter (per unit area) than a nuclear reactor. :p
 
ya, but danm those new prescots run hot... if i got one id get the $$ by selling my microwave on ebay, b/c i could just use my comp case :p
 
p4's run much cooler and can withstand much less heat than AMDs.


there I said it.

Game over.
 
I was told time and time again and flammed that intel uses less power and generates less heat..........who knows if this is true.
 
But the 2.6 ghz p4 puts out more wattage of heat than the AMD 2600+... wouldn't that qualify that Intel is hotter?

Looking At your sig: How the heck can you overclock a monitor?!
 
Prescotts run the hottest, period. Some Northwoods run hotter than some Thoroughbreds/Bartons. It is a stupid question, IMO, because the answers can be found at Intel and AMD's respective websites.
 
Lol, it's halfway a joke: here's the way you can OC your monitor.

In some resolutions my monitor is spec'ed to do 75 hz(fps). Now when You get a monitor over rider you can change all default settings for a monitor and in the resolutions I use I changed all of them to 85 hz.

Thus, when I went form 75 hz to 85 hz I effectively OCed my monitor :D.

~Adam

PS: lol that joke thing was rather funny *wipes egg on his face* :D :eek: ;)
 
Would going from 75 Hz to 85 Hz really make a difference anyway? lol. Sorry, first time on these forums, I see people still have good senses of humour even on computer forums! :cool:
 
INTEL BY FAR runs cooler (atleast the Pent. 4 series does as compared to the Athlon XP series). However, either way, they all can run at their stock speeds...and if your wondering which one runs cooler for OCing purposes...FYI...thats all about how much luck you have in getting a good OCable chip...
 
I have an old P4 @ 1.7GHz, you know, the old .18 process. I'm lucky if I can get that CPU under 55C idle! I have 10 total fans in that machine but I modded my CPU fan to run 1.4 times the RPMS that it normally would. I have another AMD 64 3400+ that runs about 38C idled and 45C full load. A LOT cooler than the P4. Also you have to remember, each CPU has its own voltage, which also affects temp. My old P4 ran 1.75V whilst my AMD runs at 1.5V.
 
Ok. I am expencting to get flamed after saying this, but where can I find out how hot my CPU runs? I only just started learning about this stuff, and just recently found out the difference between a Socket 370 and a Socket 478. lol!:rolleyes:
 
Can i just start by saying that through my experience, AMDs always seem to run hotter than Pentiums, although this may have changed recently (plz don't flame me).

Some mobos have a special attachment to connect a thermal sensor to to heatsink of the chip. But i did see a monitoring program pick temps up and we didn't install a thermal sensor, so i'm now not sure wether the chip picks up its own temps, or the mobo picks it up (i know ASUS mobos still have the sensor option). Dammit, i can't remember the name of the program either. Oh well, help is needed here too. :rolleyes:
 
Nobody noted the mobile XP's

Those would have to be the coolest, especially the new low power 2100+ I'd imagine.

Ummm...no. I work with nuclear reactors and this is the dumbest thing I have ever heard. This is simple untrue. I'm not going to give any numbers but lets just say that a nuclear reactor is MUCH hotter and also puts outs MUCH more heat even if you were able to get an equivalent area of P4 dies all together. Sheesh. Stop believing everything you hear....let alone spreading stupid rumors like this. :rolleyes:

Wow, I imagine the guy said it as a joke meaning that P4's run hot. wowzerz, way to take it seriously.
 
Who gives a shit??? Really? If you add a good quality HSF, into a case with a well thought out cooling setup, any processor will be fine. Prescotts are VERY hot, so maybe they are outside this comment, but in general, it doesn't matter which is cooler, AMD or Intel. It is MUCH more important to know if your system is cooled. A chilly system is a good home for either.
 
I personally though Intel ran cooler then i got my prescott. I have had many AMD and Intel Systems, and by and large i've never seen a AMD system go over 48 C at load, and this one that i have is loading about 54 C right now So in answer to your question. I guess it matters what version of the AMD and intel processor you are talking about.
 
not especially. they don't have much cache in them tho, so a high clock speed is needed to make it run as well as the standard p4.
 
I deal with thousands of cpu's weekly.

By far, Intel p4 cpus run at least 10c less in normal conditions with compareable heatsink / fan applications.

There are not many Athlon XP's that run SUB 30c with stock heatsick/fan.
 
my athlon XP palomine needed an active HSF to stay cool even in the bottom of my junk drawer...

up til the barton and athlon64, AMDs ran so goddamn hot. anyone with an old tbird or palomino will agree..

and i dont know if anyone said this, but more transistors usually means cooler temps, as the current has smaller paths to traverse...
 
Here is the order as I understand it, hottest to coolest

P4 Prescott
P4 regular
AMD Athlon (non-XP)
Athlon XP
Athlon XP Barton
P!!!
XP-M
Pentium M

For once I agree with djnes. Who gives a shit? Honestly...
 
Who gives a shit? Sorry but for those of us who sit in non-room temp controlled rooms this is a big issue.. who cares... please. Take that shit elsewhere.

Well I think that the p4 cpu hsf's have been better quality than the amd, they are much bigger and more surface area- which is probably why they can be overclocked well.

I want the biggest p4 hsf to stick on my xp and compare temps... now that would be an idea.

There's a great list of processor electrical specifications. Both AMDs and Intel's chips have a high heat output, with Intel's chips having a tendency to put out slightly more heat at comparable performance levels. However, the stock heatsinks that come with Intel's processors tend to be larger, and perform somewhat better (when referring to the xp series, I haven't had a good look at the 64-bit stock heatsinks).

Both companies offer viable low-temperature solutions. You simply need to decide how large your budget is, and what this computer needs to do.
