Which dissipates more heat - Intel or AMD cpus?

[Eitce]

I've heard that Intel CPUs dissipate less heat than AMDs. Anyone have information about this? Note that running temperature is irrelevant ("my athlon runs at 30 celsius but jim's pentium runs at 40"), because heatsinking and fans just move dissipated heat to other places in your room. I want a computer that isn't so much of a furnace because it's hot as hell in here all the time. Thanks for any info.

dont cpu's produce heat instead of dissapating heat?

with that, i think i read that the p4 3.06ghz produces a record 85W of heat! i dont remember the exact number tho...

AFAIK 2Ghz P4 Willy was 107+ watts.

I believe Intel processor create more heat, but people are under the impression that AMD's do just because they run hotter. They only run hotter because the core is smaller, so there's less area to dissipate the heat through.

Go into an Anandtech CPU review on Thoroughbreds, Bartons, or P4's and he lists the thermal maximums.

Welcome to Anandtech!

There is no way to answer your question unless you provide specific information on the CPUs you wish to compare. Here's a chart that shows the power dissipation of virtually every AMD and Intel CPU ever made. You an use it to compare whichever AMD processor to whichever Intel CPU that you want. There is no hard and fast rule about AMD vs. Intel power dissipation. Look at the specs for the range of processor speed that you're interested in and then you can make a comparison.

THink of it this way,

AMD processors are like throaty V8's, more torque but less horsepower and dissapate more heat because of this.

Intel processors are like turbo-charged V6s, more horsepower but less torque and dissapate less heat.

I dont know if this makes sense but I had fun writing it.

i hope u had fun, cause i don't think that analogy was quite corrent

 

[Eitce]

Wow, thanks for the responses. Nice chart, Ralf. Also I know way more about processors and computers than I do about cars, so the V8 analogy was kind of lost on me.

Where have i heard that before hmmm............. I think p4's are better equipt to deal with heat.

The P4 2.8 GHz has a thermal spec of 68.4W, the 3.06 has a thermal spec of 81.8W, the 3.00's spec is 81.9W, while the AMD's 3000+ is listed as 74.3W. Hyperthreading had a big effect on the power dissipation of the P4's since it increased the amount of work the CPU can do. I'll welcome the .09u process because it will reduce these numbers.

As for temperature, I really couldn't say since since it's not really intuitive, but rather like an energy density quantity. You might want to consider undervolting/underclocking your CPU perhaps, or getting an LCD monitor. A CRT puts out more heat than most people would guess. Peace.
