Which CPU runs hotter AMD or Intel?

My friend and I arguing weather AMD or Intel CPU run the hottest assuming both are running at the same speed.
 
Current generation: Intel

But this also depends on what you mean by "speed". Are you talking an A64 3500+ against a P4 3.5. Or, are you talking actual mhz to mhz.
 
Older AthlonXP vs northwood the AMD is much hotter

Prescott vs AMD64 = Intel is hotter

AMD64 vs williamette = close tie
 
Well, we were discussing those currently on the market at the moment.

P4 or P-M, desktop A64 or Turion?


By speed I ment Mhz to Mhz

MHz to MHz is largely irrelevant from a consumer standpoint, and difficult to say at that given that Intel's action is all at or above 2.8GHz and AMD's is pretty much all below. Are you sure you don't mean PR rating to MHz (i.e. 3800+ to 3.8GHz)?

This is the answer to your question. Even at Mhz - Mhz comparison. Usually it boils down to the die size used by the CPU. The lower the cooler.
 
In order to get a AMD to run at the same Mhz of an intel you'd have to do a major overclock thus making it hotter, but then the AMD would have far better performance. I don't know why you would do a Mhz-Mhz comparison since performance is what matters, not Mhz.

MHz vs MHz would not be the same speed...

AMD FX-57 - 2.8GHz @ 104W
Intel 2.8E - 2.8GHz @ 89W

At the same speed, AMD runs hotter. 😀

Thats if they were the same Ghz.

And wouldnt that FX-57 be overclocked? *tut* *tut* 🙂
 
LOL...Ok Blain show some benches between the 2 and lets see if they act like they are the same speed 😉
 
for similar price points, anything prescott runs the hottest... sure the FX-57 is one of the hottest, but that's just.. not fair. 😉

overall the A64's are a nice fairly cool running CPU.

Who runs a 2.8? both my Prescots 3.2 478 and 3.4 775 run hot. my 3.4 idl @ 46C with the present setup my 3.2 idl @55C with the present cooler with the stock it was ild @ 48C (broke the stock one)🙁 The reason the 3.6 478 was pulled after production was a heat issue.

 
This poll is like asking
Which Which Car has a bigger engine "Chevy or Ford"
Assuming that both are driven at the same speed.

We need exactingly specific models to compare 1 to 1. Otherwise it's just a generalization that doesn't mean squat.

Not a fair comparison with those wattage numbers.

AMD's max wattage ratings are theoretical but Intel max wattage ratings are in fact, slightly lower than the actual max. Pit a FX-57 vs a P4 2.8E in a full load power consumption test and the FX-57 should consume much less power than the 2.8E.

Like cars I think it has somthing to do with Performance the Hotter your engine, the better your performance = more heat so you need better cooling. :laugh: :laugh: :laugh: :laugh: :laugh:

really? link?
 
I went from a p4 3.0ghz processor to a amd64 3500. My 3500 is noticably faster then my 3ghz p4, yet it runs much much cooler. Especially because I have cool n quiet enabled. So it scales itself down nicley. But even under full load, the amd64 is much cooler.
 
The 64 3500 doesn't qualify as "same speed" of the P4 3GHz, since the 3500 is a 2.2GHz CPU.


BTW, In reference to my FX-57 / 2.8E comparison...
I have no doubt that an FX-57 would blow the doors off a P4 2.8E. 😛
 
Its insane to compare heat at the same mhz. At the same performance level, thats fair.

Intel runs hotter in that case for the current line of CPU's.

The FX-57 is a 2.8GHz 104W CPU, while the 2.8E is a 2.8GHz 89W CPU

1. Both are the "same speed".
2. The AMD runs hotter than the Prescott.
Does anyone dispute those facts? :laugh:

Whats "same speed" I am pretty sure that 2.8 FX57 is ah hell of alot faster then the P4. What people should be lookingat is more along the lines of price point. It doesn't make sense to compare hundred dollar P4 to a $1000 Athlon64. Also AMD unlike intel as stated above doesn't rate their CPUs the same way If you compair a 3000+ a 3200+ and a 3500+ The have the same TDP for all 4 when you know a 3500+ puts out more heat then the 3000+. AMD lists a gneral Max under the worst conditions, at the highest speed and voltage it could run at TDP for a process and not a certain CPU. For example the San Diego TDP could have been taken at 3.2 with some extreme voltage. Intel comes up with there numbers by what is stock speeds and voltages for each CPU and comes up with their number based on an in actuall use max.

"Same Speed" is as it sounds... Same MHz. 😛

He should really change his question to "same performance level". :laugh:
Until then, I will continue to pound the desk with AMD & Intel specs showing that the AMD runs hotter. 104W is hotter than 89W isn't it?
