Intel Vs AMD CPU's

What's obvious is instead of a microprocessor, you apparently bought the world's first socket 939 space heater, for your contention is that heat is the only output of your chip!

(this should be interesting) ...whereas you contend that part of those Watts end up,... - exactly where?

i am not an intel zealot, but saying they suck is just stupid and wrong.

That whooshing sound was a mild joke whizzing over your left shoulder.

i'm not qualifying my statement by saying i'm a physics major

it had more to do with the comment directly above mine

1. So as a physics major, you are stating that with equivalent HSFs on both CPUs, they are near the same temp...even though one uses twice the power. You need to get your money back...

1. With equivalent HSF's they still wouldn't be hugely different. The rate of heat transfer is determined by the difference in temperatures between the HSF and the Air. So if the Intel CPU is twice as hot, it will be dissipating more heat faster than the same HSF on an AMD chip.
2. Heat is not the only output from the chip. The main output from the chip is actually the signals it sends to the other components of the computer (Northbridge/memory etc...).

1. The rate of transfer is also determined by the efficiency of the thermal conductor, so yes they are indeed hugely different (unless you're using something like water or a peltier cooler).
2. There is no way that even 10% of the wattage is transferred away through signalling (or you would have a VERY hot FSB!), especially under load.

AHHHHHHHHHHHHH Attack of the physics majors!!!!! Physics Majors just hijacked the thread!!! OMG!!!!!!

Can't wait to take physics next year 😉

LOL...I'm not a Physics major though. I work in television (which means that I can learn anything except Brain Surgery...).

AMD64, AMD64 X2, AMD Opteron all run cooler than Intel.

First of all, how about some real data?

As you can see, AMD's CPUs consume roughly 65-75% the power of Intel's.

Its pathetic whe the biggest power hog AMD has uses less than Intels lowest power hog (in that sample)
