I disagree.
While Intel chips might use less power they run hotter. Same for Nvidia GPU's.
The max temp tolerence for Intel chips are much higher so yes they are more efficient in that sense, but in the reality of it all, with an AMD CPU and an ATI (AMD) GPU my temps are lower on all rigs on full load. and in the summertime when I'm fullscreen gaming and my 7970 is pumping out at 80 F Nvidia cards are pumping out much more which requires more A/C
95w to 125w? Pfff
I'll buy AMD.
Just because the sensor reads a higher temperature doesn't necessarily mean that the chip is dissipating a greater amount of heat. The amount of heat produced by a semiconductor device is a function of the amount of electricity flowing through the device in the first place. I can put an AMD E-350 on a passive heatsink to make it run at 80c and it dissipates much less heat than an FX-8150 @ 55c. Yeah, increasing the temperature of an electrical device increases the resistance and energy converted to heat, but that is negligible compared to the actual power consumption of the device.
Tell you what, I'm going to use my new IR thermometer to measure the difference between my FX-8150 and i7-870, and compare the readings to those from HWMonitor. Both are using the same Cooler Master Hyper 212 EVO cooler at 100% fan speed. I'm pretty sure both CPUs should be close temperature wise, but the FX will likely read lower on the die sensors.
My 7950 is running at 70c/50% fan right now while folding at 950MHz. NVIDIA cards believe it or not are much more efficient for F@H, and a GTX 470 easily doubles the PPD of my 7950. Gaming is a much different ballpark however, but the GTX 6xx has radically different power characteristics compared to the previous Fermi GPUs.
With that said, my 45nm Intel i7-870 CPU at 400MHz slower core speed is still slapping my 32nm FX-8150. We shall find out soon which platform is victorious (as I might actually compare my systems with my Kill-A-Watt soon to see what the PPD to KWHR ratio is).
