enabled in every case, as it is a processor feature. We repeated the power saving feature test at peak processor load and were surprised: Gigabyte’s DES only introduces a 1.7% power savings when the processor runs at peak power. The Asus EPU6 even...

we still did this, for the following reasons: They have the same thermal design envelopesWe wanted to see how high-end power saving processors compare to low-end hardwareBoth Socket AM2 and Socket LGA775 have been around for a while, so drop-in upgrades are...

the AMD Athlon 64 CPUs have turned into real power saving processors. Their modest power intake also reduces the amount of cooling needed, which is a real benefit. But with the introduction of dual core Athlon 64 X2 processors, power intake has increased once...

core reduces its power consumption even further by entering the C1 state via a halt command. In this state, the chipset is disabled, but the core's own registers and caches remain active. Even more power can be saved if the processor enters the C2, C3, or C4...

into an idle state earlier. However, the difference in power requirement between a mainstream 7,200 RPM hard drive and a 10,000 WD Raptor drive is only a few Watts, which only becomes important if you already tackled potential power savings in the processor,...

power draw for typical components, as well as the potential energy savings from using efficient PC parts. You will notice that the savings can vary heavily; this is due to many product options for various components, and their power draw differences: Processor...

energy. However, all modern processors come with built-in power saving mechanisms. AMD calls its technology Cool and Quiet, while Intel offers SpeedStep in the desktop and mobile segment and DBS (Demand-Based Switching) for professional products. The power...
