HotHardware.Com takes a look at a pair of energy efficient Athlon 64 X2 processors, more specifically the A64 X2 4600+ and the X2 3800+

Both AMD and Intel have made great technological strides when it comes to power consumption in their current CPU architectures. Both the Athlon 64 X2 and Core 2 Duo processor cores have elaborate clock gating schemes to allow their cores to ramp down during periods of inactivity or light workloads. AMD's line of "Energy Efficient Processors" takes this approach one step further by allowing operating input voltages to dip even further down, well below the standard operating range of the first Athlon 64 X2 and FX dual core chips that hit the market.
