With the development of the Atom processor, Intel introduced a totally new chip design that consumes very little energy. AMD had to strike back, and did so by clocking down its Athlon 64, employing the K8 micro architecture, down to the lowest possible frequency of 1 GHz. The Athlon 64 2000+ runs with a core voltage of 0.90 volts and uses just 8 watts. As a result, the CPU easily operates without a fan. If you drop the 8 W Athlon 64 into a motherboard based on the 780G chipset, then the system hits power consumption numbers that, in our measurements, are below Intel’s Atom desktop solution. We were even able to lower the core voltage by 11%, without stability problems, and the power analyzer read lower numbers. Interestingly, AMD’s Athlon 64 2000+ processor, unlike Intel‘s Atom CPU, is not embedded in the motherboard. It can be run on any board with an AM2 or AM2+ socket.
