System Power Consumption

Athlon Vs. Atom: Duel Of The Energy Savers

Under idling conditions, the AMD system consumes 1.7 watts less than the Atom-embedded board from Intel. At only 38.8 watts, the Athlon 64 2000+ system breaks a new record for desktop systems in our lab.

Under full load conditions, the AMD processor remains a step ahead. With 2.3 watts less energy consumption, the Athlon 64 2000+ system beats Intel’s Atom-based board. At 41.9 watts under full load conditions, AMD also sets a new record in our lab.

When measuring the energy consumption of the entire system, AMD’s 8 watt processor performs better than Intel’s 4 watt processor, due to the lower power consumption of the chip set.
