Energy Consumption: Cool’n’Quiet and the Complete System
The percent differences of energy consumption of complete systems with CPUs in Cool’n’Quiet mode is not significant.
The difference between the best Athlon X2 4050e with 73.4 W and the worst Athlon 64 X2 4800+ processor with 79.9 W is just 8.8%. When the processors alone were measured, the performance difference was 58.8%.
AMD’s Phenom sticks out when measured in a complete system: at 95.7 watts, the Quad Core model uses 15.7 W more than a classic Athlon 64, which represents a 19.7% increase.
