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.
