Cpu Round Up Sub 100 Intel And Amd Processors Tested Power Consumption

On average, the Athlon II X4 630 used 52% more power than the Pentium G6950. The Phenom II X2 555 used 39% more, making it far less efficient given the performance that we saw throughout the benchmarking phase. Even the single core Sempron 140 uses more power at idle than the Pentium G6950.
