We found that Turbo Boost can provide (on average) up to a 6% reduction in execution time but can result in an increase in energy consumption up to 16%.

Turbo Boost Technology opportunistically boosts the frequencies of the cores on the multi-core Core i7 processor. Our isolation, paired and saturation tests showed that Turbo Boost can provide on average up to a 6% reduction in execution time. Turbo Boost Technology had the most impact on performance when the scheduling was not optimal; however, in all cases, Turbo Boost enhanced performance.

Turbo Boost also resulted in a significant increase in energy consumption because the processor requires a higher voltage to operate at Turbo Boost frequencies. However, current processors also support low power sleep states where they consume very little power.
