Most of Intel's Core i5 and i7 CPUs lock out overclocking enthusiasts, which we hate. But the K-series chips win us back over with insane scalability. Would you believe that cranking the dial on performance doesn't necessarily tank overall efficiency?
Efficiency Using Multiple Threads
Runtime in threaded applications decreases nicely as clock rates increase.
At the same time, power consumption increases with the clock speed.
It’s not really possible to determine a clock speed level that would have an advantage in total power consumption while executing our threaded workload. The differences are too small here.
