Core i7-2600K Overclocked: Speed Meets Efficiency

Features

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 One Core

The total power used to complete all single-threaded workloads depends on power consumption and the benchmark runtime. The differences are not significant, but we find that the higher overclocks actually do better than slight overclocks. It seems that the performance gain is more significant than the added power requirement.
