I did a little something different with this launch. Intel has used Turbo mode on their processors before but with limited overclocking. With the Lynnfield family I decided to run all tests with Turbo Boost mode enabled then run them with it disabled. Note that Turbo Boost frequency is dependent on the operating conditions of the CPU.
