If the mode were attainable in a realistic end-user scenario, there would be no point in detecting the benchmark tool in the first place. A high CPU load (like from a benchmark) would kick the CPU up into high performance mode and that would be that. I would guess that the high-performance mode drains the battery so quickly, or creates so much heat, that it's impractical for general use.
