A recent trend for cpufreq is to boost the CPU frequencies for iowaiters, in particularly to benefit high frequency I/O. We do the same and boost the GPU clocks to try and minimise time spent waiting for the GPU. However, as the igfx and CPU share the same TDP, boosting the CPU frequency will resul
