Icon"Looking over our EIST results today using a Pentium M 750, Intel's technology certainly has its advantages. Switching between the five power-modes, there was evident change in the CPU temperature as well as the power consumption. In addition, the frequency/voltages immediately scaled appropriately when switching between demanding and non-demanding environments. For those, however, seeking to over-ride the switching process at a low frequency/voltage, in order to conserve the battery life, heat output, and noise will find the performance to be severely hampered. As the last portion of our tests had shown, the compilation time had increased 212%, encoding time 218%, frame-rate had decreased 5FPS, and the Mflops had dropped over 233%."
