GPU
Future CPUs will have C6 power saving mode that causes them to
have wide dynamic load range from their respective maximums to only
1W!
MAX 1WMAX 1W
Future GPUs will feature hybrid mode. When system is idle or in 2D
mode, the discrete GPU(s) will hibernate and shift all GPU processes
to CPU or chipset. This means they have such a wide dynamic load
range as well.
