It will be interesting to know how fast those lenses react to sudden changes of light. For example when driving from a dark tunnel right into sunny open road conditions or vice-verse.

Let us consider 3rd and 4th gen Intel Mobile Processors with 4 physical cores. As you can infere, we are focusing on energy efficiency for high performance mobile processors.
The TDP (Thermal Design Power) for 3rd and 4th gen
3rd gen (Ivy Bridge)
http://en.wikipedia.org/wiki/Ivy_Bridge_(microarchitecture)#Mobile_processors
35 to 55 Watts

4th gen (Haswell)
http://en.wikipedia.org/wiki/Haswell_(microarchitecture)#Mobile_processors
47 to 57 Watts (probably 37 Watt versions will appear)

I cannot see the "huge energy efficiency improvement". Maybe Haswell changes from high power state to low power state faster than 3rd Gen (which is good indeed) but that does not matter to the eyes of my examination.
