Take the 4570S vs 4570 for example. Is the low power because of the lower clock speed, or is there more going on in the background in order for the processor to be low power? Also is the saving in power significant? The TDP of the 4570 is 84w yet the 4570s is 65w. Is this because of lower idle clock speeds?

At a guess I would say lower clock speed = lower voltage. My 4670K clocks down to 800mhz and 0.736v at idle so even the normal Haswells aren't exactly power hungry.
I believe the difference in TDP is due to limited a cap on the clock speed. (Both turbo to the same but their max base clock is different.)
When I was looking for a low power chip for my Media Server I was looking at the i3-2100T but all the information I found about it suggested that it was just an i3-2100 with limits imposed on it's maximum clock and that at idle they essentially have the same power consumption.
The moral being; it's probably worth getting the normal version and underclocking/undervolting it.
