https://en.wikipedia.org/wiki/Westmere_(microarchitecture)

• Nehalem (and Westmere) allow much lower TDP CPU's than Sandy Bridge and Ivy Bridge (40W vs 60W).
• Die shrink of Nehalem, which reintroduced hyperthreading.

I'm using only sub-60W CPU's in my own builds to drive down noise and power...
This is adequate (I hope) for controller nodes.
