Less heat with the smaller nm, but only if all other things remain equal!

In reality, manufacturers use additional margin within their TDP to
improve the product otherwise. Perhaps they increase the clock speed
somewhat. Perhaps they increase the amount of on-die cache. Perhaps
they reduce the instruction pipeline.

AMD, for example, has tended to maintain keep something in the market
for a 125W, 95W and 65W TDPs for several years. Each year, the
functionality that used to be in a 125W TDP processor shows up in a
95W TDP processor, and the latest 125W TDP processor beats the pants
off of last years'.
