AMD Phenom II X4 940 

Released January, 2009
  • 3 GHz
  • Quad core
  • Unlocked
4.9 Out of 10

As well as higher clocks, AMD reckons the new process enables a power efficiency improvement of around 35 per cent.

I figured 1.45vCPU was a nice maximum vCORE for 45nm but expect much better overclocks down the road.
