What is the difference between the Q6600 and the Q6600 Energy Efficient Edition?

Question

I looking to buy a Q6600, buy to my surprise i saw two versions. The normal Q6600 at £127 and the energy efficient at £119. Both have identical specs and both comes with go stepping, i'm just curious whether the energy efficient one clocks better or gets as hot less easily then the normal one. Thanks for your help
