VR Zone received information about three additional Intel Ivy Bridge ultra-low voltage (ULV) processors, you can learn about these models over here.
Let's start with the programmable TDP of the two models we already know about. The Core i5-3427U at stock 17W TDP will operate at 1.8GHz, but it can go down to 14W and all the way up to 25W. All models can go down in terms of TDP, but not all can go up. Its lowest speed is 800MHz, again something that is a common feature across the entire range, although at 25W TDP it can operate as high as 2.3GHz without going into turbo mode. The Core i7-3667U will be able to operate at speeds of 2.5GHz at a 25W TDP, up from 2GHz at 17W TDP..
