They both have same power consumption that is 45W but only in the case of dell inspiron SE they are providing a new model core-i7 model 3612QM that is lower clocked 35W model.
Well , Ivy bridge uses less power than sandy bridge processors. They have reduced the size of die , this has lead to reduction in power consumption when maxing out all the cores.
I have read this on PCMAG and couple of other websites too.
Here is the original text :
As long as we were testing the Core i7-2700K and the Core i7-3770K with otherwise exactly the same hardware setup, we decided to take some power readings using an Extech Datalogger. Though the full systems idled at almost the same electricity draw (about 71 watts), there was a stark difference when we maxed out all four of the processors' cores: The Core i7-2700K system needed 166.5 watts, but the Core i7-3700K drew only 136.3—a remarkable change.
Ivy Bridge processors introduce Intel's new Tri-Gate transistor technology, which replaces the traditional two-dimensional "planar" design with one that uses conducting channels on three sides of a vertical "fin" structure. This reduces current leakage, which in turn lets the chips use less power and better maintain performance.
It leads to around 50% less power consumption. ALso , it supports DDR3L low voltage memory.
On what basis are you saying that they both consume same amount of power practically. ?
