Yes but my point is: if I download the AVX version instead of the SSE version of a package and that makes my 1000 servers 10% _quicker_ that is not the same as being 10% more _efficient_.
Because typically these modern things are a way of making the CPU do things faster by eating more power.
There may be savings from having fewer servers etc, but savings in _speed_ are not the same as savings in _power_ (and some times even work the opposite way)
