Faster memory and faster CPU.

I was talking theoretically.

As far as I know there are none.
AMD have had enough issues with Global Foundries' 32nm SOI process without trying to make specialty ultra-low-voltage chips on it.
Hopefully the process has settled down now and AMD's and GF's engineers have the hang of it.
