I am aware of the situation..see my post above. That is a very long report..I briefly skimmed through it but could not located the relevant section you refer to. Could you point me to it?Haven't you got the multiple message yet that 20nm will be more expensive than 28nm per transistors?
Look here for example: www.bnppresearch.com/ResearchFiles/31175/Semiconductors-230414.pdf
And also the information from ARM that the A72 is less power hungry than the A57 at the same process node (and the A57 was already less power hungry than the A15 from what I remember). See: http://www.realworldtech.com/forum/?threadid=147766&curpostid=147801
Yes..I have seen that..agreed that it may be more power efficient but we do not know to what degree. Besides even if a chip is more efficient, it can consume more power under load and it is the absolute power which will matter at the 28nm node..which is why we haven't seen any A57 implementations on it. Either ways..I'm not ruling it out..it's just unlikely in my opinion (i.e. that they will use A72 on a mid-range part and that it will be on 28nm)
