for A6 vs i3 your still limited by tdp when it comes to such things. a full 4000 could be running at lower clocks to maintain 25w or less tdp
in anands test the battery life of trinity vs hd4000 was about equal for their gaming (it was only mentioned in the text briefly, but it would be good to see how it really performs per watt in gaming)
Dual core IB run full speed HD4000, only the U (17W) models run at 350mhz, but still 1050/1150mhz turbo. the Dualcore IBs are the real contender for trinity. I doubt someone who really considers buying a quadcore for a a leptop wants to be ultra mobile with it and also only pairs it with only a HD4000...
