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...
according to wiki for IB, the TDPs are 35w, 45w or 17w. we already saw what 45w can do, and 35w will have the same base clocks with slightly lower turbo clocks. the 17w get drastically reduced base gpu clocks for a reason. even if turbo can go up to 1100mhz, that does not mean it might even come close to that. if the 45w chip was able to get incredible battery life when it gamed, then that would be an indicator that it ran at max clocks and still came no where near its tdp. but since it didnt, its very safe to assume that a 17w chip will probably get 1/3 the gaming performance, give or take cpu dependent titles.

theres a reason i wanted to see performance per watt of gaming. just cause something says it can turbo to infinity, does not mean it actually ever does.
