Amd radeon hd 7500g or intel hd 4000??

Solution
You've mistaken the whole cpu vs just the igpu. It is not 17w vs 55w considering the lowest amd cpu with it is a total of 17w which includes the cpu+igpu tdp combined. Also intel has a 18w cpu with it so the combined tdp can't be lower than the igpu alone. The top tier hd 4000 is only 8w. The performance is so close you should make the choice from the other specs.
