you're comparing their performance based on the transfer speeds of the expansion slots they were made for, which just doesn't seem like an accurate way to compare them.
look at T-F's gpu list.
Graphics Performance List
the intel is ranked #196, the 7200 is ranked #176, that's probably as accurate of a comparison as you're going to find.
there you go, the 7200 wins, just like Hefe had already mentioned.
and even if you got them for free, both are fossils by even the standards of a few years ago, so even if one is "better" than the other, they're both crappy cards at the end of the day.
