Did you try scrolling using Safari instead of Chrome/Firefox? With the Retina display, scrolling is significantly smoother on Safari (aka it's not smooth on a 15" Retina on Chrome either).

That is a good thing, because it means that Chrome should be able to fix this fairly easily.

This is especially apparent on pages with fixed background images. See https://code.google.com/p/chromium/issues/detail?id=155313
