I'll try to find the source, but I'm pretty sure there are some issues with Chrome on OSX, and that these are thought to be the fault of Chrome. For example, testing has shown that Safari achieves significantly better battery life when running on the same set of pages.

Edit: Found it [1]. A couple of salient quotes:

"I ran the usual Verge battery test on Apple’s new machine. [...] Safari made the new Retina machine look good: 13 hours and 18 minutes. Google’s Chrome, on the other hand, forced the laptop to tap out at 9 hours and 45 minutes."

"The widely used SunSpider browser benchmark clocks the MacBook Pro in at 203ms when using Chrome. Safari scores 30 percent better with a time of 144ms."

There are definitely problems with Chrome on OS X, and it's not just performance. Lots of rendering problems when trying to set background-position: fixed; for large (i.e. "full screen") images where the background images either doesn't show up at all or hops all over the screen.
