Well, the benefit here would be battery life considering the chipset uses less power. Not too long about we were buying ~5-6lbs Dells and HPs that maybe got 90 minutes of heavy use or 120 minutes of light use. Now multi-hour life is the norm on a form factor that weighs almost half that. Performance, depending on your needs, is probably not CPU bound. My biggest performance upgrade was installing SSDs into all my equipment. Turns out I've been disk-bound this entire time. The CPU just sits there waiting for disk data. Even with super-fast SSDs most people aren't CPU bound. Now they're network bound (why isn't this webpage loading fast enough?).
