The thing that impresses me here is how good the open-source Intel drivers are, in performance, at least.
The Llano part is stronger in terms of hardware, so you'd expect the proprietary AMD driver to be able to pull out wins, since presumably that driver is about as optimized as it can get. The HD4000 gives it a decent run however (by which I mean performs at least 50% as fast). In fact, looking at the hardware capabilities, Llano beats the HD4000 by about what you'd expect, given perfect drivers.
So with Intel we have company whose open graphics drivers are as good as those developed with a proprietary driver model, which is very nice to see.
(For those complaining that the linux version of Catalyst is crap, in performance terms it generally isn't. Stability is another issue. I'm basing my comments above of the performance of the HD4000 vs Catalyst under *both* linux and Windows.)
