Ars Technica on Nehalem
Integrated memory controller, and integrated graphics in some models! Nehalem represents Intel's biggest change in system architecture ever. The front side bus as we know it will be replaced by something called CS. Intel projects a release in the second half of 2008.
I'm pretty excited about these new products. We should see some spectacular stuff in notebooks in the next two years
