A small message on Intel's PR blog reveals the company has introduced the Atom N470 processor:
Today Intel introduced the Intel® Atom™ processor N470. This new, faster Atom processor for netbooks has integrated graphics built directly into the CPU to help enable improved performance and smaller, more energy-efficient designs for the popular netbook category. The single core Atom processor runs at 1.83GHz, with 512k of L2 cache and DDR2-667 support. Major OEMs are expected to introduce systems based on this processor over the coming months to further differentiate their netbook offerings with a higher frequency to deliver additional responsiveness for online and basic computing tasks.
