Nvidia isn't saying much about its next Ion platform, but if recent rumors turn out to be true, the followup platform looks to be a doozie. According to news and rumor site Fudzilla, Nvidia will double up the number of shaders on the second generation of Ion.

That means Ion 2, as it will likely be called, would ship with at least 32 shaders, providing a big boost to gaming performance on netbooks and nettops built around the platform. And best of all, thermals aren't expected to rise very much, if at all, on the upcoming shrunken version of Ion.

Nvidia's first Ion has yet to really penetrate the market and cut into Intel's Atom platform marketshare, but that could change as more major manufacturers jump on board. Samsung recently announced plans to launch an Ion netbook this month, and Lenovo's Ion-based IdeaPad S12 is due out in August.

Nevertheless, Fudzilla says Ion 2 should launch by the end of this year.
