Next ATI chipset has four pipelines, X600 like graphics
 

WE HEARD that ATI is working hard on a new integrated graphic core. This time it aims to have four pixel pipelines inside its chipset. Both Nvidia and ATI have only two pixel pipelines.

C51 and Radeon Xpress 200 chipsets both have two pixel pipelines powered with Hypermemory or turbo cache marchitecture. They can run some games at 800x600 and they can let you see some of the games before you go out and buy a decent graphic card.
