Nvidia reportedly selling 128-bit version GeForce 8400GS chips in China

A 128-bit version of Nvidia's GeForce 8400GS chip which was not in Nvidia's original roadmaps has recently been reported to have surfaced in the China market, according to sources at graphics card makers.

The 128-bit version GeForce 8400GS chip is very similar to Nvidia's GeForce 8500GT due to both graphics cores adopting the same G3-128 package, but the 8400GS's core frequency is lower, noted the sources. The original GeForce 8400GS adopts a G3-64 package, explained the sources.
