In Dec 2007, NVIDIA quietly unveils GeForce 8400GS with a new core: G98. But this time NVIDIA keeps low, did not make any announcement. Even their official site did not have any information about it. What’s more, in the market we can hardly find a G98-8400GS
The new GeForce 8400GS(D8M)
As a new core in the market, G98 is for high definition segment. The biggest point of this new core is PureVideo HD gen 3, Supports VC-1 video 100% hardware decode. With 100% VC-1 and H.264 decoding, pureVideo HD gen 3 can finally fight against UVD.


Doesn't this still have exactly the same Purevideo HD features as the original 8400/8500/8600 etc, so it'll really be no different image wise.
