EXpreview reports NVIDIA is working on a new GeForce 8400 GS card to compete against the Radeon HD 2400 Pro. The new card will be made on a 65nm process, will support PCI Express 2.0, Full HD playback and HDMI and Dual Link HDCP support.
However we think it will use another decode chip to link up with the SPDIF. The card is using 256 DDR2 memory and the card TDP will not more than 30W.
The appearance will not have any difference with the old 8400GS, and NV said the performance are the same with old ones. So it is sure that the core/memory frequency is 459MHz/800MHz. with the PCIe Gen2. The new 8400GS will also provides full VC-1 decode, now all the cards NV have cant do this trick. So it's sure that the PureVideo 3 logo will appear in the new 8400GS card.
