AMD's HD 2400 Pro is always the first choice of those digital home FullHD playback users.(of course the driver have been a problem for some time) . NV fears and now pushing the new 65nm 8400GS.

G86 (8400GS) ——> D8M (8400GS)

As we said before, the new 8400GS(codename D8M and G98) is 65nm，and supporting PICe gen2. NV said that it supports HDMI and Dual Link HDCP. 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 appearence will not have any difference with the old 8400GS, and NV said the proformance 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 ful 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.

according to the NV's plan, the sample of the new 8400GS will ready in 17th Oct, the WQHL driver will finish in 7th Nov.By the way, the WHQL driver supporting 8800GT will out soon.

　　当AMD-ATi将拥有完整VC1及H.264硬件加速的Radeon2400Pro降价至399元之后，它成为了数字家庭用户最廉价有效的首要选择(这主要是硬件层面上的，软件上的配合一直问题不断)，这并不是NVIDIA愿意看到的，因此新版8400GS就要出现了。

G86 (8400GS) ——> D8M (8400GS)

　　和我们之前报道的8800GT一样，新版的8400GS(核心代号D8M，也就是G98)也将采用65纳米制程，支持PCI-E 2.0。官方宣称它支持HDMI和Dual Link HDCP输出，这点我们相信还是需要外置的解码芯片和SPDIF连接来配合，初步计划是采用256MB DDR2内存，显卡功耗将不超过30W。

　　在外观上你不会看到到新版的8400GS和旧的有什么区别，NVIDIA也表示新旧两个版本8400GS在效能上是没有区别的，由此可以判断频率应该是相同的459MHz/800MHz(核心/显存)。新版本8400GS除了刚才已经提过的PCI-E 2.0支持之外，最大的改变就是完整的VC-1解码加速功能(Full VC1 Decode)，这点已知的所有NV显卡都没有做到，我相信传闻的"PureVideo3"logo会很快出现。

　　在价格方面，新版的8400GS价格将不会做任何调整，维持在之前8400GS的水平。

　　按照NV内部的计划，新版8400GS的样品将在10/17准备好，WQHL驱动11/07完成，上市时间暂未确定。顺带一提的是，8800GT的WQHL驱动完成到上市也只是相隔半个月的时间。
