AMD is apparently set to release their next gen IGP RS780 chipset next month which includes support for DirectX 10.
The report claims that the chipset will support AM2+ processors, HyperTransport 3.0 and PCI Express 2.0, while the IGP will support DirectX 10 and UVD (unified video decoder) 2.0 for H.264 and VC-1 decoding.
The IGP also supports DisplayPort, HDMI, DVI and HDCP. The chipset supports Hybrid CrossFireX technology, which is a similar to Nvidia's Hybrid SLI allowing the IGP to work together with discrete graphics cards for extra performance.
