ATi PCI Express IGP将内建9700 3D内核

ATi同时为AMD、Intel处理器推出PCI Express芯片组，ATi这些芯片组将采用DirectX 9图形内核，因此ATi下一代IGP芯片组将有很好的3D性能。不过，由于PCI Express 16x总线的功耗将是AGP8x总线的2倍，因此ATi移动PCI Express芯片组很可能采用PCI Express 2x作为图形接口。ATi下一代PCI Express芯片组在南北桥芯片之间，也将采用PCI Express2x或者PCI Express 4x总线连接，PCI Express2x总线带宽1GB/s，PCI Express4x总线带宽2GB/s。

为了支持到微软下一代Longhorn操作系统当中的Avalon 3D操作界面，ATi PCI Express芯片组内建的图形芯片，计划采用Radeon 9700架构，不过出于成本和未来处理器性能越来越强大的考虑，ATi PCI Express芯片组图形内核的顶点着色机能将交给CPU来完成。
