External PCI Express x16 Graphics
The GMCH supports an add-in PCI Express discrete graphics card via the PCI
Express 2.0 x16 connector as follows:
• Supports the PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (500 MB/s total). The maximum theoretical bandwidth on the interface is
4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s when
operating in x16 mode.
• Supports the PCI Express 2.0 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (1000 MB/s total). The maximum theoretical bandwidth on the interface
is 8 GB/s in each direction simultaneously, for an aggregate of 16 GB/s when
operating in x16 mode.
