1.4.1

PCI Express x16 Graphics

The Intel Core i7, Intel Core i5, and Intel Core i3 processors in an LGA1155 socket
support discrete add in graphics cards via the PCI Express 2.0 x16 graphics connector:
• Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (500 MB/s) per lane. 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 GEN2 mode.
• Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (250 MB/s) per lane. 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 GEN1 mode.
