nd
generation Intel Core processor family processors support PCI
Express 2.x and 1.x:
• PCI Express 3.0 with a raw bit rate of 8.0 GT/s results in an effective bandwidth of
1 GB/s each direction per lane. The maximum theoretical bandwidth of the x16
interface is 16 GB/s in each direction, simultaneously, for a total bandwidth of
32 GB/s.
• PCI Express 2.x with a raw bit rate of 5.0 GT/s results in an effective bandwidth of
500 MB/s each direction per lane. The maximum theoretical bandwidth of the x16
interface is 8 GB/s in each direction, simultaneously, for a total bandwidth of
16 GB/s.
• PCI Express 1.x with a raw bit rate of 2.5 GT/s results in an effective bandwidth of
250 MB/s each direction per lane. The maximum theoretical bandwidth of the x16
interface is 4 GB/s in each direction, simultaneously, for a total bandwidth of
8 GB/s.
