generation Intel Core processor family processors support PCI Express 3.0, 2.x,

and 1.x and 2

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.
