1.3.1.6 Multiple Display Configurations
The following multiple display configuration modes are supported (with appropriate
driver software):
• Single Display is a mode with one display port activated to display the output to
one display device.
• Intel
®
Display Clone is a mode with up to three display ports activated to drive the
display content of same color depth setting but potentially different refresh rate
and resolution settings to all the active display devices connected.
• Extended Desktop is a mode with up to three display ports activated to drive the
content with potentially different color depth, refresh rate, and resolution settings
on each of the active display devices connected.
1.3.1.7 PCI Express Graphics
4
th
generation Intel Core processors support PCI Express 3.0, 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.
