Originally, ATI announced this feature would only be supported in Vista, but in August 2008 they included support in their Windows XP drivers as well. The architecture has been patented by ATI.

Hybrid CrossFire / Hybrid CrossFireX

The Hybrid CrossFireX is a technology allowing the IGP, or Integrated Graphics Processor, and the discrete GPU, or Graphics Processing Unit, to form a CrossFire setup to enhance the system capability to render 3D scenes, while the Hybrid CrossFire X technology is present on the 790GX and 890G chipsets, with two supplied physical PCI-E x16 slots at x8 bandwidth , can form a Hybrid CrossFire X setup with two video cards and the IGP, enhancing the 3D rendering capabilities.

Initial performance results paired with a Radeon HD 2400 video card leads to a 50% performance increase over standalone Radeon HD 2400 performance , notebook products will also be available. Three operation modes were spotted as follows:

Notes:
  • 1. Hybrid CrossFire X is only available on 790GX, 780G, 760G, 785G, and 880G and 890GX chipsets.



One notable issue is that when the IGP paired with a DirectX 10.1 video card, the whole hybrid CrossFire setup will support up to DirectX 10.0 only, and the UVD in IGP will be shut down. The new 785G chipset has solved this issue however and supports DirectX 10.1.

 port), in "extended desktop mode" or "duplicate mode", for better desktop utilization and to provide more flexibility. The integrated graphics processor and the discrete graphics processor work in parallel to drive multiple displays. Therefore it is different from Hybrid CrossFireX.

PowerXpress

Available on mainstream mobile IGP chipsets (AMD M780G and M690), the PowerXpress technology allows seamless switch from integrated graphics (IGP) to discrete graphics on notebooks when the notebook is connected to the AC power supply for better 3D rendering capabilities, and vice versa when disconnected from power supply to increase battery life. The process does not require a system reboot as in past and some current notebook implementations. Current Linux support of this feature is not complete but related information can be found in the Linux Hybrid Graphics page.
