The process does not require a system reboot as in the past and some current notebook implementations, and it features a UI within the driver which can profile applications to run on specified GPUs. The successor of SurroundView is AMD Eyefinity.Īvailable on mainstream mobile IGP chipsets (AMD M780G and M690), the PowerXpress technology allows seamless switching 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 the power supply to increase battery life. Therefore, SurroundView is different from Hybrid CrossFireX. The integrated graphics processor and the discrete graphics processor work in parallel to drive multiple displays. At most four monitors with a discrete graphics card can be connected onto the supported video output ports (one through LVDS, that is either HDMI or DVI-D port and one D-Sub port), in "extended desktop mode" or "clone/mirror/duplicate mode". SurroundView is a brand/marketing term for the capability to drive multiple monitors as available in the ATI RS480 chipset. Furthermore, on this issue, there are certain APU+GPU combinations that only work in Directx 10 or above with the APU graphics being the default rendering GPU, notably A6/A8-3000 series and HD 6490/7400. However, the Japanese computer magazine ASCII has published charts showing worthwhile improvements for the combination of A8-3850 with HD 6450, HD 6570 and HD 6670, as have Tom's Hardware and Hardware Canucks. But the performance of a standalone HD 6670 video card does not appear to be stated or compared. AMD claims that – for an A8-3850 APU paired with an HD 6670 video card – dual graphics more than doubles performance (the benchmark increased by 123%) compared with the APU alone. The new 785G chipset has solved this issue however and supports DirectX 10.1.Īs of 2012, it seems that this "Hybrid CrossFireX" is called "Dual Graphics". 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. Hybrid CrossFire X was formerly only available on 790GX, 780G, 760G, 785G, and 880G and 890GX chipsets, but now A6-series and A8-series AMD Fusion APUs can be used in "Dual Graphics" configurations with HD 6570 & HD 6670 video cards. Three operation modes were spotted as follows: ATI Hybrid Graphics 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. 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.
