Overview
Introducing ATI Hybrid Graphics Technology
ATI Hybrid Graphics is a ground-breaking technology featuring multi-GPU
performance capabilities, automatic power state adjustment for
power-savings, and multi-display functionality. This AMD platform
technology enhances the user experience by combining an AMD 780
Chipset with integrated graphics and a discrete ATI Radeon™ HD
3000 Series or ATI Mobility Radeon™ HD 3000 Series GPU
so they work co-operatively yet independently of each other to
bring enhanced gaming performance, productivity and platform
power efficiency to the mainstream PC. ATI Hybrid Graphics includes
the following technologies: 
ATI Hybrid CrossFireX™ Technology
Based on ATI CrossFireX™ multi-GPU technology, ATI Hybrid
CrossFireX™ takes the gaming experience on a mainstream Windows
Vista® PC1 to the next level. When combining an AMD 780 Chipset
with an integrated GPU and a discrete ATI Radeon™ HD 3400
Series2 or ATI Mobility Radeon™ HD 3400 Series GPU, ATI Hybrid
CrossFireX™ combines the GPU performance and delivers high-quality
gaming images onto a single display.
ATI SurroundView™ Technology
ATI Hybrid Graphics technology enables ATI SurroundView™ which
provides support for 4 independent monitors when an applicable
integrated GPU is combined with a discrete GPU. Each additional
discrete GPU supports 2 or more independent monitors. The integrated
graphics processor and the discrete graphics processor work in
parallel to drive multiple displays for superior productivity.
ATI PowerPlay™ Technology
ATI PowerPlay™ power management technology enables the GPU
to automatically adjust between low, medium and high states for
efficiency and performance-on-demand. For example, when emailing
there is less demand on the GPU and it runs in a low state and
when gaming it runs in high state to provide the additional power
needed to play demanding titles. ATI PowerPlay does not require
both an integrated graphics processor and a discrete graphics processor
in order to operate.
ATI PowerXpress™ Technology (Available on notebook PCs using
Windows Vista® OS)
ATI PowerXpress™ dynamically switches (no reboot required)
in real time between an ATI Mobility Radeon™ HD 3400 series
graphics processor and an integrated graphics processor. Experience
superior discrete graphics performance while plugged in, or switch
to energy efficient integrated graphics when on-the-go to help
extend battery life.
Note: Performance, technologies and features can vary with
specific notebook implementations. Please consult with Notebook
vendor
for a complete list of supported features.
1 ATI Hybrid CrossFireX™ Technology is only supported with
Windows Vista® operating system, and is not available with
Windows® XP operating system.
2 ATI Radeon™ HD 2400 supports only ATI Hybrid CrossFireX™ technology
and ATI SurroundView™ technology.
