Switchable graphics/dual graphics (select models only)
Select computers are equipped with either switchable graphics or dual graphics.
●
Switchable graphics—Supported by both AMD™ and Intel. If your computer has AMD dynamic
switchable graphics, it supports only switchable graphics.
●
Dual graphics—Supported only by AMD. If your computer has AMD Radeon dual graphics, it
supports only dual graphics.
NOTE: Dual graphics can be enabled only by full-screen applications that use DirectX version 10 or
11.
NOTE: To determine whether your computer supports switchable graphics or dual graphics, see
your notebook graphics processor configuration. Intel Central Processing Units (CPUs) and AMD
Accelerated Processing Units (APUs) support switchable graphics. AMD A8, A10, and FX APUs
support dual graphics. AMD A4 and A6 APUs do not support dual graphics.
Both switchable graphics and dual graphics offer two modes for processing graphics:
●
Performance mode—Runs application with optimal performance.
●
Power Saving mode—Conserves battery life.
Using switchable graphics (select models only)
Switchable graphics allow you to switch between Performance mode and Power Saving mode.
Switchable graphics assigns individual applications to either Performance mode or Power Saving
mode, based on power requirements. You can also manually modify the settings for an individual
application and switch between Performance mode and Power Saving mode.
NOTE: For more information, see the switchable graphics software Help.
Using dual graphics (select models only)
If your system is equipped with dual graphics (two or more added Graphics Processing Units
(GPUs)), you can enable AMD Radeon Dual Graphics to increase application power and performance
for full-screen applications that use DirectX version 10 or 11. For more information about DirectX, go
to
http://www.microsoft.com/directx.
NOTE: Dual graphics systems only support automatic selection based on power requirements
(Dynamic scheme), and automatically assign Performance mode or Power Saving mode for individual
applications. However, you can manually modify the settings for a particular application. To enable or
disable AMD Radeon Dual Graphics, select or deselect the check box in the AMD Radeon Dual
Graphics section, which is located in the Performance tab in the Catalyst Control Center.
NOTE: For more information, see the AMD software Help.
