AMD PowerXpress5™ Technology
Most notebook computers come with either a discrete or integrated graphics solu-
tion.
Discrete ( High Performance ) graphics solutions feature a dedicated Graphics Pro-
cessing Unit (GPU) which are capable of playing games, watching HD video or run-
ning GPU-based applications. However computers with discrete graphics solutions
tend to be heavy in power consumption, and slightly larger in size in order to incor-
porate the dedicated discrete GPU.
Integrated ( Power Saving ) graphics solutions usually feature memory sharing
technology to help save power consumption and allow for longer battery life. How-
ever computers with integrated graphics solutions will not usually run games, HD
video or GPU-based applications without severe limitations.
AMD's energy-efficient PowerXpress5™ technology combines the low power ad-
vantages the integrated graphics processor with the performance of the discrete
graphics processor.
It switches the graphics operation between integrated graphics
and discrete graphics (depending on the power source and user preferences) without
the need to restart the computer. The
discrete (
high performance
) graphics proces-
sor (dGPU) can be used for graphic intensive applications under AC power
(plugged in to the power socket) and the integrated (Power Saving) graphics pro-
cessor (iGPU) to be used in battery mode when battery life needs extended, without
loss in performance.
