graphics and video processor, High Definition video decoder and supports
DDR3 1333 controller and USB 3.0 interface.
The VIA VX11H offers superb-graphics performance, immersive visual
experience, and supports DirectX 11.0 that allows realistic 3D rendering and
increased visual acuity. It is also based on a highly sophisticated power
efficient architecture that enables such rich integration into a compact package.
1.1.3. Modular Expansion Options
The VIA EPIA-M920 ensures long-term usability with its support for industry
standard expansion options. Its support for legacy PCI expansion cards helps
to smooth and reduce the costs of transitioning to newer expansion
technologies. The VIA EPIA-M920 enables companies to slowly roll out
upgrades as necessary instead of having to replace everything all at once. This
ensures that companies using the EPIA-M920 obtain the maximum benefits
from its past investments in PCI expansion cards.
The VIA EPIA-M920 also includes a 4-Lane PCI Express 2.0 expansion slot that
provides protection against obsolescence.
