of I/O and connectivity features, including two USB 3.0 ports, one Gigabit Ethernet port, one Mini HDMI
port, and one VGA port. The functionality of the VIA EPIA-P910 can be enhanced using its onboard pin
headers and a variety of expansion cards and modules.
The VIA EPIA-P910 includes one 1333MHz DDR3 SODIMM slot that support up to 8GB memory size, and
provides support for high fidelity audio with its included VIA VT2021 High Definition Audio codec. In
addition, it supports two SATA 3.0Gbps storage devices and fully compatible with Microsoft Windows
and Linux operating systems.
1.1. Key Features and Benefits
1.1.1. VIA Eden®X4 Processor
The VIA Eden®X4 is a 64-bit superscalar x86 multi-core processor combine on two dies. It is based on
advanced 28 nanometer process technology packed into an ultra-compact NanoBGA2 package measuring
21mm x 21mm. The VIA Eden®X4 processor delivers a superb performance on multi-tasking, multimedia
playback, productivity and internet browsing in a low power budget. In addition, it is ideal for most of
multi-display environment, and embedded system applications such as industrial PCs, test machines,
measuring equipment, digital signage, medical PCs, monitoring systems, gaming machines, in-vehicle
entertainment, etc.
1.1.2. VIA VX11H MSP Chipset
The VIA VX11H is the fourth generation, highly integrated Media System Processor which provides high
quality digital video streaming and high definition video playback. It features the VIA C-640 DX11 3D/2D
graphics and video processor, High Definition video decoder 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. The VIA VX11H is based on a highly
sophisticated power efficient architecture that enables such rich integration into a compact package.
1.1.3. Expansion Option
The VIA EPIA-P910 further proves its versatility by providing an optional expansion connector. The VIA
EPIA-P910-A I/O expansion card is connected through onboard pin headers carrying the front panel I/O
such as audio jack, USB 2.0 ports, LED indicator and power button.
The companies using the VIA EPIA-P910 with VIA EPIA-P910-A I/O expansion card obtain the maximum
benefits and enable to slowly roll out upgrades as necessary instead of having to replace everything all at
once.
