VIA EPIA-PX Overview
The VIA EPIA-PX Pico-ITX Mainboard is an ultra compact native x86 platform optimized for
today's demanding embedded and productivity applications. The mainboard is based on the
VIA VX700 advanced all-in-one system processor featuring an embedded hardware MPEG-2,
MPEG-4 and WMV9 video decoding accelerator. Its integrated VIA UniChrome™ Pro II
2D/3D graphics provide rich digital media performance. With the sizable memory
bandwidth of DDR2 533MHz SDRAM DIMM and the high data transfer speeds of ATA-133
and further enhanced by support of 8-Channel High Definition Audio Codec for Smart 7.1
surround sound and SPDIF, the VIA EPIA-PX delivers the increased performance levels
required by today’s embedded digital media applications.
