Introduction
Features
DDR3
DDR3 delivers increased system bandwidth and improved performance. It offers
peak data transfer rate of up to 17 Gb/s bandwidth. The advantages of DDR3
are its higher bandwidth and its increase in performance at a lower power than
DDR2.
Graphics
The Intel northbridge chip comes integrated with the Intel Graphics Media Ac-
celerator 4500 delivering an excellent blend of graphics performance and features
to meet business needs. With support for Microsoft DirectX 10, Shader Model 4.0
and OpenGL* 2.1, Intel GMA 4500 delivers excellent video and 3D graphics with
outstanding graphics responsiveness. These enhancements deliver the perfor-
mance and compatibility needed for today’s and tomorrow’s business applications.
PCI Express
PCI Express is a high bandwidth I/O infrastructure that possesses the ability to
scale speeds by forming multiple lanes. The x4 PCI Express lane supports trans-
fer rate of 1 Gigabyte per second. The PCI Express architecture also provides a
high performance graphics infrastructure by enhancing the capability of a x16 PCI
Express lane to provide 4 Gigabytes per second transfer rate.
Audio
The Realtek ALC262 audio codec provides 2-channel High Definition audio output.
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital audio sig-
nals to a device without having to be converted first to an analog format. This
prevents the quality of the audio signal from degrading whenever it is converted
to analog. S/PDIF is usually found on digital audio equipment such as a DAT
machine or audio processing device. The S/PDIF connector on the system board
sends surround sound and 3D audio signal outputs to amplifiers and speakers
and to digital recording devices like CD recorders.
