Video Card
A equipment to output image or data to display device.
AGP
Accelerated Graphics port. The AGP is a slot specifically designed
for video and graphics - faster alternative to the PCI bus, which
is shared among many peripherals. The AGP allows graphics programs
to temporarily store large amount of data - for example, a texture
map - in the computer's system memory. The graphics card can then
use this memory as if it were its own, and thus to process files
larger than it otherwise could - this is called AGP texturing. The
speed at which the graphics card can access and use the information
stored in the AGP memory (referred to as AGP 2X or AGP 4X) determines
the speed of the output. This output can be further accelerated
through Fast Writes which enable even faster data transfer.
PCI
PCI is a self-configuring PC bus architecture designed by Intel.
PCI has gained wide acceptance.

Memory Interface
Connection between memory and other device. Wider connection makes
faster data transfer. 128-bit wide data bus can communicate faster
between memory and graphics engine than 64-bit wide data bus.
Graphic Engine
An engine which processes taking information from a 3D application
and display it as a final image.

3D Triangle peak
rate
Maximum number of triangles (portions of an image) drawn to the
frame buffer in one second. This is a common industry metric for
characterizing performance.
Peak Fill rate
Maximum speed at which your graphics card can render pixels onto
your screen - usually measured in millions of pixels per second.
The higher the fill rate, the better the performance.
Memory Bandwidth
Data-carrying capacity and is expressed in cycles per second or
Hertz (Hz). In the case of RAM, bandwidth is a function of its rated
speed and the size of its data path.
RAMDAC
Random Access Memory Digital-to Analog Converter. This portion of
microchip sits on VGA chipset and translates the digital representation
of a screenful of information into an analog signal that the monitor
can display. The faster the RAMDAC (measured in MHz), the higher
the screen refresh rates that the card will support at each given
resolution.
Maximum resolution
The highest the number of pixels which can be displayed on the screen.
PCI Express
Overview
PCI Express is the most significant update to PC architecture in
the past decade. PCI Express is a new I/O technology designed to
allow computer systems to scale to new levels of performance. The
underlying design of the PCI Express architecture differs completely
from that of the "classical" PCI bus. For one thing, PCI
Express uses a serial data transfer scheme, which allows for higher
clockspeeds. In addition to higher frequencies and bandwidth, it
offers many advantages over existing AGP/PCI architectures, including
simplified PCB routing, advanced power management, robust error
recovery, hot plugging and swapping, virtual channels and traffic
classes.
The advantages of PCI Express:
- PCI Express performs higher frequencies with two directional
links; one for upstream transfer and another is for downstream.
For PCI Express x16, each link consists of 16 lanes and each one
lane can provide 250MB/s. Moreover, if counting in both directions,
PCI Express X16 will get 8GB/sec.
- PCI Express offers significantly higher bandwidth in both the
upstream and downstream directions than AGP 8X. Furthermore, it
supports full duplex transfers (ie. both directions simultaneously),
while AGP can only support transfers in one direction at a time.
Note that this important capability is only supported in native
PCI Express design.

HDTV
High-definition television (HDTV) refers to the broadcasting of
television signals with a significantly higher resolution than traditional
formats (NTSC, SECAM, PAL) allow. The current HDTV standards are
defined as 1080 active interlaced or progressive lines, or 720 progressive
lines, using a 16 :9 aspect ration in ITU-R BT. 709.
Daul-link DVI
DVI cables send information using a digital information format called
TMDS (transition minimized differential signaling). Single-link
DVI uses a 165MHz transmitter to provide resolutions up to 1920x1080
at 60Hz. For higher resolution, starting with 1920x1080 at 85Hz
and upwards to 2048x1536 and 2560x1600 pixels, dual-link DVI is
required (two transmitters).
XHD
Extreme High Definition, or XHD, is achieved by using one or two
dual-link DVI ports. The higher bandwidth allows the cards to reach
a maximum resolution of 2560x1600. XHD cables provide far superior
video definition and the highest resolution video performance for
HDTV and today’s high-resolution signals. Cables include composite
video, S-Video, component video, VGA, DVI, HDMI, digital audio and
others.
