Graphics card or video card isdisplay adaptor or hardware

component whose function is to

generate output images to display.

It is also called as dedicatedexpansion card.

1. GPU Graphics Processing Unit :

A GPU is dedicated graphics

processor optimized for floating

point calculations which are

fundamentals to 3D graphics

rendering.


8/38

2. Video Bios :

The VIDEO BIOS or FIRMWARE

contains basic programs that governs

graphics card operations and provides the

instructions so that computer hardware

and software can interact with card.

It contains information on memory

timing, voltage of graphics processor andRAM, operating speed and other

information.

Like our motherboard BIOS, it is

possible to change VIDEO BIOS of our

graphics card, but it is recommended thatit should be done under experts

supervision, since changing VIDEO BIOS

may improve your graphics cards graphics

performance.

3. RAMDAC :

RAMDAC is Random access

Memory Digital To Analog Convertor which

converts digital signal to analog signal for use

by computer display which uses analog input

such as CRT display.

4. Motherboard Interface :It is the connection system which

connects graphics card with

motherboard system.

Although there are many connection

system since 1974.Nowdays AGP and

PCI-Express slot are most widely used

connection system.

5. Cooling Devices:

Graphics card uses lot of electricity

which is converted into heat. If heat

isnt dissipated then card could get

overheated and get damaged. Cooling

devices are incorporated to transfer

heat elsewhere.

6. Outputs:

These are the connection system which connects graphics card with

display.

1. VGA (D-sub): Analog based standard adopted in 1980s designed for CRT displays.Also called as VGA connector.

2.. S-Video : Analog.Commonly known as

S-Video, Super-video and Y/C.

Usually carries SD video.

Typically used in older TVs

3. DVI: Digital. Digital VisualInterface. Standard designed forflat panel screens such asplasma, LCD display, HDTV,video projectors,etc.

4. HDMI :Digital. High-Definition Multimedia Interface.

Used in TVs, Monitors etc.Carries Audio and Video.

5. DisplayPort : DisplayPort is a digital display interfacedeveloped by the Video Electronics Standards Association (VESA).The interface is primarily used to connect a video source to a

display device such as a computer monitor, though it can also beused to transmit audio, USB, and other forms of data. VESAdesigned it to replace VGA, DVI, and FPD-Link. Backwardcompatibility to VGA and DVI by using active adapter donglesenables users to use DisplayPort fitted video sources withoutreplacing existing display devices.DisplayPort ports can be made so that they are compatible with

single-link DVI and HDMI 1.4. Compatibility is achieved withDisplayPort Dual-mode ports, which are marked with the ++DP

logo, using attached passive adapters; powered active adapters

allow signal conversion to dual-link DVI and analog VGA. For

manufacturers DisplayPort has an advantage over HDMI in that it is

royalty-free, while there is an annual charge and a royalty fee for

HDMI.

OpenGL

OpenGL: Open Graphics Library

Cross-language, Multi-platformAPI for rendering 2D and 3Dcomputer graphics. The API is typically used to interact witha GPU, to achieve hardware-accelerated rendering. OpenGL

was developed by Silicon Graphics Inc. and widely used inCAD, virtual reality, scientific visualization, informationvisualization, flight simulation, and video games. OpenGL ismanaged by the non-profit technology consortiumKhronosGroup.

GPGPU

General-Purpose computing on Graphics ProcessingUnits is the utilization of a GPU (which typically handlescomputation only for computer graphics), to perform computationin applications traditionally handled by the CPU

DirectCompute Microsoft DirectCompute wich is a part of the Microsoft DirectX

collection and is an API that supports GPGPU on Windows operatingsystems.

CUDA, OpenCL, Stream

CUDA: nVidia

FireStream : AMD OpenCL: Open Standard (mainly used in AMD)

Usually GPUs have many Cores unlike CPUs. CPUs has few but powerfulcores (2, 4 etc) and GPUs has Hundreds of less powerful cores. This makes

certain operations are more efficient in GPUs than in CPUs.(CPUs better for Scalar operations, GPUs better for Vector operations)

Typical Core i5 CPUs has 2 or 4 cores

A mid range nVidia GPU has more than 96 CUDA Cores

A mid range AMD GPU has more than 400 Stream Processors +ROP Units and Texture Units

AMD and nVidia uses different techniques

nVidia uses less number of Powerful cores

AMD uses huge number of less powerful cores
