GRAPHICS CARD

History of Graphics In 1983 Intel made the iSBX 275 Video Graphics Controller Multimodule Board for industrial systems based on the Multibus standard.

Released in 1985, the Commodore Amiga was one of the first personal computers to come standard with a GPU.

Nvidia was first to produce a chip capable of programmable shading, the GeForce 3(code named NV20).

Further,many more graphics cards were introduced like The Nvidia GeForce256(also known as NV10) the ATI Radeon 9700 (also known as R300), etc which have brought about a revolutionary change in graphics today!

What is a Graphic Card?-> “Visual center” of a computer's brain-> Outputs Images to the computer's display -> Incredibly powerful-> Perform a variety of useful functions, especially in the world of computer gaming.

Types Of Graphics Cards

Integrated Graphic cards:- • Built in to the motherboard• Serve Basic display functions• Also called On-Board Graphic cards

PCI Graphic cards:- • Use PCI Slot on motherboard• Older motherboards have PCI Slots• A little Out-of-date

Types Of Graphics CardsAGP Graphic cards:- • Connected with AGP port on motherboard• Have four speeds 1x,2x,4x and 8x• Faster than PCI cards

PCI-E Graphic cards:- • Use PCI-E Slot on motherboard

• Most advance and powerful cards• PCI-E graphics cards can be accelerated to 16 times

How graphic Cards works?

GPU calculates the position and

color of each onscreen pixel

Save visual data Sends it to the RAMDAC (digital

to analog converter) to output to

the monitor.

2. ATI

Produced by ADVANCE MICRO DEVICES (AMD).

Manufactures Graphics Cards and RAMs. Compete Nvidia by producing quality GPUs. It sells Radeon GPUs to third-party manufacturers, who build and sell the Radeon-based video cards to the OEM and retail channels.

Manufacturers of the Radeon cards include Sapphire

XFX Asus Gigabyte MSI HIS

S3 VIRGE• First 3D

graphics card

ATI RAGE PRO• First card to support agp 2x. • Integrated floating point set up engine to

generate 1.2 million triangles per second.

NVIDIA NV3

• Designed with Microsoft's DirectX 5 API in mind.

• 4MB of memory, a 100MHz core clockspeed, 1.6GB/s of bandwidth, a 206MHz RAMDAC, compatible with AGP 2X.

• It was also a 2D/3D combo card• 3.5 million transistors

INTEL i740

• Strengthened GMA (Graphics media accelerator)

ATI Rage Fury Maxx

• Two graphics chips

NVIDIA 3D Vision

NVIDIA 3D Vision technology delivers stereoscopic 3D images for gamers, movie-lovers and photo enthusiasts when configured with NVIDIA GPUs, NVIDIA 3D Vision active shutter glasses, and 3D Vision- Ready display.

Why graphics card is important ????

Very poor reflections

No glow in surrounding

Low Graphics of game without Graphics card :

Poor depth of field

Clear reflections

Glow in surrounding

High Graphics of game with Graphics card :

Clear depth of field

Advantages of Graphics Card :Motion Blur :

This technique is used to blur objects in fast motion.

3. Texture Mapping :

This technique allows addition of details on surfaces without adding complexity.

4. Lens flare :This technique allows producing lightning effect as similar as light emitting from light sources.

5. Fresnel Effect :

This technique allows us applying shadows and reflections over an object through different angles.

6. Anisotropic Filtering :

This technique enhances quality of textures at oblique viewing angles.

Poor texture quality

Detailed textures

7. PICTURES COMES TRUE :

High Definition effects can be added to images so that they looks like real photos.

Applications of Graphics card:

1.Paint Programs:

This allows you to create freehand drawing.

2.Creating 3D models using CAD software

3. For creating Animations :
