The term VGA is also often used to refer to a screen resolution of 640 × 480, whatever the graphics card manufacturer is. The VGA card is useful for translating computer output to the monitor. For the graphic design process or playing a video game, a high-powered graphics card is required. Manufacturers of famous graphics cards include ATI and nVidia.
In addition, VGA can also refer to the 15-pin VGA connector which is still widely used to deliver analog video signals to the monitor. The VGA standard is officially superseded by the XGA standard from IBM, but in fact VGA is superseded by Super VGA.
The VGA Card function is to convert a digital signal from a computer into a graphical display on the monitor screen. The VGA card (Video Graphic Adapter) is useful for translating the computer output to the monitor. To draw / design graphics or to play games. VGA Card is often also called Card display, VGA card or graphics card. The embedded graphics card is called an expansion slot. Chipset / processor on the VGA card, so many kinds because each VGA card factory has its flagship Chipset. There are many manufacturers of VGA card chipsets like NVidia, 3DFX, S3, ATi, Matrox, SiS, Cirrus Logic, Number Nine (# 9), Trident, Tseng, 3D Labs, STB, OTi, and so on.
DRAM (Dynamic RAM) speed 80 ns or 70 ns, there is also MD-RAM (Multiple Dynamic RAM) that uses layered DRAM. DRAM is used on many 8, 16, or 32 bit graphics cards. The use of DRAM is for entry-level computers, which do not require high speed and large color. EDO RAM speed 60 ns to 35 ns, EDO RAM is mostly found on 64 bit graphics card. EDO RAM commonly used has 60 MHz 60 / 40ns speed. Examples of VGA cards that use EDO memory are WinFast S280 / S600 3D, Diamond Stealth 2000 3D, ATi Mach 64, etc. VRAM (Video RAM) speed 20 or 10 ns, VRAM is more expensive than DRAM because VRAM is faster than DRAM. The use of VRAM on a VGA card is intended for high-end computers. VRAM is usually installed on VGA which is concentrated for graphic design. Examples of VGA cards that use VRAM are Diamond Fire GL, Diamond Stealth 3000 3D, Diamond Stealth 64, etc. SGRAM (Synchronous Graphic RAM) speed is less than 10 ns, SGRAM on VGA card is also based on SDRAM technology on computer main memory. SGRAM is widely used on high grade graphics cards that have 3D accelerator capabilities. Examples of VGA cards that use SGRAM are Matrox MGA Millennium, Matrox Mystique 3D, Diamond Stealth II S220, Diamond Viper, ASUS 3D Explorer, ATI Rage II 3D Pro, RAMBUS RAM usage on VGA card computer is still small (RAMBUS is memory used on Nintendo gaming machines, Sega, so far only Creative Labs production graphics card (MA-302, MA-332 Graphic Blaster 3D and Graphic Blaster xXtreme) .
On a PC there are 3 components that play an important role in terms of graphics performance: processor, memory, and VGA cards. VGA (Video Graphics Adapter), is a standard analog computer display. VGA can also be interpreted as a component whose job is to generate visuals from computers and hardware that gives commands to the monitor to display the visual output we can see. VGA was first marketed in 1987 by IBM (International Bushiness Machines Corporation) shortened to IBM. IBM is one of the US companies that manufactures and manufactures hardware and software. IBM was founded on July 15, 1911 and operates in 1888 based in Armonk, New York, USA.
VGA consists of two types, namely: onboard VGA and VGA Card (with VGA card).
Onboard VGA
Onboard VGA is a processing unit that has been integrated into the motherboard, then the VGA card is not needed anymore. The existence of this onboard VGA chipset is not fixed because this onboard VGA can be set to inactive if the user wants to install the VGA card he wants.
Since IBM PC was born in 1981, almost all PCs have separate memory for frame buffers, which are memory blocks where the images that come out on the monitor screen are mapped. This is not a problem for systems that have monochrome video bebasis characters. Because the required frame buffer is only 2 KB. But a modern-based GUI (Graphical User Interface) that requires a high-resolution, bit-mapped screen and true color is greedy. The 640 x 480 pixel resolution screen with 8 bit color requests a frame buffer of 300 KB, while the 1024 x 768 pixel resolution screen with 24 bit color requires 2.25 MB of memory. The dedicated buffer frames are fixed-sized.
VGA Card (with VGA card)
Since the first IBM PC system, in the computer there must be a graphics card unit, whether it's CGA, EGA, MCGA, VGA, or something else. By using a VGA card instead of onboard it will get better performance than a system that uses UMA (Unified Memory Architecture). If an 8-bit graphic card with 512 KB of memory that can display 256 colors at 640 X 480 resolution is enough, then not anymore. The minimum requirement for a multimedia computer is a 64 bit graphics card with 1 MB of memory.
History of 3D Graphics Developments
Now that technology is getting more and more advanced, developers of GPU (Graphics Processing Unit) are starting to improve their ability to produce a good vga card. Here are some examples of vga cards from the first to the present:
S3 ViRGE
The extension of "ViRGE is Virtual Reality Graphics Engine", this vga is the first generation that has been using 3D graphics technology. S3 ViRGE has spec. 64-bit offers 4MB of onboard memory, core and memory clockspeeds up to 66 MHz, and also supports feature features such as Bilinear and Trilenear texture filtering, MIP mapping, Alpha blending, Z-buffering, and other 3D textures.
NVIDIA NV3
This VGA is the first artificial of Nvidia, this vga is also created with Microsoft's design technology DirectX 5 API. NVIDIA NV3 has a spec. 4 MB of memory, 100 MHz core clockspeeds, 1.6 GB / s bandwidth, 206 MHz RAMDAC and 2x AGP support.
NVIDIA GEFORCE 200 SERIES
This VGA has the latest chipset output from Nvidia successfully memaukkan 1.4 billion transistors into the GPU. This VGA is also the most powerful Nvidia series and powerful capabilities.
Graphic Accelerator Today's chipsets incorporate built-in 3D acceleration capabilities on VGA cards. In addition to the VGA card, there is now a computer supporting pheriperal called 3D accelerator. 3D accelerator functions to process / translate data / 3D images more perfectly. 3D accelerators whose existence does not require an IRQ are capable of manipulating complex 3D graphics. For example in 3D games can be displayed a much more realistic image. For many of the 3D graphics processing functions that were once performed by the processor on the motherboard, is now done by 3D graphics processor on the 3D accelerator. With this division of labor then the processor can do more processing work more. In addition programmers do not need to create 3D graphics function, because the function has been provided by 3D accelerator. The 3D chipset on the VGA card is not as good as if you were using 3D accelerator as a supporter (3D accelerator installed separately along with VGA card). Even so the 3D Chipset on VGA card also supports 'some' 3D acceleration facility on 3D accelerator. As an important note that, the 3D accelerator function will be optimal if the software / games are run using special functions in the 3D accelerator. Software / games that support this facility began to grow, which is well known is the support for 3D accelerator that has a VooDoo 3D FX chipset, Rendition Verite, and 3D Labs Permedia.
This vga card can be used by installing on the vga slot, this type of vga is rarely used, because of the limitations of the features, the features are the slots on the front there are coakan, and the type of pin is straight vertically.
VGA AGP
The beginning of vga agp, due to the significant increase of data transfer from memory, cpu to display equipment, so that made agp slot to install vga agp type, vga agp was launched based on voltage values used, namely agp 1x and 2x with voltage 3.3 v, while 4x and 8x 1.5 volt. The last vga agp that appeared was a pro and universal pro type with 3.3 and 1.5 volt capabilities. The features of this vga is the shape of its vertical pin with a shape similar to a honeycomb formation.
VGA PCI EXPRESS
The development of the next pci slot has a remarkable ability, with the name PCI Express, designed to install cutting-edge equipment, the 2 well-known PCI Express slot versions are PCI Express 1 x and 16 x, PCI Express 16x is specifically used to install vga type PCI Express, and 1x for the purpose of installing additional equipment. Physical characteristics of vga pci express type is to see the shape that has the opposite form of ordinary PCI.
With the existence of VGA that develop from time to time, it can be concluded:
On a PC there are 3 components that play an important role in terms of graphics performance: processor, memory, and VGA cards.
VGA consists of two types, namely: onboard VGA and VGA Card (with VGA card).
Onboard VGA is a processing unit that has been integrated into the motherboard.
VGA Card is a processing unit that does not converge on the motherboard.
In addition to the VGA card, there is now a computer supporting pheriperal called 3D accelerator.
Compared with VGA Card, the advantages of 3D accelerator function to process / translate data / 3D images more perfectly.
maybe so much that i can say about the history and development of vga
