A graphics card is a computer expansion card that generates a feed of graphics output to a display device such as a monitor. Graphics cards are sometimes called discrete or dedicated graphics cards to emphasize their distinction to integrated graphics processor on the motherboard or the CPU. A graphics processing unit (GPU) that performs the necessary computations is the main component in a graphics card, but the acronym "GPU" is sometimes also used to erroneously refer to the graphics card as a whole.
A framebuffer is a portion of random-access memory (RAM) containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame. Modern video cards contain framebuffer circuitry in their cores. This circuitry converts an in-memory bitmap into a video signal that can be displayed on a computer monitor.
ATI Technologies Inc., commonly called ATI, was a Canadian semiconductor technology corporation based in Markham, Ontario, that specialized in the development of graphics processing units and chipsets. Founded in 1985, the company listed publicly in 1993 and was acquired by AMD in 2006. As a major fabrication-less or fabless semiconductor company, ATI conducted research and development in-house and outsourced the manufacturing and assembly of its products. With the decline and eventual bankruptcy of 3dfx in 2000, ATI and its chief rival Nvidia emerged as the two dominant players in the graphics processors industry, eventually forcing other manufacturers into niche roles.
3Dlabs was a fabless semiconductor company. It was founded by Yavuz Ahıska and Osman Kent in 1994 with headquarters in San Jose, California. It originally developed the GLINT and PERMEDIA high-end graphics chip technology that was used on many of the world's leading computer graphics cards in the CAD and DCC markets, including its own Wildcat and Oxygen cards.
The DECstation was a brand of computers used by DEC, and refers to three distinct lines of computer systems—the first released in 1978 as a word processing system, and the latter two both released in 1989. These comprised a range of computer workstations based on the MIPS architecture and a range of PC compatibles. The MIPS-based workstations ran ULTRIX, a DEC-proprietary version of UNIX, and early releases of OSF/1.
Released in August 1997 by Nvidia, the RIVA 128, or "NV3", was one of the first consumer graphics processing units to integrate 3D acceleration in addition to traditional 2D and video acceleration. Its name is an acronym for Real-time Interactive Video and Animation accelerator.
Weitek Corporation was an American chip-design company that originally focused on floating-point units for a number of commercial CPU designs. During the early to mid-1980s, Weitek designs could be found powering a number of high-end designs and parallel-processing supercomputers.
The S3 ViRGE (Video and Rendering Graphics Engine) graphics chipset was one of the first 2D/3D accelerators designed for the mass market.
S3 Graphics, Ltd. was an American computer graphics company. The company sold the Trio, ViRGE, Savage, and Chrome series of graphics processors. Struggling against competition from 3dfx Interactive, ATI and Nvidia, it merged with hardware manufacturer Diamond Multimedia in 1999. The resulting company renamed itself to SONICblue Incorporated, and, two years later, the graphics portion was spun off into a new joint effort with VIA Technologies. The new company focused on the mobile graphics market. VIA Technologies' stake in S3 Graphics was purchased by HTC in 2011.
PowerVR is a division of Imagination Technologies that develops hardware and software for 2D and 3D rendering, and for video encoding, decoding, associated image processing and DirectX, OpenGL ES, OpenVG, and OpenCL acceleration. PowerVR also develops AI accelerators called Neural Network Accelerator (NNA).
The Tseng Labs ET4000 was a line of SVGA graphics controller chips during the early 1990s, commonly found in many 386/486 and compatible systems, with some models, notably the ET4000/W32 and later chips, offering graphics acceleration. Offering above average host interface throughput coupled with a moderate price, Tseng Labs' ET4000 chipset family were well regarded for their performance, and were integrated into many companies' lineups, notably with Hercules' Dynamite series, the Diamond Stealth 32 and several Speedstar cards, and on many generic boards.
Cirrus Logic Inc. is an American fabless semiconductor supplier that specializes in analog, mixed-signal, and audio DSP integrated circuits (ICs). Since 1998, the company's headquarters have been in Austin, Texas.
Oak Technology (OAKT) was an American supplier of semiconductor chips for sound cards, graphics cards and optical storage devices such as CD-ROM, CD-RW and DVD. It achieved success with optical storage chips and its stock price increased substantially around the time of the tech bubble in 2000. After falling on hard times, in 2003 it was acquired by Zoran Corporation.
Rendition, Inc., was a maker of 3D computer graphics chipsets in the mid to late 1990s. They were known for products such as the Vérité 1000 and Vérité 2x00 and for being one of the first 3D chipset makers to directly work with Quake developer John Carmack to make a hardware-accelerated version of the game (vQuake). Rendition's major competitor at the time was 3Dfx. Their proprietary rendering APIs were Speedy3D and RRedline.
HyperMemory was a brand for ATI's method of using the motherboard's main system RAM as part of or all of the video card's framebuffer memory on their line of Radeon video cards and motherboard chipsets. It relies on new fast data transfer mechanisms within PCI Express.
ALi Corporation is a major designer and manufacturer of embedded systems integrated circuits, and a former manufacturer of personal computer integrated circuits. It is based in Taiwan, and is a subsidiary of the Acer group.
The ATI Mach line was a series of 2D graphics accelerators for personal computers developed by ATI Technologies. It became an extension to the ATI Wonder series of cards. The first chip in the series was the ATI Mach8. It was essentially a clone of the IBM 8514/A with a few notable extensions such as Crystal fonts. Being one of the first graphics accelerator chips on the market, the Mach8 did not have an integrated VGA core. In order to use the first Mach8 coprocessor cards, a separate VGA card was required. This increased the cost of ownership as one had to purchase two rather than one expansion card for graphics. A temporary solution was presented with the ATI Graphics Ultra/Vantage cards, which combined an ATI 8514 Ultra and VGA Wonder+ into a single card. The Mach32 chip was the follow-up to the Mach8, which finally featured an integrated VGA core, true colour support and a 64-bit datapath to internal memory.
The Intel 810 chipset was released by Intel in early 1999 with the code-name "Whitney" as a platform for the P6-based Socket 370 CPU series, including the Pentium III and Celeron processors. Some motherboard designs include Slot 1 for older Intel CPUs or a combination of both Socket 370 and Slot 1. It targeted the low-cost segment of the market, offering a robust platform for uniprocessor budget systems with integrated graphics. The 810 was Intel's first chipset design to incorporate a hub architecture which was claimed to have better I/O throughput and an integrated GPU, derived from the Intel740.
The Voodoo2 is a set of three specialized 3D graphics chips on a single chipset setup, made by 3dfx. It was released in February 1998 as a replacement for the original Voodoo Graphics chipset. The card runs at a chipset clock rate of 90 MHz and uses 100 MHz EDO DRAM, and is available for the PCI interface. The Voodoo2 comes in two models, one with 8 MB RAM and one with 12 MB RAM. The 8 MB card has 2 MB of memory per texture mapping unit (TMU) vs. 4 MB on the 12 MB model. The 4 MB framebuffer on both cards support a maximum screen resolution of 800 × 600, while the increased texture memory on the 12 MB card allows more detailed textures. Some boards with 8 MB can be upgraded to 12 MB with an additional daughter board.
Actix Systems, Inc., was an American graphics adapter manufacturer active from 1990 to 1998 and based in the San Francisco Bay Area. The company was founded by Stephen W. Cheng and initially specialized in a subset of graphics adapters known as GUI accelerators, becoming a major player in the field. Toward the mid-1990s the company began manufacturing more general-purpose adapters under their GraphicsEngine brand.
