HyperMemory

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. [1] [2] [3]

However, to make up for the inevitably slower system RAM with a video card, a small high-bandwidth local framebuffer is usually added to the video card itself under Game or Graphic environment. This can be noted by the one or two small RAM chips on these cards, which usually have a 32-bit or 64-bit bus to the GPU. This small local memory caches the most often needed data for quicker access, somewhat remedying the inherently high-latency connection to system RAM.

The local and system memory areas are not noticeably separate to the user and often HyperMemory solutions are advertised as having as much as 4096 MB RAM when this is actually referring to the potential use of system RAM.

HyperMemory offers significant cost reduction to low-end video cards because of the reduction in trace complexity on the video card PCB, and a reduction in the amount of RAM needed on the card. The solution offers excellent performance for 2D acceleration tasks while also maintaining adequate memory speed capable of playing some modern 3D game titles with reduced quality. A video card with HyperMemory typically is slower in 3D benchmarks than a similar video card which has its own discrete video memory.

Video cards implemented with HyperMemory usually bore the HM or LE suffix, for further details, see ATI Video Card Suffixes.

Accelerated Graphics Port expansion bus

The Accelerated Graphics Port (AGP) was designed as a high-speed point-to-point channel for attaching a video card to a computer system, primarily to assist in the acceleration of 3D computer graphics. It was originally designed as a successor to PCI-type connections for video cards. Since 2004, AGP has been progressively phased out in favor of PCI Express (PCIe); by mid-2008, PCI Express cards dominated the market and only a few AGP models were available, with GPU manufacturers and add-in board partners eventually dropping support for the interface in favor of PCI Express.

A video card is an expansion card which generates a feed of output images to a display device. Frequently, these are advertised as discrete or dedicated graphics cards, emphasizing the distinction between these and integrated graphics. At the core of both is the graphics processing unit (GPU), which is the main part that does the actual computations, but should not be confused with the video card as a whole, although "GPU" is often used to refer to video cards.

HyperTransport (HT), formerly known as Lightning Data Transport (LDT), is a technology for interconnection of computer processors. It is a bidirectional serial/parallel high-bandwidth, low-latency point-to-point link that was introduced on April 2, 2001. The HyperTransport Consortium is in charge of promoting and developing HyperTransport technology.

GeForce is a brand of graphics processing units (GPUs) designed by Nvidia. As of the GeForce 20 Super series, there have been sixteen iterations of the design. The first GeForce products were discrete GPUs designed for add-on graphics boards, intended for the high-margin PC gaming market, and later diversification of the product line covered all tiers of the PC graphics market, ranging from cost-sensitive GPUs integrated on motherboards, to mainstream add-in retail boards. Most recently, GeForce technology has been introduced into Nvidia's line of embedded application processors, designed for electronic handhelds and mobile handsets.

Framebuffer portion of RAM containing a bitmap that drives a video display

A framebuffer is a portion of random-access memory (RAM) containing a bitmap that drives a video display. It is a memory buffer containing a complete frame of data. 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 Canadian technology corporation

ATI Technologies Inc. was a semiconductor technology corporation based in Markham, Ontario, Canada, that specialized in the development of graphics processing units and chipsets. Founded in 1985 as Array Technology Inc., the company listed publicly in 1993. Advanced Micro Devices (AMD) acquired ATI 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.

Graphics processing unit specialized electronic circuit; graphics accelerator

A graphics processing unit (GPU) is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are very efficient at manipulating computer graphics and image processing. Their highly parallel structure makes them more efficient than general-purpose central processing units (CPUs) for algorithms that process large blocks of data in parallel. In a personal computer, a GPU can be present on a video card or embedded on the motherboard. In certain CPUs, they are embedded on the CPU die.

The RIVA TNT, codenamed NV4, is a 2D, video, and 3D graphics accelerator chip for PCs that was manufactured by Nvidia. It was released in mid-1998 and cemented Nvidia's reputation as a worthy rival within the developing consumer 3D graphics adapter industry. The first RIVA TNT based card was released on June 15, 1998 by STB Systems: Velocity 4400. RIVA is an acronym for Real-time Interactive Video and Animation accelerator. The "TNT" suffix refers to the chip's ability to work on two texels at once.

RIVA TNT2 graphics processing unit

The RIVA TNT2 is a graphics processing unit manufactured by Nvidia starting in early 1999. The chip is codenamed "NV5" because it is the 5th graphics chip design by Nvidia, succeeding the RIVA TNT (NV4). RIVA is an acronym for Real-time Interactive Video and Animation accelerator. The "TNT" suffix refers to the chip's ability to work on two texels at once. Nvidia removed RIVA from the name later in the chip's lifetime.

Gaming computer personal computer designed for playing video games

A gaming computer, also known as a gaming PC or gaming rig, is a personal computer designed for playing video games that require a high amount of computing power. A modern gaming computer is comparable to a mainstream computer with the addition of performance-oriented components, such as high-performance video cards and high core-count central processing units. Gaming computers are often associated with enthusiast computing due to an overlap in interests; however, while a gaming computer is built to achieve performance for actual gameplay, enthusiast PCs are built to maximize performance, using games as a real application benchmark. Whereas enthusiast PCs are high-end by definition, gaming PCs can be subdivided into low-end, mid-range, and high-end markets. Video card manufacturers earn the bulk of their revenue from their low-end and mid-range offerings.
