CUDA (aka Compute Unified Device Architecture) is a parallel computing platform and programming model created by NVIDIA and implemented by the graphics processing units (GPUs) that they produce. CUDA gives program developers direct access to the virtual instruction set and memory of the parallel computational elements in CUDA GPUs.

The category to which the graphics processor (GPU) belongs e.g. Southern Islands family of Radeon processors (made by AMD), GeForce 600 (made by NVIDIA).

Also known as a graphics processing unit (GPU), this 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. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are very efficient at manipulating computer graphics.

The clock rate is the fundamental rate in cycles per second (measured in hertz) at which a computer performs its most basic operations such as adding two numbers. There are more factors, like internal memory size, that influence a computer's actual response time.

The maximum number of pixels that can be displayed in the image. It is usually quoted as width × height,: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels.

Parallel processing technology is the simultaneous use of more than one CPU or processor core to execute a program or multiple computational threads. Ideally, parallel processing makes programs run faster because there are more engines (CPUs or Cores) running it. In practice, it is often difficult to divide a program in such a way that separate CPUs or cores can execute different portions without interfering with each other. Most computers have just one CPU, but some models have several, and multi-core processor chips are becoming the norm. There are even computers with thousands of CPUs.

The type of memory used by the video card. Often a combination of dedicated memory (Video RAM or VRAM) and dynamic system memory is used. UMA stands for Unified Memory Architecture, and is a computer memory architecture that allows the graphics processing unit to share system memory. Other abreviations: RAM = Random Access Memory, SDRAM = synchronous dynamic RAM, DDR = double-data-rate.

Hardware and software that connects the main memory to the memory controller in computer systems. Originally, general-purpose buses like VMEbus and the S-100 bus were used, but to reduce latency, modern memory buses are designed to connect directly to DRAM chips, and thus are designed by chip standards bodies such as JEDEC.

The frequency at which the memory (e.g. RAM) runs.

The number of sockets (ports) for HDMI connections. HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for existing analog video standards.

This is the amount of DVI-I interfaces. Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor. DVI-D means DVI digital, which means it can only support digital, but not analog.

Number of VGA (D-Sub) ports (connecting interfaces) in the device. The VGA (D-Sub) connector is a 15 pin connector between a computer and a monitor. It was first introduced in 1987 by IBM.

PPU (microprocessor) expansion card designed by Ageia to accelerate PhysX-enabled video games.

DirectX is a collection of APIs (application programming interfaces) for easily handling tasks related to game programming on the Microsoft Windows operating system.

A shader is a program used in 3D computer graphics to determine the final surface properties of an object or image. This can include arbitrarily complex descriptions of light absorption and diffusion, texture mapping, reflection and refraction, shadowing, surface displacement and post-processing effects. It is also used to refer to video graphics hardware units that run these programs.

OpenGL (Open Graphics Library) is a specification defining a cross-language cross-platform API for writing applications that produce 3D computer graphics (and 2D computer graphics as well). The interface consists of over 250 different function calls which can be used to draw complex three-dimensional scenes from simple primitives.

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection to prevent copying of digital audio and video content as it travels across connections.

A dual-link DVI interface sends data over both of the DVI links to the monitor, and this is how higher resolutions are achieved. With dual-link DVI, a resolution of 2048 x 1536 is possible.

Full High Definition (HD) means that a display supports a resolution of 1920 x 1080 pixel, and has a digital TV connection.

The method used to cool the device or to cool the air around the device.

Amount of power consumed by this model, often expressed in watts (W). Typical values that manufacturers give are power consumption when off, standby/suspended mode, typical use, maximum usage.

Windows vesions wich can be used with the device.

Mac operating systems e.g. OS X can be used with the device.

8 RT. Linux (9.4, 9.5), Red Hat Enterprise Linux 5.0 (supported with a pre-built package); SUSE Linux (10.3, 11.0, 11, 11.1, 11.2), Fedora (9, 9.0, 10, 10.0, 11.0, 11, 12, 12.0), Ubuntu (8.04, 8.04.1, 8.04.2, 8.10, 9.04, 9.10, 10.04), Debian (5.0, 5.0.1, 5.0.2, 5.0.3)
