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.

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.

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-I is DVI integrated, which means it can support digital and analog.

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.

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.

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

The lowest RAM (memory) required to run a computer program or operating system.

Product can be used with Apple Mac software and/or hardware.
