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.

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

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.

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

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