The main attributes of the GPU are the core clock rate, which typically ranges from 250 MHz to 1200 MHz in modern cards.

This is the speed at an image can be rendered or "painted". This rate is specified in texels per second, the number of 3D pixels that can be painted per second. A texel is a pixel with depth (3D). The fill rate comes from the combined performance of the clock speed of the processor and the number of pixels it can process per clock cycle, and will tell you how quickly an image can be fully rendered on screen.

This impacts on the rendering capability of the GRU. The clock speed itself is not the critical factor. Rather it is the per-clock performance of the graphics processor, which is indicated by the number of pixels it can process per clock cycle.

The bit data rate between memory and the GPU.

VRAM was typically based on DDR technology. During and after that year, manufacturers moved towards the vastly superior DDR2, GDDR3 and GDDR4.

the video card will have its own video memory which is called Video RAM or VRAM. The VRAM capacity of most modern video cards range from 128 MB to 2.0 GB.

The memory clock rate in modern cards are generally between 400 MHz and 2.4 GHz.

Designed to meet the output protection management (HDCP) and security specifications of the Blu-ray Disc and HD DVD formats, allowing the playback of encrypted movie content on PCs when connected to HDCP-compliant displays. Requires other HDCP-compatible components.

Delivers advanced visual effects at unimaginable speeds. Full support for the latest Microsoft® DirectX® Shader Model enables stunning and complex special effects. Next-generation shader architecture with new texture unit design streamlines texture processing for faster and smoother gameplay.

The industry’s fastest antialiasing delivers ultra-realistic visuals, with no jagged edges, at lightning-fast speeds. Visual quality is taken to new heights through a new rotated grid sampling pattern, advanced 128 tap sample coverage, 16x anisotropic filtering, and support for transparent supersampling and multisampling.

Allows the user to adjust color controls digitally to compensate for the lighting conditions of their workspace, in order to achieve accurate, bright colors in all conditions.

The standard for today’s PCs and next-generation consoles enables stunning and complex effects for cinematic realism. NVIDIA GPUs offer the most complete implementation of the Shader Model feature set-including vertex texture fetch (VTF)-to ensure top-notch compatibility and performance for all DirectX applications.

Enables stunning and complex special effects. Next-generation shader architecture delivers faster and smoother gameplay.

Ensures top-notch compatibility and performance for OpenGL applications.

This is the minimum power supply wattage requirement for the graphics card to perform properly.

Generally referred to as a passive cooling device, it has no moving parts and, therefore, is soundless and very reliable; it absorbs and dissipates heat from the GPU using thermal contact (by either direct or radiant contact with a cooling medium such as air).

Included to allow the connection with DVD players, video recorders and video game consoles.

Maximum Horizontal Screen Resolution indicates the maxiumum possible sharpness and clarity of an image that a monitor can display, measured in number of dots (pixels) horizontally.

Maximum Vertical Screen Resolution indicates the maxiumum possible sharpness and clarity of an image that a monitor can display, measured in number of dots (pixels) vertically.

The RoHS Directive stands for "the restriction of the use of certain hazardous substances in electrical and electronic equipment". This Directive bans the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants.
