Comparison of Nvidia graphics processing units

The fields in the table listed below describe the following:

Model - The Marketing name for the processor assigned by NVIDIA.
Year - Year of release for the processor.
Code Name - The internal engineering codename for the processor (typically designated by an NVXY name and later GXY where X is the series number and Y is the schedule of the project for that generation.
Fab - Fabrication Process. Average feature size of components of the processor.
Bus interface - Bus by which the Graphics processor is attached to the system (typically an expansion slot, such as PCI, AGP, or PCI-Express).
Memory max - The maximum amount of memory used by the processor.
Core Clock max - The maximum factory core clock frequency (used as some manufacturers adjust clocks lower and higher, this number will always be the reference clocks used by NVIDIA).
Memory Clock max - The maximum factory effective memory clock frequency (used as some manufacturers adjust clocks lower and higher, this number will always be the reference clocks used by NVIDIA). All DDR/GDDR memories operate at half this frequency.
Config Core - The layout of the graphics pipeline, in terms of functional units. Over time the number, type and variety of functional units in the GPU core has changed significantly; before each section in the list there is an explanation as to what functional units are present in each generation of processors. In later models, Shaders are integrated into a Unified Shader Architecture, where any one shader can perform any of the functions listed.
Fillrate - Maximum theoretical fillrate in Textured Pixels per second. This number is generally used as a "maximum throughput number" for the GPU and generally, a higher fillrate corresponds to a more powerful (and faster) GPU.
Memory Subsection
Bandwidth max - Maximum theoretical bandwidth for the processor at factory clock with factory bus width. GB=10^9 bytes.
Bus Type - Type of memory bus or buses utilized.
Bus Width - Maximum Bit width of the memory bus or buses utilized. This will always be a factory bus width.
Graphics Library Support Section
DirectX - Maximum version of Direct3D fully supported.
OpenGL - Maximum version of OpenGL fully supported.
Features - Additional features that are not standard as a part of the two Graphics libraries.
