OpenCL – Maximum version of OpenCL fully supported.OpenGL – Maximum version of OpenGL fully supported.Direct3D – Maximum version of Direct3D fully supported.Bus width – Maximum bit width of the memory bus or buses used.Bus type – Type of memory bus or buses used.Bandwidth – Maximum theoretical bandwidth for the processor at factory clock with factory bus width.This number is generally used as a maximum throughput number for the GPU and generally, a higher fill rate corresponds to a more powerful (and faster) GPU. Fillrate – Maximum theoretical fill rate in textured pixels per second.In later models, shaders are integrated into a unified shader architecture, where any one shader can perform any of the functions listed. 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. Core config – The layout of the graphics pipeline, in terms of functional units.All DDR/GDDR memories operate at half this frequency, except for GDDR5, which operates at one quarter of this frequency. Memory clock – The factory effective memory clock frequency (while some manufacturers adjust clocks lower and higher, this number will always be the reference clocks used by Nvidia).Core clock – The factory core clock frequency while some manufacturers adjust clocks lower and higher, this number will always be the reference clocks used by Nvidia.

SM Count – Number of streaming multiprocessors.

Memory – The amount of graphics memory available to 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).

Average feature size of components of 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).

Launch – Date of release for the processor.

Model – The marketing name for the processor, assigned by The Nvidia.
