Nvidia product lines

GeForce
GeForce is a brand of graphics processing units (GPUs) designed by Nvidia. As of the GeForce 20 series, there have been fifteen iterations of the design.

With respect to discrete GPUs, found in add-in graphics-boards, Nvidia's GeForce and AMD's Radeon GPUs are the only remaining competitors in the high-end market. Along with its nearest competitor, the AMD Radeon, the GeForce architecture is moving toward general-purpose graphics processor unit (GPGPU). GPGPU is expected to expand GPU functionality beyond the traditional rasterization of 3D graphics, to turn it into a high-performance computing device able to execute arbitrary programming code in the same way a CPU does, but with different strengths (highly parallel execution of straightforward calculations) and weaknesses (worse performance for complex decision-making code).

Quadro
Quadro is Nvidia's brand for graphics cards intended for use in workstations running professional computer-aided design (CAD), computer-generated imagery (CGI), and digital content creation(DCC) applications.The GPU chips on Quadro-branded graphics cards are identical to the ones used on GeForce-branded graphics cards. The end products (i.e. the graphics card) differ substantially in their provided graphics device drivers and available professional support for the software.

Tesla
Tesla is Nvidia's brand name for their products targeting stream processing or general-purpose GPU. Products use GPUs from the G80 series onward. The underlying Tesla microarchitecture of the GPUs and the Tesla product line are named after pioneering electrical engineer Nikola Tesla.
