NVIDIA Corporation began as an American technology company based in Santa Clara, California. Nvidia designs graphics processing units (GPUs) for the gaming market, as well as system on a chip units (SOCs) for the mobile computing and automotive market. Nvidia's primary GPU product line, labeled "GeForce", is in direct competition with Advanced Micro Devices' (AMD) "Radeon" products. Nvidia expanded its presence in the gaming industry with its handheld SHIELD Portable, SHIELD Tablet, and SHIELD Android TV.

First product GeForce 256 Announced on August 31, 1999 and released on October 11, 1999. It offered a notably large leap in 3D gaming performance and was the first fully Direct 3D 7-compliant 3D accelerator. GeForce 256 was marketed as "the world's first 'GPU', or Graphics Processing Unit", a term Nvidia defined at the time as "a single-chip processor with integrated transform, lighting, triangle setup/clipping, and rendering engines that is capable of processing a minimum of 10 million polygons per second."

Latest product GeForce GTX TITAN X Launched March 17, 2015. This card has 8000 transistors in it. Bus interface PCIe 3.0. x16 Memory 12288Mb (12Gb) Bus type GDDR5. Release price 999$

Mobile GPUs Since the GeForce2, Nvidia has produced a number of graphics chipsets for notebook computers under the GeForce Go branding. Most of the features present in the desktop counterparts are present in the mobile ones. These GPUs have a lower power consumption but perform worse than their desktop counterpart. Beginning with the GeForce 8 series, the GeForce Go brand was discontinued and the mobile GPUs were integrated with the main line of GeForce GPUs, but their name suffixed with an M.
