nVidia is best known as the maker of heavy duty GPUs although most know about their mobile product Tegra (and the components that go into it). Between these two items nVidia has a very good product portfolio. However, nVidia has not always been limited to GPUs and SoCs. At one time they also developed and manufactured their own Chipsets. These were required to utilize SLI (Scalable Link Interface) that has its roots from 3dfx which nVidia grabbed when they bought the latter. nVidia’s chipset business did not last that long due to a number of reasons and they were eventually forced to let it drop and instead license the right to use SLI out to other companies.
