What's the difference between nVidia geforce video cards and other brands that make geforce cards?

GeForce is an Nvidia brand for their GPUs. Nvidia does not typically manufacture video cards for desktop PCs but others use their GPUs as the foundation for graphics cards. So when you see other cards using that brand name it means that the GPU was made by Nvidia.





Of course Nvidia doesn't actually have a factory to make semiconductor devices so the GPU was actually made somewhere else but designed by Nvidia (I think TSMC actually makes most of their devices).
