Last week NVIDIA quietly released the GeForce GT 520. Their new card is based on a new GeForce GF119 core that features 48 shaders and a 64-bit memory interface. The graphics processor is basically half a GF108 and looks like it is the smallest configuration imaginable for the Fermi architecture - it has only one SM and one GPC.
GeForce GT 520 is targeted at the entry-level market with OEMs and office system builders in mind. In terms of features GT 520 offers DirectX 11 which was not available on the GeForce 210 and GT 220 cards that have become quite old but are still available on the market. Power consumption of GeForce GT 520 is also expected to be lower than on previous generations. Just like older cards, GT 520 has support for NVIDIA's CUDA, PhysX, accelerated DVD/Blu-ray and Blu-ray 3D decode.
