From Fermi to Kepler
Every two years or so, NVIDIA engineers set out to design a new GPU architecture. The architecture defines a GPU's building blocks, how they're connected, and how they work. The architecture is the basis not just for a single chip but a family of chips that serves a whole spectrum of systems, from high performance PCs to wafer thin notebooks, from medical workstations to supercomputers. It is the blueprint for every NVIDIA GPU for the next two years.
Just over two years ago, NVIDIA launched the Fermi architecture with the GeForce GTX 480. Named after the Italian nuclear physicist Enrico Fermi, this new architecture brought two key advancements. First, it brought full geometry processing to the GPU, enabling a key DirectX 11 technique called tessellation with displacement mapping. Used in games such as Battlefield 3 and Crysis 2, this technique greatly improves the geometric realism of water, terrain, and game characters. Second, Fermi greatly improved the GPU's performance in general computation, and today, Fermi GPUs power three out of the top five supercomputers in the world.
Today, NVIDIA is launching Kepler, the much anticipated successor to the Fermi architecture. With Kepler we wanted not only to build the world's fastest GPU, but also the world's most power efficient. Feature wise, we added new technologies that fundamentally improve the smoothness of each frame and the richness of the overall experience.
