With the world’s first teraflop many-core processor, the NVIDIA® Tesla™ S1070 computing system speeds the transition to energy-efficient parallel computing. With 960 processor cores and a standard C compiler that simplifies application development, Tesla S1070 scales to solve the world’s most important computing challenges—more quickly and accurately.
Under the hood the S1070 has the same computational capacity as 4 C1060 cards. The S1070 does not actually run an operating system. It only houses and powers the GPUs. The device needs to be connected to a host system via two PCIe 2.0 connector cables.
