The Tesla K20 family of GPU accelerators are among the highest performance, most efficient accelerators ever built. Based on the Nvidia Kepler compute architecture, the product family includes the Tesla K20X accelerator, the new flagship of the Tesla product line.
The Tesla K20X GPU accelerator can speed up applications by up to 10x when paired with leading CPUs. It features the new GK110 GPU with 2,688 cores, 3.95 teraflops single-precision and 1.31 teraflops double-precision peak processing capability, 6GB of on-board memory, and a memory bandwidth of 250GB/s. The Tesla K20 accelerator delivers more than 3.52 teraflops of single-precision and 1.17 teraflops of double-precision peak performance.
Both accelerators are powered by Nvidia CUDA, the parallel computing platform and programming model, and take advantage of innovative technologies like Dynamic Parallelism and Hyper-Q to boost performance and power efficiency.
