GPUs                       GeForce 8800 Architecture

 A quite revolution with
    plenty of potential

 Programming:
   - Brook
   - Cg
   - CUDA

 Bottleneck:GPU<->CPU

                                                          • 367 GFLOPS vs. 32 GFLOPS
                                                          • 86.4 GB/s vs. 8.4 GB/s

                                                          • Up to 10x is typical if kernels
                                                            have enough parallelism

                                                          • Up to 25x – 400x if a data,
                                                            control-flow suits the GPU*
