Performance of Memory Copy between Host and Device with NVIDIA cards

Performance of NVIDIA Geforce 8600
  • CudaMemcpyHostToDev=18 microseconds
  • CudaMemcpyDevToHost=23 microseconds 

Performance of NVIDIA GTX 580
  • CudaMemcpyHostToDev=6 microseconds
  • CudaMemcpyDevToHost=8 microseconds

As we can see that NVIDIA new GPGPU cards like GTX series with FERMI memory architecture is much faster by itself than old NVIDIA crds like Geforce series.
