I need your help. I create an OpenCL program using pinned buffer.
The duration to transfer buffer from device to host is fast as I expected.
My question is, is it normal if the transfer rate of pinned buffer (size is 256 MB) exceed the PCI-e bandwidth (PCI-e 2.0 x 16)??
The transfer rate of pinned buffer is 204582 GB/s ( iget the transfer rate from AMD APP Profiler)
