    Bidirectional PCIe performance on HD7970

    t-naka

      I tried "PCIe Speed Test v0.2" (AMD APP Power Toys) and BufferBandwidth (APP SDK samples) to get PCIe bandwidth.

      But these are single direction (CPU to GPU / GPU to CPU) performance.

      I heard HD7970 has 2 DMAs and it can do bidirectional access.

      Is there any tool or method to get bidirectional bandwidth on HD7970?
