G71 bandwidth counters

Hi,

I am trying to measure total GPU bandwidth to/from external memory on my Galaxy S8 using Streamline. The values I am getting by multiplying "Mali L2 Cache Beats Read/Write" by AXI bus width (16 bytes) seem quite low. Is this the correct approach? Do I need to factor in any of the other cache counters (Mali Tiler Bus, Mali Cache Texture, Mali Cache Load/Store etc)?

Best regards,

Pete

Thanks,
