I would like to know the exact profiling result for GPU bandwith value.
I am profiling GPU Read Total and Write GPU Memory Stats on GFXBench tests.
However, the values of Read and Write data are different depending on "Sample Freq".
The default Sample Freq is 50ms. With 50ms, Read and Write Memory Stats are smaller than 100/500/1000ms.
I am just wondering it is just simply tool bug. Or, there is another calculation process inside.
Which value should I trust from the Profiler? With 50ms Sample Freq or the others?
Please give me some information, huge curiosity I have.
Thanks in adavance.
