Hi, I have access to a shared system (docker based) with a MI210 on it and ROCm 5.5.1 and 5.6. I was curious about the performance between the two versions. Ubuntu Jammy (22.04).

I am no expert on any of this, I just know enough to get some output and report back. I'd love for someone to take a look at these numbers and provide some analysis. If there is anything specific that I can do to help here, please let me know. It just takes a few minutes to spin up the compute resources.

I git cloned master, compiled everything, and after a whole bunch of compiler warnings, it built a binary and I ran:

./VkFFT_TestSuite -o output.txt -test

Hello,

Thank you for the results. There seems to be not that big of a difference between the two versions, but honestly I rarely expect improvements just from runtime updates - most improvements would come from low level optimizations of memory controllers of the GPU and the logic for this doesn't seem to change often, even between generations.

As for more detailed analysis of the results, I have benchmarks of MI250 in the VkFFT paper, if you are interested, I encourage you to check them.

Best regards,
Dmitrii
