Github rocm points about a number of performance issues on gfx803 hardware. This issue seems to be present since 3.7.0, but never resolved. I made a few benchmarks of opencl performance on rocm - clover, rocm is > 10x slower compared to clover. Could you please insert rocm 3.5.0 ebuilds again? I know there's still on rocm github, I even created ebuilds for them myself. Reproducible: Always Steps to Reproduce: 1.compile rocm 2.run benchmark 3.uninstall rocm 4.compile clover 5.run benchmark Actual Results: rocm performance is 10x slower compared to clover, and the execution crashes frequently Expected Results: same performance, both should be running fine

please write cat/pkg always in the summary
(In reply to Jonas Stein from comment #4) > please write cat/pkg always in the summary I'm sorry, I wasn't sure about which package we are talking about: rocm consists of several packages, so not sure which one of them caused the regression.
GFX803 is no longer supported by ROCm, so it will fade away quickly. Guess it's better to run on amd proporietary unless clover makes a comeback
