Well, I was hoping for some quantitative benchmarks, the only conclusion from this posts is that HIP conversion tool is supposed to work 99.6% of times according to AMD.
> When running on CUDA, the ported HIP application uses a compilation, runtime, and library flow that is very similar to the original CUDA application. Thus, we would expect the HIP/CUDA application to deliver very similar performance as the original CUDA/CUDA app.
You'd expect? I don't know if I'd trust benchmarks AMD put out on this subject, but I'd trust them more than not even bothering to benchmark.
