PTX is a virtual ISA and the reason why ROCm is doomed to fail well beyond its horrendous bugs. ROCm produces hardware specific binaries which not only means you need to produce binaries for multiple GPUs but you also don’t have any guarantee for forward compatibility. A CUDA binary from 10 years ago will still run today on modern hardware, ROCm breaks compatibility between minor releases sometimes and it’s often not documented.
