Just in time for Vulkan tg to be faster in almost all situations, and Vulkan pp to be faster in many situations with constant improvements on the way, making ROCm obsolete for inference.
The advantages for ROCm would be integration into existing codebases/engineer skillsets (e.g. porting an existing C++ implementation of something to the GPU with a few attributes and API calls rather than rewriting the core kernel in something like GLSL and all the management vulkan implies).
