I do hope that this leads to improvement in the HIP/ROCm software ecosystem.

It’s definitely lacking in stability and polish compared to what NVIDIA has built. (Ask me why I’m on my third rebuild of LAMMPS this morning…)

HIP/ROCm is waaay better than it was a few years ago. It took a very long time, but AMD finally learned the importance of software.

Are consumer cards also benefiting from the improvements or only datacenters?

For me personally, blender uses ROCm and ROCm hiprt for Cycles tracing and cycles raytracing acceleration. I am using a Radeon RX 6800 and AMD Ryzen AI 7 350, and it works on Linux. ROCm HIPRT really does speed up cycles rendering (at the cost of more Vram usage). Of course, using the AMD driver on Linux, you get access to the system's RAM with GTT.
