Phoronix: Vulkan 1.3.226 Released With Mesh Shader Extension

Vulkan 1.3.226 is out this morning and to much excitement adds the VK_EXT_mesh_shader extension as cross-vendor functionality for mesh shaders!..

This bit is interesting:

It is important to note, that while portability between APIs can be achieved, portability in performance among vendors is much harder. This is one of the reasons why this extension has not been released as a ratified KHR extension and Khronos continues to investigate improvements to geometry rasterization.

Do You already have a feeling for the possible performance of mesh shaders with RADV on RDNA2 hardware?

I think mesh shading is a very low level tool which if you use it correctly can give you perf improvements if your app is bottlenecked by geometry throughput.

Otherwise, just because something uses mesh shaders does not mean it will be automatically faster.
