We have Bercon noise support for the V-Ray GPU Next.
Procedural textures require separate implementation for GPU, and V-Ray GPU supports quite a lot (Forest Color, Multitexture, Bercon Noise, etc).
I don’t think there will be any additional procedural textures in the GPU for the official release unfortunately. Rewritting every procedural texture for GPU however is not really doable.
I know it’s not ideal, but as an annoying workaround you could always make a bunch of them at different sizes in Adv CPU, then bake it out straight from the material editor, then use the baked jpg’s for GPU as a bitmap
