    So far the progress you're talking about exists on powerpoint slides only.
    Heh, I was waiting for you to show up, in this thread. Still not ready to disclose your conflict of interest?

      That's really not a GPU, or even something that's designed to be fabbed. Anyone wanting to use it would have to do all the layout, themselves. When you buy IP from SiFive, they will already have done the work needed to fab it on several popular nodes.

        PowerVR works with risc-v chips...
        Thank you, I completely missed out several mobile-grade GPU platforms already work with risc-v. Seems like things are finally coming together.

        Like the PowerVR support you already mentioned. It seems Imagination also wants to make their own risc-v based SOCs as well.

        Apparently, Alibaba has a SOC that pairs a Vivante GPU with risc-v cores.

          While the BeagleV was never shipped, the BeagleBoard foundation boards are where Risc-V for tinkerers is expected to be happening, at least for now (a revised BeagleBoard RiscV board is expected to be announced in early 2022).
