    Wouldn't that pedantically be neither a CPU nor a GPU anymore but something altogether different? But yeah, probably would have to be a separate hardware driver to utilize those functionalities that go over what a CPU has.

      I guess the upcoming Larrabee GPU follows this direction he describes.
      But how does Gallium3D fit into the picture? Does Gallium3D have a place in pure software rendering?
      IMO, I think GPU's will be merged with the CPU, making a new type of CPU that can handle huge amounts of streams simultaneously like the GPU's today. (Basically moving the GPU to the CPU die)

        What would be awesome is if the likes of NVidia and ATI would license the arm core and build a CPU with an integrated graphics pipeline and DDR3 memory controller.

          Tegra?

          You mean like NVIDIA's Tegra platform?...

            /me goes to investigate!

            EDIT: Wow, yes.. that is exactly what I meant. Cool! Next, we need unix graphics workstations based on that. :P

              ARM workstations? They just don't have the oomph. AMD's Fusion and Intel's Arrendale would be better there, with AMD parts being better for graphic-intensive use as always.

                There is still no hardware-accelerated Gallium3D. How long do you think it will take to make Gallium3D usable as a driver infrastructure? 3 years, I guess?

                  partial implementations for Intel's 915/965 IGP, ATI R300 and the Nouveau project for Nvidia cards. I think the Intel one is usable, but not for mainstream, the others are in an early development stage.

                    On ATi card side they probably want the existing driver infra (classic Mesa with radeon-rewrite, KMS+ttm) to be stable before focus moves on Gallium3D. They just stop extending it beyond a certain point. (which has not yet been definitely decided) It's easier to test the KMS+ttm against a Mesa implementation whose core doesn't change every time you look the other direction, ya know? After that part is done, we should look forward to getting Gallium3D drivers at a nice pace...

                      Now it makes sense to me. Thanks for the explanation.
