    Phoronix: RadeonSI Gallium3D Gets Wired For Compute-Only Arcturus To Handle Video Decode

    In addition to new patches coming out on Monday for addressing power management with AMD's unreleased "Arcturus" GPU, a set of Mesa patches were merged for adding RadeonSI Gallium3D driver support...

    Any information about VCN 2.5?

      tildearrow newer hw doesn't use VCE it's succeeded by VCN.

        I wonder if Arcturus also has the 3D engine on the chip and if it is a customized and updated Vega 10/20 under the hood and could be used as such.

          I fixed it to VCN.

            are you stupid? we requested a compute only chip without any "3D Engine" for tasks like Blockchain mining years ago.

            Now we get it and you do speculation about a magic 3D Engine on top of a compute only chip.

            I remember the forum posts with Bridgman years ago he pointed out that many compute-only customers really do use the video VCN unit. this means the babbling here in the phoronx.com forum is more productive for future planing of new products than many people believe.

            One if for sure if the next blockchain mining boom comes up Nvidia will be doomed because of the "Arcturus" chips.

            I think the chip without "3D Engine" can save 40% of the silicium chip die. so the price will be very competitive for people who do compute only stuff.

              I am just curious, not stupid. A compute-only chip would be a new thing though as they would need to re-architect the whole chip for this purpose.

              And while I see a purpose for such a compute-only card, it must be competitive with much more flexible fully-functional GPUs from the competition and other specialized AI-hardware which should have a performance/watt advantage. Thus it could serve a market right in the middle (as for being usable for a wider range of compute tasks).

              But I was originally wondering if we see an updated Vega 10/20 chip for HPC after all.

                it has 8192 shader cores and if you read articles about other 7nm GPUs it will have up to 2GHZ.
                and 64GB of HBM2 ram.

                because it has no 3D-graphik it saves ~40% of the die chip means they can sell it with a very competitive price.

                "they would need to re-architect the whole chip for this purpose."

                this is cheaper for amd than you think. the last cpu who was designed by hand was the Phenom II X6 1090T... after that like the FX8350 they used automated tools for the design.

                with this automated tools is is very easy to re-architect a chip for compute only purpose.

                and be sure they asked some customers about "compute-only" hardware at a very competitive price and for sure many server or mining customers said to them yes do it.
