      VP9 decode? This is pretty much Vega only right? And even there it's very problematic: https://forum.doom9.org/showthread.p...71219&page=112

        The link you posted refers to Raven Ridge and VP9 10 bit, 8 bit (YT SDR) should be less problematic. Poor 10 bit performance might also be related to unfinished drivers. Situation in Chrome with D3D11VA would be interesting.
        Raven Ridge is more advanced than Vega discrete cards in terms of video decoding and display controller.

            Doesn't Raven Ridge counts as Vega? I thought so all the time.

              Depends what you consider "vega". Every GPU is a combination of IP blocks (display, memory controller, gfx/compute, multi-media, etc.). Raven shares a number of IP blocks with vega10 (e.g., gfx/compute), but some are different (display, multi-media).

                Depends, for Raven if you listen marketing you will hear Vega 3, 6, 8, 10 Graphics

                https://www.amd.com/en/products/ryzen-processors-laptop

                Now in drivers land you will hear some more exclusive and proper names than what marketing do... just do not think that for example "Graphics Model: Radeon™ RX Vega 10 Graphics" is the same thing as what vega10 Alex mentioned here

                Marketing just put Vega on anything which is this gen hardware, to put it simply Now if you like complication instead, you are at the right place

                Basically we are living in Vega era and that is there until Navi era begins... but of course we don't talk nor ask about future product nor names of eras

                Catalyst era, Crimson era, ReLive era, Adrenalin era... it seems every year we have some different dragon, eras where minners got most of the cards

                God bless Raven APUs, so we could buy something new Before that were Cats and now it is a Bird in that area, i guess next will be dog or snake and next-next again something in the sky or some planets as seems islands are obsolete

                  Tonga didn't see a new firmware file, does that mean it doesn't have this feature?

                    Just read TONGA column:

                    https://www.x.org/wiki/RadeonFeature/#index8h2

                    UVD 5.0 have neither HEVC decode nor encode capability.

                    Every chip (what is called here IP block) require new blobby for linux-libre to deblobby Because that software is not software, that is hardware as Bridgman like to say, even when it is not really hardware but sandware, it is hardware just to differinate it from software but it is really sandware...

                    Same obvious thing, just different vocabularium
