    Phoronix: More AMDGPU Linux Firmware Published For RDNA 3+

    Last month we began seeing AMDGPU driver firmware files published for the rumored "RDNA3+" hardware as an RDNA3 refresh (also as "RDNA 3.5") for upcoming APUs. More firmware files have now landed public in linux-firmware.git for these forthcoming RDNA3 refresh products...

    Is this the one having the newest video hw or RDNA4 or whatever? I'm confused by tons of terms for each core set and such.

        rdna "3.5" is rdna 4 because rdna 4 is a refresh of rdna 3. so that's why you see people calling it "3.5." they scraped original rdna 4 to focus most of their resources on "rdna 5" because rdna 5 is going to be a fresh design again. like how rdna was over gcn. but keeping the rdna branding instead of dropping the previous branding like they did with gcn to rdna. porting their original rdna architecture to chiplets was more challenging than they originally thought. they ran into to many issues with rdna 3 because of it. why rdna 5 is a complete redesign so they can build a new architure around chiplets in mind.
        at least, according to moores law is dead.
        so think of rdna 4 as what raptor lake was to alder lake. small tweaks here and there with their rdna 4 "flagship" being a 7900 xtx level of performance but at reduced power consumption (again, according to moore's law is dead). rdna 4 is not moving the performance meter for amd.

          So the video part is the same? How will RDNA 5 be then?

              RDNA 3.5 / RDNA 3+ is confirmed by AMD to be used in upcoming Strix APUs used in laptop and mini-pc along with Zen5 cpu cores (maybe also some desktop ryzen xxxxG processor later but we cannot know).

              RDNA 4 should be used, according to some unofficial news/leaks, in future PlayStation 5 Pro and Radeon RX 8xxx discrete GPUs. Not sure if any of this as been confirmed by AMD.

              With regard to Video Hardware Decode/encode the component is called VCN (Video Core Next). The version added with the that commit is 4.0.6, so same main version as all current RDNA3 product (my laptop phoenix 7x40u/hs APU uses VCN 4.0.2, rx 7900 may use 4.0.0 IIRC, rembrant 7x35/6x00u/hs apu uses rdna 2 and VCN 3.1.2 IIRC).
