    Change of mind? ;-)

    That's why Warp3D Nova has started supporting Polaris/GCN4 seven months ago:

    Make that 4 instead of 2. OS4 jumped straight to GCN4 from GCN1, skipping GCN2 and GCN3.

    Just now I overclocked my Pegasos 2 to 1.33GHz and want also upgraded graphics. I take Radeon 9800Pro and will try overclocking. But maybe HD4xxx will be better choice.



    That is an accomplishment, but I think I would have just looked for a universally keyed R360 based card. At least you'd have 3D support. Although with the R700, you do still get overlay support. I don't play a lot of games, so 3D is less important.


    Yes. I was try to find universal-keyed R360.
    But - the best R360 card I found is probably 9800 XT (cca 8% faster then my 9800PRO), only 1.5V version.
    The only universal AGP with R360 what I found was ATI FireGL X2-256 - and this have different RAM config, i.e. it cannot be flashed to 9800XT. The best solution seems to be slightly overclock my 9800PRO.

    Because I need more compositing and prefer actual Morphos SDL games over 3D games, I was asking for benchmarks. Doesn't matter, if I get some HD4xxx, I test it and post benchmarks here.

    I rather liked GCN1 myself.
    GCN2, since my only experience with that was an R7 260X, was a bit of a disappointment.

    I believe Mark has a representatives of GCN 1, 2, 3, and 4.

    I'd just like to be able to use a Radeon 7770.

    Although...an RX580 would be nice. ;-)
    I believe Mark mentioned owning an RX570, so GCN4 support is not an impossibility.

    Addendum: As Navi is apparently GCN derived, that would make it GCN5 wouldn't it (as Radeon VII appears to just be GCN4 on steriods).

    We haven't even ventured into GCN support, and the last GCN generation is due to be launched this year.

    Modern video card support, improved OpenGL support, SMP, and memory protection.
    All of which could be started on our higher end PPC systems, but are a must for an X64 variant.

    Look no further. Seems there has been made such a thing for the Xserve G4.

    Well, on PPC it's not that easy... If you have a look at Linux drivers you will realize Polaris & Navi only run on Little Endian mode if at all. And I think for Navi you still need out-of-tree kernel patches to get them going at all. Also they are far from stable.

    But even on the x86_64 side Navi has lots of issues still, which you can have a look at the mesa bugtracker. Current GPU's are a quickly moving target in terms of driver support... Even for Polaris cards features still are being tested/enabled in the Linux kernel and this generation is basically 4 years old.

    IMHO 'sweet spot' still would be the Radeon HD2400 - HD7670 cards (r600 up to Northern Islands) which have good support on x86_64 and on PPC (LE or BE) rarely have issues.

    Unlike those wannabe coders on Linux, the mighty MorphOS developers surely have the skills (and will) to write endian-agnostic drivers :-) Also, they can write stable code, and Linux kernel patches are irrelevant for MorphOS ;-)

    Already supported in MorphOS in 2D (except HD6930 to HD6990 based on Terascale 3), even overlay for R700 and below.

    True. How could I miss that? :-D

    Also true. 3D support is the key here.
