    I am unaware of any previous mating of x86 and Mali. So maybe not so much "from scratch" but "unproven" would be more accurate.

    I meant the MX4Pro, didn't have the chance to test out the MX4 yet.
    Again, it's just a case of recompiling the drivers. All graphics driver's I've seen till now are written in a extremely platform and OS agnostic way. The porting effort would be minimal.

    Wow, it went completely under my radar that Intel was licensing its CPU to a SoC maker.
    I agree the driver would be pretty agnostic, even with identical CPU cores SoCs are all different from each other and you have ARMv7 vs ARMv8, sometimes MIPS.

    I suppose there could be endianness issues, I don't know if ARM SoCs use big endian or little endian, Atom definitely uses litttle endian.

    I wonder is the Sofia project limited to non windows platforms ? If not then there are no dx drivers for Mali on any platform

    I didn't even think about that Sofia platform and Windows, only about Android and Linux (can be fine for Firefox OS or Chrome OS too)

    Mali 450 has outdated features : OpenGL ES 2.0 but not 3.0, more modern ones claim OpenGL 3.0 and DirectX 11 (which I take to mean the chip can support DX11, but there might be no available driver and whole computer system (tablet, phone etc.) that runs Windows on a Mali (yet)

    Depends what one would want to do with DX11; for tessellation they don't have any dedicated logic.It's all going through compute afaik.

    The Pro has the Exynos 5430 or not?

    Can someone compare gpus in 6732 and qualcomm 615?
    T760-mp2 vs adreno 405.
    On paper it seems adreno 405 is faster, tho first benchmark results for 760-mp2 (mtk6732) show higher antutu results (40000+ for antutu 5.6)

    If you know any devices carrying each GPU you could search for them in the Gfxbench3.0 database for results. No idea if the link will work: http://gfxbench.com/result.jsp?benchmark=gfx30&test=545&order=score&base=gpu&ff-check-desktop=0

    Since when is antutu a reliable benchmark for anything?

    The problem is - I can't find any other becnhmark/test which has results for these...
    http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html - doesn't have any Adreno 4xx scores :/
    Best I found http://wccftech.com/galaxy-note-4-snapdragon-vs-exynos/ shows that 420 is faster than 760-mp16, but still can't find reliable results with 610/615 chipset :/


    PS:
    Big thanks!
    It seems in the bneginning I misused notebookcheck site :)
    After some digging I do found good comparison between 6732 and 615:
    http://gfxbench.com/device.jsp?benchmark=gfx30&os=Android&api=gl&D=Meizu m1 note (6732)
    http://gfxbench.com/device.jsp?benchmark=gfx30&os=Android&api=gl&D=Coolpad 8675-W00 (Adreno 405) (615)

    Isn't the comparison a little bit wrong?

    IMHO the MT6732 is more comparable with the Qualcomm 410

    A IMHO better comparison would be between the Qualcomm 615 and the MT 6752

    Well, so far I have no idea what are differencies between gpu in 6752 and 6732 ... maybe frequencies...maybe not
    But I saw claims that 6732 is more powerful than 615 so I started looking for data

    indeed, according to notebookcheck the difference is only the frequency. max. 700MHz for the MT6752 and max. 500MHz for the MT6732. So only up to 40% difference in performance

    I was surprised myself that the MT6732 has such a high performance. I expected a performance a little lower than for the Qualcomm 410 (MHz for MHz) but not a performance higher than the 615.

    well, it is not faster, but is in same league.
    And +40% for 6752 is not bad at all. Too bad both have only single channel memory path - this will limit the speed in RL games

    Anything that then involves traversing O(n^2) vertices of the Ikea space-filling-curve is not free IMHO.

    Still waiting on that Nexus 9 and Exynos 5430/5433 analysis too ;)
    The Exynos 5433 in the Note 4 has a 760-mp6 not mp16. I dont know what the 7420 has but I think it should be at least an MP8. That should be an interesting comparison to Adreno 430.
    Mediatek has really caught up to Qualcomm in the mid-range market and is giving it a lot of competition now. That said..I think S410 was intentionally targeted towards cheaper cost and quicker time to market than performance. (And I also believe that Qualcomm tends to have lower power consumption than Mediatek for the same class of chips). S610 and S615 are the real competition to 6732 and 6752.

    PS: Slightly off-topic but I'm curious about this. Are S610 and S615 two different chips or just the same silicon with cores disabled. Same question for MT6732 and 6752. Anyone know?

    Hopefully both will be out next few days... (Actually all 3 articles, depending on scheduling)

    OT: My wife literally forgets to charge her THL4000.

    Someone drew my attention to this baby in the meantime:

    Nice design and another excellent price/performance ratio.
