Compared to the Zopo Z999 carrying the same SoC the "good deal" is highly relative; the MX4 might have a small edge for the sw against the fore mentioned Zopo but nothing immediately noticable to even remotely justify the price difference. Plus I have the impression from the quick looks I had that the Zopo has a better display.

I meant the MX4Pro, didn't have the chance to test out the MX4 yet.

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

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Mali 450 has outdated features : OpenGL ES 2.0 but not 3.0, more modern ones claim OpenGL 3.0 and DirectX 11 (which I take to mean the chip can support DX11, but there might be no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)
http://fr.wikipedia.org/wiki/ARM_Mali#Mod.C3.A8les
 
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.
 
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

I don't find the software to be bad at all, just the Chinese store / theme engine seemed not finished for the western market. Otherwise it is an extremely solid phone and beats out the Huawei offerings by quite a bit. Hope to have the review up within a week.

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?

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.
