My new tablet

Note: This was originally posted on 29th May 2012 at http://forums.arm.com

Hi,
I have just bought a new (very cheap) tablet and am confused about the processor.
It is a Synaptics 7" MID and the processor was specified as being A10 1500MHz.
The box has no identification on it at all. No make, name or model.
When I look at 'about tablet' the info is very sketchy and says only model MID then android and kernel version.
I have installed the Quadrant app, and the processor spec says this:-
ARMv7 Processor rev2 (v71)
current  freq 1008MHz
max freq 1008
min freq 60MHz
Cores 1
Architecture 7
BogoMIPS 1001.88
Hardware sun4i
Revision 2
Serial # 0000000000000000

The tablet runs reasonably well, but on such as google maps or street view, it is incredibly slow.
Could anyone tell me if this is as specified please?

Many thanks
frostyboy

    Hi and welcome frostyboy,

    The A10 is most likely from Allwinner, based on the ARM Cortex-A8 processor and Mali-400 GPU (Wiki says!)
    Here is Allwinner Technology official product page, in Chinese...
    Your test says the chip was running at 1GHz during the test, but that doesn't mean it cannot achieve the advertised 1.5GHz.

    This System on Chip (SoC) is powerful enough to handle Google Maps properly. I have a less powerful phone which does.

    Cheers,
    Alban

    Hi,
    Thanks for your reply Alban.
    It seems from what you say that this could be an A10 then.
    Other tablets I've seen advertised were A8 and more expensive, so I assumed this would be the bees knees.
    The Quadrant readout did say Max: 1008MHz though.

    Some web browsing suggests to me that the Allwinner A10 would indeed be a 1-1.1GHz part but that it could be overclocked.
    This could explain the mention you see on the box.

    About the A-something, there could be some confusion. Allwinner doesn't seem to do anything called "A8".
    The "A8" you are referring to could be a ARM Cortex-A8 CPU though... but the Allwinner A10 is also based on ARM Cortex-A8 processor. There isn't any ARM Cortex-A10.
    Confusing I agree, that's why I don't shorten the "ARM Cortex-A8" :)

    Hi,
    A further development.
    I visited the original purchase website to remind myself of the actual specification listed.
    Here is a pasted copy:-

    Operating System: Android 4.0

    Processor Chip: A10 Multicore 1.5Ghz

    Keyboard: Android Touchscreen (optional usb leather case with keyboard)

    Screen Technology: 5-Point capacitive touchscreen (Pinch/Zoom Feature)

    Screen Size: 7 inch (Diagonal)

    Resolution: 800 x 480

    CPU Type: Cortex-A10

    CPU Speed: Max 1.5 GHz



    See now where my confusion comes from.

    A10, Cortex, Multicore and 1.5GHz are all mentioned.

    That does not seem to correspond to the Quadrant readout!

    Well... I can tell you for sure that ARM has not created any Cortex-A10.
    Then, there might be a bit of loose use of the term "processor". In tablets, you would rarely find a processor as such, but a System on Chip (SoC). A SoC would include a processor but not only that; the full system with controllers, graphic processor (GPU)... It's still a chip containing processors.
    Allwinner A10 SoC has several "cores" in the sense that it features an ARM Cortex-A8 CPU and an ARM Mali-400 GPU, it has a single "CPU core" though.

    The only difference I could see with your Quadrant result would be the clock speed. However, I don't know how Quadrant came up with that value.
    As you can find other manufacturers mentioning 1.5GHz from that SoC, I would tend to think it is possible, however I cannot confirm for your chip/device.

    Great help and advise thank you Alban.
    Just the sort of sense I needed.
