Above is the basic specification, we can see there is no Bluetooth or GPS, 3G built in this device, it is a little pity.

We have run a Antutu Test, score is about 12000, and we also do a screen test for this 10 inch IPS screen, it has good view angel.
Here is some details about the test.
Antutu benchmark result


System info


As you can see from the System Info that this tablet equipped with a quad core CPU, as it is a engineering prototype, the CPU frequency is locked to 1008.0MHz and the model is still its engneering code name sun6i. Fortunately, the Antutu recognizes its GPU is PowerVR SGX544MP. This is a powerful GPU that uses in Apple's A6X processor and TI's OMAP4470 processor. So it has the same graphics performance as iPad 4.

NenaMark 2 test result



From the result we can see that the GPU performance beyond most well-known devices. And it's definitely better than Mali-400MP4 that uses in Samsung's quad core tablets.

Can you ask the factory why the CPU isn't running at full speed.

It seems as if the Allwinner is locked to 1ghz when it should be able to do 1.2ghz.

For the stability concern, the frequency was locked to 1GHz, but some users had crack it and overclock the GPU to maximum 1.5GHz.
