Performance

Both tablets use MediaTek solutions, the Cube Talk 8 runs on a MediaTek MT8382 quad-core processor clocked at 1.3GHz, while the U27GT runs on a more powerful MT8127 quad-core chipset, also clocked at 1.3GHZ. The main difference between the two is GPU. The Talk 8 features Mali-400MP2, which is a little bit underwhelming compared to the Mali-450MP4 in the U27GT. Both tablets are equipped with 1GB of RAM to help with multi-tasking.

For everyday tasks, the specs are suitable for both tablets. Flicking through homescreens is smooth, web browsing is quick and applications launch with little issue. Only when the CPUs are pushed to their limits should you begin to see signs of a struggle.

Running the gaming benchmarks, the Talk 8 scores a 2351 in the Ice Storm Extreme test putting it behind the U27GT (2362). In the Ice Storm test it scores a 3121 placing it around the performance of the Galaxy Tab 3 8.0.

The Talk 8 musters up a 17,242 score in the AnTuTu benchmark, very much the same as the score notched by the U27GT (17,368).

The Geekbench 3.0 benchmark, meanwhile, gives the Talk 8 a score of 1176 and the U27GT a score of 1,090, both are pretty respectable.

Other Benchmark results and comparisons

Benchmark score is one thing of course and running "Asphalt 7" there's little signs of lag on both the U27GT and Talk 8.
The Talk 8 does struggle a little bit to run "Need for Speed 17", but the U27GT doesn't have the same problem.
Connectivity
Both the Talk 8 and the U27GT have Wi-Fi and Bluetooth 4.0 on board. The Talk 8 tablet is promoted more as a complete device, which has both phone and tablet qualities. Thankfully, the voice-calling feature on the Talk 8 lives up to the expectation. The call quality was good and the tablet was able to latch on to cellular networks even in weak signal areas which came in handy at times. Besides, the Talk 8 also has some other useful features such as GPS and FM Radio, making it more of a phone than a tablet. Both models come in 8GB, with a Micro SD card slot available to expand the storage.
