There is no shortage of budget 3G tablets in the market. Products from brands as well-known as Lenovo and ASUS are now considerately priced. And second-tier Chinese manufacturers are also competing for a slice of the action by making even cheaper slates. The Cube Talk series is arguably the best-selling line of budget 3G tablets in China.
As the upgraded version of the once popular Talk 7X, Talk 7X Enhanced and the Talk 7X Quad-core, the Talk 7X Octa-core (U51GT C8) is powered by the much mightier MediaTek MT8392 octa-core processor, but the rest of the specs remain somewhat the same, so as the price tag of RMB499 ($82).

Design and Build
The Talk 7X Octa-core has inherited the design language of its predecessor. The front of the device houses a 7-inch display surrounded by a black bezel. Following the wonderful tradition of this Chinese manufacturer, the front panel of the 7X Octa-core does not include any branding. Also, thanks to the Kitkat's onscreen navigation keys, the front is devoid of physical buttons, leaving simply the black bezel with an earpiece, a VGA camera, a light sensor and a proximity sensor.
On the right side of the device are the rather excellent buttons, with the one piece volume rocker sited just below the power button. They have a very responsive feel and are easy to find with your fingertips. The buttons are colored white to match the finish of the rear side, blending in nicely.
Like its quad-core predecessor, the Talk 7X Octa-core has its micro-USB port located on the top of the device next to the standard 3.5mm headphone jack. While it's uncommon to find the USB port on the top of a tablet of this size, it is ergonomically sound as the Talk 7X Octa-core is simple to use while charging.
As we once mentioned in the review of the Talk 7X Quad-core, the positioning of this port also helps reduce the costs of manufacturing the tablet, as the circuit board has the connection for the port at the top. Cube has avoided running a cable to the bottom of the tablet as it had to on the original Talk 7 (Dual-core version).
The 2MP rear camera is housed in the upper left corner of the white glossy plastic back, which gives the tablet a somewhat cheap feeling.
The upper part of the rear side is removable, underneath are the dual SIM slot and Micro SD card slot. The only speaker gate is located at the bottom of the rear side, along with the Cube Logo and some other printings.
Measuring at 191*111*10.5mm, it has a smaller footprint than most of the 7-inch voice calling tablets on the market. But it is not slim by modern standards, the Cube Talk 9X is significantly thinner at only 7mm.
Every year that goes by, Chinese manufacturers make progress on the screens of their tablets. The Cube Talk 7X sports a 7-inch PLS panel, a derivative of the IPS technology found on the great majority of today's tablets.
The display of the Talk 7X has an average contrast ratio of 1100:1, which is pretty impressive when compared to the ordinary IPS panels found on most of the budget tablets.
The average screen brightness is 330cd/m², high enough to make this slate easy to look at outdoors. The resolution is a disappointment, though, as it is stays at the WSVGA standard (1024*600) seen on the Galaxy Tab P1000 from many years ago. And its cheaper RMB399 ($65) competition - the Colorfly E708 3G Pro tablet now has an IPS display at 1280*800.
