Huawei has debuted a monster of a smartphone here at Mobile World Congress, the 1.5-Ghz quad-core powered, 4.5-inch Ascend D quad. Huawei calls the processor its K3V2 and, in addition to sporting four CPU cores, it packs 16 GPU cores, giving it that extra oomph needed to handle today’s 3D games. Even more impressive is that the K3V2 is a 64-bit processor, rather than the standard 32-bit offered in other phones.

Beyond its processor, the Android 4.0 ice Cream Sandwich-powered Ascend D quad features a 4.5-inch 1280 x 720 display, Dolby Digital + 5.1 surround sound, 1GB of RAM and 8GB of onboard storage. We spent some hands-on time with the Ascend D quad and can certainly attest to its speed. Swiping through menus was fast and fluid without a hint of lag. In our hands the 0.35-inch thick Ascend D quad felt solid. It has a thin rubberized texture on the back that helps make it feel more secure while holding.

Giving the Ascend D quad life is an 1800mAh battery that, combined with low-power consumption technology, Huawei says will last for one to two days of regular use. In fact, Huawei claims its battery technology gives the Ascend D quad up to 30 percent better battery life than the competition. Better still, Huawei is also offering an Ascend D quad XL with a 2500mAh will last for two to three days of regular use.

The Ascend D quad measures 0.35 inches thick, while the XL model is .04 inches thick and weighs in at 4.6 ounces. Huawei says the difference in weight between the two models will be less than roughly .7 ounces, so expect the Ascend D quad to weigh in at around 3.9 ounces.

Huawei says the device will be available  globally, including North America, in Q2 2012 as an HSPA+ model. A 4G LTE model is expected to follow towards the end of Summer 2012.
