Chinese manufacturer Huawei intends to stake its high-end claim at Mobile World Congress 2012, and they're off to a good start. The previously indicated Diamond line of devices will begin with the Ascend D Quad, featuring Huawei's very own ARM-based quad-core processor, the K3V2. We had expected them to rely on Nvidia's Tegra 3 architecture, but it looks like they're keeping it in the family. The company claims that this bit of 1.5ghz silicon helps it perform 49% faster than conventional devices (making it the "world's fastest smartphone") while improving battery life. Other major specifications include a 4.5-inch 720p touchscreen and Ice Cream Sandwich.
