5 of the best quad-core gadgets

Huawei Ascend D Quad
Huawei's Ascend D was the first quad-core smartphone announced at the Mobile World Congress, which for a while earned it the world's fastest smartphone title. That is, until the HTC One X and LG 4X HD came along and ruined the party. Huawei's quad-core beast has shunned Nvidia's Tegra 3 chip in favour of its own stock – a 1.5GHz K3V2 chip, which boasts up to 30% energy savings. Processing power aside, the Ascend D squeezes in a 4.5in 720p screen, Dolby surround sound, an 8MP shooter with 1080p video recording and Android 4.0 Ice Cream Sandwich into an 8.9mm thin body.
