5 of the best quad-core gadgets
LG Optimus 4X HD
LG enters the quad-core race with its flagship Ice Cream Sandwich flavoured 4X HD smartphone. Running at 1.5GHz per core and packing a 4.7in 720p hi-def screen and NFC capabilities, LG's almighty blower packs an impressive punch. Chuck in an 8MP camera round the back and a 1.3MP front-facing shooter, a generous 2,150mAh battery, 1GB of RAM and 16GB of built-in storage, in an 8.9mm profile and you're looking at a pretty impressive spec sheet.
