We've seen a raft of quad-core phones launch during MWC 2012 and so it's time to pitch them against one another in a titanic QUAD BATTLE.
Don't think you'll be able to get these handsets on lower tariffs though - they are all high-end phones that will be available for a real premium when they launch. Which has the best specs? Read on to find out.
HTC One X vs LG Optimus 4X HD vs Huawei Ascend D Quad vs ZTE Era: Processor
Naturally, all the phones are quad-core; that's what this is all about, right? The HTC One X, ZTE Era and LG Optimus 4X HD have Nvidia Tegra 3 processors (featuring that secret fifth core). The One X and 4X HD have Tegras clocked at 1.5GHz but the ZTE Era is clocked at a barely-noticeable 0.2GHz slower. The Huawei Ascend D Quad is the handset that sticks out on a limb, with its own Huawei K3V2 chipset featuring a 1.5GHz quad-core processor.
HTC One X vs LG Optimus 4X HD vs Huawei Ascend D Quad vs ZTE Era: Design
All these phones are rather fine-looking - the One X features a Unibody design formed from rather cool polycarbonate (super-lightweight with the ruggedness of metal, according to HTC). In our hands on we also approved of the LG's design. "Approach the LG Optimus 4X HD and you do feel that you are looking at a premium phone with the dual metal rims running around the circumference, sandwiching prism detailing which is part of LG's new signature design." The Ascend D and ZTE Era are also no slouches in the area of design, although we weren't too impressed by the plasticky sections on the back of the ZTE.
Here are the four handsets in pictures:

HTC One X vs LG Optimus 4X HD vs Huawei Ascend D Quad vs ZTE Era: Screen
The One X and Optimus 4X are strikingly similar – both have a 4.7-inch, IPS (no OLED) 720p HD screen (720 x 1,280 resolution) boasting a pixel density around the 312ppi mark. This compared to the iPhone 4S which clocks in around 329ppi. The Huawei Ascend D Quad offers a near-4S density of 236ppi because of its smaller 4.5-inch screen; it's still 720p HD. The ZTE Era is the poor relation here, with a 4.3-inch, 540 x 960 pixel display.
