Today’s match includes two phones that were announced at the Mobile World Congress 2012 in Barcelona a few weeks ago. LG had announced the LG Optimus 4X HD, the successor to the LG Optimus 2X from last year. Meanwhile, HTC also revealed its HTC One X. Naturally, we can’t resist seeing how these potential giants measure up to each other in the ring.

Design and Display

The LG Optimus 4X HD is rocking a 4.7 inch True HD IPS display with 1280×720 pixel resolution. LG is promising the “finest viewing experience with high resolution, clarity and no color or shape distortion.”

Despite the size of its display, the LG Optimus 4X HD is surprisingly super slim at 8.9 mm in thickness. We don’t have additional details on the phone’s dimensions as of this writing, but we’re told that the LG Optimus 4X HD fits comfortably in the hand.

Similarly, the HTC One X boasts a similar 1280×720 pixel resolution with its own Super IPS LCD2 capacitive touchscreen. Its display is also the same size as LG’s phone, at 4.7 inches. The phone has dimensions of 134.4 x 69.9 x 8.9 mm, which means that it will be just as super slim as the LG Optimus 4X HD. Unfortunately, however, it may not actually feel as comfortable in the hand and may just be a little too big for smaller hands. It weighs about 130 grams.


The LG Optimus 4X HD has an internal memory of 16 GB and 1 GB of DDR2 RAM. For those of you who want additional space, the LG Optimus 4X HD has a microSD card slot and allows you to expand memory up to 32 GB.

The HTC One X on the other hand is packing more internal memory at 32 GB. Unfortunately, it seems that the HTC One X doesn’t have a card slot and cannot be expandable. That may discourage users who would like to carry a lot of files with them. The HTC One X also packs 1 GB RAM.


Both phones appear to be evenly matched as they are both equipped with an 8-megapixel camera and a front-facing, 1.3-megapixel camera.

Processor and Operating System

The LG Optimus 4X HD is equipped with Nvidia’s powerful 1.5 GHz quad-core Tegra 3 processor with 4-Plus-1 technology. Out of the box, it’s powered by Android 4.0 Ice Cream Sandwich.

Sources say that the LG Optimus 4X HD also have a fifth “companion core for less intensive tasks such as standby mode and music playback.” The idea is to keep all of the power of the four main cores until when it’s actually needed. It has a GeForce GPU.

Not to be beaten, the HTC One X also packs a 1.5 GHz quad-core chipset with four high-performance CPU cores. Just like the LG Optimus 4X HD, it runs on Android 4.0 Ice Cream Sandwich out of the box. It wouldn’t be an HTC phone without HTC Sense 4.0, which has been “streamlined”, in HTC’s words.

HTC Sense 4.0 appears to be lightweight and nippy, with minimal transitions and elegant 3D effects. Even HTC has picked up on the Nvidia Tegra 3 processor and the GeForce GPU.


The LG Optimus 4X HD is equipped with a 2100 mAh battery while the HTC One X, by comparison, is packing a less powerful 1800 mAh. As of this writing, there have been no real battery tests on either of these phones so we don’t know yet for sure how long these phones will last on standby mode and after continuous calls.


These phones appear evenly matched in terms of the gear they pack inside as well as their gorgeous displays. The one thing that truly sets them apart, however, is the HTC One X’s lack of a card slot which means that you’ve got to make do with the 32 GB internal memory it comes with. Until these phones reach consumers’ hands, we can only guess which of them will emerge victorious.

The era of quad-core Android phones has come.  Which of these two quad-cores is making your eyes twinkle?
