HTC One X has hogged the limelight ever since its grand unveiling at the Mobile World Congress (MWC) 2012 held in Barcelona. One X is undoubtedly the flagship smartphone from HTC, power-packed with great features and focused at delivering sublime performance.

Both Samsung's Galaxy S3 and iPhone 5 are under threat from the leading Android smartphone - One X - that promises to subdue all competition in the market. But the S3 and iPhone 5 are no pushovers and make for an exciting battle ahead.

The quad-core battle has just begun stealing the spotlight away from dual-core smartphones including the iPhone 5. That's another reason for Apple to be worried. Despite delivering on most counts, Apple seems to have missed a trick or two.

Let's take a look at the feature comparison between the two leading Android smartphones.

Display: HTC One X sports a 4.7-inch (720 X 1280 pixels) Super IPS LCD2 capacitive touchscreen display with 312ppi (pixels per inch) pixel density and scratch-resistant Gorilla Glass empowerment.

In contrast, the Galaxy S3 features a 4.8-inch Super AMOLED Plus 720p HD display (720 x 1280 pixels) with 319ppi pixel density and also includes the Corning Gorilla Glass for protection against scratches.

Verdict: One X is the clear winner with a superior IPS LCD2 display technology that promises better picture clarity than the AMOLED counterpart.

Dimensions: One X weighs 130g and is 134.36mm tall, 69.9mm wide and 8.9mm thick. In comparison, the S3 is also expected to be 8.9mm thick and weigh 135g.

Verdict: There is no clear winner in this category, as both come with similar specifications.

Memory: The HTC smartphone ports 1GB of RAM and 32GB of internal memory sans support for microSD slot.

On the other hand, Samsung's S3 includes 2GB of RAM and 16GB/32GB storage capability with support for microSD slot expandable up to 32GB.

Verdict: With support for microSD slot and larger system memory (RAM), the Galaxy S3 is the clear winner in the memory department.

Operating System: BothOne X and Galaxy S3 will run on the exciting Ice Cream Sandwich (Android 4.0) platform. The former harbours the Sense 4.0 UI onboard, while the latter will port the TouchWiz 3.0 or better.

Verdict: HTC's Sense UI will provide slick and seamless font/image rendering quality particularly with web browsing, while the TouchWiz UI provides zippy and smooth user experience. There is no clear winner in this category and it is a draw.

Processor: HTC's flagship smartphone boasts a powerful 1.5 GHz Nvidia Tegra 3 quad-core processor onboard. Meanwhile, there is good news for the US consumers, as the US version running on AT&T will sport a superior 1.5 GHz Qualcomm S4 dual-core chip. That should truly complement the speed of 4G LTE services offered by AT&T.

In contrast, the S3 is expected to ship with a 1.8GHz quad-core processor based on the Exynos 4212/Exyos 5250 chipset.

Verdict: Expect a closely contested battle in the quad-core department. As there seems to be no clear winner, we call it a draw.

Connectivity and Network: One X will support LTE connectivity over AT&T's HSPA+ 4G network across 850/900/1900 and 2100MHz network bands. The connectivity option also includes Wi-Fi 802.11 a/b/g/n, besides supporting Wi-Fi hotspot and Bluetooth v4.0 with A2DP.

On the other hand, the S3 also supports similar Wi-Fi capabilities alongside Bluetooth connectivity. The 4G LTE support includes LTE 700 network band, alongside 3G bands HSDPA 850/900/1900 and 2100 MHz bands.

Verdict: There is no winner in this category, as both the smartphones support 3G and 4G networks.

Camera: The S3 is expected to boast a powerful 12 megapixel (4000x3000 pixels) rear camera with autofocus and LED Flash that will blow away all competition from the rival camp. The camera ports advanced features such as Geo-tagging, touch focus, face and smile detection, besides image stabilization. Its rear camera also adds support for 1080p video recording at 30fps (frames per second). It also flaunts a 2MP front camera for video chatting as opposed to 1.3MP front camera on the HTC One X.

In comparison, the One X offers a less powerful 8MP rear camera (3264x2448 pixels) with autofocus and LED flash. The phone facilitates simultaneous HD video recording (1080p at 30fps) and image recording (720p). The camera also supports geo-tagging, face and smile detection.

Verdict: Boasting a powerful 12MP rear camera and a decent 2MP front camera, the S3 undoubtedly wins the camera contest hands down.

Battery: One X features an 1800mAh Li-Po battery, while the S3 is expected to flaunt a larger and more powerful 2250mAh battery for a longer battery-life.

Verdict: The Galaxy S3 is the clear winner in this category with a larger battery.

Overall, both the smartphones impress with power-packed configuration. The S3 however, holds the edge with impressive sales records held by its predecessors and marginally better specifications to boot. It is still a hard question to answer who will be the clear winner in terms of performance. You might leave your comments on who you think would be the winner, as we await the release of another flagship smartphone from the Korean giant.
