Samsung launched the successor to its Galaxy S3 smartphone, the Galaxy S4, on March 14. The burning question is whether the Samsung smartphone can surpass the milestones set by the device's predecessors and be yet another feather in the Korean company's cap.

HTC took the wraps off its HTC One flagship earlier in February 2013. The upcoming smartphone is touted as the next big thing and will give stiff competition to the likes of Samsung, Sony and Apple.

Here's how the Galaxy S4 and HTC One flagship phones measure up against each other.

The Galaxy S4 will house the much-touted 1.6GHz Exynos octa-core CPU (international versions) or a 1.9GHz quad-core Qualcomm Snapdragon 600 (U.S. version). The HTC One also packs in a quad-core Qualcomm Snapdragon 600 processor; however, this is clocked at 1.7GHz making the Samsung offering more powerful.

Display

The HTC One sports a 4.7-inch Super LCD 3 display with 1080 x 1920 pixels resolution. The Galaxy S4 has a slightly bigger 4.99-inch Super AMOLED display with the same pixels resolution.
