LG, too, recently launched the Optimus 2x (.pdf) pictured below, also equipped with a Tegra 2 processor, which the company highlighted at its Consumer Electronics press conference.

It’s interesting to see phone manufacturers bragging about processor cores in devices that are typically low-powered and running lightweight apps compared to the average computer.

This makes sense particularly for Android phones. Two cores enable a CPU to process two tasks simultaneously much faster than a single-core chip. Therefore, the Tegra 2 could take advantage of the Android OS’s beefy multitasking capabilities.

Each phone is flexing muscle in a different way, however. Motorola’s Atrix boasts compatibility with 4G, AT&T’s newest and supposedly fastest cellular network.

As for the Optimus 2x, LG is highlighting the smartphone’s ability to record and play 1080p video content.

Which phone is the more powerful? Here are the full specs of each handset for quick comparison:
