Over the past few weeks we’ve seen a few leaks regarding an upcoming smartphone from the folks at LG that is rather powerful. Blasting through benchmarks and sounding quite impressive. Then even more details leaked regarding the LG Optimus G smartphone. We now can confirm that Qualcomm‘s extremely fast and efficient new quad-core will be powering the device.

The current processor powering all the most popular smartphones is Qualcomm’s Snapdragon S4 1.5 GHz dual-core processor, that manages to hold its own rather well against current quad-cores. We got our first look at the new S4 Pro quad-core last month but we now know it is coming, and coming soon.

Qualcomm has confirmed they’ve partnered with LG and have been collaborating on releasing a powerful quad-core 4G LTE device they are calling a “global device.” This will support full 3G and 4G LTE with what they call 3G/LTE multi-mode. So the tradeoff between 3G and 4G LTE will be seamless — something we haven’t seen in the past.

Qualcomm will supply the latest Snapdragon™ S4 Pro platform to LG, enabling LG’s new quad-core smartphone, which is currently in production with anticipated commercial availability in Korea in September and global rollout to follow. This smartphone will be the newest commercial and global device to offer a quad core CPU Snapdragon S4 processor along with 3G/LTE multi-mode capabilities, delivering a superior mobile experience for voice, web browsing, games, user interfaces and other graphics applications.

Qualcomm calmly mentions an anticipated release date for September with a global rollout to follow. We’ve heard rumors of an LG Eclipse 4G LTE quad-core phone headed to AT&T in October, so this seems to confirm previous leaks. Either way we can expect some impressively powerful quad-core smartphones to blow the competition away in the next few months thanks to Qualcomm. Have a look below at some recent quad-core news and stay up to date.
