LG is diving head-first into the mobile processor market with an eight-core chip known as Nuclun (pronounced NOO-klun). Like the competition, the Korean tech giant's new chip is based on a design licensed from ARM.

Specifically, Nuclun uses ARM's big.LITTLE configuration like we've seen in Samsung Exynos chips. Under this configuration, four Cortex-A15 processing cores clocked at 1.5GHz are paired with four Cortex-A7 cores ticking along at 1.2GHz.

The A15 cores handle CPU-intensive tasks while the A7 cores are reserved for lighter loads to conserve battery life. The chip also supports 4G LTE-A Cat.6 with a maximum download speed of up to 225Mbps and is backwards compatible with current LTE networks.

Rumors regarding LG's in-house chip first surfaced back in April and fueled speculation that it might show up in the LG G3. As we now know, that turned out not to be the case.

Instead, the Nuclun will power the upcoming LG G3 Screen, a device packing a 5.9-inch display destined for the Korean market. There's no indication that this phone will be sold elsewhere and could simply serve as a test bed to see how the chip performs in the real world.

Considering it's just a variant of the LG G3 that's already on the market, I wouldn't expect LG to globally distribute it. I would, however, be curious to see how the new chip handles the high-resolution display as there was a noticeable performance hit in our review sample with the Snapdragon 801 SoC while gaming.

LG Mobile chief executive Jong-seok Park noted that with their new in-house solution, LG will be able to achieve better vertical integration and further diversify their product strategy when dealing with stronger competition.
