A beefed up LG G3 has showed up in Korea with Category 6 Advanced LTE speeds and may launch as the much-rumored LG G3 Prime variant.

The LG G3 is already a powerhouse on its own, boasting a stunning display and top-notch specs and features that make it one of the best devices currently available on the market. Nevertheless, the rumor mill kept churning in anticipation of an even higher-end version, dubbed the LG G3 Prime, and it now seems those rumors were true.

While the U.S. is just getting the original LG G3 in stores, Korea already has a more powerful version of the handset, promising blazing-fast LTE speeds. More specifically, a new version of the LG G3 is touted in a Korean mall advertisement, according to GforGames. The Korean site is temporarily unavailable at the time of writing, but the URL reveals that the device is not up for pre-order just yet, but interested customers can take advantage of a registration page to receive more information as soon as it becomes available.

The whole scenario sounds a bit familiar, as Samsung also pulled a similar scheme with its current flagship smartphone. After launching the original Galaxy S5, the company also unleashed a Galaxy S5 LTE-A model. LG is apparently following in Samsung's footsteps.

The device featured in the advertisement features Cat 6 LTE-A, touting network speeds that are "three times faster than broadband." The next-generation LTE-A network technology can achieve download speeds of up to 300Mbps, indeed marking great improvements over broadband.

Other than the faster speeds, however, it remains unclear just what else is different with this new LG G3 model. Previous rumors hinting at an LG G3 Prime version suggested that it would come with a more powerful processor as well. While the original LG G3 packs a quad-core Qualcomm Snapdragon 801 chipset, the Prime variant is rumored to come with a faster Snapdragon 805 processor. This model is rumored to deliver 4K video support, enhanced gaming, and more top-notch features.

It all sounds quite exciting, but keep in mind that LG has yet to officially announce this new LG G3 version. At the same time, such a model will likely not make its way to U.S. shores anytime soon, as upgrades to LTE-A technology are yet to come.
