Samsung and HTC released their flagship device this year and followed it up with their Prime versions. Now even LG has released the Prime version of the G3 in South Korea and have named it as LG G3 Cat.6. with the latest Snapdragon 805 processor.
Cat.6 denotes LTE-A speeds of up to 300Mbps (peak download rates), something the Snapdragon 801 processor (with its Cat.4 LTE modem) cannot offer. This device is not expected to be available outside of Korea just like its Samsung and HTC counterparts.
