The Samsung Galaxy S4 will come in more variants, one of which will boast blazing-fast LTE-Advanced and, as it turns out, Qualcomm's latest Snapdragon 800 chip.

The upcoming Samsung Galaxy S4 LTE-Advanced will apparently pack a Snapdragon 800 MSM8974 quad-core processor clocked at 2.3GHz, a 4.99-inch FHD AMOLED display with a resolution of 1920 x 1080 pixels, a 13-megapixel rear camera, 2GB of RAM, 32GB of internal storage, a battery capacity of 2,600 mAh and Android 4.2.2 Jelly Bean running the show.

News of a LTE-Advanced version of the Samsung Galaxy S4 first broke out a week ago, but now Japanese blog RBMen got hold of the actual user manual for the device headed to Korea.

The new Samsung Galaxy S4 variant with model number SHV-E330 has an MSM8974 CPU according to the user manual, which means it will be the first Snapdragon 800 SoC to debut in handsets this year.

The latest chip from Qualcomm will make the Samsung Galaxy S4 much faster than its brother running on the Snapdragon 600 SoC, while the added support for LTE-Advanced should be able to transmit data at nearly twice the normal speeds.

The world's only LTE-Advanced network is currently deployed by Yota in Moscow, Russia, but South Korean providers will likely jump on board with the new technology soon enough. While carriers in the U.S. and the European Union face various concerns over the technology's complexity, Seoul will likely get a significant head start in implementing the faster LTE Advanced.

Theoretical network speeds for LTE Advanced go all the way up to gigabits, but Yota's live network only promises end-user speeds of 300Mbps. Moreover, the speedy technology was designed from the ground up specifically to support "advanced technology networks," which means it has some pretty neat advantages to offer. LTE Advanced can work with data networks covering femtocells, picocells and various relay technologies in addition to towers.

Such pieces of networks are smaller and more targetable than towers and may one day make up the new world of mobile networks. This would be especially useful in larger cities, where tall buildings and various interferences can result in serious disruptions.

The Samsung Galaxy S4 LTE-Advanced will launch in Samsung's home country of South Korea and it will likely stay there. The company made no mention of availability in U.S. or other parts of the world, so the blazing fast version of the current flagship may be yet another juicy Korea-exclusive.
