Samsung is expanding its flagship variants with a new addition, the Galaxy S5 LTE-A, packed with a 2K display and upgraded processor but  only in South Korea

Samsung is known to launch different variants after announcing a new flagship. The Korean tech giant launched Galaxy K Zoom and Galaxy S5 Active to earlier extending its flagship variants. With the Galaxy S5 Mini and the rumored Prime model still in works, Samsung has surprised consumers with a new Galaxy S5 LTE-A. The new model features a retina-busting 2K display with highest 577ppi and an upgraded processor.

The launch of Galaxy S5 LTE-A version is clearly a desperate move on Samsung's part to compete with LG's newest G3. Samsung's new launch comes almost two weeks after LG reportedly outperformed the Korean tech giant with impressive sales of the G3 smartphone. According to a report from Korea IT Times, LG G3 was selling 25,000 to 30,000 units per day compared to Samsung Galaxy S5's 7,000 to 8,000 units per day sale during its launch.

Samsung knew Galaxy S5 specs were not good enough to compete with LG G3 in its home market so it decided to up the ante and give it a push in Korea. The highly-touted 2K display in G3 was certainly a winning point for LG, so Samsung not only boosted the screen resolution but also enhanced the processor speed to carry the extra pixels without lagging.

According to ARS Technia via Samsung Tomorrow's Flickr account, the upgraded S5 sports 5.1-inch QHD Super AMOLED display with a resolution of 1440x2560 pixels. Compared to the G3, the Galaxy S5 LTE-A model packs 577 pixels per inch. LG stuffed 538ppi in its current flagship.

The next upgrade in the Galaxy S5 LTE-A is the Snapdragon 805 processor, which makes the new Samsung model the first to debut the overhauled CPU. The original Galaxy S5 and G3 smartphone packed a Snapdragon 801 processor. But the extra push on the S5 LTE-A should most likely keep the smartphone running smoothly. The new smartphone also features the new Adreno 420 GPU, which according to Qualcomm is about 40 percent faster than the Adreno 330 in Snapdragon 805, ARS reports.

Samsung also noted that its LTE-A band allows the new Galaxy S5 to attain download speeds up to 225Mbps. Other features are intact in the upgraded S5 model.

The new S5 variant is only announced in Samsung's home market, the phone maker did not confirm if the handset will cross the borders anytime soon.
