With the original Galaxy S4 getting a processor bump to Snapdragon 800, how could the water resistant variant be left behind? A benchmark listing at GFXBench shows a Korean variant of the Galaxy S4 Active (SHV-E470S) having MSM8974 which is nothing but the Snapdragon 800. Just like the Galaxy S4, the Galaxy S4 Active will most likely have the processor upgrade to support the LTE-A network which SK Telecom recently launched. The Snapdragon 800 is a quad-core processor with a clock speed of 2.3GHz and supports LTE-A network that can give data speeds to up to 150Mbps.
This particular model seems to be Korea only but it shouldn't be far off when Samsung releases a similar device for the international market.
The Galaxy S4 Active supports IP67 standard for dust and water resistance and features 2GB of RAM, 8MP and 2MP cameras, 5-inch Full HD (1080p) TFT LCD display, 16GB of internal storage, microSD slot, Bluetooth 4.0, Wi-Fi, NFC, 2600 mAh battery.
