Pictures of the rumored Galaxy S4 Active have appeared online thanks to GSMArena. The Active is said to be a ruggedized version of the Galaxy S4, meaning it will be water and dust resistant. The device features a quad-core 1.9GHz processor with Adreno 320 GPU. This means it's likely using a Snapdragon 600 chipset.
The Galaxy S4 Active features quite a bit different styling. It uses a metallic shell and features three hardware buttons, something the Galaxy S4 doesn't have. We still don't have an official confirmation for the Galaxy S4 Active, so for now I would take this with a grain of salt.
