Apart from the model number and the carriers, there is no much details about the technical specification of the Galaxy S5 Active.
The upcoming Galaxy S5 Active will be a cheaper variant, with a few downgrades in terms of hardware configuration.
For an instance, the Galaxy S4 Active features an LCD display and eight megapixel camera when compared to the Galaxy S4 which comes with Super AMOLED display and a high resolution 13 megapixel rear camera.
It is possible that we might get to see the similar changes in the Galaxy S5 Active with an LCD display and a 13 megapixel camera instead of a 16 megapixel unit, notes Sammobile.
The similar SM-G870 model has been recently rumoured to be as Samsung Galaxy S5 Mini with a considerably lower price.
