The A7 keeps Apple king of the hill for its 64-bit processor, operating system and apps. Galaxy S5 contains Qualcomm's new Snapdragon 801 SoC, also unveiled in Barcelona. That's a 32-bit quad-core processor running at 2.5GHz with 2 GB of RAM, double that of the iPhone. The iPhone comes with 16, 32 or 64 of storage; Galaxy offers only 16- or 32-GB models, but its microSD card slot can add as much as 128 GB more. The slot also allows for file I/O, something no Apple mobile can do.
