Galaxy S7 devices are equipped with an octa-core Exynos 8890 system on a chip and 4GB of RAM in China. In the United States the S7 uses the quad-core Qualcomm Snapdragon 820; unlike Exynos, this SoC supports older CDMA networks that are extensively used by carriers in these markets. The heat from the processor is transferred with a 0.4mm thick water-to-steam heat pipe cooling system. The S7 includes either 32, 64 or 128 GB of internal storage (in most markets only the 32 GB model will be available). Storage can be expanded using a microSD card.
