The Galaxy S7 is powered by Samsung's own Exynos 8890 processor in most territories, including here in the UK. Our US cousins get the more general, off-the-shelf (but still highly capable) Snapdragon 820.
Whichever chip you get, it will offer radically better performance than the Galaxy S6. Samsung claims that both will offer 30% better performance than the Galaxy S6's Exynos 7420 64-bit octa-core CPU. The phone's also got a memory upgrade, with Samsung having loaded the Galaxy S7 with a staggering 4GB of RAM.

Our own extensive hands-on time with the Galaxy S7 bears this performance boost out. Games in particular absolutely fly on this phone, whether it's the fast-paced 3D racing thrills of Asphalt or the detailed 2D puzzling of Lara Croft Go.
The iPhone, meanwhile, has the dual-core A9 chip and 2GB of RAM. That combo matched the S6, and even exceeded it in general usage, but Samsung holds the advantage - at least until the iPhone 7 arrives.
Our multicore CPU benchmark tests showed that the Galaxy S7 had a clear lead over the iPhone 6S for high-end tasks.
