Samsung has announced that it's bringing its 14nm Exynos chips to cheaper smartphones. These are smaller chips that are both more efficient and more powerful, and given that the company is already putting the technology to use on competitors' chips (namely, Qualcomm's), it's no surprise to see the chip appear in more phones. Until now, Samsung's only put the FinFET-made (that's 3D-structured) 14nm processors in its best -- and most expensive -- phones. That's about to change.
