Samsung 14nm yields much better than what anyone expected

FUD Zilla writes the fact that Samsung already has a working 14nm SoC surprised the mobile industry. The site says everyone is impressed with the yields Samsung is getting with its 14nm process as most industry figures expected that Samsung would release two versions of its Galaxy S6, one with the Exynos for a few small markets and one with the Snapdragon 810 for most of the world.
What happened is that 14nm yields for Exynos 7240 were significantly better than Samsung or anyone else in the industry expected. This includes Qualcomm, Intel, TSMC - you name it - and people still cannot believe that Samsung recovered so well from disastrous 20nm yields in its fabs. This is the reason why Samsung decided that most of its Galaxy S6 and S6 Edge should ship with Exynos and a smaller number with Snapdragon 810 SoCs.

The 14nm Exynos 7240 uses Cortex-A57 and Cortex-A53 cores and delivers a slight increase in speed that got up from 1.9GHz with Exynos 5433 to 2.1GHz for A57 cores and from 1.3GHz to 1.5GHz on A53 cores. At the same time 14nm means that Samsung needs less power to run the chip, while reaping more performance.
