According to new reports out of its home country of South Korea, Samsung is set to start mass producing the Exynos 8890 chipset for the Galaxy S7 at some point in December. This SoC, also known by its codenames M1 or Mongoose, is going to be the first Samsung-made one to feature custom CPU cores. The Korean company will not be using ARM designs anymore, like it has so far for every single one of its past Exynos chips. Going with custom cores is significant because at the moment only Intel, Apple, Qualcomm, AMD, and ARM have their own CPU designs in the semiconductor market. So Samsung's going to be in good company in this regard. And apparently this will allow it to reduce costs, better optimize the chips for its smartphones, as well as gain a competitive edge in the market. The Galaxy S7 could in fact have three different chipset variations inside, each model being sold in certain markets only. One of those will be the Exynos 8890, while another is set to be Qualcomm's upcoming Snapdragon 820. Source 1 (in Korean) Source 2 | Via 1 Via...
