For those unaware, Samsung currently licenses processor cores – called Cortex – from ARM (so do other chip makers with 64-bit SoCs, including Qualcomm for the Snapdragon 810) and then simply puts them in its Exynos chips. According to sources based in Korea, Samsung expects to “see results by Q1 next year at the latest” when it comes to the development of its custom processor cores. That's not exactly a full-on confirmation that an SoC with Samsung's custom cores will indeed make its way to devices in the beginning of 2016, but it is certainly possible we will see this chip in the Galaxy S7, given how Samsung has been getting serious about the mobile processor business.
Samsung has also been reported to be working on a custom in-house mobile GPU, though it is expected to be ready for mass production as early as mid-2015.
