Snapdragon 820 may feature 3.0GHz Kyro CPU cores manufactured at Samsung

Samsung is said to manufacture the SoC, which Qualcomm revealed during the unveil of the Snapdragon 820 would be built on a "leading-edge FinFET process." Samsung switched to a 14nm FinFET manufacturing process this year with the latest-generation Exynos SoC, which is used in the Galaxy S6 and Galaxy S6 edge.
This isn't the first time we're hearing about Samsung being a possible manufacturer for the Snapdragon 820. In April, a report out of Re/code — citing anonymous sources — suggested that Qualcomm was looking to shift production to Samsung from Taiwan's TSMC in a bid to regain the South Korean manufacturer as a client.
The Korean report states that HTC, Sony, and Xiaomi will be the first manufacturers to test the Snapdragon 820. The shift to a 14nm process would give Qualcomm the ability to design a more energy-efficient SoC, an issue that has plagued the chip vendor this year
