Qualcomm Snapdragon 600
It may not be as flashy as Samsung's eight-core Exynos 5 Octa processor, but Qualcomm's Snapdragon 600 is a worthy successor to the ultra-prevalent Snapdragon S4 mobile SoC from 2012. The Snapdragon 600 was released earlier this year but is already powering some of the top smartphones on the market, including the HTC One, the LG Optimus G Pro and select models of the Samsung Galaxy S4. The 28-nm quad core CPU runs at up to 1.9GHz and also comes with an Adreno320 GPU, plus integrated LTE, Bluetooth 4.0 and 802.11n/ac wireless support. Designed to improve the Snapdragon's performance per watt and power-optimization, the 600 model is a worthy successor to the Snapdragon S4.
