The devices are powered by a Snapdragon 805 processor from Qualcomm, which will help set the Galaxy Note 4 apart from the competition because it has so far only been used in Korean versions of the S5 and G3.
The Snapdragon 805 offers better performance across the board compared to Qualcomm's existing Snapdragon 800 processors, which are used by most current high-end smartphones. The processor also lets Samsung implement LTE-Advanced, a network technology that offers speeds up to 300Mbps in the version Samsung has integrated. For it to work, mobile operators have to upgrade their networks.
The Galaxy Note 4 will be available across the world next month and the Galaxy Note Edge will be available in "select markets through Samsung's retail channels, e-commerce and carriers later this year," the company said. Pricing wasn't immediately available.
