The SoC comes with the upgraded Mali T-760 GPU, which is an improved version of the GPU that is already used on the Exynos 5 chip. Perhaps the international version of the Samsung Galaxy Note 5 will be employing these chips when the next iteration of the high-end phablet launches in about a year from now.
A device powered by the Exynos 7 Octa can simultaneously record high definition video using the back and front-facing cameras. This is because of the built-in dual Image Signal Processor (ISP). This feature supports 16MP 30fps (rear) and 5MP 30fps(front) video capture during simultaneous video recording.
