The latest news coming from Samsung’s homeland suggests that the next Samsung Galaxy Note III will be powered by Qualcomm’s Snapdragon 800 platform instead of the octa-core Exynos we expected.
It could be that Samsung is having troubles manufacturing its chipset or it could be that it just sees the Snapdragon 800 as more powerful and likely cheaper. Also, the Snapdragon 800 platform has an embedded LTE radio, while Samsung needs a third-party hardware to enable LTE support on Exynos.
The Snapdragon 800 chipset has a quad-core Krait 400 processor that can be clocked up to 2.3GHz. An Adreno 330 GPU is in charge of the graphics and it supports up to 4K video playback and recording. Snapdragon 800 also comes with a new generation LTE chip that supports category 4 (Up to 300Mbps downlink, up to 75Mbps uplink) and 7.1-channel sound. I think they made the right choice.
