Here's a bit of news that's not terribly exciting but is interesting regardless. Besides just the main CPU, there are some additional subtle differences between the U.S. version of the Samsung Galaxy S4 and the Korean version. The U.S. version uses a separate Fujitsu image processor to handle the eye-tracking features of the device. The Snapdragon 600 can't handle the multi-tasking of this feature as well as the Samsung Exynos 5 Octa-core chip, so they needed to add this additional component to help it function properly.

This was some interesting additional info revealed by the IHS teardown we shared yesterday. This says more about that Exynos 5 Octa-Core than it says about the Snapdragon 600. The Snapdragon is an impressive piece of hardware, but it looks like there is just more headroom potential in Samsung's newest chipset. Impressive!
