Although it might be little comfort for some of us hardware junkies who insist on having the best version available, for most people a recent comment from Samsung's Mobile Chief, J.K. Shin suggests we have nothing to worry about when it comes to the two different CPU versions of the Samsung Galaxy S4. According to Shin, it really doesn't matter which chip is in your Samsung Galaxy S4. Either the Snapdragon 600 or the Exynos 5 Octa-core will offer nearly identical experiences. He suggested that most consumers will not be able to tell a difference between the two devices, despite what benchmark numbers one can laud over the other.
He explained that the issue which required there to be two separate versions had nothing to do with LTE compatibility and was only a supply and demand problem. He said, "We use multiple different sources. It's a sourcing issue."
This news is not surprising and for the most part most of us who follow the industry have been saying exactly this, but it's still great to hear it confirmed straight from the source.
