It appears that the lack of LTE support can be crossed off the list of reasons why most Galaxy S4 smartphones will feature Qualcomm 600 chipset rather than Samsung's Exynos 5 Octa.
Taking to Twitter, Samsung said that Exynos 5 Octa supports LTE in all its 20 glorious bands, which means that lack of LTE is not one of the reasons why most regions will actually get Qualcomm 600 equipped Galaxy S4 rather than the Exynos 5 Octa.
The most obvious reason, which we wrote about on multiple occasions, is that Samsung simply can't make enough Exynos 5 Octa chips in order to cover the demand and thus Qualcomm 600 was obvious choice. Recently revealed benchmarks of the Exynos 5 Octa equipped Galaxy S4 shows that this chip certainly has enough power to cope with other flagship phones and it is currently the fastest smartphone on the list.
Of course, the fact that Exynos 5 Octa does support LTE does not mean that Galaxy S4 equipped with it will support it, but we will be sure as some Galaxy S4 review with Exynos 5 Octa is bound to show up sooner rather than later.
