The Samsung Galaxy S4 flagship phone is split into two versions – with Snapdragon 600 chipset and with Exynos 5 SoC. Could there be a third one with Snapdragon 800? Quite possibly, according to an AnTuTu benchmark result for the SHV-E330S, which showed up with a 2.3GHz CPU.
That is supposedly the Galaxy S4 LTE Advanced model for Samsung’s home country of South Korea (which is where the benchmark was run too). The SHV-E330S received a Bluetooth certification for Asia a while back.
The device ran Android 4.2.2, which is what Samsung’s latest have, though the score is on the low side for a Qualcomm Snapdragon 800 chipset. This could be an early prototype though, there are no other mobile chipsets at the moment that clock this high.
South Korea is expecting the launch of an LTE Advanced network in September and the 800 chipset has built-in support for the new tech. That allows theoretical download speeds of 150Mpbs.
By the way, recently we saw rumors that the Samsung Galaxy Note III will pack the Snapdragon 800, so this could be the next Note instead of Galaxy S.
