Samsung Galaxy S4 is currently available in two variants internationally - with Snapdragon 600 and Exynos 5 Octa internals. There's another version, the Galaxy S4 LTE-A, which launched in South Korea with a Snapdragon 800 chipset and LTE-Advanced connectivity.

Leaked AnTuTu benchmarks point to the LTE-A Galaxy S4 getting an international release with the model number is I9506 (the S4 with Snapdragon 600 is I9505).

The benchmark reveals the presence of the quad-core processor clocked at 2.3 GHz. The phone runs on Android 4.2.2 Jelly Bean and the device has managed to pile up 31,123 points in the benchmark, which is about as much as other tested Snapdragon 800 smartphones score. This also suggests a considerable performance advantage over the Galaxy I9500 and I9505 versions.

This is actually better than what the South Korean version of the phone managed. The Adreno 330 GPU easily outperforms the Adreno 320 in the Snapdragon 600, too.

Unfortunately, there is no official word from Samsung on the upcoming variant of the Galaxy S4 smartphone. And until an official announcement comes, you will do well not to get your hopes too high.
