Faster Samsung Galaxy S4 may be in the works

A new version of Samsung's Galaxy S4 may soon surface, at least based on a series of benchmarks.
New benchmarks from AnTuTu Labs were uncovered by GSMarena and other blog sites. The benchmarks highlight a new international LTE-Advanced version of the Galaxy S4 with a Qualcomm quad-core Snapdragon 800 processor clocked at 2.3GHz. Tagged with a model number of I9506, the phone is outfitted with Android 4.2.2 Jelly Bean.
In comparison, the original Galaxy S4 is powered by a 1.9GHz quad-core Snapdragon 600 chip and supports 4G LTE. Another variant released last month in South Korea comes with a Snapdragon 800 processor and supports LTE-A. But the benchmarks list that one as different from the new leaked model and as delivering a slightly slower performance.
