The Samsung Galaxy S 4 will be shipping around the world in one of two CPU configurations; The Qualcomm manufactured 1.9GHz Snapdragon 600 CPU or the Samsung designed 1.6GHz Exynos Octa-Core CPU which features ARMs Big-Little CPu configuration which pairs a 1.6GHz Quad-Core A15 processor for the heavy work with a 1.2GHz Quad-Core A7 CPU for the every day tasks to give eight cores in total.
SAMMobile has released a listing for all of Europe, Africa, Asia and most importantly Australia and according to them there will be two models, the GT-i9500 which will carry the Exynos Octa or the GT-i9505 which will feature the Snapdragon 600 and Australia will be seeing the GT-i9505; which means we’ll be getting the Snapdragon 600 in our Galaxy S 4.
The inclusion of the Snapdragon 600 makes sense with Qualcomm recently confirming in a Blog post that confirms the inclusion of Category 3 LTE Support, which includes the 1800MHz band that is in use by all three major mobile operators in Australia.
The Snapdragon 600 is clocking some pretty serious benchmarks at the moment and with the Exynos Octa currently LTE-less it makes good sense to go this route with LTE markets in Australia expanding fairly rapidly. Either way the Galaxy S 4 a monster of a phone.
Update: Thanks to a number of commentors the clock speed was incorrect and has been swapped around.
