International or Korean version?

view story

http://forum.xda-developers.com – the korean version of s3 says to have 2gb ram and also still have the quad core exynos 4412 chip. while the international just have 1gb of ram. but what is the other differences of the two actually? because i've been searching the net and some articles says that it has 2gb ram and just have dual core dragon chipset. and what are the advantage of korean and international version? because i live in philippines so maybe there are some things that aren't working on korean version here in my place. thanks in advance! :D (HowTos)
