We already know there's two variants of Samsung's flagship smartphone, the GALAXY S III available. Firstly we have the quad-core Exynos 4 Quad, and the US-bound dual-core Qualcomm S4 variant. But, Samsung have released a third variant of the S III for the South Korean market.
This latest variant sports Samsung's own quad-core ARM-based SoC, and LTE baseband chip. The 'CMC221S' LTE baseband chip was developed in collaboration with AP, and will allow network subscribers of local telcos SK Telecom and KT to connect users up to high-speed connections. The chip supports 2G, GSM, 3G, WCDMA, 4G, and LTE, which makes it capable of working in virtually every country on Earth.
Not much is known about the chip, but it's assumed its manufactured on a 40nm process. Samsung Electronics' CEO of IT and IM, Jong-Kyun Shin has said that the company plans to have more designs with its own baseband chip and that the Korean GALAXY S III LTE demonstrates "Korea has the fastest LTE" and "we are already considering moving on to VoLTE".
