The Galaxy S III was launched with a quad-core processor. Samsung confirmed that if you want an LTE version then you would have to sacrifice the quad-core processor for a dual-core one as the Exynos chip doesn’t support the LTE radio. The US, Japanese and Canadian versions of the Galaxy S III are all the similar and run on a dual-core processor with LTE radio and 2GB of RAM. It has been reported that new version of the S III is likely to be launched in Korea which will go on to have a quad-core processor and LTE radio on board. If this version of Samsung is launched it will go on to be the first ever quad-core processor equipped Smartphone that will have LTE support as well. The new Korean LTE Galaxy S III will feature quad-Core Exynos application processor and an LTE modem chip separately. This will make the handset gain 9mm in thickness which is a 0.4mm gain on the standard model. It will also have 2,100mAh battery.
