Thanks.Actual real world use, the Dual Core Snapdragon chip performs just as well as the quad core in the international version.
In fact in some ways the Dual core snapdragon is a better chip, and you'd probably get longer battery life with it. At least for LTE versions, since the Quad core version to have LTE needs to have another chip added to it to support LTE. The Qualcomm Snapdragon chip has it built in.
Good article on the Snapdragon S4. http://www.anandtech.com/show/5559/...ormance-preview-msm8960-adreno-225-benchmarks
