I have been trying to figure this out for the longest. The International version has a Exynos quadcore processor with 1gb of ram whereas the US version has a Dual Core Snapdragon processor with 2gb of ram. Which version would likely be the better version. Should the quad core with 1gb of ram out perform a dual core with 2gb of ram? Is it likely that the US version would be a little laggy considering its only running on a dual core or does the 2gb make up for its speed?
