We have already published our full review of the Galaxy S4 for the US, which ships with a Qualcomm Snapdragon 600 quad-core processor. In some international markets, the Galaxy S4 ships with Samsung's own Exynos 5 Octa, an eight-core chip that uses ARM's big.LITTLE architecture. We have been using one for the past week, putting it through its paces, although our focus here is to see whether US customers are missing out on any performance.
