The first benchmarks of Samsung's 1.2GHz Galaxy S II -- we saw the 1GHz variant tested previously -- are rolling in, and it's fast. Almost suspiciously so. Its speedy dual-core Exynos CPU pulled off a 3,053 in Quadrant and scored double what the similarly specced HTC Sensation did in Smartbench2011. Those scores also represent a more than threefold improvement over the original Galaxy S. Of course, these are purely synthetic benchmarks and may not translate into an equally improved experience in day to day use. We'll know for sure when we get our hands on one for a proper review in the coming weeks. Full benchmarks are after the break.
