Samsung announced the successor to the Galaxy S the Galaxy S II back in MWC 2011.
Back then, Sammy announced that the SGS II will sport a 1 GHz dual-core Exynos processor and an ARM Mali 400 GPU. However, reports are flying in that Samsung has bumped up the clock speed on the handset to 1.2 GHz.
This piece of news has even been confirmed by Samsung’s Eesti Facebook page. The reason behind the increase in this speed bump is unknown at the moment.
It may very well be possible that the performance of the Exynos chip was not up to the mark, thus forcing Samsung to increase the clock speed. Due to this speed bump, Samsung has pushed back the release date of the Galaxy S II until late-May or early June.
It is unknown whether this will affect the processor speed of the Tegra 2 variant of the Galaxy S II, which will sport a 1 GHz dual-core Cortex-A9 CPUs.
