Rumors has it, that the next Galaxy S smartphone would feature a next-gen Exynos 5450 system. It’s a quad-core chipset based on the new Cortex A15 architecture, which offers significant improvements over the old A9 one in every aspect possible, ranging from power efficiency to raw processing power. According to the rumors, the processor in the Samsung Galaxy SIV should be clocked at 2,0GHz, suggesting blazing-fast speeds. Again, these are only rumors and should be taken with a pinch of salt.
