Dude, are you a noob? Redmi Note 3 has Snapdragon 650 Processor which is a hexa core processor consisting of 4 x cortex A53 cores and 2 x cortex A72 cores. The A72 cores are more powerful than the A53 cores which is why Qualcomm renamed it to 650 from 618 to differentiate it from the 61x line up. Lenovo K4 Note has a MedaiTek 6753 Octa Core processor consisting of 8 x A53 cores. It doesn’t matter whether a processor is octa core or hexa core, what really matters is how powerful are the custom cores. Look at Snapdragon 820, it’s just a quad core processor but still trashes octa and deca core processors. The Snapdragon 650 completely destroys the MediaTek 6753 processor. Just check the Antutu benchmark of both the phones, Redmi Note 3 Snapdragon variant is miles ahead of K4 Note. Redmi Note 3 scores 75K on Antutu where as K4 Note scores just around 40K in Antutu benchmark. People say benchmarks don’t give a real picture, and I agree but benchmark measures the performance of a device and the better the score, better the performance in heavy applications
