Xiaomi has just launched Redmi Note 4 in India at a starting price of Rs 9,999 ( check here ). Older Redmi Note 3 which was launched last year sells for the same price. The newer Note 4 is powered by Qualcomm Snapdragon 625 Octacore processor while the older Note 3 came with Snapdragon 650 hexa core processor. Is it a worthy upgrade ? Read on.
Xiaomi, instead of going for a more powerful chipset like Snapdragon 653 or even 652, chose to put SD625 on Note 4. Snapdragon 625 is not at all a bad processor – in fact it can do most of tasks Snapdragon 650 can without any issues. However, in terms of raw performance, SD650 on Note 3 is better than SD625 on Note 4.
Battery Backup : Snapdragon 625 seen on Redmi Note 4 has a 14nm architecture – which is newer, more energy efficient resulting in better battery backup. Snapdragon 650 is made on a 28nm architecture – which is more power hungry, resulting in using more battery. So Battery Backup wise Redmi Note 4 is a clear winner here.
CPU – Processing Speed : SD650 is a hexacore chipset with 2 powerful Cortex A72 cores and 4 Cortex A53 cores. SD625 is an Octacore processor with all 8 cores A53. Since SD650 has 2 A72 cores, it should be perform better comparing to SD625. So in terms of raw performance, Redmi Note 3 on 650 has a upper hand.
Graphics : Redmi Note 3 has a Adreno 510 GPU while Note 4 has a slightly less powerful Adreno 506 GPU.
Real Usage Scenarios : You wouldn’t notice much difference between these two devices in your day to day tasks. For gaming and graphics performance, Note 3 has an edge. Note 4 has better looks, better camera, 4GB ram variant and comes in Matte Black color. The price is still Rs 9999 for the base model. So in my opinion, Note 4 is it is still a worthy upgrade to Redmi Note 3 even though it has a slightly less powerful processor on board.
