Hardware: Snapdragon 808 64-bit Hexa Core, GPU: Adreno 418

Xiaomi MI 4S is powered by Snapdragon 808 64bit Hexa core processor,

The Qualcomm Snapdragon 808 MSM8992 has a high performing CPU with a maximum clock speed of 2,000.00 MHz. It has 6 core(s), resulting in extremely efficient multi-tasking when compared to dual core processors.

As a result of following the Harvard architecture, the CPU has a separate Level 1 instruction and data cache leading to a slight improvement in performance over a unified Level 1 cache. The instruction cache is only used for storing instructions and executes in a sequential manner. The data cache stores data used by instructions; the point of access or storage is generally specified by an instruction.

This processor is based on the Reduced Instruction Set Computing (RISC) design strategy enabling instructions to execute faster, as opposed to the Complex Instruction Set Computing (CISC) design strategy, which is generally slower at executing due to lengthy instructions.

Power Management

By using the big.LITTLE heterogenous computing architecture, the Qualcomm Snapdragon 808 MSM8992 couples slower, low-power processor cores with relatively faster, high-power processor cores in order to reduce energy consumption. The "big" or faster cores are used for computation-intensive tasks such as gaming, whereas the "little" or slower cores are used for less intensive tasks.

Above all, Xiaomi MI 4S this time chooses Snapdragon 808 processor which is the advisable move for most mi fans in the power management and speed improvement.
