Xiaomi Mi 5s: Does it Feature a Snapdragon 821 or Snapdragon 820 Chip?

by Habeeb Onawole 10

Xiaomi launched the new Mi 5s and Mi 5s Plus yesterday and according to the company both phones use Qualcomm’s new Snapdragon 821 processor. But the question on people’s mind is if the Mi 5s indeed sports a Snapdragon 821 chip seeing as its clocked at 2.15 GHz which is the maximum clock speed for the snapdragon 820 while the Mi 5s Plus is clocked at 2.35 GHz.


Someone decided to confirm that and checked the CPU details using popular app CPU-Z.

The app shows the Mi 5s indeed uses a Snapdragon 821 chip which also goes by the model name MSM8996Pro. However, the CPU is not the only thing that got under-clocked, the GPU is also under-clocked at 624MHz instead of  653MHz like that of the Mi 5S Plus.

Although the Xiaomi Mi 5s might have an under-clocked processor, it still has a higher clock speed than the original Mi 5 whose Snapdragon 820 chip is clocked at 1.8GHz.

Snapdragon 821 Clock speed

Why Xiaomi has decided to lower the clock speed of the CPU and GPU on the Mi 5s is currently unknown but we can only assume it must have been for the best reason. The lower clock speed affects both variants of the Mi 5s as seen in the image above.

    It’s probably to give an incentive to consumers to buy Mi5S Plus…

    What about customer that prefer more compact phone which can be handle with one hand like me?
    Totally regret going to 5.5″.. Looking for a chance to get back to 4.6-5.2″

      You can get original mi5.
      Im so happy I sold my samsung s6 and dont look back.

      Apple did offer smaller screen device (but not smaller though), so you can expect from Chinese copycats to offer something similar. However, problem is that Apple ‘s iPhone 5s did not find big market for itself…
      Well.. .even with Sony that has fu**d up for a first time with their compact model, there are some very good 5’ options.

      Mi5s will offer a smaller screen and Mi5s plus will feature a 5.7″ one.

        What I mean is why tey underclock oth the cpu and gpu i mi Mi5s. Some prefer high spec + smaller size + cheap. But Xiami underclock both Mi5s variant.

    Well, SD821 clocked higher than SD820 still has better efficiency. This underclocking would mean much lower power consumption and better performance than SD820. I don’t see a problem here.

    • Raky_b

      Thing is that SD821 IS just a overclocked SD820.
      No other differents except that and a number. So, we can say that sd820 is basically underclocked sd821!?
      But you are right about lower power consumption.

      • divis200

        It’s faster than sd820 because slower cores have 2.0GHz clock speed.

          All that does is make it a battery hog.
