Qualcomm Snapdragon 665 vs 675 SOC

Qualcomm Snapdragon 665 vs 675 SOC Specifications Comparison Detail

In this article, we did a side by side comparison of the Snapdragon 665 vs 675. The specifications of these new SOCs from Qualcomm are so similar that it is like a “Spot the difference” competition.  I guess the main difference is in the CPU and GPU where the 675 is a clear winner. These are Qualcomm’s mid-range part where there is a cut-throat competition. The company has been very active in this segment, and we can clearly see the reason why.
