in fact, through the above parameter comparison, we can see that snapdragon 660 and 652 have the following differences:
1 In terms of manufacturing process
Qualcomm snapdragon 660 adopts more advanced 14nm process, while Qualcomm snapdragon 652 adopts the previous generation 28nm license process, so theoretically speaking, Qualcomm snapdragon 660 has more advanced power consumption and heat control
2. Core frequency
although these two chips belong to 8-core design, the more advanced A73 core is adopted by the Qualcomm snapdragon 6660, with the dominant frequency up to 2.2GHz, while the highest frequency of the Qualcomm snapdragon 652 is 1.8GHz
3. In terms of network mode
Qualcomm snapdragon 660 also has more comprehensive network support, supporting X12 / x13 LTE, so the high-speed network experience is obviously better than snapdragon 660< In terms of GPU, GPU 512 seems to be better than GPU 510, but it does not represent the actual performance. The specific performance depends on the following specific tests

in terms of basic parameters, compared with Qualcomm snapdragon 652, Qualcomm snapdragon 660 has obvious advantages in terms of process, dominant frequency and network mode. As for the gap in all aspects, the following small series will bring the data of running points<

from the run test point of view, although the multi-core performance of Qualcomm snapdragon 660 is not as good as snapdragon 652, the single core, graphics processor and overall run score are much better. As the latest snapdragon 600 series mobile platform of Qualcomm, snapdragon 660 adopts 14nm manufacturing process and has low power consumption. At the same time, the introction of new kryo 260 CPU and Adreno 512gpu makes its multi-core performance excellent
the following is the location of snapdragon 660 and 652 in the mobile phone CPU ladder, as shown in the figure below<

the position of Xiaolong 660 and 652 in the sky ladder map
as for this, I believe you have some understanding of the difference between Xiaolong 660 and 652, At the end of the article, let's talk about the two representative SOC models:
snapdragon 660 representative model: oppo R11

the representative models of snapdragon 652 are Nubia Z11 max, oppo R9 plus, vivo X6S plus, etc<

conclusion:
well, through the above tests, we can finally come to a conclusion. Which is better, the Qualcomm snapdragon 660 or the Qualcomm snapdragon 652? Obviously, it is the Qualcomm snapdragon 660. Although the multi-core performance of the snapdragon 652 is better than that of the snapdragon 660, there is a certain gap between the single core performance and GPU performance of the snapdragon 660, and the memory is also at the level of the previous generation processor. On the whole, the snapdragon 652 has a certain gap with the snapdragon 660.

2. Apq8064 Pro is actually another name of apq8064t. It belongs to snapdragon 600 series and uses krait300 architecture to build a four core adreno320 GPU

the msm8260a Pro used by Xiaomi 2A belongs to S4 Pro Series, which adopts krati300 architecture al core and adreno320 GPU

the same architecture, the same running frequency, of course, more cores is better.
