How to judge the level of APQ8064| Love to play computer games - 上海419贵族宝贝-上海后花园1314-上海品茶网-阿拉爱上海

We know that in the field of desktop computers, we often hear about CPU and GPU "fitness". Processors with good "fitness" will be more stable in use, and even have room for overclocking. and APQ8064 Qualcomm is the latest leader of Huadan, but the performance of mobile phones using it is very different. We can view the "physique" of some APQ8064 devices using the Android super terminal.

The implementation principle is as follows ▼

General translation:

Basically, the APQ8064 processor is divided into four grades when it leaves the factory, and the rating is based on its operating speed at a voltage level below the nominal value. The four grades are slow, nominal, fast and fast. According to this level, in order to keep the same speed of CPUs of different levels at the factory, the manufacturer will adjust the voltage accordingly. That is, the operating voltage of slow level is the highest, and that of fast level is the lowest. The voltage level is also directly related to the power consumption and temperature of CPU operation, so it is still a reference.

The method is as follows:

Of course, the first thing to prepare is a mobile phone with APQ8064 processor.

The phone needs to obtain Root permission and install super terminal software such as Better Terminal Emulator.

After opening the software, we will see the interface for entering commands. First, type "su" to obtain permissions ▼

Then type "dmesg | grep PVS" to view the SoC level. Here, Nexus 4 is used, and the level is Nominal, which is also consistent with the frequency reduction of Nexus 4 found in our test ▼

Xperia Z， The level is "3" (i.e. Fast level), which is somewhat different from the standard on XDA Developers ▼

Some mobile phones cannot perform this test, and the following screen ▼ is displayed

Although this cannot be tested and cannot be used as a standard to measure processor performance, users with APQ8064 might as well try this test to see how their mobile phones are "healthy".

Finally, the voting results of netizens show that the fast level accounts for the majority
