The "cheating" event of Huawei Glory was announced on the Anthare homepage last month, and it was found that Huawei Glory Quad Core locked the GPU frequency at the highest frequency during the running of some scoring software to achieve better scoring results. Later, after the netizen test, in addition to the GPU problem, some mobile phones in the market also have "dirty" CPU frequencies when running points. This time, the problem is that when the mobile phone enters the rabbit software, it will automatically lock at the highest frequency. The following are the test results of some popular mobile phones.

testing environment

mobile phone (by platform):

APQ8064: Xiaomi 2, Nexus 4, HTC Butterfly

Exynos 4412：Galaxy Note2、MX2

Tegra3: HTC One X+, ZTE U985

K3V2: Glory quad core

MSM8960：Optimus LTE2

testing software ：

Android System Info Pro (used to detect CPU utilization and real-time frequency)

Angu Rabbit Evaluation 3.0.3 Official Version

GLBenchmark 2.5.1

test result

First with Take the test results of the Android System Info Pro as an example to illustrate the test method. First, we open the Android System Info Pro software, and then open the floating window for CPU detection. Then we enter the Apsara rabbit evaluation, GLBenchmark and other scoring software to observe the real-time frequency change of the mobile phone (the whole process does not score, but only enters the software to see the CPU frequency). For example, Xiaomi 2 is still in low frequency, that is, there is no problem.

One X+

Obviously, One X+has a problem of "cheating". The CPU utilization rate is only 2%, but the real-time frequency has soared to 1.6G. Some readers may wonder, isn't One X+Tegra3 1.7G? In fact, the frequency of 1.7G can only appear when there is a single core, and the maximum frequency can only reach 1.6GHz when there are four cores at the same time , more detailed tests can be viewed Evaluation of One X+ 。

Four cores of glory

Although there is a problem with the Glory quad core in the GPU, the CPU is relatively "honest".

No problem, the occupancy and frequency are very low.

MX2

No problem, the occupancy and frequency are very low.

Nexus 4

There is no need to explain this... The frequency reduction problem of the Nexus 4 is famous. How can it lock the highest frequency? (Nexus Pink: You are high-end black!)

No problem.

HTC Butterfly

Poor HTC was shot again. The CPU utilization is very low, but the frequency is still stable at 1.5G high frequency. In addition, the author also opened GLBenchmark for testing, and the result is still automatically raised to the highest frequency

However, when running general software, there will be no high frequency locking.

LG Optimus LTE2

The following is the Optimus LTE2 tested by netizens. This machine uses MSM8960 1.5G dual core CPU, and also has the problem of automatic frequency locking.

analysis

Why do some brands want frequency locking? Mobile CPUs are dynamically variable frequency, and the voltage and frequency of the CPU will be automatically adjusted according to different load levels of the CPU. Under normal circumstances, if you cut into the running score software from a low load situation and then test it, it needs a frequency up process, and in this process, the running score will be worse than that in the high-frequency situation. In addition, the frequency fluctuation of CPU will not be ruled out in the process of score running. For example, the practice that some mobile phones are locked in high frequency as soon as they enter the scoring software can avoid this problem and enable mobile phones to reach the highest score in the scoring software under normal conditions. This practice is similar to the "white list" of Huawei Glory Four Check Run Score Software, which was denounced by Anthare. But this time, the white list changes the CPU frequency. The author believes that these practices do not belong to cheating, which can only be said to be the compromise practices of the manufacturer to cater to the users' abnormal running point mentality, so that the mobile phone can be "fully fired" in the running point software. Score scoring is indeed a reference to the computing performance of mobile phones. However, when many manufacturers in the industry specifically optimize for this software, it seems that the whole atmosphere is very unhealthy.
