Recently, the famous technology website Anandtech This new Google flagship has been tested for speed and found a very interesting phenomenon, that is, the Nexus 4 The phenomenon of automatic frequency reduction is serious at high temperature, even working at 1.1G for a long time. Later, the Nexus 4 was subjected to a relatively abnormal test, and the test results were directly put into the refrigerator. It was surprising to find that the test results were much higher. Nexus 4 is still hard to get. We use the same SoC What will be the result of the same test? testing environment
Mobile: Xiaomi 2
System: MIUI 2.11.9 based on Android 4.1.1
Test software: GLBenchmark 2.5.1, CPU Spy Plus
Xiaomi 2 uses the same SoC of APQ8064 as Nexus 4, and its GPU is Adreno 320.
In addition, the test software is introduced. GLBenchmark has appeared many times in the author's previous tests. It is a professional GPU test software. In Anandtech's test, it was found that the performance of the "frozen version" Nexus 4 in GLBenchmark 2.5.1 is much higher than that of the Nexus 4 at room temperature, so this test is also subject to this software. CPU Spy Plus is a type of CPU status statistics, which can make statistics on the frequency distribution and time of the CPU in the recent period.
Actual test
First, test at room temperature. The ambient temperature is about 25 degrees. The body temperature is 26.1 degrees on the front and 26 degrees on the back.
In Anandtech's test, we saw that there was a big gap in the performance of Triangle Texture (onscreen), Egypt HD (onscreen), Egypt HD (offscreen), Egypt Classic (onscreen), and Egypt Classic (offscreen) in GLBenchmark 2.5.1 of the frozen Nexus 4 run. The following is the test chart.
This is the Nexus 4 normal temperature frequency distribution diagram tested by AnandTech.
Let's take a look at the scores of Xiaomi 2 at room temperature for these results.
It can be seen that the performance of Xiaomi 2 at room temperature is similar to that of the frozen Nexus 4, and even higher in many tests. Let's look at the frequency distribution of Xiaomi 2.
Xiaomi 2 was at the highest frequency of 1.5G most of the time in the test, Therefore, there is no frequency reduction problem 。
At this point, many readers may think that the test is over, but as“ Love to play computer games ”How can we just give up? If you want to play hard, let's play hard Xiaomi 2 is put into the refrigerator for testing.
The following is the temperature of millet 2 after freezing, 12.7 degrees on the front and 14.1 degrees on the back.
Running score
frequency distribution
It can be seen that the performance of "iced millet 2" seems to be the same as that of normal millet 2, It seems that Xiaomi 2 is better than Nexus 4 in high-temperature resistance.
After the test, the temperature is 26.8 degrees on the front and 28.1 degrees on the back.
Comparison table
summary
Some questions:
1. Is the high temperature frequency reduction of Nexus 4 an individual problem?
2. Will other mobile phones using APQ8064 have similar phenomena?
3. Can Nexus 4 change this situation by replacing the kernel?
Of course, the answers to the above questions will not be known until we actually get the Nexus 4 and other mobile phones that use APQ8064. The Nexus 4 has recently become a hot topic in the mobile phone industry. It has attracted wide attention because of its high cost performance, but now it has been sold at a high price due to the lack of stock. Even the engineering machine has a sky high price of 3600 yuan. However, such a joke due to the temperature problem is really inappropriate. Some netizens even laughed that "the Nexus 4 is the best mobile phone in Antarctica" and "the performance of mobile phones will be better in winter than in summer". As the "fourth prince", if the Nexus 4 really has such serious problems in terms of heat dissipation and heat resistance, Google and LG should think deeply about the root cause of the problem. The Nexus series is the benchmark model of Android, but do not fall for the Nexus 4.
