When Xiaomi 1S was launched last year, it was officially explained that "S" means Super, or enhanced version. This year's Rice Noodle Festival Xiaomi 2S has been released on the Internet. It appears as an enhanced version of Xiaomi 2. The improvement is in SoC and camera (32G version). How much is the performance improvement of Xiaomi 2S brought by the new SoC? Let's verify it through a series of tests.

From the data point of view, on the surface, the frequency of Xiaomi 2S is only 200 MHz higher than that of Xiaomi 2. For ordinary users, it is literally the difference between four core 1.5GHz and four core 1.7GHz. Is the difference really so small? Actually, the SoC of Xiaomi 2S has been upgraded from APQ8064 to APQ8064T (i.e. Snapdragon 600) The core is upgraded from Qualcomm Krait 200 to Krait 300. The GPU keeps the Adreno 320 unchanged while improving memory performance. Because of this change, Qualcomm claims that APQ8064T has 40% performance improvement and 5% power consumption reduction compared with APQ8064. Our current measurement also focuses on this problem.

testing environment

Mobile phones: Xiaomi 2S, Xiaomi 2 (both Xiaomi use the latest MIUI-3.4.12 System) Nexus4 、

Galaxy Note II、 Galaxy S4 、 Butterfly 、 Optimus G Pro

Test software: Anrabbit evaluation, Vellamo Anthare 3D 、 BaseMark X 3DMark, BSPlayer, Modern War 4, Real Racing 3, Top Speed Racing 17 PPSSPP

Since Xiaomi 2S and Xiaomi 2 are highly consistent in architecture and system, we can ensure that they are compared in the same system, software and test environment, and the test results will most intuitively show the improvement of APQ8064T over APQ8064.

Kiss, run a minute?

Although the score does not fully represent the experience, it can reflect many performance problems, especially for two SoCs with similar architecture, the score is more meaningful.

Antu rabbit evaluation

This is a conventional score running software. Last year, Xiaomi 2 was released as the "little prince of score running", and its score is invincible. Of course, Xiaomi 2S will continue this tradition, passing the test, 25078 run points of Xiaomi 2S It is also a relatively high level in mobile phones. Compared with Xiaomi 2, we should not only look at the total score, but also the score of each item. It can be seen that Xiaomi 2S has advantages in many aspects. From the comparison of tests, RAM performance, CPU integer performance, CPU floating point performance and 3D drawing performance have improved to varying degrees. It is worth noting that the 3D drawing performance test of Anthare is actually greatly affected by the performance of the CPU (see the special test below), so these performance improvements are actually the performance improvements of the CPU itself, and have nothing to do with the GPU ▼

Vellamo

This is a web testing software launched by Qualcomm. Xiaomi 2S has performed well, and has improved to some extent compared with Xiaomi 2, HTML5 score is 1991, Metal score is 745 ▼

Compared with other mobile phones, the Vellamo test scores of Xiaomi 2S are also among the best ▼

Calculation of Pi In the past, we used to test the CPU of PC, but now Android phones also have corresponding applications for calculating Pi. The following is a test for calculating 10 million bits, It took 35 seconds. Because the floating point operation capability of Snapdragon series processors is very powerful, such scores are temporarily the highest level at present ▼

GLBenchmark 2.7

The new 2.7 version of the old GPU test software puts forward new requirements for GPU performance. At the same time, the 2.7 version includes 2.5 tests. The frame number of the Xiaomi 2S is not different from that of other mobile phones using Adreno 320, Offscreen frames of 2.7 and 2.5 are 13fps and 33fps ▼ respectively

Anthare 3D

Compared with the overall score of Anthare's evaluation, the 3D test of the segmented piece is more accurate in measuring the GPU performance. The frame number of Xiaomi 2S is higher than that of Xiaomi 2, Up to 26.9 frames 。 The increase is up to 20%, and the frame number can be increased because of the performance improvement of CPU and memory ▼

It should be noted that the resolution in this test will also affect the performance, so the frames of Xiaomi 2S, Xiaomi 2, Nexus 4, and Note II are more comparable ▼

BaseMark X

This software uses Unity 4.0 engine, introduces a large number of particle effects, advanced lighting effects and post-processing, so it will exert great pressure on the GPU of mobile phones, On Screen (720P) score is 15.765 frames, Off Screen (1080P) score is 7.255 frames 。 The following is a screenshot of Xiaomi 2S's performance ▼

By contrast, Xiaomi 2S has not improved much compared with Xiaomi 2. They are basically at the same level. They are all at the highest level of mobile phones ▼

3DMark

The mobile version of PC's old brand graphics card test software supports cross platform comparison, including iOS Android and Windows RT devices can be compared, but only the Android version is available for the time being. 3DMark tests include Ice Strom tests based on OpenGL ES 2.0. Below are the screenshots of Xiaomi 2S scores and the average score ranking. The average score of more than 11000 is the highest level of all devices at present, especially in the author's test High score of 12275 ▼

From the comparison of sub test frames, the improvement of Xiaomi 2S is mainly in the Physics Test, that is, the test to test the CPU efficiency. The improvement range reaches 7 frames ▼

Is the score unreliable? Let's see the practical application

Sunspider web page Javascript

This is a highly referential test to measure CPU single thread performance. The lower the test score, the better. The browser used is Chrome Beta. The score of Xiaomi 2S is also the best among Qualcomm processors tested by the author. Compared with Xiaomi 2, it has also been greatly improved, Test result is 947.9ms 。 Although the impact of frequency increase is involved here, the gap is sufficient. It can be seen that the increase of Krait 300 compared with Krait 200 is still obvious ▼

After using the browser, the Javascript performance is more excellent, breaking the 900ms threshold. This phenomenon also appeared in the test of Optimus G Pro of Snapdragon 600, and the performance of Xiaomi 2S is better than Optimus G Pro ▼

The following is a comparison of the performance of some models using Chrome Beta. It can be seen that the single threaded Javascript performance of Krait 300 can already compare with the CPU of Cortex-A9 ▼

Test summary

From the performance comparison, the improvement of Xiaomi 2S is obvious compared with Xiaomi 2, Several tests focusing on CPU increased by 22% on average , which is close to the official 25% increase. In the test focusing on GPUs, since the GPUs they use are completely consistent, it is also expected that the increase will be small. The Snapdragon 600 is indeed much better than the previous Snapdragon S4 Pro in terms of performance. Many users only understand the Snapdragon 600 as the overclocking version of APQ8064. Now, 13% frequency increase, bringing more than 22% performance improvement It is enough to see that the Snapdragon 600 is not so simple as overclocking, and the performance of the same frequency is significantly enhanced. For Xiaomi 2S, its price is only 50 yuan higher than that of Xiaomi 2. It can be seen that the price performance of Xiaomi 2S has reached a new level ▼
