Speaking of Texas Instruments, I believe many mobile phone players will be familiar with it. In the Android single core era, the OMAP3430 series provides sufficient hardware support for Motorola's classic product milestones. Although the OMAP4430 and 4460 in the dual core era are not as good as Samsung Exynos 4210 in performance, their combined strength cannot be underestimated. Today, Samsung I9260, the top chip OMAP4470 of TI, is evaluated.

This article tests the I9260 engineering machine, which may be different from the officially launched version.

Samsung Galaxy Premier Parameters:

In terms of parameters, the I9260 is more like a product combining the characteristics of the I9250 and the I9300. From the SoC point of view, the OMAP4470 is a comprehensive enhanced version of the OMAP4460 used by the I9250, and the screen is also consistent with the I9250. It is also a 4.65-inch Super AMOLED HD with a resolution of 1280 * 720. In other aspects, it is the same as the I9300. For example, the rear camera with 8 million pixels and a F2.6 aperture has not shrunk in front, and is still 1.9 million. Samsung's unique somatosensory movements also remain. The most difficult thing is that the I9260 still supports NFC. Of course, in the configuration list, we are most interested in the OMAP4470 SoC. This chip has not appeared in previous mobile phones. This evaluation will also focus on the performance of this SoC.

performance

Performance is the focus of this evaluation. For the time being, Galaxy Premier is the only mobile phone that uses OMAP4470. What is the performance of the legendary strongest dual core processor?

First, let's take a look at the SOC of OMAP4470. It is a dual core processor produced by the famous Texas Instruments, based on the Cortex-A9 architecture, with a frequency of 1.5GHz and a manufacturing process of 45nm. OMAP4470 is equipped with PowerVR SGX544@384MHz , the graphics processing capacity is about the same as that of the iPhone 4S SGX543MP2@200MHz At the same level. This GPU has also become a highlight of OMAP4470. While the resolution of the I9260 is 1280 * 720, does the SGX544 support 720P resolution in actual use?

Theoretical test

We have made a preliminary measurement of the performance of the I9260 through some scoring software.

Antu rabbit evaluation

The score of the I9260 is ideal for dual core mobile phones. The score exceeds 10000. The 3D score in the GPU is even higher than the Mali400MP4 used in the Galaxy Note II. It seems that the strength of the SGX544 is really strong ▼

Vellamo

This is the benchmark test for web pages. HTML5 is not inferior to the average quad core processor, while Metal is relatively low ▼

Nenamark 2.4

As for the graphics performance of the I9260, it is very desirable. First, use Nenamark to test it. The frame number is high, but it has not reached the full frame status ▼

GLBenchmark 2.5.1

This software can accurately display the graphics performance of mobile phones. The theoretical score of I9260 is slightly higher than that of Tegra3 mobile phones and slightly lower than that of HiSilicon K3V2. For a dual core processor, such GPU performance is also satisfactory ▼

Actual test

Browser javascript performance

Here, Chrome Beta V25 is used for browser performance testing. Sunspider has achieved an ideal result, breaking 1000ms. It seems that OMAP4470 outperforms many quad core processors ▼ by virtue of its high frequency and excellent single core efficiency

Reference score (the lower the score, the better)

Galaxy Note II ：806ms，One X+：1162ms，Nexus 4:1268ms

Google V8 javascript test

I9260 also performs well in this test, and its score is about the same as that of Tegra3 on the same frequency ▼

Reference score

Galaxy Note II ：2608，One X+：2271，Nexus 4:1871

Video soft solution

A 1080P ref=16 60fps mp4 video is used for the soft solution test. BSPlayer 1.8 is used for the soft solution. Because the video software uses multithreading, the I9260's performance is certainly inferior to that of a quad core processor ▼

Reference score

Galaxy Note II ：31，One X+：18，Nexus 4:24

Game measurement

The part of game testing is the focus of this performance test. Here, the popular large-scale games Modern Warfare 4, Extreme Fast Car 17 and NBA2K13 are used for testing, among which Modern Warfare 4 and Extreme Fast Car 17 are used for additional testing. When the game is running, run FPS Meter 1.3.5 at the same time (the mobile phone needs root) to monitor the real-time frame number of the game. In addition, some games need to be added to the Google service package. After the root is required, use ADB push ▼

NBA2K13

The I9260 performs well in NBA2K13, with an average frame number of 35, which can meet the requirements of smooth operation, and the special effects are also at a high level. Reflectivity on the ground and player details reach the level of high-end image quality ▼

Modern Warfare 4

Modern Warfare 4 is a game with very high performance requirements for mobile phone GPU. It is a "hardware killer" game. The I9260 runs smoothly under the default image quality. The number of frames exceeds 40. In the scene with few people, there are even many near full frames. In the complex scene, it drops to about 30 frames, reaching the level of smooth operation. However, in terms of image quality, the default image quality of the SGX544 is not high. It is probably at the same level as Qualcomm's Adreno320. There is still a gap between the full special effects of the Mali400MP4 ▼

Since the performance of the SGX544 can fully meet the requirements of 720P resolution in terms of low special effects, we further squeeze the performance of the GPU through some special methods. First of all, we will explain the Gameloft game's setting standards for image quality. Gameloft games judge the special effects that are enabled according to the phone's model information. Samsung's I9300, N7100 and other models will be automatically identified as the highest special effects. But do other mobile phones have nothing to do with full special effects? In fact, we can achieve our goal by modifying the model information in the mobile phone system. To obtain root permission, use the re manager to edit the text of/system/build.prop, as shown in the figure, change the word "I9260" to "I9300", and then restart to enter the game again ▼

The effect after the model information is modified is shown in the figure. It can be seen that the details of the gun body change greatly, the light and shadow effect is much better, and the details of the scene are also very obvious. The overall effect is much better than that before the modification, but the overall frame number is also very obvious, with an average of less than 30 frames, which cannot meet the requirements of smooth operation. Of course, this is a very demanding additional requirement ▼

Top Speed Car 17

Jipin Flying Car 17 is also a game with high configuration requirements. I9260 performs abnormally in this game, with less than 20 frames. The author speculates that ▼ is caused by poor compatibility of engineering machines

photograph

The camera parameters of the I9260 are completely the same as those of the Galaxy S3 and Galaxy Note II. The hand feeling of taking photos is also very similar. The picture quality is good and the imaging speed is fast. The following is a sample photo (click to view a large picture) ▼

temperature

As OMAP4470 remains at the 45nm level, and the CPU frequency is not low, the slightly higher temperature is also expected. The test results show that after the modern war 4, which has been running for about 15 minutes, the highest body temperature is around the earpiece, reaching 40 degrees. If the handset is in hand, it will be close to 45 degrees ▼

signal

The signal performance of the I9260 is fairly good, at the same level as the Galaxy S3 ▼

Endurance

The endurance performance of the I9260 is satisfactory, and it has no problem when it is used for one and a half days. The hard solution of the I9260 is very power-saving, and it can even take more than 10 hours for hardware to decode MP4. Of course, if you are running a large game, the power consumption will rise faster.

Summary

As a dual core mobile phone, the I9260 may give a feeling that it is not as good as the popular quad core mobile phone. However, from the perspective of actual use, the performance of the I9260 is not inferior to some quad core flagship phones, especially in terms of graphics performance, and even more powerful than some quad core processors. Of course, due to the lack of CPU cores, some multithreaded applications will be inferior to quad core mobile phones. In addition to SoC, the performance of the I9260 is at the same level as that of the Galaxy S3. If you like the Galaxy S3 and feel that it is too big or worried about the "font door", you can consider this small battleship of the Galaxy.
