The mobile processor technology used by mobile phones is changing with each passing day, and the speed of update iteration is beyond imagination. We have seen many 4-core, 6-core and even 8-core SoCs appear on the market, some of which have even reached 2.7GHz. Under the strong propaganda attack, what are their actual performance? This article is a horizontal comparison of the performance of high-end SoC of mainstream mobile phones.
First of all, we will not use the scoring application of our common general performance tests such as Anthare and Master Lu in this test. This type of application mixes too many tests, and some scoring standards are also controversial. Moreover, the results of different versions are very different, so it is of little reference significance.
The SoC models and relevant information participating in the test are as follows:
Exynos 5422：28nm， Quad core A15 1.9GHz+Quad core A7 1.3GHz, Mali-T628mp6 533MHz
Exynos 5430：20nm， Quad core A15 1.8GHz+Quad core A7 1.3GHz, Mali-T628mp6 600MHz
Exynos 5433：20nm， Quad core A57 1.9GHz+Quad core A53 1.3GHz, Mali-T760mp? 700MHz
Snapdragon 801 (MSM8974AC): 28nm, quad core Krait 400 2.5GHz, Adreno 330 578MHz
Snapdragon 805 (APQ8084): 28nm, quad core Krait 450 2.5GHz, Adreno 420 600MHz
MT6595：28nm， Quad core A17 2.2GHz+Quad core A7 1.7GHz, PowerVR G6200 (dual core) 600MHz
Kirin 925：28nm， Quad core A15 1.8GHz+Quad core A7 1.3GHz, Mali-T628mp4 600MHz
Tegra K1：28nm， Quad core A15 2.2GHz, 192 core Kepler GPU
A7：28nm， Dual core Cyclone 1.3GHz, PowerVR G6430 (quad core)
A8：20nm， Dual core new version Cyclone 1.4GHz, PowerVR GX6450 (quad core)
CPU performance
CPU is the most central part of SoC, which relates to the processing speed of the whole system and is also the focus of many manufacturers' propaganda. Ordinary consumers have almost no concept of true eight core, four core 2.5GHz, 64 bit processors and other terms, and the processors participating in the horizontal review are also high-end products of various companies, including Exynos 5433, Snapdragon 805, MT6595, A8 and other high-end models. As a reference, we also used Tegra K1 (only tablet products for the time being) with unusual and strong specifications for comparison.
Pi
Pi is a test of CPU floating point performance, which is more sensitive to frequency under the same architecture. We use a test that calculates 10 million bits. It is the time when the calculation is completed. Of course, the shorter the time, the better.
From the test results, Exynos 5433, MT6595 and Tegra K1 performed very well. The explosion of Exynos 5433 is undoubtedly due to the unprecedented strength of the CPU core. The MT6595 and Tegra K1, on the other hand, are due to the high frequency of the CPU, which directly improves the computing performance. The former can reach a terrifying 2.4GHz when it is a single core, and it is not surprising that the Cortex-A17, which has excellent single core performance, can achieve good results.
RAR performance test
RAR performance test is an additional function in the official application of RAR. It can test the compression performance of mobile phones, mainly measuring the performance of CPU L2 cache. This test involves multiple threads, so various "true eight core" processors will have great advantages here. In addition, the main frequency of the processor will also have a significant impact on the test results.
From this test result, we found that Samsung Exynos 5433 is not as good as two products using the old kernel. It is really a bit "unscientific", perhaps because the current system does not support Cortex-A57 enough. However, Qualcomm Snapdragon's two processors only have four cores, so they suffer a lot here. In addition, the performance of Snapdragon 801 and Snapdragon 805 on the same frequency is relatively close, and even the latter is worse than the former. It can also be seen that HTC handles Snapdragon series processors better. The MT6595 is invincible, leaving other competitors. Although Tegra K1 is a quad core processor, its high frequency is close to that of an eight core processor in this test, which is enough to show its fierce performance.
Sunspider 1.0.2
This is a web page Javascript test. It is aimed at the CPU single core performance. Compared with the CPU of the architecture, it is very sensitive to the frequency. In addition, because this test is conducted by using web pages, different browsers will also have a great impact on the results. Here, the iOS device uses Safari, the Samsung Exynos series processor uses its own browser, and other Android devices use Chrome Beta, so the final results are for reference only.
From the results, there is basically no big surprise. The comparison between Exynos 5422 and Exynos 5430 shows that this test is relatively sensitive to the CPU frequency, and the CPU gap between the two can also be shown by 100MHz. However, the high configuration Snapdragon 805 is not as good as the M8 Snapdragon 801 in the same frequency, which is a problem of system optimization.
GPU performance
With the development of mobile phones, GPU has participated in more graphic rendering operations, and its position is becoming more and more important. The performance of GPU has also developed rapidly. NVIDIA's Tegra K1 even moved the desktop level Kepler architecture to a small SoC, and also gained overwhelming performance advantages, but it has not yet been applied to mobile phones.
GFXBench 3.0
The old GPU performance test is divided into Manhattan and Tyrannosaurus Rex scenarios in the high pressure test of version 3.0, and applied to OpenGL ES2.0 or even 3.0 technology. The test scenarios have very high requirements for GPU. What we are doing here is off screen testing (unified rendering of 1080P images). It is a pure GPU performance comparison that does not involve the resolution of the device itself.
From the comparison results, Tegra K1 stands out from its competitors. The mobile phone is the most eye-catching of Apple's A8 and Qualcomm Snapdragon 805, followed by Samsung Exynos 5433. However, the MT6595 and Kirin 925 are not strong enough in GPU scale, so there is a big gap between their GPU performance and that of top processors.
3DMark
It is also a well-known graphics performance test. We are familiar with it from 3DMark on PC. We use the Ice Storm Unlimited test, which also does not consider the resolution of the device itself. Ice Storm Unlimited test is divided into two GPU test scenarios and one CPU test scenario.
From the results, it seems that this test is of little reference significance. In particular, the graphics performance test of Exynos 5433 and Exynos 5430 have won or lost each other. The level of Snapdragon 801 and Snapdragon 805 are equivalent, which shows that there seems to be a problem with its test standards. While Tegra K1 still maintains an overwhelming advantage, except for K1, the GPU performance of Apple A8 is the most eye-catching.
Attachment: Storage performance
A1 SD Bench
This is an application to test the storage read/write speed of Android devices. It can also test memory copies. Today's high-end mobile phones like to promote eMMC 5.0, which is a new memory standard specification. Mobile phones using it will have a huge advantage in reading and writing speed compared with mobile phones using eMMC 4.5, which can be clearly reflected in this test.
In comparison, we can see that the Galaxy Alpha Galaxy Note 4、 The high configuration Galaxy S5, MX4 and other products have great advantages over eMMC 4.5 products. At the same time, we have also added the comparison between ordinary TF and high-speed TF cards (Sandisk Extreme Pro series), which can be used as a reference for users.
