At the Qualcomm Technology Summit in December last year, Qualcomm released the 2018 flagship mobile platform, the Snapdragon 845 mobile platform, which will be launched in early 2018.
Near the MWC (World Mobile Communications Conference), it is also time to meet this flagship chip, so this Snapdragon 845 mobile platform will join hands with the world's first launch has become a hot spot of the media.
Recently, Qualcomm demonstrated the performance score of the Snapdragon 845 mobile platform to the media at the US headquarters in San Diego. From the perspective of running software, the overall performance of the 845 is nearly 30% higher than that of the previous generation 835, and the overall performance of the iPhone X test is higher than the latter. This means next year's Android flagship product, performance or catch up with iPhone X.
The Snapdragon 845 mobile platform revolves around innovation, immersive experience, artificial intelligence, security, connectivity and performance, and the experience of using these six items.
éªé¾™ 845 mobile platform internal structure
Let's take a look at the overall configuration of the Snapdragon 845: the Snapdragon 845 processor uses a 10 nanometer LPP process, in which the graphics processor uses Adreno 630 (GPU), the highest download speed of 1.2GHz X20 LTE modem, WiFi, video graphics Processor Spectra 280 (ISP), and Hexagon 685 coprocessor (DSP), Qualcomm AqsTIc Audio high-fidelity audio, CPU with four 2.8GHz big core + four 1.8GHz small core + 2MB cache Kryo 385 CPU Built-in mobile security chip, another new independent memory in the 845.
In the era of dual-camera popularization, the Snapdragon 845 configuration was upgraded again, and the digital signal processor was upgraded to 685 DSP by the 682 used before 835. In addition, the Spectra 280 and Adreno 630 graphics processing unit (GPU), which are responsible for the image processor (ISP), are separately proposed to set up the visual processing subsystem for the comprehensive improvement of graphics. The vision processing subsystem captures up to 64 times higher dynamic range color information than previous generations. The graphics processor Adreno 630 can be more entertaining. In this regard, Qualcomm is talking about XR.
What is XR (eXtended)? You can understand that it is a combination of VR (Virtual Reality) + AR (Augmented Reality) + MR (Mixed Reality).
The Snapdragon 845 is the first mobile platform to support indoor space positioning with six degrees of freedom and instant positioning and map construction. Simply put, when you use the Snapdragon 845 processor to play virtual reality products, you will recognize the obstacles in front and remind the user.
The artificial intelligence aspect is also one of the characteristics of the Snapdragon 845. It is somewhat different from the current AI chip. Qualcomm believes that the independent chip may have a large loss on the power consumption and thermal energy of the processor, and considers the 845 processor terminal characteristics. By mobilizing the various units in the module to mobilize artificial intelligence to handle the power consumption.
Currently, the Snapdragon Neuroprocessing Engine (SNPE) SDK is compatible with Google TensorFlow and artificial intelligence networks such as Microsoft.
In terms of battery life, Qualcomm said that the mobile device equipped with the Snapdragon 845 supports QC4.0 fast charging. The official said that charging with QC4.0 for 15 minutes is 50% full. At the same time, the 845 also saves power through AI. According to Qualcomm, the 4K ultra-high-definition video can last up to 4 hours, and it can bring more than 3 hours of battery life to the wireless VR all-in-one device. The wireless VR machine experience of more than 3 hours is displayed, supporting ultra-high-definition voice calls of more than 2 days. .
Network connection is Qualcomm's specialty. This generation of Snapdragon 845 processor is equipped with X20 LTE modem, supports multi-gigabit Wi-Fi, can increase peak speed by 20%, and can achieve 1.2Gbps per second, basically only 3 In the minute, you can get the lower 3GB HD movie.
In general, in addition to the performance improvement of the Snapdragon 845 mobile platform, XR and AI will be a future direction. Let's take a look at its performance through the evaluation software. Note: The prototype of the Snapdragon 845 is not a production version, the iOS version is 6.3.6, and the Ann Bunny version is 7.0.4.
éªé¾™ 845 mobile platform performance testLet's first take a look at the application of Xiaolong 845 in Antu Bunny. Ann Bunny is the most commonly used application in mobile phone evaluation. It can test CPU overall performance, RAM memory test, 2D/3D graphics performance test and data storage. Comprehensive testing of the performance of I/O.
A11 processor performance running points used by Xiaolong 845 and iPhone X
Since Ann Bunny has not been updated in the iOS version, the test score may be biased. The overall performance of the Zuolong 845 is 267,288 points, which is much higher than the previous A11 processor of 21,633,000 (right).
We use Geekbench for testing. It is worth mentioning that this application is also an application for discovering the iPhone "down frequency gate". It not only supports iOS, Android, but also Windows, macOS, Linux and other systems.
Both use Geekbench to run sub-data
Or the Snapdragon 845 (left) and the A11 processor (right) used by the iPhoneX, the performance of the Apple A series is still its strength still leading 845.
Single-core performance is particularly close to 845, nearly doubled, and multi-core performance is still closely related to A11.
Of course, running points is only a measure of the overall performance of the processor is not the only one, Qualcomm is more important to this Snapdragon 845 is the user's comprehensive experience, such as artificial intelligence, data security or good network connectivity, etc., so when When we got the mobile phone equipped with the Snapdragon 845 mobile platform, we found it excellent.
It is reported that Xiaomi will launch the Xiaomi MIX 2S based on the Xiaolong 845 mobile platform in the MWC (World Mobile Communications Conference), and Samsung will launch the flagship S9 in the first half of the year. Who is this "global debut"? ,let us wait and see!
EtherNet/IP refers to the "EtherNet Industrial Protocol". It defines an open industry standard that combines traditional Ethernet with industry protocols. The standard was jointly developed by the International Association of Control Network and Open Device Network Suppliers with the assistance of the Industrial Ethernet Association and launched in March 2000. EtherNet/IP is based on TCP/IP series protocol, so the use of the original form of OSI layer model in the lower 4 layers. All standard EtherNet communication modules such as PC interface cards, cables, connectors, hubs and switches can be used with EtherNet/IP.
