Snapdragon 845 20 ask 20 A help you understand the 2018 mobile phone market

Beijing on December 6, 2017, Qualcomm announced a new generation of flagship processor in Hawaii - Snapdragon 845. As we all know, Snapdragon 835 mobile platform dominated the market for 17 years, Andrews flagship model, stable power control and not bad 835 performance output to get the user's praise. Snapdragon 845 processor advent whether it can re-write the myth, take a look at the 'Snapdragon 845' 20 things you know.

1, who will be the first to use Xiaolong 845 mobile platform?

By convention, Samsung is the first to release the world-class mobile phone series cover cell phones equipped with the latest Snapdragon mobile platform, such as the upcoming Samsung Galaxy S6. Recently there is news that the Samsung Galaxy S6 will be held in January next year CES appearance at the conference, if true, it means that we can experience the power of the Snapdragon 845 earlier.However, Samsung generally will be released around March every year S Series new products, there is no special reason not to break the convention, therefore The above message remains to be discussed.

2, a brief summary Snapdragon 845 main upgrade point

Snapdragon 845 mobile platform upgrades: The new Qualcomm Kryo 385 CPU, 25% performance increase, the new Adreno 630 GPU, 30% performance improvement, power consumption reduction of 30%; integrated X20 LTE modem, second generation gigabit LTE Modem (the highest down 1.2Gbps ), A 20% speed increase over the X16, the first generation; the new Hexagon 685 DSP, which offers artificial intelligence and the new Qualcomm Spectra 280 ISP for more comprehensive photo taking.

3, Xiao Long 845 adopted by the LPP in the end where?

Although the Snapdragon 845 mobile platform and the previous generation 835 have adopted the 10nm process, but Snapdragon 845 and the previous generation has the essential difference, that is, the Snapdragon 845 LPP process technology, and the Snapdragon 835 for the LPE.

Samsung has two process technologies at 10nm node: 10nm LPE and 10nm LPP, which represent low power consumption and high performance, respectively. Samsung introduced the performance of 10nm LPP process is 10% higher than the 10nm LPE, And energy-saving 15%. Thus, Snapdragon 845 with 10nm LPP process is more surprising.

4, Snapdragon 845 play games so what is not? Eat chicken card is not card?

If the Snapdragon 835 GPU is not used Adreno 630 is a small regret, then in this generation 845, the user has finally been met.

What is Adreno GPUs? Adreno GPUs are snapdragon processors that provide game console-quality 3D image processing capabilities for mobile devices that provide faster image processing for games, user interfaces and high-performance computing tasks, Calculated key components.

5, Snapdragon 845 can use 5G it?

According to the Snapdragon 845 specifications, it is fully equipped with 5G network strength, more accurately, Snapdragon 845 has been prepared for the 5G network era, because it inherits the X20 LTE-level modems.

5G network theoretical downlink speed of 10Gbps (equivalent to the download speed of 1.25GB / s or so), while the Snapdragon X20 LTE as the world's first chip to support LTE Category 18, up to 1.2Gbps download speeds, fully equipped with a 5G network Ability, the rest, is waiting for the advent of 5G network era.

According to the Ministry of Industry and Information Technology, the work plan of China's IMT-2020 (5G) Propulsion Team and the 5G commercial plan of the three major operators, large-scale trial networking will be conducted in 2018 and the relevant international agencies will announce the 5G After the formal standard, start 5G network construction in 2019, the fastest in 2020 formally commercial 5G network.

6, Snapdragon 845 with SPU than my security encryption phone is also powerful?

What is the security of mobile phones? I think the higher security of the phone, the bad guys can not easily be used, and Zhang San's mobile phone, Zhang Sanneng can use, even if other people took, can not use.

17 years is the first year of universal coverage, full screen means that the positive cancellation of the fingerprint can be unlocked Home key, facial recognition and then began to rapidly develop into mainstream.But facial recognition is really safe? Speaking of the current Apple headaches, then The face is unlocked.

Because iPhone X Face ID allows two people at the same time to unlock the phone.For example iPhoneX first entered the owner's face information, the second person constantly unlock with a password, Face ID will continue to learn to adjust, resulting in the second face of the information was Mixed into the first face of the message, you can do two faces to unlock, it also shows that the iPhone X is not absolutely safe. Andy Greenberg, Wired magazine's journalist, also experimented, eventually, with testers Ammar Malik successfully unlocked Mom's iPhone X.

To this end, Qualcomm Snapdragon 845 provides system-level security, including SPU, HLOS , TrustZone layer 3. First of all, under the 'SPU (Security Processing Unit)'. This is a similar information locking module, and it is not only for face recognition, fingerprinting and other biometric, but also file encryption, secure transmission and other functions , All the biological information, encryption keys and other sensitive content will be targeted protection, all locked within the SPU unit.

The power supply unit of the SPU unit is separated from the CPU and GPU, which means that it can be started before the rest of the phone to provide full-time security protection.

HLOS and TrustZone also serve as a secure payment and information management technology, providing users with further shackles on privacy-related content such as password payment, which means that instead of using a mobile phone that uses a security chip separately from the market, With the Snapdragon 845, the so-called security encryption phones have to bow down.

7, Snapdragon 845 fast charge what is the upgrade?

Snapdragon 845 will be fast charge technology upgrade to Qualcomm QuickCharge 4, from the official PPT point of view, in theory charge from 0-50% charge just 15 minutes, charging rate is very alarming.

8, Xiaolong 845 third-generation artificial intelligence in the end where?

This year in the iOS and Android two flagship lineup, the AI ​​board can be described as a highlight of its battle - Apple introduced the A11 bionic chip, Huawei Mate 10 Kirin 970 also joined the NPU artificial intelligence.

The Snapdragon 845 is not behind, in the field of AI although it does not provide an independent neural network engine unit, but its 'smart point' lies in the use of a distributed architecture.

In a nutshell, the Snapdragon 845 still uses artificial intelligence (CPU), GPU and DSP to support artificial intelligence technology, which is the third generation of heterogeneous AI computing design. This generation of heterogeneous AI computing design will focus on 'VR' The main application is to simplify the shooting of pictures and videos, enhance VR gaming experience, and make voice interaction more natural.

9, the performance of Xiao Long 845 to upgrade it?

As we all know, the daily use of mobile phones play a decisive role in determining the CPU is the first in the architecture, the 894 from the 845Kryo 280 Snapdragon upgrade to the Kry0 ​​385, but the number of up 105, spanning very large, the configuration, Snapdragon 845 The CPU features four high-performance cores up to 2.8GHz and four high-efficiency cores up to 1.8GHz, improving performance by 25% -30% compared to the previous generation and high-performance cores. The energy-efficient core Of the performance increase of 15% and according to Samsung's semiconductor process description, LPP LPE upgrade compared to only about 10-15%, the overall performance improvement is still quite considerable.

Then again, any theory that is not actually tested is a piece of paper, the intuition of performance improvement has to wait until the real machine is available for posting.

10, the conference said the immersive experience is what the ghost?

Qualcomm said, Snapdragon 845 for consumers to shoot a movie-level video, breaking the boundaries of reality and the virtual world.As long as it is integrated Qualcomm Spectra 280 ISP and Qualcomm Adreno 630 visual processing Subsystem.These new architectures bring high performance, realistic movie-level video capture to flagship mobile devices. Immersive experiences are mainly aimed at VR and AR.

Qualcomm also emphasized that the Snapdragon 845 will support room-scale, 6DOF (6DoF) and instant positioning and map building (SLAM) mobile platform, in order to avoid the wall collision and other characteristics.I think Xiaolong The participation of 845 immersive experience plays an important role in the development of VR and AR in the future and accelerates the pace of interaction between virtual reality and reality.

11, equipped with Snapdragon 845 laptop fly it?

Recently, Qualcomm Executive Vice President Cristiano Amon revealed that Snapdragon 845 chip Windows 10 ARM products will be listed in the second half of next year.

In fact, this is not an exaggeration, Snapdragon 845 conference, Qualcomm said that this generation of SoC's target product is only involved in the field of smart phones, access to other areas more than 835 more. According to Snapdragon 845 by the four Kryo 385 core + four small core composition, large nuclear 2.8GHz, small nuclear 1.8GHz, from the process point of view, the equivalent of i5 processor level, driven a computer problem is not large.

12, Snapdragon 845 run points high?

Although there is no real machine Xiaolong 845 release, but with micro-Bo technology hobby i Ice universe speculated that Snapdragon 845's Geekbench single-core run points more than 2,600 points is not a problem, this score than the snapdragon 835's 1900 or so much higher grade.

13, Xiaolong 845 cell phone about how much money?

This depends on the various brands of sales measures, each of the main bright spots are not the same, and the phone is not only a part of the processor, but also includes camera modules, batteries, exterior design, and so on, so there will be no price A phenomenon.

According to the previous generation Snapdragon 835 mobile phone price speculation, equipped with Snapdragon 845 phone price is expected to range from 3600 to 8000.

14, Snapdragon 845 MediaTek X30 much stronger?

Strong and weak are not conclusive, the parameters, MediaTek X30 and Xiaolong 835 belong to the same level, while the Snapdragon 845 compared to the previous generation of CPU architecture, GPU level and process technology is a qualitative leap, the answer is clear .

15, Snapdragon 845 and Apple's A11 'fight', who terrible?

Again, before the real machine equipped with its processor did not come out, any conclusion is negotiable, not much. First look at the latest flagship processor specifications comparison:

Snapdragon 845 Qualcomm as the second 10nm process SoC products, process upgrades to LPP, CPU architecture based on ARM latest Cortex A75 / A55 to do custom, GPU performance improvement of 30%, baseband upgrade to Cat.18, video recording support 4K 60FPS , Hardware solution supports 4K HDR 60FPS.

The CPU of the Apple A11 Bionic Processor uses a six-core design consisting of two high-performance cores and four energy-efficient cores, two of which are 25% faster than the A10 Fusion and four of which are energy-efficient Speed ​​up 70%, and CPU, GPU, performance controller, neural network unit, ISP inside A11 bionic chips are all Apple-designed.

Compared to two processors, can only say that each has its own advantages,

16, Qualcomm Xiaolong 845 full support for artificial intelligence and XR, XR is what?

What is XR? In short, VR and AR are merged together, and we all know that VR can completely screen the real content and bring the user into the virtual world. AR relies on the real world to present interactive content For example, if you park a car on the edge of a road, you can see the engine structure, the space inside the car, the motor power and other parameters through AR eyes. Now the VR and AR can not be integrated, and the former tends to the consumer market , While the latter pay more attention to the enterprise.

XR is the combination of the two technologies, imagine that in the future people may not need a computer office, directly brought XR equipment at home and colleagues can work together to work together to work together, really cool.
