With the release of the iPhone X, Apple's A11 bionic processor has demonstrated its powerful capabilities! Qualcomm will certainly not sit still. According to foreign media, Qualcomm is expected to announce the relevant information of Qualcomm Xiaolong 845 processor at the 4G/5G summit held in mid-October this year, and will announce the news of its listing at the end of the year.

An interesting fact is that the processing power of modern smartphones is much higher than that of home computers 10 years ago, and the energy consumption is only a fraction of the latter. Maybe we shouldn't give this saying a "fun" attribute, but it's true, and the smartphone's processing power will be stronger and stronger - faster and smarter than previous smartphones.

It's not a big surprise, the performance of every generation of smartphones comes from newer and better system-on-chip. It is the "brains" of smartphones, including a central processing unit and graphics processing unit, as well as imaging processors, sound output circuits, a small amount of ultra-high-speed memory called "cache", and other circuits - all of which are integrated. On a silicon chip smaller than a penny coin.

At present, Qualcomm Snapdragon 835 chip is one of the fastest on-chip systems in the Android smartphone camp, and is used in a large number of high-end Android phones, including Samsung Galaxy Note 8, Galaxy S8, LG V30, HTC U11, Sony Xperia XZ1 and One plus 5T. However, Qualcomm may have developed a higher-chip system with better performance than the Snapdragon 835, and will be announced soon.

Our understanding of Snapdragon 845

phoneArena said that Qualcomm's new generation of flagship Snapdragon platform - probably called Snapdragon 845 - is similar to Snapdragon 835 in many respects. First, it may still use a similar eight-core design: four high-performance cores can easily handle high-performance loads, and four high-performance ones handle less demanding performance than cores. The system decides which kernels to use and the number of cores based on the tasks that need to be processed.

In addition, the performance of the Snapdragon 845 chip is expected to increase compared to the Snapdragon 835. Compared to the Snapdragon 835, the high-performance core in the Snapdragon 845 is 20% faster when dealing with single-threaded tasks. The high performance of the Snapdragon 845 is 18% better than the core processing power, and the performance ratio is increased by 15%. The increase in performance and performance ratio may be due to Qualcomm switching to a new processor core – a high-end Cortex-A75 based on ARM design and a mid-range Cortex-A55 processor design. In contrast, the core of the Snapdragon 835 chip is based on the Cortex-A73 and Cortex-A53.

According to the news, the next generation of Snapdragon 845 clocked at 2.5GHz, single-core running score of 2600 points, multi-core running points of more than 8500 points, compared with 835 performance improvement of more than 35%, but compared to Apple A11 is still quite a lot. Apple's A11 single-core running this year has more than 4,000 points, and the multi-core running points have already exceeded 10,000. In terms of performance, it is still ahead of Android.

It is reported that there are three vendors competing for the launch of the 骁龙 845, namely Samsung, Xiaomi and Google, among which Samsung S9 and Xiaomi 7 have been exposed. Samsung will also launch the Exynos 9810 next year, and its performance can compete with the Dragon 845.

There are also rumors that the Snapdragon 845 chip will be manufactured using a 10 nanometer process, but it is not clear whether it will use the first or second generation 10 nanometer manufacturing process. The second generation of 10 nanometer manufacturing process can further improve the chip performance ratio.

In addition to more advanced core design and manufacturing processes, the Opteron 845 chip will be optimized for advanced applications such as biometrics, speech recognition and artificial intelligence. The Adrenno 630, the integrated graphics processing unit of the Snapdragon 845, is not only good at running 3D games, but also rendering a new generation of virtual/augmented reality experiences.

Equally important, phoneArena said, the Snapdragon 845 chip also integrates Qualcomm's own X20 LTE modem. This news is ok, and the familiar X20 LTE modem specifications include a 1.2Gbps downlink rate and a 150Mbps uplink rate.

It seems that the CPU of the Android camp still can't beat Apple. What do you think about the 骁龙 845?
