Why is Qualcomm Xiaolong 835 called the first generation God U?

The reason why Xiaolong 835 is God U is mainly compared with Qualcomm's previous generation processor. Since Qualcomm introduced the Xiaolong 800 series processor, many models of products have been criticized for their high temperature and high fever. The most typical examples are Snapdragon 8 10 and Xiaolong 820, two "dragon" processors. Mobile phones with these two processors are very troublesome, either with poor battery life or hot hands, and they dare not play mobile phones with these processors at all.

At that time, many mobile phones paid the price because of the fever problem of Xiaolong processor, and the sales reputation declined. Later, they had to reduce the energy consumption of the processor by frequency reduction, but this would bring about a decline in performance. In any case, consumers are not satisfied, and mobile phone manufacturers put the blame on Qualcomm, but there is nothing they can do.

Therefore, Qualcomm focused on improving efficiency and reducing energy consumption on Xiaolong 835 processor, not only using the latest 10nm process at that time, but also optimizing and adjusting the CPU architecture. In the end, the power consumption of Xiaolong 835 is 25% lower than that of 820, and that of Snapdragon 80 1 is 50% lower. The battery life of Xiaolong 835 is also two and a half hours longer than that of 820. Coupled with the improvement of fast charging standards, Xiaolong 835 was almost.

Because of the excellent performance of Xiaolong 835, the mobile phones equipped with this processor sold well in those years. Even if you play games for a long time, your fever is very small, and you suddenly got rid of the criticism that Xiaolong 835 had a high fever. Although Xiaolong 835 has been discontinued for a long time, it is indeed the key processor for Qualcomm to recover its reputation and increase its market share. Although Snapdragon 845 and Snapdragon 855 have stronger performance and function, they are still not as good as Xiaolong 835, and their prices are much higher.

Xiaolong 800. Very sexy. A flash in the pan.

Snapdragon 80 1. It's very hot. Classic, but it starts to get stuck after 1 year.

Snapdragon 805. It is very hot, and it is not as good as 80 1 when the heat dissipation is not good.

Snapdragon 808. Not hot, but the performance is average, castrated a lot.

Snapdragon 8 10. This is the hottest ever. Once hot, the performance is far less than 80 1.

Xiaolong 820. Very hot. Eat chicken only for the first 5 minutes. After that, it will overheat and get stuck, and start the taxi mode.

Snapdragon 82 1. Very hot. It's just an 820 overclocked version.

Xiaolong 835. Very cold. It's hardly hot. After eating chicken for 4 hours, there is almost no jam.

Snapdragon 845. Very hot, very hot. After eating chicken for half an hour, the congestion is much more serious than 835. At that time, some game phones directly gave up 845 and chose 835, because the game was displayed for a long time, and 845 was seriously retrogressed. Only a few minutes to run with blood.

855, very hot. In order to cool down 855. The manufacturer used water cooling, heat pipes, graphene and oversized copper sheets, and azazel 3 even used an electric fan with 65,438+04,000 rpm to blow. It's simple. If you don't blow, you can't exert your strength.

When you want to add an electric fan to your mobile phone. Is this a joke?

The magic of Xiaolong 835 processor lies in heat dissipation! If you savor it carefully, you will find that the processors before Xiaolong 835 are labeled as "fire dragon", but Xiaolong 835 does not have this title! Why is the thermal control of this processor excellent?

We can find out through the processor parameters: compare two processors, Xiaolong 835 and Snapdragon 82 1, Snapdragon 845 and Xiaolong 835. So you can see the difference between them!

Xiaolong 835 and Snapdragon 82 1:

Xiaolong 835 and Snapdragon 845:

We can see the clue from two comparative pictures:

In fact, before the earliest Snapdragon 8 10, the performance was more obvious: 20nm process technology, the process with insufficient experience in optimizing and debugging the 64-bit A57/A53 architecture published by ARM, and Krait architecture (small core+high frequency) was used in Qualcomm before; But the public version of ARM is (high performance+low performance). Qualcomm tried to apply Krait architecture to ARM, but it would affect the temperature of this phone.

Therefore, under the leadership of several generations of fire dragons, Xiaolong 835 was able to turn the tide and become a generation of frost dragons.

In fact, what can generally be called God U is definitely not the strongest in performance, but the power consumption ratio is very good on the premise of maintaining performance. Qualcomm Xiaolong 835 fully meets this condition. In contrast, the previous terminal processor Qualcomm Snapdragon 660 also meets this condition. These two products can be called a generation of God U, with medium and high collocation.

First of all, both Qualcomm Xiaolong 835 and its upgraded product Qualcomm Snapdragon 845 belong to 10 nm process, which means there is not much disadvantage in process. Although there is definitely a generation difference compared with the 7 nm process of Qualcomm Snapdragon 855, it is absolutely excellent in the first two years.

At the same time, Qualcomm Xiaolong 835, which adopts new nanotechnology, is about 35% smaller than its predecessor Qualcomm Xiaolong 820, and has more than 3 billion transistors. It can be said that from a technical point of view, this processor is really excellent.

This processor is also the first time to adopt Samsung's 10 nanometer process, which has improved qualitatively in technology. And FinFET technology is adopted, which greatly reduces the problems such as leakage. In order to overcome the scaling limitation, the new process also adopts three exposures, stress optimization and improved design.

At the same time, a brand-new Kyro 280 is adopted in the architecture, which is obviously different from the previous architecture mode adopted in Qualcomm. It is also the first semi-custom ARM processor.

There are brand-new dsp and ISP. Most importantly, Qualcomm processor has controlled the power consumption after amplifying the performance to a sufficient degree on this chip. Judging from the feedback from users at the hardware level, Xiaomi 6 equipped with this processor was very good.

That is to say, when this processor uses 8 cores, the frequency is basically the same and the performance is very strong, but the power consumption ratio is not too high. Coupled with a new series of component upgrades, this processor not only has strong enough performance, but also maintains low power consumption, which is why it is called the first generation of God U!

This is the most cost-effective, and now 1200 is used.

82 1 is really hot, it will get hot after playing for a while, and the screen may burn yellow if it is enforced for a long time. 835 has never been used, 845 is much cooler, and the performance improvement is very, very obvious, not hot. 855, at present, the feeling of improvement is not so obvious. Maybe 845 is enough for the game, and the advantage of 855 can't be reflected. 855 is not too hot, so the performance will not be mentioned. At present, it is the strongest, but most machines do not have 5G baseband.

835 plus 5 passing by, still silky. I can't find a reason to change my mobile phone. I just can't play game cards. It's weird.

660 crane 835 845 855 refuses to argue?

There is also a god u Snapdragon 625.

835 is indeed the most balanced U among so many generations of U in Qualcomm. 8-series U has strong performance, but its power consumption has been unsatisfactory. It was not until the emergence of 835 that this situation was changed. In fact, I personally think that 7-series U is a better choice, with better power control and weaker performance.
