What is the concept of the world's top 500 enterprises? If an enterprise develops into the world's top 500, it must be in a leading position in the instry. From a certain level, it can represent the overall development level and trend of the instry

a strong indivial is not strong, only a strong country is really strong, we need to work together to help China's economic development. We need to innovate constantly, cultivate innovative ideas in our hearts, stimulate innovative thinking, and make innovation a kind of consciousness. Only by continuous innovation can we survive in the fierce competition. Talents from all walks of life in China need to constantly work hard and learn, create value in the struggle, and help enterprises and the country to a higher peak

China's Internet giants are obviously entering all levels of business iteration in an omnipresent, omnipotent and fearless manner. The latest news is that Tencent and BMW will jointly establish a computing center in China to jointly develop and drive autopilot.

with the frequency of driver takeover as the evaluation standard, waymo of Google's parent company alpha ranks first and is far ahead, cruise of General Motors follows, and Internet companies occupy the seventh place. Two well-known companies were unexpectedly at the bottom of the test, with Uber at the bottom and apple at the bottom

waymo, who has the best performance, only needs to take over once for every 17846.8km, while Uber, who is the last to last, has only 0.6km. That is to say, there is a problem with the distance of one stop of the bus on the road. The apple, second from the bottom, can only support 1.8 kilometers on average. These two companies are purely involved in the field of automatic driving with the attitude of making soy sauce. There is a reason for their poor performance

Today, more and more manufacturers have installed auxiliary driving system on their models. For example, Cadillac's super cruise system, Subaru's EyeSight, Volvo's city safety system, and even the automatic driving system on Audi A8. From the perspective of technical difficulty and function implementation, , there is no essential difference between them and Tesla's autopilot. Strangely enough, when it comes to autopilot, the first thing most people think of is Tesla and its autopilot

among them, processing the image data from the camera consumes the most computing power. The latest autopilot driving system is equipped on the latest model 3 of Tesla, and the hardware is equipped with al independent power supply to supply power for two FSD chips respectively. In this way, when one of the power supply is damaged, one of the FSD chips can work normally to ensure the safe driving of the vehicle< br />

6. There is only a relatively reasonable model and a relatively reasonable price, and there is no absolutely excellent brand. "Brand only theory" is the taboo of buying a machine. "Love your house and your dog" is the best "consumer weakness" that manufacturers grasp. This applies to all electronic procts
take a few examples
[1] in a communication enterprise in Shenzhen, the communication instry can be said to be the world's leading, and its flagship mobile phone can also play well. The common people think that this brand is very powerful, and it's still a domestic benchmark to be touted as hope. But the people at the bottom didn't have so much money. He thought the flagship model of the factory was as good as the entry model, so he bought the entry model of the factory. However, this entry-level model of mobile phone has no type-C interface, 5GHz band WiFi is missing, does not support MU-MIMO, and the screen adopts 1280 × 720 resolution of the low configuration panel, flash grain is read and write speed is very general emmc5.1. As for the photography function that this factory is proud of, it is only limited to flagship models. These entry-level models are not qualified to carry flagship lens components
[2] at the beginning of its birth, a communications enterprise in Beijing, which widely used snapdragon SOC of Qualcomm, relied on its own excellent in-depth improved Android UI, small profits, quick turnover and hungry marketing, directly killed the traditional communication giants Nokia, Motorola and Starcom, and Samsung lost a lot of market share. Is the mobile phone of this company good? No worse than the Shenzhen factory above. Later, the factory began to do everything, including laptops and TVs. Some of their mobile phone users began to think, "the mobile phone is so good, others must be good.". In fact, on the contrary, compared with traditional manufacturers such as HP and MSI, the notebook of this company has a general configuration, poor heat dissipation and cutting die; Compared with Sony's medium and high-end TV models, it can only be said that the technology accumulation of the two factories is not in the same order of magnitude, and there is no comparability
however, after careful analysis, several batteries and chargers made by this factory are still very good
[3] in the early years, an old Taiwan motherboard factory was famous all over the world for its easy-to-use BIOS motherboard, high-quality materials and the first proct line for professional players. This factory is also regarded as the first echelon standard setter in the instry. When the word of mouth goes out, consumers begin to think that if this factory is so powerful in making motherboards, then graphics cards, routers and laptops must also be very powerful. However, like the target customers of Shenzhen factory mentioned at the beginning, ordinary consumers have little money and simply trust the brand. As a matter of course, these consumers fall into the trap of this Taiwan factory. It turns out that this Taiwan factory has no more than 20 motherboards worth buying at the present stage. The routers below 799 are very common. The graphics card is even more popular. The rtx2080ti, priced at 12000, is not as good as the 8000 + graphics card next door. As for the notebook? Worse than motherboard, no more than 10 models worth buying. In addition, one of the favorite words of the salesmen in the physical stores of this factory is that our motherboard is the first in the world in terms of shipment volume, and the notebook motherboard is also the best in quality
in fact, almost all electronic procts are inferior. It's not a good proct, it can only be said that it's set off by peers
go back to the main question

there are many kinds of computer needs for students, such as literature and history majors only need text editing, mechanical majors need 2D or even 3D drawing, biochemical majors need molecular configuration simulation which requires high CPU computing power, and media majors need media creation and rendering which relies on CPU and GPU computing power at the same time. It can be said that a thousand kinds of students have a thousand kinds of computer needs. Different needs have different requirements for performance. Do you know which kind of student you are? We need to know that some students' needs can not be met by the laptops of the above three factories, which can only be solved by desktop computers

therefore, it's better to clarify your own needs than to worry about the quality of your brand
if you have to get a result, it can only be said that Dell has no model with good enough proct strength in the past year, and it is not recommended by the whole system; Huawei focuses on light and thin procts. If you have performance requirements, don't look at them. If you don't have high performance requirements, please avoid all matebook D and don't go to Huawei's offline authorized stores to buy any Huawei computers; HP only needs to avoid pit cargo models, and most models such as battle 66 and shadow Genie can be considered.

Their differences are mainly reflected in:

1, performance difference:

the main difference between Hisilicon 9905g and Hisilicon 990 + Baron 5000 is that Hisilicon 9905g has strong performance

2, power consumption:

because of the use of plug-in baseband, the plug-in 5g chip has to redesign the circuit, which greatly increases the power consumption of his990 + Baron 5000. The problem of high power consumption is that the battery capacity must be increased, and the volume of the mobile phone will become larger

3, take up the internal space of the mobile phone:

because of the use of the external baseband, the space of the mobile phone occupied by the Hisilicon 990 5g is greatly increased compared with that of the Hisilicon 990 5g. The external 5g will undoubtedly change the original internal design of the mobile phone. The high power consumption and high heat of the 5g will inevitably affect the internal heat dissipation layout of each machine, and increase the heat dissipation design, including copper tube, liquid cooling and multi-layer heat dissipation design

{rrrrrrr}
