Introction
in 2012, amd re invited Jim Keller, who had worked in AMD for many years and led the design of Athlon 64 / Opteron 64 / HT bus / 64 bit instruction set, to take full charge of the design of AMD processor architecture, Develop a new kernel with high performance and low power consumption. This is Zen[ 2]
Zen is a very simple word, that is, Zen in Chinese Buddhism, which has a strong philosophical meaning and is very popular. Amd takes this as a code to emphasize the balance between different CPU design principles, and the result has been generally recognized, which can be said to have gone deep into the hearts of players [2]
in the final proct naming, amd also retained the Zen element, and got inspiration from NASA's new horizons Pluto mission [2], and finally named the new generation processor ryzen [2], implying the meaning of risen. Ryzen's Chinese name is Ruilong [2], which follows the naming method of AMD dragon series. The word "Rui" is not only close to ryzen's initial pronunciation, but also means to forge ahead[ 2]
Zen architecture
the news of Zen Architecture [2] has been coming out continuously since the beginning of 2015, and people are full of expectations: a new 14nm manufacturing process [2], a really new hardware architecture design, multi-core and synchronous multithreading support for the first time... [2]
amd Zen [4] is a CPU architecture completely redesigned from the bottom, with equal emphasis on performance and energy efficiency, The so-called IPC (instructions per clock cycle) [4] is more than 40% higher than the previous generation excavator [4], and the switching capacitor is also improved by more than 15% [4]< There are 16 pieces in total
improvement of Zen architecture
amd Zen [4] is manufactured by global foundries 14nm process, with a single CPU core area of about 7mm2 [4], and four cores only account for 44mm M2 [4]
Zen [4] has the third generation AVFs [4], which is divided into a large number of voltage control areas. For example, LDO (low dropout) voltage regulator [4] can be used to control the voltage (and frequency) of each CPU core, RDL (voltage distribution layer) [4], rvdd [4], VDD (core voltage control) [4], vddm (buffer voltage control) [4], and so on, At the same time, a large number of advanced frequency, voltage and temperature sensors are added[ 4]

3. There's nothing to dig out. AMD ryzen architecture is already excellent.
ryzen architecture designer Jim Keller is a big bull in the U.S. technology instry. He led amd K7 K8 architecture processor and beat Intel Pentium 4 processor at that time. After joining apple, he developed A4 and A5 processors, which created the foundation of Apple's own processor development. Later, he returned to AMD to develop the current Zen (ryzen) architecture, The performance of single core at the same frequency is no less than that of Intel Core Architecture, and the power control is better. After the design of Zen architecture, now he goes to Tesla.

4. Starting a business is not easy, and starting from scratch is even more difficult. In this case, you have to have a big advantage in other areas. For example, have a wide range of social relations, or have a certain financing capacity, business information and sales channels. In addition, not everyone is suitable for starting a business from scratch, but according to the actual situation of the indivial, there are many misunderstandings, and we should pay more attention to avoid them
analysis: are you suitable for starting from scratch
for self-made entrepreneurs, the methods and skills are different, but the requirements for ability and quality are usually the same< Chen meizheng graated from university and worked as a salesman in an advertising company in Wuhan. Once, the company sent several male salesmen to a company to talk about an advertisement of 80000 yuan, all of which came back empty handed. After Chen meizheng took over, he first investigated the interpersonal relationship of the chairman of the company. She learned that Wan Ling, a classmate of her university, was the niece of the chairman, so she invited Wan Ling to lead the way to help. Because of her beauty and eloquence, she soon won the business after some negotiation. A year and a half later, Chen meizheng founded an advertising company. Although she didn't have much money at that time, she made good use of her advantages. Coupled with her extensive relationship as a salesman, her company soon had little influence<
strategic analysis: because of lack of financial strength, it is difficult for self-made entrepreneurs to recruit or afford high-level talents, and they do not have much money for advertising or marketing. Therefore, most of the business sources at the beginning of entrepreneurship depend on social relations. Even for those who start from scratch without social relations, the first thing to do when starting a business is to establish a wide range of social relations, so that more people are willing to help you< 2. Wise foresight
Wang Juan, who was laid off from the clothing factory, is a smart and fashionable person. Seeing DIY leisure and entertainment in the city, she thinks that if we open a DIY shoe bar under the trend of DIY, there must be a market. A pair of ordinary shoes, after her careful "dress up", there are surprising details. Fluff, fluorescent band, plastic star, moon... Will become the decoration of shoes. Attracted by Wang Juan's various creative ideas, her DIY shoe bar is often filled with young people who like novelty. Six months later, with her keen judgment, Wang Juan created a new world of wealth<
Strategy Analysis: for self-made entrepreneurs, if they want to succeed, they need to seek a good project or proct. At this time, three points should be considered: first, the proct or project should conform to the trend of social development; Second, the proct or project should be different; Third, when promoting the proct or project, it does not need or only needs little start-up funds. This requires entrepreneurs to grasp the future development and changing trend of the market, so as to find and occupy a place< Good reputation and moral character
as the person in charge of the glass procts company, Chen Yadong can't have today's brilliant career without honesty. When he started his business, his factory was still a small workshop, and he could not afford to pay high wages to recruit suitable talents. But he treats his employees with integrity. After several years of hard work, his reputation has been greatly improved, and many technical talents and other small workshops are willing to join him
Strategy Analysis: entrepreneurs who start from scratch will not have high business reputation because of their small scale of operation. At this time, it is necessary to use the entrepreneur's personal reputation and character to guarantee, only in this way, others will be willing and dare to cooperate with you. After people believe in you, they may believe in your business and procts<
4. Hardworking spirit
when Zhu Xiaoguang was working in a flower shop in the provincial capital, he accidentally broke a pot of wild orchid grass. He took out 10 yuan compensation, the result of the boss said at least 50 yuan. Zhu Xiaoguang is mbfounded, because this flower is everywhere in his hometown. So he took time to go home and dig some sacks of wild orchid grass, which sold well. So he quit his job and went it alone. It's a long way to dig wild orchid grass from my hometown and transport it to the provincial capital. But Zhu Xiaoguang went back and forth between the provincial capital and his hometown, and started a business without capital. In less than a year, he made several times more money than when he was working<
Strategy Analysis: compared with the rich competitors, the self-made need to pay more efforts. Do more and offer more love. Your customers will be moved. This is the most powerful competition. People who start from scratch usually have to do everything by themselves, so they have to be prepared before starting a business. The market is snatched, not waiting
reminder: be careful to step into the wrong area
some people already have the ability and quality to start from scratch, as well as the corresponding methods and skills, but before putting them into action, they must understand and recognize some problems, and get out of the misunderstanding< The first mistake is that Liu Wei didn't succeed and didn't build anything.
after graating from university the year before last, he decided to start his own business without finding a satisfactory job. Because he had no savings on hand, he chose some jobs that didn't need to invest a lot of money and thought that even if he didn't succeed, he didn't get into anything. He has done proct sales, opened small restaurants, audio and video stores, and so on. In the end, it was because of his carelessness that he didn't do much and wasted his good time
reminder: most self-made people can't do without the support of relatives and friends. Failure will disappoint them and make them doubt your ability. More importantly, it will bring some unnecessary losses to your business partners. In this way, it will affect your business reputation in the future< Error 2: starting a business by himself, Mr. Wu has nothing to do after he is laid off, and he always wants to open a small shop. He found that the business of a pickle shop in the community was very prosperous, so he was eager to have a try. However, this is not only a big investment, but also takes into account procurement, processing, sales and other aspects. Later, he and his friends opened a chain store of "immortal chicken" by joining in. For this reason, Mr. Wu not only saved more than 10000 yuan of equipment costs for the proction of bittern, but also saved thousands of yuan of working capital
reminder: self made people need to seek support and cooperation more widely, and the best way is to start a business in partnership. A few like-minded people with their own strengths can complement each other and work together to make up for the lack of material conditions. There is also a relationship of benefit sharing with partners, who will start a business together wholeheartedly<
countermeasures: we should give you some help
we should decide whether to start a business or not according to our own actual situation. We can also find some ways to avoid detours. Here are two points< After Tao Qingyu, who lives in Shanghai, was laid off by his employer, he saw a small chain store in his residential area, and the business was very prosperous. Tao Qingyu thought: it's better to open a chain store by himself. But as soon as he inquired, it would cost at least 60000 or 70000 yuan to set up a chain store, so he had to give up. Later, Shanghai Pudong Development Bank signed a contract with Lianhua convenience, and launched a business of "investing 70000 yuan to be a small boss" for entrepreneurs. Since Lianhua convenience, as a partner, provides collective guarantee for entrepreneurs, Pudong Bank can provide 70000 yuan of entrepreneurial loans to applicants who have passed the qualification examination. Tao Qingyu submitted his application and set up his own chain store
reminder: sometimes, you find a good start-up project, but you need a certain amount of start-up capital. And you don't have that much money at the moment, but that doesn't necessarily mean you have to give up. In fact, you can use other people's funds directly or indirectly through your own wisdom and strategy. You can also use other business factors, such as business skills, technology and other intangible assets to exchange, replace or make up for the lack of funds<
2. Choose special procts or services
Li Wei, who graated from Horticulture Department of Agricultural University, is not happy working in a company with different majors. Later, he found that there is a kind of Flower Bonsai called "dancing grass" which has great prospects. This project has a large investment, but few people have been involved. As Li Wei is a horticultural student, he has great confidence in the investment of "dancing grass". He asked for help with the loan. Unexpectedly, in less than a year, he had a relatively rich income
reminder: people who have projects with less investment and quick results will enjoy them, which is hard to find. Even if you find it, others will follow. Before long, there will be many competitors around you. Therefore, those who start from scratch should seek special procts or services, also known as differentiated procts or services, so as to survive in the cracks of the market, which rarely attract strong competitors.

5. Most of the details of history were introced in detail by Li Miao. The following are mainly two supplementary comments, but they also involve many details, which may be cumbersome. My basic answer to this question is that, from the perspective of preserving the earliest tradition of Zen, Japanese Zen is generally better preserved. At present, the Han tradition advocates Zen and pure cultivation, but the specific reason is that it may be different from some details introced by Li Miao (especially in the later and modern times), and the actual relationship between Zen and pure cultivation will be more complicated today, Let's just ignore the trivial details that we're going to write about.
6.
At present, AM4 processor can be compatible with ryzen: amdryzen7, AMD ryzen 5, and the seventh generation APU of AM4 interface (such as a12-9800, a109700, etc., excavator Architecture)
amd desktop processor currently has AM3 +, FM2 +, AM1 three different interfaces, respectively for high-end CPU, mainstream APU, low-end APU, and from this year, they will all be unified into the new AM4
AM4 design
AM4 interface will adopt uopga style, which is slightly improved than the current upga, but it is still the traditional design with pins at the bottom of the processor and contacts on the motherboard. The specific number of pins is 1331, which is much more than AM3 + 942 and FM2 + 906
AM4 processor will continue to integrate a large number of extended function moles, among which the memory controller finally supports DDR4, with the starting frequency of 2400mhz, and can exceed the frequency up to 2933mhz
AMD ryzen
the core technology and molar architecture of K10 and bulldozer two generations of AMD high-end processors have long been marked with failure. This time, ryzen naturally wants to go back to the traditional SMT multi-core and multi thread architecture, redesign the kernel, and upgrade the cache system. At the same time, in terms of process technology, GF is no longer Wu xiaamung. Ryzen is upgraded from 32nm SOI and 28nm to 14nm finfetlpp, which is on the same level with Intel

8. The reason why AMD ryzen processor lags behind in the game is the optimization problem. Some tests mentioned that turning off the super threading (SMT) can improve the frame rate in some games, and the potential of new procts has not been fully exploited
the phenomenon that game performance is lower than that of competitors' procts is that game development and optimization are all aimed at Intel platform, at least for the moment. Even if there is no targeted optimization, in fact, ryzen processor has higher performance and smoother frame number than its competitors in all CPU bottleneck games and VR. As developers become more familiar with ryzen architecture and additional core and threads, we expect that performance testing will only be better, and ryzen will do better in the next generation of game experience.

9. This is not coal mining
10. First of all, there is doubt whether the proposal to increase the tax on the rich will pass. Now it is just a test of public opinion
secondly, there are many ways for the rich to avoid taxes, and investing money in virtual currency is only one of them. Moreover, there are great policy risks in this way. For example, India's recent announcement that trading bitcoin is illegal is a blow
in addition, the fluctuation of virtual currency is affected by many factors, which is the result of competition of many forces, such as US bond yield, US dollar index, gold price, etc.
