The average calculation force of L3 is 400
In fact, the coins that can be g up every day are different. When L3 + first came out, it was able to dig one Wright coin every day. Now the computing power of the whole network has been greatly improved, and about 0.54 yuan can be g every day. It mainly depends on the comparison between your computing power and that of the whole network
For example, when many enterprises choose servers, they will consider the difference between blockchain servers and traditional servers? The following is a brief analysis
to be exact, the blockchain is a technical model, and the server is a type of hardware resource. There is no contrast between the two. However, if we insist on the difference, we can also see the difference and connection between the two
to say the difference between the two,
the biggest feature of blockchain is decentralization, such as bitcoin, the most typical application of blockchain. Bitcoin is independent of any third party's decentralized currency. There is no centralized issuer. It is generated by the calculation of network nodes. Anyone can run bitcoin client software on the computer to participate in the proction of bitcoin. No matter where they are, anyone can dig, buy and sell bitcoin
all nodes of the blockchain are distributed in different places, and each node is maintained and managed by itself. It does not need centralized construction, but also needs special management and maintenance, which can make full use of idle resources. Due to the distributed characteristics, the system is difficult to destroy, such as bitcoin. Even the most powerful people or organizations in the world can't destroy the bitcoin system based on blockchain
traditional server is centralization service
traditional centralization server, such as WeChat, Alipay and so on, are all responsible for providing services to all clients by the server behind the company, and the client acquires services from the server. If their servers are attacked and paralyzed, then your WeChat and Alipay will not be able to use them. For example, on May 28, 2015, Ctrip was attacked by unknown server, and its web version and mobile app could not be used normally
does the blockchain still need servers
to be specific, blockchain is also divided into public chain, private chain and alliance chain. The essential difference between the three is that they have different degrees of decentralization
that is, the public chain is completely decentralized. The above mentioned bitcoin belongs to the public chain. The private chain and alliance chain are not completely decentralized, and there is still a shadow of centralization
as mentioned above, blockchain is a technical model, and server is a type of hardware resource. The two will inevitably have a combination of applications
for example, the combination of storage type server and blockchain can use cryptography to ensure the security of data transmission and access, so as to make the storage server data more secure

On January 7, Qualcomm officially released its new autopilot computing platform, snapdragonride. The platform includes security system level chip, security accelerator and autopilot software stack, which can meet the computing requirements of the highest L4 / L5 autopilot. Qualcomm announced that the platform will be delivered to automobile manufacturers and first tier suppliers for preliminary development in the first half of 2020, and the vehicles carrying the platform are expected to be put into mass proction in 2023
interpretation: as early as 2012, Qualcomm entered the automotive chip field. Up to now, the cumulative amount of orders from Qualcomm in the automotive sector has reached $7 billion, up from $6.5 billion two months ago
however, the previous chips were all communication and entertainment chips. At the press conference, Qualcomm disclosed that it has been more than four years since it launched the autopilot chip. In 2017, Qualcomm obtained the license of automatic driving test in California. The purpose of this test is to verify its chip
currently, one of the biggest pain points of autopilot chips is that it is difficult to achieve the balance between computing power and power consumption. From the beginning, Qualcomm decided to make use of its accumulation in the mobile phone chip instry to make high computing power and low power ASIC chips. Snapdragonride, the L4 level automatic driving computing platform released by Qualcomm, is equipped with two self-developed automatic driving processors ml (ASIC), GPU and CPU
snapdragonride platform can achieve the highest computing power of 700tops with 130W power consumption. If this plan can be realized, then Qualcomm's automatic driving scheme is quite competitive in terms of computing power. For example, compared with the 144tops / 72W of Tesla hardware3.0, the energy efficiency advantage of Qualcomm's procts is obvious
among the mass proction schemes, Huawei's mdc600 has the strongest computing power, with 352tops computing power and 352w power consumption; Next is NVIDIA's drivepegasus, with 320tops computing power and 500W power consumption
according to the plan, the computing power of agxorin, the computing platform of Orin based on the next autopilot chip, can reach 2000tops, but the power consumption can also reach 750W, which can hardly be applied to mass proction vehicles
in contrast, Qualcomm's autopilot computing platform does not need a fan or liquid cooling system, but uses a simpler passive air cooling system to achieve higher reliability
snapdragonride platform also reces the number of chips and turns them into L2-L3 automatic driving solutions with computing power of 60-120tops or ADAS solutions with computing power of 30tops. At this CES, Qualcomm and GM reached a cooperation on ADAS business
in terms of business model, Qualcomm's approach is relatively open. It can provide full stack solutions, or only sell chips, algorithms and sensor solutions, which can be handled by customers themselves
in the future, v2x chip will also be one of the important revenue sources of Qualcomm in the automotive business
in addition, through its car to cloudservice, Qualcomm also provides technical support for car companies in cloud computing and Ota. It is worth mentioning that its car to cloudsoftsku supports the security upgrade of chipsets

computing power: in short, it is a quantitative indicator of the computing speed of your mining machine. For example, 1t computing power is the 12th power of 10 in 1s. If the 12th power of this 10 can work out the results that meet the conditions, it will be g. If not, it can be said that it is in vain
in the face of the exponential increase of data, computing power is the biggest demand for enterprises and institutions, and improving computing power requires higher performance CPU and GPU
last time, AMD processor pushed the computing power of HPC to billion times, but now AMD with epyc processor pushes the computing power of supercomputing to 10 billion times again. AMD's two E-class supercomputer systems, frontier and El Capitan, are scheled to be delivered in 2021 and 2023, respectively. They will achieve the expected processing performance of more than 150 exaflops (10 billion times) and 2 exaflops, respectively, and are expected to become the fastest supercomputer in the world
it is a big challenge for any manufacturer to improve the computing power in a short time. How did amd make such great progress? Let's start in 2017
in 2017, amd adopted a new Zen architecture, launched the first generation epyc processor, and dramatically increased the number of single processor cores to 32 cores. Two years later, the introction of the second generation epyc processor not only upgraded the architecture to zen2, but also reced the process technology from 14nm to 7Nm, which improved the IPC performance by 15%
compared with the Zen architecture, the new zen2 architecture optimizes the L1 instruction cache, doubles the operation cache capacity and floating point unit data bit width, and doubles the L3 cache to 16MB. The 64 core epyc processor easily has 128MB L3 cache. What's more, the second generation epyc adopts 7Nm process, which effectively reces the power consumption. Under 225W TDP, the number of cores can be increased to 64 cores, which makes its performance significantly improved
in the past year, the second generation of AMD epyc processor has achieved more than 140 world records, covering cloud computing, virtualization, high-performance computing, big data analysis and other fields, and also with strong performance to meet the increasing demand of enterprises or institutions for computing power
therefore, relying on the leading performance of epyc processor and ultra-high power consumption ratio, amd has not only won more market share and broken many world records, but also expanded its ecosystem.
personally feels that the design is very scientific and technology. At the same time, the system can remember the commonly used parking spaces of car owners and realize the automatic parking of the last kilometre. In addition, Xiaopeng automobile also said that according to the maturity of the instry technology, the future procts will upgrade the L4 level automatic driving system. This makes many people full of expectations, and the new car Xiaopeng P7 will be equipped with high safety digital car keys for the first time, and support Bluetooth and wireless network connection. It can switch lock, start vehicle, share key and remote control vehicle. The identity card technology of the digital car key is developed by Xiaopeng automobile and Alipay. The security level is high. It is a financial level standard. p>
