How to see the mining power of graphics card
eth is only 32mh / s, 1070 has 40mh / s. Many people say that 1080ti can't pull up the computing power because of the high delay of gddr5x video memory. As expected, it's better to mine with a card. People on the Internet say that 480 can have 65mh / S computing power
Zec, 724sol / s, nearly three 1060 3G, the total price is more expensive than three 1060 2K soft coins. However, compared with the short supply a-card rx4808g, the price of three cards is less than 5K, and the computing power is 900 + sol / s, but it's useless if there is a price but no market
it's too wasteful to use this card for mining. It's just for fun and can't afford to hurt.
a card. To put it bluntly, it depends on the frequency and SP

the better the a card, the stronger the mining.
Graphics card mining is a process of increasing the bitcoin money supply
the reason why the graphics card is used is that mining is actually a competition of performance and equipment. The mining machine is composed of graphics card array. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
computers have professional mining chips, and most of them work by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin
extended data
bitcoin does not rely on the issuance of specific monetary institutions, and is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
the bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (the blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times
when a node finds the solution matching the requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block
The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware
the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient

Mini excavators with the weight of less than 6 tons, small excavators with the weight of 6-15 tons, medium excavators with the weight of 15-30 tons, large excavators with the weight of 30-150 tons, and super large excavators with the weight of more than 150 tons. Sany Heavy Instry has more than 200 tons of super large hydraulic excavator
the three most important parameters of excavator are operating weight (mass), engine power and bucket capacity. Common excavator structures include power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The transmission mechanism transmits the power of the engine to the hydraulic motor, hydraulic cylinder and other executive elements through the hydraulic pump, and promotes the action of the working device, so as to complete various operations
the materials excavated by excavators are mainly soil, coal, silt and soil and rock after pre loosening. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction
extended data
there are two common excavator driving modes: internal combustion engine driven excavator and electric drive excavator. Among them, electric excavator is mainly used in plateau hypoxia and underground mine and some other flammable and explosive places
according to the different scale, excavators can be divided into large excavators, medium excavators and small excavators
according to the different walking modes, excavators can be divided into Crawler excavators and wheel excavators
According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines According to the use, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators and other different categories According to the bucket, excavators can be divided into forward excavator, backhoe excavator, dragline excavator and grab excavator. The front shovel excavator is mostly used to excavate the materials above the surface, and the backhoe excavator is mostly used to excavate the materials below the surfacevirtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum" is popular in the circle
network virtual currency can be roughly divided into
[1] the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
[2] the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
[3] the third kind of virtual currency on the Internet, such as bitcoin (BTC), lightmoney (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency
[4] the application of computer communication technology and the development of Internet as a new media are the technical basis of network marketing. Internet was born in the 1960s. With the development of network protocols and related hardware and software procts, Internet has graally changed from military to commercial and civil. From the 1990s, the Internet has graally entered into the daily life of society. As a matter of fact, the Internet, as an emerging media, has developed faster than all other technologies in the past. It took 38 years for radio to reach 50 million audiences, 13 years for television, and only 3-4 years for Internet. Therefore, the Internet is considered to be the technological change that has the greatest impact on the world economy in the past 100 years
