Mining machine Panda
Bitmine is real
bitcoin is proced by mining. Every 10 minutes, the miners of the whole network work out an arithmetic problem together. Whoever works out the answer first is equivalent to digging into this block, and the miner can get the bitcoin reward of system rebirth
after bitcoin is g in the mine, the income is distributed according to the proportion of the mine's computing power, so as to ensure a more stable input-output
every other time point, bitcoin system will generate a random code on the system node. All computers in the Internet can search for this code. Whoever finds this code will generate a block and then get a bitcoin. This process is often called mining. Computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin profits more quickly, which is also an important reason for the recent shortage of graphics cards
Bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners
advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to
the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)
people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)
I hope I can help you
I recommend two: ant G2 graphics card miner, panda B3 plus graphics card miner
ant G2 graphics card miner is used to mark panda's B3 plus graphics card miner. In terms of computing power, they are almost the same. On the one hand, they use the vest card, and on the other hand, they use the rx470 without the vest, both at 220mh / s
on September 25, Zhang Jianfeng, chief technology officer of Alibaba group and President of Alibaba cloud intelligence, announced that pingtouge released the world's highest performance AI reasoning chip, Hanguang 800 Hanguang 800 is Alibaba's first self-developed chip, which is said to be the most powerful AI chip in the world. It is mainly used for cloud vision processing scenes strong>
what actually leads to such a high budget for special effects? Usually, the cost of special effects proction is divided into three aspects, including hardware, software and manpower
first of all, the expenditure on hardware usually accounts for about 20%, which is divided into modeling, animation, color matching, rendering, lighting, matting, etc. These are all materials that need to be replaced in advance after green screen matting. For example, the whole new York City in Avengers is modeled, And the whole vengeance team is shooting in the studio. So most of the time, the most time-consuming is not the shooting time, but the proction of these materials. There are only four shots in the film without special effects. You can imagine how much material is needed to proce
therefore, the drawing ability, storage ability and computing ability of the hardware all need very high configuration requirements, otherwise, the rendering time of a material is enough. So basically, professional servers or workstations will be used for rendering, and one or two workstations are useless. In most cases, thousands of workstations and servers will be built to compress the rendering time
is there a hint of miner ~
for example, foreign special effects leaders: Instrial shadow and digital kingdom will specially build such rendering bases, so normally, the hardware part of the special effects proction foundation can't be satisfied without tens of millions of dollars
it's better to understand the software. For special effects, you need to install all kinds of righted software, such as Maya, nuke, mocha and other professional software. These software are generally packaged every year. A computer costs more than 1000 dollars a year, and it's a big expense to install each one. Sometimes we need to develop our own plug-ins to meet the needs, such as many machine learning technologies to transform character modeling, or some special renderers
but the biggest expense is the cost of human resources. Usually, the special effects team of a special effects blockbuster is about a thousand people, and it doesn't include some outsourcing projects. A team like this has to spend more than $60 million a year on its basic salary, and it usually takes about two years to proce, Like "Avatar II" this pigeon for several years, perhaps the cost of labor alone are hundreds of millions of start
and the salaries of top special effects engineers are generally high. That's because it's very difficult to do special effects. You usually need to learn more than a dozen software operations, and most of them are plug-in templates or tutorials in English. There are few opportunities to learn in China, so it's still difficult to proce some excellent special effects engineers.
