There are great differences between actual running and parameter
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
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
but the stronger the performance of the graphics card, the higher the efficiency
generally speaking, 7990 is the strongest, but it is also the most expensive, and the power consumption is also high
generally speaking, 7970 and 7950 are OK
Now there are more and more cars with 2.0T engines. Many intermediate cars already use 2.0T engines. But why are they the same as 2.0T engines< the results of 100 km acceleration of each vehicle are still quite different. In particular, the data of lacrosse, Mondeo and other American cars are so high , but the acceleration of 100km is not as fast as that of maiteng. Today we are going to talk about this topic
Finally, the maintenance quality of American cars is generally high, in other words, the lightweight of American cars is not as good as that of German cars. For a car, a rection of 100 kg is much better than an increase of 10 horsepower. Given the above, it's not surprising that American cars can't accelerate faster than German carsIn our opinion, torque should be a vague concept, which refers to the torque output from the crankshaft end point
engine torque is the force proced by crankshaft rotation, which is different from the straight forward force, so it needs to be expressed by the length of a rotating arm
like the "king of self-priming" car carried by Honda S2000 (parameter | picture), before 7000rpm, it is the same as a vegetable car, but after 7000rpm, if you step on the accelerator deeply, it is a sports car. This kind of engine is obviously inclined to high speed and high power. A smart gearbox and a disobedient gearbox are two kinds of driving experiences
