Bitcoin mining performance test
however, you really regard mining as fun and entertainment. If you don't care much about whether you can dig, you can also let your own machine dig all the time. However, the machine configuration above you should not be low, but it is not suitable for mining, just as the swimming champion is not necessarily good at mountain climbing
generally speaking, mining machines mainly focus on graphics cards, which have little to do with processors, main memory boards and hard disks. Of course, they need to be stable and not crash for a long time. In fact, a card is more suitable for mining. In principle, you can go to the network. It is said that before the emergence of R-Series a card, the card with good mining effect was not hd88708750, But we despise the old graphics card that has been eliminated
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it
bitcoin is a kind of P2P digital currency
bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions
the biggest difference between bitcoin and other virtual currencies is that the total number of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
this virtual currency only needs the computing power of the computer, and it has no technical content. Basically, it only needs to hang up to "generate" bitcoin, and bitcoin can be traded at any time, so as to transform it into real currency
if you want to get bitcoin, you need to download the special "mining software" and set it to start
In general, the computing power of GPU is much higher than that of CPU, and even the entry-level graphics card is much better than the top i7 series. So it indirectly tests the performance of the graphics cardthe founder of bitcoin, Tsung Nakamoto, left the bitcoin project in 2010 and became one of the most mysterious figures in the coin circle. Bitcoin is made by mining. Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary.
mining machine needs top-level a card support
your n card can't do it
ATI 7950 can reach 300m
The price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, the high configuration bitcoin "mining machine" increased from 10000 yuan to 300000 yuan, but its performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013. Mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, the computing power after "grouping" can surpass the single graphics card of most users. And this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Taking into account the hardware price and other costs, there is a considerable expenditure in mining< br />
it is generally designed at 2.2-3.5km/h
if you really want to calculate, support the unilateral track
calculate the number of single circle gears of walking oil pump
calculate the speed of oil pump per minute = C
calculate the number of gun tubes in the track
measure the total circumference of the track = B (in meters)
formula: gun tubes divided by the number of gears = a
C except a times b times 60 = walking distance per hour
walking distance divided by 1000 is the speed per hour (1km / h = 1000m / h)
