Public graphics card and mining

1.

The graphics card market in 2017 is the most special in recent years. In the past few years, no graphics card will increase its price by 100% a few months after its release. RX 580 has achieved this goal. Together with all the graphics cards below 3000 yuan, it has broken through the premium point in an irresistible manner. All this happened with the bitcoin price breaking through 3000 US dollars. After miners swept the RMB 2000 RX 580, the price of low-end RX 560 and even GTX 1050 Ti increased to varying degrees. However, is the price directly proportional to the ability of hash algorithm? Recently, we did a test to collect the new generation of graphics cards at various prices on the market, test the mining speed of Ethernet and bitcoin, and see which card has the highest cost performance

Different from the thousand yuan market, this wave of mining tide has a great impact on high-end graphics cards. In the test results, RX 580 and Rx 480 have almost reached the bottom of GTX 1070. Moreover, the price of Rx 580 is even competing with that of GTX 1070, so the miners directly swept the 3000 yuan market when GTX 1060 3gb / 6GB is out of stock, and GTX 1070 is basically out of stock. The more advanced GTX 1080 is also out of stock, but it's not clear whether the players are forced to go directly to the high-end card or the miners extend their claws to this market. The situation of GTX 1080 ti is only slightly improved, but it's not much better. However, not everyone can afford the 6000 yuan graphics card. Only the top players will be affected, but it's just a narrower choice. It's not the case that the rich can't buy it

summary:

to mine, the first choice is the graphics card with more than 3gb video memory, which is the basis. In addition, the core frequency will affect the mining speed. We have two GTX 1080 cards on hand, one is public version, and the other is MSI GTX 1080 gaming X. the operating frequencies of the two cards are 1885mhz and 1936mhz respectively. After testing, because of the frequency, the latter will be about 4% faster than the former in actual mining. The advantages of high-frequency graphics card are highlighted

So Xiaobian's opinions and suggestions are as follows:

the low-end card and the old architecture card are not suitable for mining. GTX 1080 ti is an extreme, with the most powerful performance, but the price is not suitable for large-scale procurement. The mining speed of a card with the same location is much faster than that of N card, The cost performance of GTX 1060 3gb is higher than that of GTX 1060 6GB. The frequency and the number of stream processors / CUDA have a great influence on the performance of the card. The size of video memory has no influence on the mining. It's enough. Different video cards will have different profits if they dig different coins. If you want to further explore, you need to test several currencies, Limited to space, we only select two representative currencies to test

as long as the mine disaster does not occur, the shortage will last for a long time. However, if there is a mine disaster, a large number of second-hand mine cards will directly enter the market. These cards are always running at full load and full speed, and their service life is greatly shortened compared with that of ordinary users. Even if the price is lower, they will roll over at any time, There is no need to start at all. Moreover, the second-hand market will be directly disrupted. At that time, it will be difficult for some normal users to get out of the second-hand market, and the deep-water fish's Dragon killing knife will explode the galaxy. Now it is said that NVIDIA is making some graphics cards without display output interface, which are provided to miners as mine cards. With a certain capacity, if the mine card still can't satisfy the miners, won't the miners buy the graphics card in the consumer market? The only function of these special mine cards is to prevent mine cards from flowing into the second-hand market, which can not alleviate the current shortage of graphics cards

2. The main problem is the life span

assume the same good environment

a 24-hour full load / high temperature operation

one is standby or not running
then the life of mine card is much lower than that of normal graphics card.

3. You can install three graphics cards with PCI-E adapter. You can read the tutorial online. The cheapest graphics card is 7770, and the speed of a single card is 200. If you make three graphics cards, the average monthly income is about 1000-1200, because you don't need to pay for electricity, so this part is not excluded for you

4. Today's bitcoin mining uses amd graphics cards, which are not very different from ordinary graphics cards. You can also play 3D games on them for design. The most popular one is the hd7850 1g version, which can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.

6. The heat dissipation of MSI 290x gaming is the best in the instry. At present, mining also ranks first in the single card. The non-public version of the card is even better in terms of material and performance. Compared with the public version, the power supply scale is also very moving. Buy it. The quotation of Jingdong is now 4999. Let's be friends.

7. Mine card refers to the graphics card used for mining (bitcoin). Mine card used to have a special (Computing) graphics card, but now mining is so hot that ordinary graphics cards are used for mining
public version refers to the graphics card officially issued by NVIDIA or AMD after the release of the new graphics card GPU. Generally, it only has basic graphics card functions and is not cost-effective

8. As like as two peas, Luna is basically the same. 1v1, lost temple (formerly China's national library, now common on Haofang platform) Luna (now vs platform is basically playing this picture, if you don't know vs platform, I will introce: this platform level is calculated according to the win-win relationship, the overall level above is higher than Haofang platform, and there are many domestic experts playing on it. So now we can basically judge his level from the level of vs. www.vsa.com.cn Python,Longinus,Peaks_ of_ Baek,Reverse Temple,R-point,Rush_ Hour, etc. (other interesting pictures for Korean professional league matches, not common) 2v2, hunters, big game hunters, lost temple and Luna sometimes see people. 2v2 map features: Lost Temple: there are intersections in the main mine, highland people can seal it; The mine has high ground, which can be disturbed by airdrop. Standard Terran map Luna: the main mine has intersection, the Terran can't seal; There is no high ground for ore separation; No building in the middle of the map. This paper mainly introces the common maps, including: lt, Luna, nostalgia, R point, rush hour, ROV, incubus, blade storm, forte, sattarchasm, Chow Chow, azalea, Gaia, paranoid, Android and other common maps, Generally speaking, a small number of crystals is not suitable for a single mine. Forte is a map with many crystals. The main mine can be mined for a long time, and even if there is no ore division, it can be used to storm troops for a long time, Keep suppressing the other side * * the number of fractional crystals corresponds to the number of main mines. There are six (forte, blade storm), seven (r-point) and eight (LT, Luna). The reason is very clear. The more fractional crystals, the greater the economic help of mining. Pay attention to the number of barracks added after mining * * the size of main mining area, which has an absolute impact on t, If the main mine is small, it's hard for man and God to hide their tactics. When the population reaches 50, there is no place to build a population. It must be expanded. As we all know, the expansion is the most vulnerable, and there are many attack points. However, this has no effect on Z. no matter how small the main mine is, it can build three bases, and it can continue to storm troops, However, the Zerg's racial factors determine that Zerg is a race that wastes resources and is forced to expand. The Zerg of single mine is not powerful. Please note that the supply of Zerg is flying in the air, which is an advantage most of the time, Of course, there are also disadvantages (terrible pirates and hidden flying). Please note that the distance between the main mine and the sub mine is mainly for the expansion of Zerg, because when the Zerg is opened in the early stage by rush, you often need to pull the farmer and the dog to help. When opening the mine, you must take this distance into account. For example, Gaia is far away, Luna's 1:00 and 5:00 are also far away, but 7:00 and 11:00 are very close. This is because the intersection can only be opened downward, and there will be supplement at the back. Too far distance is also a problem for anti airdrop in the middle and later period. Mobilizing the main forces back and forth for mutual defense will lead to a serious shortage of positive forces and a great loss, It's easy to defend, on the contrary, it's easy to be attacked by the air force (especially the flying dragon). This is the main reason why the flying dragon is very powerful in Luna, and the flying dragon is almost useless in rush hour and Gaia (except for the point where the distance is close in the air), Because it can attack and harass with flying dragon and big flying dragon, Zerg himself is not harassed by the air force, and he is good at PVT, and can't stand tank on the sea. It can greatly relieve the defensive pressure of Protoss. Luna is the most typical representative of this feature, except that the five points are facing inward (another intersection can only be opened downward) ~ ~ if it's land outside, it's definitely good for t, It's basically the paradise of tank, and of course it's also the happy land of lurker, dragon, HT and cannon. It's also necessary to distinguish whether the land outside is highland or flat land. If it's Highland (LT, sattarchasm), it must be airdropped to be effective. In this way, the Terran's fast technology airdrop tank and the mid Zerg's lurker airdrop are good, while P can only drop a little dragon, HT or building cannon. Dragon is too small to kill farmers, and HT has no sustainability. With the help of vision, tank and sunken can easily prevent it, while P can only transport troops to relieve the crisis. Expensive and slow Protoss transport planes are the best tools at this time, poor Protoss; P> Z. If it's flat outside, it's easy to be attacked by the main forces, especially t's large forces. Tank can usually blow up the mines. However, Z, P's troops can only use lurker, dragon and HT to harass, which is not enough to cause a devastating blow to the mine division. If there is no effective counter attack means when Terran advances here, then the result is the mine division reimbursement, which is a crisis of form** Nostalgia is the most influential factor in the division of mines. Bifrost and blade storm are also alternative non gas divisions. The most obvious feature of this kind of map is that it is dominated by primary arms, and only half of the usual gas should take into account the combination of science and technology and intermediate arms, PS: I found that this map PVZ can make up for several Reavers after opening 2 mines according to the characteristics of the opponent's more dogs. It has a wonderful effect on both attack and defense, Forte is 16:2. After a period of time, you will find that you don't have enough money on BS, but enough gas on forte. You can control the number of barracks and scientific and technological arms according to this feature, In fact, this is similar to the normal Xiaopo Datong Xiaoyi, but we need to pay attention to two points: one is that we must have a vision; the other is the terrain and formation of the big troops when they exchange fire here, For VT, you should pay attention to tank rush, airplane rush, highland tank (if there is highland), fast airdrop mm and leaky firemen. For VP, you should pay attention to Reaver + dragon single mine, slip DT, airdrop DT or Reaver, highland dragon or cannon (if there is highland), At the same time, we should try our best to promote science and technology. If we have high ground, we should consider Feilong; P > T, after discussion, it seems to be T & gt; P > Z. I don't have the doctrine myself. I'd like to leave a blank. Let's talk about it later... * * whether the three mines are easy to open or not, and whether they are together or not. The most obvious thing is Azalea. The three mines are easy to open, so we must try our best to make up more barracks and bases. In the case of a good economic crisis, it will show that gas is seriously insufficient. We should pay attention to building more first-class soldiers, In fact, the three mines of R point are easy to open, because there are mines on both sides. You can choose your own side according to the position of the enemy. Generally speaking, it is easy to defend and difficult to attack, This is no doubt beneficial to the first expansion of the race (Zerg), and PVT is still balanced, after all, the high resource Terran of the four mines will soon be 200; P > Z. a map with many mines is a paradise for stealing mines; A large part of the battle at p * * intersection takes place at the intersection. Experts all know how to use the advantages and disadvantages of the intersection. The intersection is mainly slope, but we should pay attention to the lowlands and highlands. Generally speaking, the main mine side is standing on the highlands (LT, Luna). The most important factor for the attacker is the vision. I think everyone has a deep understanding of LT intersection, I won't go into details. We should also pay attention to the map of lowland intersection (Requiem). TVP must start with seige tank to fight against dragon suppression. The nightmare of the majority of Terran users starts. TVP of low level intersection (azalea, inubus) also has the problem of dragon suppression. Moreover, the level intersection is larger than the ordinary intersection, so it is difficult to block the intersection in PVZ. Please be careful to avoid the harassment of speed dogs, TvZ is also easy to be harassed by dogs. I hope you'll pay attention to it. These so-called high and low-lying intersections have no impact on Zerg's defense, because Zerg usually defends on the ground after leaving the sub base, so there's nothing to worry about. In fact, even the intersection is different. Forte's intersection is smaller than LT, and a good zealot station can block the dog (you usually use two), Luna's mouth is bigger than lt's, and the two well positioned zealot can block it (we usually use three), but 815 is not mentioned. * * * the crossroads at the crossroads are good for guerrillas and sneak attacks. The crossroads are good for ZVT, zvp and PVT, and they are a paradise for high-speed arms. Tank rush is basically ineffective for this terrain (dogs can sneak out), When large troops go out to attack, they should pay attention to being attacked by rings or DT; P > Z, the closer it is, the easier it is to rush and push. Most people tend to suppress it forcefully in the front, and it is difficult to open a mine, but it is difficult to push in the back; P > T. It is generally inclined to start with science and technology, mining is easy, and advancing is difficult and slow. Requiem is a famous near point map, and lt also has this characteristic. In other arkness, Gaia is far away. Conventional maps Luna and nostalgia also have the difference between far point and near point, Technology based harassment, suppression and mining is the main way to start. It's basically the world of airdrop arms and flying dragons. Airdrop and anti airdrop are the essence of this kind of map. Please compare lt's 69 point and Gaia's near point, but don't use the shameless air propulsion tactics of the Terran, This tactic is generally invalid in other maps * * whether buildings can be built in the middle of the map is mainly used to limit the advance of TVP. We all know the difference between LT positional warfare and Luna's tank horizontal thrust * * if there are obstacles in the middle of the map, T & gt; P > As you can see from the example of Z and lt, we can say that the temple in the middle is designed for T. The more obstacles there are, the more favorable it is for high range arms, and the greater the racial disadvantage it is for the need of clipping. * * in the open middle zone, buildings (forte, ROV) can't be built in the middle, which is concive to highly exciting arms, such as TvZ's SK, Zerg's Dog + lurker's clipping, PVT forces the tank array, while obscene tank positional warfare is not suitable when the number of tanks is not enough

9. I just say that China is playing all over the world
1v1 is Luna

2v2 is big game hunters and hunters

although there are dozens of online versions of Luna
there is little difference
in the final two versions, the difference is
the width of the bridge.. Some versions of the final version are wide bridge
some versions of the final version are thin bridge
I think wide bridge is fairer

thin bridge is always poor in fighting, especially t bridge, where it is difficult to score Z and P from the bridge randomly

if you change the wide bridge, it will be easier to attack
