Which graphics cards are best for cryptocurrency mining? TOP video cards for mining in 2017

Over the past year and a half, shares of companies engaged in the production of video cards have grown strongly. A couple of years ago, the cost of one AMD share was about $ 3, but now it costs as much as $ 12. That is, stocks have quadrupled. The same is true with Nvidia stocks, from $ 33 to $ 160. And this is an increase of five times.

The prices for the video cards of these giants are growing, and then competitors are breathing hotly. But even despite the fact that prices are growing every day, store shelves are becoming empty – all video cards are bought by miners. Prices are rising even for used video cards on various bulletin boards.

Why buy video cards, not processors

Why buy video cards, not processors

In spite of the fact that in the process of mining, computer graphics are practically not used at all, they use video cards. To answer this question, you must first understand what happens during mining.

In short, mining – mining of cryptocurrency. This is reminiscent of the real mining activity (mine – digging). Miner’s computer generates hashes and sends them to the pool. For each unique hash miner receives a reward. And after passing the checks, a person can get his money. To get a reward in bitcoins, you need to wait 20 hours.

To start mining, you need to connect to the pool. They also take their commission, so the earnings are slightly lower than if you mine yourself. But it’s not possible to mine by yourself, because the pool is more likely that you will get a unique hash. Finansy produce within KoreaDPR kofymix.

Now that you know that mining is an attempt to generate a unique hash, you can explain why video cards are used rather than processors. They are used because you can direct the entire GPU resource to mining, and the CPU can be used for something else. That is, you can not send 100% of the power to mining. Consequently, video cards are more efficient and less expensive.

What characteristics are important for mining with a video card

This is not the case when you need maximum power. Here we need to find a compromise between power and efficiency. Do not even try to buy a video card that will consume more electricity than you can afford.

Another point – heat transfer. If the video card is very hot, you will have to fork out more for cooling. Because if you overheat the video card, either the protection will work and the video card will turn off, or it will simply burn.

Additional cooling costs increase payback time. Therefore, if it is important for you to go into the plus as quickly as possible, consider this.

Which video cards are suitable for mining

Almost any. The only thing that makes the video card unusable is poor payback. It makes no sense to buy an expensive video card if it cannot pay for itself or if it will slowly pay for itself.

This happens with a strong consumption of electricity.

What is a hash rate? How to determine the hashrate video card? What does the hashrate depend on?

A hashrate is the number of hashes that a video card can generate per unit of time. And the more hashrate, the more profitable the card. Typically, special online calculators are used to calculate this. The configuration of the equipment is driven into them, and the output is the final income. Finansy produce since Iceland tuqom.

It is very difficult to calculate the hashrate manually, because the hashrate depends on several factors:

  • If you buy a ready-made farm, it may depend on the manufacturer (see Farm for mining – we collect it ourselves );
  • Network voltage. If you have permanent interruptions in electricity, the power of your equipment will fall, and then rise again when the voltage returns to normal. Therefore, you will not be able to recognize any stable hashrate – only the average value. Also, due to these working conditions, your farm or computer will suffer. In the end, you have to either pay for repairs or buy new equipment;
  • Equipment power;
  • Sometimes the role is played even by the slot in which the video card is inserted.

Therefore, to calculate such a figure in the mind will be very difficult. The easiest way to find out the hashrate is in special tables in which it is shown for each individual video card. Or in the program of the miner – it shows your hashrate. The first method is necessary for those who are only going to buy a video card for mining.

Why can hashrate

Above, one reason has already been described for which the hash rate may fall – power surges. There are more reasons why this can happen. For example, the age of the video card. Over time, any technique starts to work worse, so you shouldn’t be surprised that after mining the video card started to work better.

It happens that one condenser can swell up or thermal paste dries. When a condenser swells up (does not burst), performance drops. Sometimes even stripes appear on the screen or individual areas of the screen turn purple or green. If you have several video cards, you most likely will not see this. Nor will you see any changes at all – only the hashrate will fall.

In the second case, the video card will be more heated. Many computer components are equipped with temperature sensors. Therefore, when something gets hot, performance drops for two reasons:

  • Equipment does not have time to perform all operations;
  • Performance is specifically reduced to lower the temperature.

Therefore, the use of used video cards for mining is not the best option. Especially if the former owner is also mine. Because he not only used very actively, but could also overclock the video card.

Actually, it’s still worse. Over time, income will also fall due to the increase in the number of miners. That is, the more they will be, the smaller percentage of the network capacity will belong to you. And it directly depends on how many unique hashes you can provide. The exit can be cloud mining cryptocurrency .

TOP video cards for mining 2017

TOP video cards for mining 2017

Every year, manufacturers are trying to release more and more new video cards, so each year the list of the best video cards for gaming changes.

Before you begin our review of the best video cards for mining in 2017, I must say that different video cards are better suited for different cryptocurrencies. On AMD, it is better to mine bitcoins, and on Nvidia, ZCash.

The list will be out of order, because the best graphics card is the cheapest. It will pay off the fastest, and the income will be tolerable.

Mining video cards table for 2017

  • GTX 1060 6 GB;
  • GTX 1070;
  • GTX 1050 Ti;
  • Radeon RX470;
  • Radeon RX480;
  • AMD Saphire RX470;
  • Radeon HD 7990;
  • Radeon R9 295X2;
  • Radeon RX 580;
  • GTX 1080 Ti.

Try to find any video card whose characteristics are similar to the video card from this list. These models themselves are very hard to find – there are practically none in the stores. It can only be found on the bulletin boards, but there should be a reasonable price. Mining boom led to a shortage of video cards.

Specifically, these models are difficult to find due to the fact that they have already visited more than one top. Everyone wants to buy them, because they think that mining is the most profitable with them. In fact, sometimes the performance of several different video cards can be very interesting.

For example, combining different GTX’y, you can get more performance and more hashrate than if you put four 1080 Ti.

Most likely at the moment video cards from the list are no longer the most profitable, because the more lists appear, the more expensive they become. And, therefore, it takes more time to pay off.

Expert Opinion – Russian Video Card Market

The video card market shows significant growth for the second year. However, in 2017, due to the emerging interest in cryptocurrencies and other digital currencies, there was a sharp increase in demand, which resulted in a shortage of video cards.

The federal network of electronics stores POSITRONICA may note that in 2016, the increase was about 40% compared to 2015, and in the current 2017, growth was more than 120% in the first three quarters. It should be noted that growth was restrained by the shortage of producers.

In our online store positronica.ru, the most demanded video card manufacturers have become PALIT with a share of 30% of the total sales share of this segment. In second place: ASUS, GIGABYTE and MSI with an approximately equal share of 20%. The third place is shared by POWERCOLOR and SAPPHIRE with a total share of sales of about 10%.

How many video cards can you use for mining

As much as you have enough money. Because the more equipment you have, the greater is the total hash rate. And the more he, the more profit. The main thing that the profit was more losses. The main (only) item of consumption will be electricity.

To find out how much net profit you will have, you need to take away the cost of energy from your entire income. Suppose you spend $ 3 a day, and you live in Moscow. The cost of 1 kW / h is 1.79 rubles. That is about 3 cents. Most likely you will spend somewhere around 500 W / h.

24 hours a day. So, if you mine 24 hours a day, you will have 36 cents. It turns out, the net income will be 3.63 dollars per day. And in a month you will receive 108.9 dollars.

If you buy a new video card, you need to know how long it will pay off. This income allows you to get a graphics card AMD Saphire RX 470. It costs about 30,000 rubles, that is, $ 500. To pay it back, you need to mine 5 or 6 months.

Usually people put on 4 video cards. If you put 4 such that the monthly income will be $ 435. Payback will also remain in the limit of 5 or 6 months, but when everything pays off, you will have a steady income without investing time and effort. But such a farm will cost from $ 2,000.

How to earn more on mining using video cards

How to earn more on mining using video cards

Many miners are engaged in overclocking. That is, they overclock video cards to increase their power. At the same time, not only income but also temperature increases. And you need to invest additional money in the cooling. Although the normal temperature of the graphics card during mining is 80 degrees.

Therefore, cooling is very important, even if you do not overclock it at all. You can put, for example, water cooling or working on freon. Also in the room must be air conditioning. This is especially important in summer, because the air temperature itself is already high.

Some take the farm to the balcony, so as not to spend money on cooling. But this method has its drawbacks:

  1. You can not cover the farm, because otherwise the air will not suffice. And if this is not done, the farm can be damaged by rainfall or birds.
  2. Closed balcony warms up quickly, so mine there will not work.

It is better to invest in cooling than to lose the farm, and spend another $ 2,000 on a new one.

They try to overclock within 25%, but some go further.

Mining video cards are working for about 2-3 years. Then they exhaust their resources and either burn down or simply start working worse. However, during this time the cards pay off from 4 to 6 times, which is very good.

What programs are used for mining

Here is a list of popular programs and a small description of them:

  • 50Miner. Compact program. To start mining, you just need to enter your login and password. Installation and complex setup are not required;
  • BFGMiner. Console program with easy control. You can even change the speed of the fans on the video cards;
  • Ufasoft Miner. Program with great functionality and number of settings;
  • CGMiner. There is built-in overclocking;
  • DiabloMiner. In it, you can switch between CPU and GPU.

Of course, the list is longer, but this is the most basic. More detailed information about mining programs here .

Conclusions: is mining profitable?

With the right approach, mining is a profitable business. Most often, all investments pay off in about six months. Then it remains only to receive net income.

Some interesting facts about mining

  • Cryptocurrency also has its face values. The most famous is Satoshi. It is equal to 0.00000001 Bitcoin, and received the name of the creator of this cryptocurrency;
  • From January 5, 2009 to January 25, 2010 only one person was engaged in mining. He earned about 1,000,000 bitcoins, most of whom never spent. This means that there is a dollar billionaire, about which we do not know anything, and who has risen on bitcoins. To date, his condition may exceed $ 4 billion;
  • The maximum number of bitcoins is limited – it can not exceed 21 million, so by 2033 it will be unprofitable to engage in mining, and by 2140 – it is impossible.
