Rating of video cards for mining: reviews and comparisons
A rapid surge in the popularity of Crypto-currencythe market provoked a great interest in video cards. From the shelves are literally swept away top and not only devices. But are they all suitable for mining crypto currency? In this article, the rating of video cards for mining will be considered.
Extraction of currency
The principle of mining work is to selecthashes of the target level of complexity. In the Bitcoin system, this level is recalculated every 2 weeks. It can increase or, conversely, decrease, depending on how far the creation time of hashes differs from a certain constant.
To find the values usedthe performance of processors and graphics cards. The more powerful the configuration, the faster the process. The reward can be obtained after 120 coincidences, that is, after about 20 hours. Thus, the reliability and stability of the crypto currency are guaranteed.
Today the methods of extraction are becoming popularcrypto-currencies using networks. The site owner or attackers can insert a special script into the code of their page that will use the resources of the computer of the user who came to the site. This has already seen several highly visited sites, and we must assume that this trend has the right to development.
Evolution of production platforms
The first time the mining was made at the expense ofcomputing power of ordinary processors. Then it was established that the technique of parallel computing is ideally suited for mining crypto-currency. And with this, the graphics processors performed great. And Mining switched to video cards. Since the complexity of algorithms has increased over time, the use of CPUs has come to naught.
With the advent of special architectural solutions -ASIC, the speed of mining has increased significantly. Since that time, the production of crypto currency even on productive video cards has become unprofitable because of the cost of electricity. However, many still implement whole farms, consisting of only video cards.
Rating of video cards for mining
In the world of graphics adapters, leadership is heldtwo manufacturers - AMD and Nvidia. Before choosing a video card, the miners evaluate not only the general parameters - the amount of RAM, the frequency of the processor, but also the hashtate - the processing power. It shows how many hash values the system can handle per second. Equally important parameter is the energy efficiency of the card. It shows how cost-effective it will be to use it. The final result, which should be oriented in the rating of video cards for mining, is profitability. It is worthwhile to consider interesting specimens, to which the "miners" pay special attention.
Gigabyte Radeon R9 Fury X
Probably, one of the most powerful video cards forMining out of the rating. The graphics processor is developed by AMD. Its capacity is estimated at 27Mh / s. The peculiarities of the model are that the cooling is structurally divided, which makes it possible to seamlessly integrate several cards into one system. However, this gadget is made using 28 nm technology. And this is a strong blow to energy efficiency and, as a result, to an extended period of time to payback.
Sapphire Nitro OC Radeon RX 470
470th model is popular in the rating of video cards formining Ethereum. The hashedrate is 24 Mh / s. In this case, this adapter, in fact, like all the others from AMD, can be overclocked by 30-40%. Specifically, this model consumes only 120 watts, which means that the card can pay off much faster.
Sapphire Nitro OC Radeon RX 480
This card in the video card performance ratingfor mining by right can be called the best among AMD products. It is made using 14 nm technology. However, while its power consumption is quite high - 170 watts. Has a large number of universal processors, giving good performance in general.
MSI Geforce GTX 1060
This card is ideal for using it in video games. However, for mining, this is a controversial decision. Its value is slightly lower than its counterparts and its closest competitors. At the same time, both maintenance and electricity costs are much lower, because the consumption is only 120 watts. Though it's not so profitable to get it, but in the rating of video cards for mining Zcash shows good values - 310 Sol.
Gigabyte Geforce GTX 1070
The video card has a performance of 27 Mh / sand 440 Sol. High frequencies of the processor and memory in 1620 and 8008 MHz allow effectively to clear the crypto currency. Triple cooler, located on the board, stably cools the graphics card, not allowing it to overheat during operation. The energy efficiency of 480 is 150 watts. With such high performance indicators, this is not so much. Therefore, this video card is perfect for beginners and professionals alike. In the rating of video cards for ether mining, this card can be called the best.
Among all miners, both professionals andbeginners, special attention is attracted to RX 470 and Nvidia 1070. Users appreciate them for their low cost and power consumption. That allows with a small starting capital to quickly enter the sphere of mining, while earning income in a short time. It is worth noting that such a large demand for video adapters affected their cost and availability. To date, their price has increased significantly. But the problem is not only this, but the fact is that several cards are used to compile the farm. Therefore, they are bought in large batches, and it is difficult to buy them now in the store, since they simply do not exist.
The Future of Mining
Simple lovers to break into the world of mining is not sojust. The basic capacities remain for the big companies which are capable to invest in this business of considerable money and to equip farms with professional ASIC. The increase in the number of production capacities also increases the complexity of computing hashes. And this creates additional barriers for novice miners. Most likely, in the future, mining will be captured by high-tech boards and devices corporations.
In the end, it must be said that for the first time the bitcoinsappeared in 2008. As of the end of 2009, about 1 dollar could be received for about 1,000 bitcoins. During the development of the system there were many ups and downs of the course. Now, at the beginning of 2017, for 1 bitcoin it is possible to gain about $ 1000. Those who timely began to mine, today have already become millionaires.
