What can mining legends AMD Radeon HD 7970 and R9 280X in 2019

amd_radeon_r9_7970_mining_2019 Released in 2012, the new tune of AMD Radeon HD 7000 graphics cards with then breakthrough GCN 1.0 engineering, according to many miners of the first wave of interest in cryptocurrencies, gives this generation of television cards a cult condition, because it is this generation of television cards, and in particular the Radeon HD 7970 and Radeon R9 280X, that were most popular and effective in all the chief era of cryptocurrency mining on GPUs : Bitcoin in 2012-2013, Litecoin and Dogecoin 2012-2014, Monero and Dash ( Darkcoin ) 2014, Ethereum 2015-2016 and Zcash in 2016 – 2017. In addition to the modern GPU architecture, AMD Tahiti chips at that time had the most energy-efficient 28nm process technology and 384-bit GDDR5 memory interface. For example, the Radeon R9 7970 video recording circuit board in the early epoch of Ethereum mine in 2015 showed 27-28MH/s, but its successor RX480 ( RX580 ) after 4 years, alone 24-26Mh/s ( excluding changes in memory timings ). But this was in 2015, and in 2019 everything changed dramatically : Bitcoin, Litecoin, Dash, Zcash under Asics, Ethereum is not available for mining with 3Gb memory, most modern miners do not support television cards with the first generation GCN architecture, and the march engineering is 28nm now it looks extremely ineffective. Despite this, the Radeon R9 7970 and R9 280X remain a sufficiently brawny mine solution for cryptocurrencies and how these mine legends will behave in 2019 in our article .
The experimental video menu will be the Power Color Radeon R9 280X 3Gb, which has been preserved to this sidereal day since the hot 2013, when its GPU bit mercilessly fried up to 90 degrees when mine Litecoin and Dogecoin using the Scrypt algorithm .

Hashrate of AMD Radeon R9 280x 3Gb video card in the realities of mining 2019

quiz stand :
megabit : Gigabyte DA780T-D3L
central processing unit : Athlon2 X2 250

As you can already see, depending on the size of the DAG file ( era ) on the Ethash algorithm, the video recording menu shows different results. And with the grow of the epoch, the performance of the 280X graphics circuit board begins to plummet. The same position was observed with the immediately popular RX480 / 580, but this was fixed in the drivers, while older video cards did not deserve such attention from AMD. however, you have the opportunity to increase the hashrate by 10-20 % of your beginning and second generation GCN video cards by reducing memory timings. This choice is available on the Linux HiveOS operating system .
In the table we did not incidentally indicate the result for the sixtieth earned run average, because it is at this earned run average that the REOSC Ecosystem cryptocurrency is now mined, not a lot inferior in Ethereum profitableness. But since Ethereum Radeon R9 280X itself can not be mining due to the lack of 3Gb memory, therefore now for R9 280X and R9 7970, REOSC mine will be the best choice with an income of 0.18USD per day excluding electricity. But at the like clock, your electricity should not cost more than 0.07USD per kilowatt, otherwise mining REOSC on 280x video cards will no farseeing be profitable .
You can independently calculate the profitableness of mining R9 280X on the web site Profit-mine.com, particularly since all the data from this test is available on this calculator for automatic rifle calculation .

It is worth noting that the R9 280X video card shows good mining results by algorithm : Beamhash2 and Equihash144/5 by nowadays ‘s standards .
conclusion : buy now only for mining an AMD Radeon R9 7970 or R9 280X video card is surely not advisable, because now on the grocery store there are many offers for more modern and energy-efficient video cards RX470/480 and RX570/580 at a price not much more. But at the like time, the integral assortment of mining software will be available to you, i.e. You will have access to a wider survival of algorithm for mine and at the lapp clock time with better optimization. For those who already have such video recording cards or are just going to buy for games, they can besides use them for mining with low income on Beam, Monero or Ethereum forks, this will be specially genuine for those whose electricity costs less than 0.05USD per kilowatt .
