Actual ASIC miners for bitcoin mining in 2021

The renewed interest in cryptocurrencies in 2021 pushed Bitcoin prices back to new heights, which in turn influenced the mining income of this cryptocurrency. Bitcoin miners again began to buy out-of-date ASIC miners Antminer S9 2016, because even they have begun to bring relatively good profit compared to the fact that a few months ago they did not even recoup the cost of electricity. And this is not to mention the more modern ASIC models SHA-256, which are several times more powerful and energy efficient than the S9. Next, we will consider all the currently relevant ASIC miners for mining bitcoin in 2021, which you can purchase. Next, we will compare the hashrate, power consumption and income of SHA-256 ASIC miners, so that you can better navigate the models and firms of manufacturers of various ASICs.

 

AMD Radeon RX 6700XT video card announcement. Mining performance forecast

On March 3, 2021, AMD announced a mid-range graphics card of the RDNA 2 generation - RX 6700 XT, which the manufacturer positions as a development of the RX 5700XT model of the RDNA generation. A distinctive feature of the RX 6700XT from the RX5700 XT, in addition to the improved RDNA technology, will be the use of a fast Infinity Cash cache, the use of Smart Access Memory technology and more advanced GPU and GDDR6 memory production processes. If in gaming applications the new video card has added significantly and can now compete with RTX 3060Ti and RTX 3070. Recall that the RX 5700 XT video card in games was at the level of RTX 2060 Super - RTX 2070. Either in Ethereum mining RX 6700 XT due to 192-bit bus memory, instead of 256-bit in RX 5700XT, the same performance increase as in games is no longer to be expected.

Goldshell has announced new models of ASIC miners: HS5, LT5, KD5 and KD2

The Goldshell company appeared on the ASIC miner market quite recently, but thanks to the successful Handshake models, the ASIC miners HS1 and HS3 and Scrypt ASIC X6 have already gained popularity among the miners. Recently, to its already not small assortment, the company announced new models of ASIC miners for the Scrypt (Litecoin, Dogecoin), Handshake (handshake), Blake2b (siacoin), Kadena (Kadena) algorithms. Among the novelties, it is worth noting ASICs for the Kadena algorithm (KD2 and KD5), as well as a new generation of handshake ASICs HS5, which received support for the second Blake2b algorithm, with which you can also mine Siacoin cryptocurrency.

Nvidia Announces GPUs for "Professional Mining" Cryptocurrencies

The latest news regarding Nvidia may be of interest to both miners and gamers, and Nvidia appears to be trying to take drastic measures to make gaming GPUs available to gamers. With the upcoming release of new Geforce RTX 3060 graphics cards on February 25, the company wants to make sure the new graphics cards can go public rather than being bought out by miners before they hit store shelves. The upcoming drivers for Geforce RTX 3060 will detect Ethereum mining-specific operating modes and will limit hashrate and mining performance by about 50%. Thus, you will only get 50% of the performance when mining cryptocurrencies than if the video card was working at full strength. For RTX 3060, the expected hash rate on Ethash is in the region of 40-45 MH / s (using memory overclocking) and if the drivers cut the hash rate of the video card by 2 times, you will only get 20-22.5 MH / s, and at a rather high price. This fact will make Nvidia RTX 3060 processors completely unattractive for cryptocurrency miners and video cards will appear on sale at more or less normal prices for players, and most importantly, they can be bought in regular stores, unless, of course, mining enthusiasts find a solution to bypass the performance blocking for RTX 3060.

Ethereum mining on laptops with Nvidia Geforce RTX 3060, RTX 3070, RTX 3080 graphics cards. Hashrate and ROI

By the middle of February 2021, the mining boom of cryptocurrencies reached gaming laptops with integrated Nvidia graphics cards of the RTX 3060, RXT 3070 and RTX 3080 levels. 3000 series of video cards in the version for laptops also show a fairly high hash rate on the ETHash algorithm compared to other laptop models of video cards. Moreover, the price for a megahash when buying such laptops is about 40USD for a megahash, which is not much more expensive than buying a separate video card for mining. And this despite the fact that a laptop is a complete device to which you do not need to buy motherboards, processor, memory, power supplies and a monitor. Accordingly, the return on investment for modern, expensive gaming laptops was even faster. Next, we will talk about the performance of such laptops in mining, how many megahashes they give on the air, find out their power consumption, as well as payback or income per day.

The current table with the hashrate of videocards for 2021

The beginning of 2021 was marked by another increase in interest in mining cryptocurrencies, but like the previous 5 years, only two cryptocurrencies are the main focus of miners: Ethereum and Bitcoin. Ethereum, as before, is mined by miners using video cards, and Bitcoin is still mined by ASIC miners. If with Bitcoin mining everything is stable and predictable in terms of equipment selection, because ASIC manufacturers of SHA-256 miners have not made revolutions for a long time and each new generation of ASICs is slightly better than the other. Then the situation with mining on video cards is constantly changing, tk. over the past year, AMD and Nvidia's next-generation video cards have gone on sale, which can offer much more energy efficiency than video cards released just a year ago. In addition, one can observe an increasingly strong division of miners into two castes. Those who can mine ethereum on their equipment and those who do not. And this "divide" is at the border of 5Gb video memory, tk. for mining Ethereum at the beginning of 2021, you need exactly that much video memory.

Return of the King. AMD Radeon 7 - 116MH/s on the ETHash algorithm.

The AMD RADEON 7 video card, immediately after it went on sale in February 2019, confidently took the pedestal among all video cards as the most powerful and energy efficient video card for mining Ethereum cryptocurrency. The power and superiority of the Radeon 7 lasted almost two years before the release of the Nvidia Geforce RTX 3080 and Geforce RTX 3090 graphics cards with GDDR6X video memory on board. If a Radeon 7 video card with HBM 2 memory produced 80-90 MH/s, when all the other competitors were at most capable of 55Mh/s at twice the price. Then, against the background of the new products RTX 3080 (95-105Mh/s) and RTX 3090 (100-120Mh/s), the Radeon 7 was defeated and displaced from the first line of the most powerful and energy efficient graphics cards for mining on the Ethash algorithm.

Oblivion did not last long, because with the release of the 8th version of TeamRedMiner , enthusiasts and mining experimenters were able to get 116MH/s out of the old man instead of the previous 80-90Mh/s, or vice versa, with not the highest hash rates (90-100MH/s), the Radeon 7 video card began to show miracles of energy efficiency.

We will discuss how to get the new mining king from AMD Radeon 7 in our article.

Income from mining on video cards. Factors affecting the payback of equipment.

When a cryptocurrency once again hits new records in its value, the excitement around cryptocurrencies is observed not only on crypto-exchanges, but also in computer stores, where video cards, power supplies and other elements necessary to create a mining rig on video cards are bought for a clean one. Such an increased demand for video cards is due to the high profitability of mining and the rapid payback of equipment. When a person who has not previously encountered mining sees on mining calculator sites the profitability figures of 300% per year or even more, then, not knowing the many nuances of how such calculations are made, he can make a big mistake by buying equipment at an inflated price in the hope of a payback at 3 months, which are drawn to him by various mining calculators. Further in this article, you will learn about all the factors that affect the income from mining on video cards and how they can affect the payback of mining equipment in the future.

 

AMD Ryzen 7 5800X - Monero Mining Performance, RandomX Mining Algorithm

Earlier on the pages of the Cryptoage.com website, we already gave information on the performance of the new AMD Ryzen 5 5600X and Ryzen 9 5900X processors in Monero mining, but we did not deservedly miss the Ryzen 7 5800X processor. Today we will fix this oversight by testing the 5800X on the RandomX mining algorithm. The Ryzen 7 5800X is an 8-core processor with 16 threads and 32MB of L2 cache, generation ZEN3, made using 7nm technology.

Divine salvation. Converting AMD Radeon RX 480 4Gb to RX 480 8Gb in 5 minutes

Now all video cards with 4Gb video memory in Ethereum mining are slowly and surely dying, because instead of the 30-32Mh/s required, RX480 and RX 580 4Gb give out 16-18Mh/s in zombie mode. And with each new era on the Ethereum network, the "health" of such video cards will only deteriorate by 1.5MH/s. There are forgotten knowledge in the world, with the help of which you can turn RX 480 4Gb into RX 480 8Gb in an instant, i.e. resurrecting and returning them to a full life, where they can "breathe deeply" and delight their owners with graceful 30-32MH/s.

Actually, we will share this knowledge with you today.

But we warn you right away, salvation is not waiting for everyone.

Nvidia announces Geforce RTX 3060 12Gb graphics card with not the best performance for mining

On January 12, 2021, Nvidia announced the launch at the end of February 2021 of another Amper generation video card called Geforce RTX 3060. Unlike the older RTX 3060ti model, the new product received a different GA106 GPU instead of G104 and a stripped-down memory bus to 192bit. The recommended price for Geforce RTX 3060 was announced at the start of sales at 330 USD, which, of course, is cheaper than the RTX 3060Ti, but how to correlate the capabilities of these two video cards in mining to price and power consumption, we will try to draw a conclusion about the advisability of buying this or that model.

Apple M1 processor tested in mining Monero cryptocurrency

Apple recently launched the new MacBook Air and MacBook Pro 13 laptops with an all-new in-house developed processor called the Apple M1, which in some applications shows wonders of performance and energy efficiency compared to the same laptops, but on Intel processors. According to Apple, the new 8-core ARM processor M1 shows up to 3 times better energy efficiency compared to competing products, which has already broken many copies on the Internet. With the advent of the new version of the XMrig miner 6.7.0, in which it became possible to test the Apple M1 in mining the Monero cryptocurrency on the RandomX algorithm, and the results of this testing may add a little more heat to the dispute between Apple and Intel and AMD, which is already quite hot.

Canaan AvalonMiner 1246 - new 12th generation SHA 256 ASIC miner on sale from January 2021

The company that manufactures Bitcoin ASIC miners Canaan has presented the first model of a new generation called AvalonMiner 1246. Compared to the 11th generation model range, the ASIC miner with the xx46 index is not the most productive and energy efficient solution, because there are also models with the xx66 index. If we compare the current AvalonMiner 1146 with the new 1246, the energy efficiency has improved by 37% from 52 J/TH to 38 J/TH. Unfortunately, the company does not indicate which ones. the process is used to produce new ASIC chips, a new 5nm or an improved 7nm, so it is difficult to predict how much Bitcoin ASIC performance can be expected in the near future. 

AMD Radeon RX 6900 XT - Ethash mining hashrate, Ethereum cryptocurrency

On December 8, 2020, AMD's most powerful graphics card from the latest lineup, the Radeon RX 6900 XT, went on sale at a recommended price of 999USD. But like its predecessor, the availability of new items for purchase leaves much to be desired. However, a couple of copies still managed to get to the enthusiastic miners who have already tested the Radeon RX 6900 XT in mining the Ethereum cryptocurrency.

Nvidia Geforce RTX 3060Ti - First Ethereum Mining Test

On December 2, 2020, the Nvidia Geforce RTX 3060Ti video card became available for tests, and tests in Ethereum mining were also not long in coming. A similar video memory subsystem of the RTX 3060Ti video card with the older model RTX 3070 (8Gb, GDDR6, 256bit) gave us hope for similar results in Ethereum mining, in fact, let's check what result RTX 3060Ti achieved using the ETHash mining algorithm.

AMD Ryzen 5 5600X - hashrate based on RandomX algorithm, Monero cryptocurrency.

Previously, we have already tested a brand new processor from AMD Ryzen 9 5900X in mining and, unfortunately, it did not show the impressive results that everyone was expecting from it. Today, its younger 6-core brother, Ryzen 5 5600X, is next in line for tests. Recall that a similar 6-core AMD processor of the previous generation 3600X showed 6500H/s in mining.

AMD Radeon RX 6800 and RX 6800XT - the first test in the mining of Ethereum cryptocurrency

Along with the start of sales of new AMD video cards - Radeon RX 6800, RX 6800XT, the first tests of these video cards in mining the Ethereun cryptocurrency (Dagger-Hashimoto mining algorithm) became available. As expected, RDNA2 video cards are not far from the previous generation of RDNA (RX5700) in terms of performance in ETH mining. the video memory subsystem has not undergone drastic changes. The 256bit memory bus and GDDR6 are still used, which has become a little faster. The mythical Infifnity Cash, on which many pin great hopes in these tests, did not show itself in any way.

AMD Ryzen 9 5900X - RandomX hashrate, Monero cryptocurrency

With the release of AMD's ZEN 3 generation processors, everyone has witnessed a historic event when AMD processors once again became the ultimate processor of choice in all use cases. The last time AMD processors received such a title was back in 2004 with the release of the first 64-bit Athlon 64 processors. FX processors. Those. Since the release of Bulldozer microarchitecture processors in 2011, AMD has firmly established itself as the best processor for cryptocurrency mining. Considering that ZEN 2 processors showed themselves at their best in Monero mining on the RandomX algorithm, then the new generation of ZEN 3 will not be an exception. We are most interested in the moment how an increase in IPC by 19% will affect mining, for this we took a Ryzen 9 5900X processor (12 cores, 24 threads) and checked its performance in mining.

AMD Radeon RX 6800, RX 6800 XT, RX 6900 XT video cards announced. Mining performance forecast

On October 28, 2020, AMD introduced the long-awaited new-generation RDNA 2 video cards called: Radeon RX 6800, RX 6800 XT, RX 6900 XT. This time, AMD did not deviate from the established tradition of 2020 and the presentation of new products once again surprised and delighted miners and computer enthusiasts. And first of all, this concerns the release of video cards not only competing with the best solutions from Nvidia, but offering even greater performance in games and at a lower price (RX 6900 XT). Probably no one expected such a breakthrough from AMD. The last graphics card from AMD to impose a worthy competition in the top segment was the Radeon R9 290X, which was at or better than the GTX 780 Ti in performance. And this, for a second, was as much as 7 years ago in 2013. All subsequent AMD solutions in the top segment (Fury, Vega, Radeon 7) could only compete with Nvidia's average performance video cards (GTX 1070, RTX 2070). If the gaming performance of the new generation of video cards was shown at the presentation by AMD itself, then we need to figure out the performance in mining ourselves until the video cards go on sale on November 18. Until this happens, let's try to predict the hashrate of the RX 6800 and RX 6900 video cards in mining popular cryptocurrencies based on the official technical data available after the presentation.
