Bitmain announced Ethereum ASIC miner Antminer E9 - 3GH/s, 2556W

Bitmain has announced a new generation Ethereum ASIC miner Antminer E9 with a hashrate of 3000MH/s (3Gh/s) with a power consumption of 2556W. In terms of hashrate, ANTMiner E9 is equivalent to 30 Nvidia Geforce RTX 3080 graphics cards, but the power consumption is more than twice as low. The date of the start of sales and the price of the device are not known at the moment, but now it is definitely not worth counting on a price cheaper than 15,000 USD. A hash rate of 3000Mh/s now yields an income of 240 USD per day. But the situation with payback can change at any time, both for the better and for the worse. Ethereum ASIC miner Antminer E9 has already been added to the Profit-mine.com website and you can check at any time what profitability this ASIC miner gives at the current time.

Bitcoin mining in 2021. Configuring ASIC miners

Bitcoin cryptocurrency is not just a new electronic money, but a whole technology for the secure transfer of value between people without the participation of banks, states or other intermediaries. Bitcoin became the first to use blockchain technology, in which mining or mining of cryptocurrency using computers has become one of the main elements of reliable cryptocurrency transfer, which is now trusted not only by crypto enthusiasts, but also by well-known banks and funds from all over the world. And the states using these developments are now designing new digital national currencies. But compared to national currencies, everyone can mine or mine bitcoin. What you need for this and how to start mining bitcoin, read further in our article.

Nvidia CMP 30HX mining graphics card goes on sale

In February, Nvidia announced the launch of a line of specialized video cards for mining called Nvidia CMP. This line of mining devices includes 4 models: CMP 30HX, CMP 40HX, CMP 50HX and CMP 90HX. Two months later, the first and simplest model of a video card for mining Nvidia CMP 30HX appeared in stores.The first video card in the CMP line was a model from vendor Gigabyte called CMP 30HX D6 6G with a declared hashrate on the Ethash algorithm of 26MH / s, which corresponds to Geforce GTX 1660 Super video cards and GTX 1660 Ti.

Prices and payback of video cards in mining for 2021

Due to the high profitability of mining on video cards in all stores and around the world, it is now impossible to buy a video card at the recommended price. even at several times overstated prices, video cards of medium and high performance are sold out in a matter of moments. It is guaranteed that now you can buy a video card only from dealers at an even higher price. Today we will try to evaluate the payback of video cards at several times inflated prices for use in cryptocurrency mining and will help you with the decision to purchase equipment for cryptocurrency mining in the spring of 2021. As a bonus, you will also find out how many times the price of video cards has risen relative to their normal price.

The first test in the mining of the AMD Radeon RX 6700 XT video card on the Ethash and KawPow algorithms

Even before the start of sales of the Radeon RX 67000 XT video card (March 18, 2021), the first tests of this video card in cryptocurrency mining have already appeared on the Internet. As expected, the video card was checked for the issued hash rate using the Ethash algorithm (Ethereum cryptocurrency) and the KawPow algorithm (RavenCoin cryptocurrency). Both of these algorithms are sensitive to the memory subsystem of video cards. The Radeon RX 6700 XT has a 192-bit memory bus instead of the 256-bit one in the previous model Radeon RX 5700 XT, therefore the new product showed not the most impressive results in the mining of these cryptocurrencies.

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.
