Best Ethereum Mining Hardware 2018 – AMD vs. NVIDIA vs. Geforce

Mining can be understood when used in the gold analogy for cryptocurrencies. We are aware that gold and other precious metals are scarce and so are digital tokens so the only way to increase their quantity is by mining them. Mining is also a method to secure the cryptocurrency network by creating, verifying and propagating blocks in the blockchain. In this article, we will go through best Ethereum mining hardware, but first, let’s jump into the basics.

Purpose of mining

Most bank customers trust their services because they are known to keep an accurate record of all transactions to prevent fraudulent activity. Blockchains, however, work in slightly different ways. The entire network verifies and adds transactions to their public ledger, instead of control is in the hands of a sole intermediary. Although the whole purpose for the absence of an intermediary is for trust minimizing, there still needs to be a physical entity that secures all financial records to make sure no one cheats.

Mining is one such innovation that makes decentralized record keeping a legitimate option. Mining keeps track of transaction history while preventing fraud.

How does mining work?

The consensus is reached by selecting a block of the highest level of difficulty. Miners produce blocks which the others check for validity. A block is considered to be valid only is it contains Proof of Work (PoW). But Ethereum 1.1 is likely to be replaced with Proof of Stake model.

Miners engage in a quiz by trying to assess and guess the right answer to the puzzle until one of them wins. Primarily, the miners run the transaction block’s unique header data which includes details like time-stamp and software version through a hash function. A hash function is used for indexing and identifying items in a huge database of information because it is easier to find a short hash value than a long string or text. While mining, a hash returns a series of random letters and numbers of a fixed length. The miner finds a hash that matches with the target and is thereby awarded ether and the block is broadcasted over the network for each node to add to their own copy of the ledger.

Any miner participating in the network is referred to as a node and each node’s expected value from mining is likely to proportional to their mining power or hash rate.

When a miner finds the hash, the second miner will stop working on that block and proceed to the next. The puzzle solving method is called ‘ proof of work ‘ because there is no chance of cheating and guessing the right answer. Every 12-15 seconds a miner finds a block and the algorithm shifts its difficulty level according to the miner’s speed in order to provide the 12 second solution time. Miners earn these ether which primarily depends on luck and the amount of computing power put into it. The proof of work algorithm that ethereum uses is called ethash that are designed to require more memory to make it difficult to mine using expensive ASIC’s. ASIC’s are mining chips which is the only profitable way of mining Bitcoin.

Requirements of Ethereum mining

Software requirements for mining

  • Depending on the GPU selected, you will need the latest drivers.
  • If your driver doesn’t include features to monitor overclocking and temperature rise, you will need to find a separate utility to provide the needs.
  • Make sure to have proper Ethereum mining software.

Hardware requirements for mining

  • A reliable and cost-friendly power supply.
  • At least 4 GB of system RAM.
  • If you wish to use multiple GPUs, make sure to have well-ventilated situations.
  • Reasonably fast internet supply.

Mining rewards

  • A successful PoW miner of the winning block will be awarded the following :
  • A  reward for the winning block consisting of exactly 3.0 ether.
  • All the gas that was consumed during the execution of transactions made by the winning block will be compensated. The gas cost incurred is transferred to the miner’s account.
  • ‘Uncles‘ are stale blocks which were the parent blocks or ancestors of the including blocks. An extra reward is allotted for using Uncles for using Uncles in the block in the form of 1/32 of the number of Uncles used. The user receives 7/8th of the static block reward.

Ethereum mining hardware

Miners look for efficient mining hardware to reduce electricity bills and cut down costs.

Remember before getting hardware, make sure to have ethereum mining software, an ether mining pool as well as an ethereum hardware wallet for the storage of ether. To mine ethereum, a hardware called Graphics Processing Unit ( GPU ) is required. Originally intended to use computer CPUs, miners later found that GPUs gave them more hashing power.

In order to select the best GPU for mining Ethereum, one must decide how powerful you want your rig to be and how much you are willing to spend on electricity and the GPU itself.

While some GPUs have more hashing rate, they also consume a huge amount of electricity. Miners often buy the best mining GPU from Amazon or eBay and depending on whether your retailers can ship it to your country, buying GPUs will be an easier task. The cost of electricity varies with different countries and miners from countries like China and Iceland often have an advantage over their counterparts owing to the cheap electricity costs.

Before buying a mining card, you must be aware of overall income and Return on Investment also known ROI. With an ethereum mining calculator, these values can be calculated by considering energy accounts and possible fees. A mining calculator can give a better assessment of the different graphics cards. More popularly used calculators are Ethereum Mining calculator and Coinwarz’s profit calculator.

For mining, AMD ( Radeon ) or Nvidia ( Geforce ) graphics cards are preferred. In earlier days, AMD cards had better performance but the recent Nvidia cards outshine them in terms of performance. While AMD cards are cheaper and offer more potential for modification, Nvidia has better overclocking support within Windows. Due to the popularity of GPU based mining for cryptocurrencies, the costs of mining has shot through the roof which has further lead to shortage of cards with efficient quality and manufacturers find it hard to create cards to meet the demands of miners.

The initial price paid for your mining card is the amount that the card will pay for itself, based on your mining profits. Hashrate of a card is the rate the card achieves under ideal mining conditions with Claymore 9.6 but without any overclocking. A card draws a viable amount of energy while mining and is indicated by power draw and measured at the outlet.

Efficiency can be determined by dividing hash rate with power consumption and for all obvious reasons, newer cards are more efficient. The rate of efficiency is an important factor because the greater the efficiency the more profit is made after calculating the ROI.

How long can you mine Ether?

The final level of Ethereum indicates the transition between Proof of work ( PoW ) and Proof of Stake ( PoS ). Once this level is achieved no more ether can be mined.

5. NVIDIA GTX 1070

It can mine at a hash rate of 30 MH/s while consuming just 100W of power.

It has a VRAM of 8GB GDDR5 and a power draw of 25W. The initial mining performance was quite noteworthy while the stock clock card mined Ethereum at a hash rate of 31MH/s. A key feature is that a lower price, it brings out the performance qualities of the 1080 model. It has a GPU architecture in Pascal and a memory speed of 8 Gbps.

GTX 1070 – Which one to buy?

Despite having 3 fans for its cooling system, users still complain that GTX 1070s have the weakest fans compared to its counterparts.

While Founders Edition GPUs have great stability and above average hash rate, their fans tend to be among the noisy ones.

ASUS Strix is hugely sought-after. Despite its high cost, users get a good hash rate and quiet and durable fans. The Zotac 1070 AMP has a very good hashrate and is attached with two coolers.

When in high demand, GTX 1070 can get quite overpriced, but if you find it at a decent price, it has proved to be a good performer. By using an overclocking feature, your hashrate can increase by 10% to 31MH/s. With plenty of VRAM and reasonable power consumption, it is highly sought after by miners.

 

6. Geforce GTX 1080 Ti

The GTX 1070 Ti is being dubbed as a new-generation GPU comprising of a ton of interesting features.

The GTX 1070 can be configured up to 32 MH/s of hashrate which can be achieved using GTX 1070 Ti. It has a power draw of 120W along with an 8GB GDDR5 256 bit memory.

One of the key features is the cooling system. The card features three fans and each fan is turned off by default and will start spinning only after the card reaches 64 degrees.

The Windforce fans along with the composite heat-pipes make it 50% more efficient than GTX 1070 FE. With a high amount of RAM and great hash rate, this card can mine Ethereum for years together. However, the cards high upfront costs and power draw means that profitability will be a slow process. It is sold at $800, but mining demand can increase the price to over $1000.

Also, note that GTX 1070 Ti features 432 CUDA cores which makes it faster for Ethereum mining because of its 8GB GDDR5 memory at 8 gigabytes per second. The clock of 1070 Ti is 100 MHz higher too, and it is observed that both editions hash at the same rate no matter the difference in core strength. The memory subsystem performance showed that while mining, some of the GTX 1070/1070 Ti cards stayed at 2000 MHz while others dropped to 1900 MHz range. This can be resolved by manually overclocking the memory to its maximum to get the best results from the card. The NVIDIA Geforce GTX 1070 Ti Founders Edition can be bought at $449 which isn’t too expensive considering that GTX 1070 FE could be purchased at $399.

Pros

  • Great cooling system
  • Silent and good fans
  • Stylish and fancy design and interface
  • Excellent build quality, the use of high-end MOSFETs and capacitors adds to its lifespan and stability.

Cons

  • Low hash rate if used on factory settings.
  • Higher power consumption.
  • Price is considerably high when compared to its alternatives.

 

7. GeForce Titan XP

Although this model is priced at $1400 and is comparatively much more expensive than its counterparts, it has an impressive hash rate of 35 MH/s and can be clocked up to 42 MH/s.

The average power consumption of 200W. Packed with 12GB of GDDR5X memory, it has an effective data rate of 11 Gbps.

 

8. Titan V

The Titan V series has an average hash rate of 70MH/s and is priced at $3000. The expected power draw of 250W which is a minor drawback when compared to other cards. It has six graphics processing clusters and 5120 CUDA cores and is packed with a dual slot card with 12GB HBM2 RAM, and the total memory bandwidth reaches up to 652.8 GB/s.

Accompanied by a massive 21.1B transistor powering the TITAN V, it has a base clock of 1200 MHz and a boost clock of 1455 MHz

Its outer aluminum body is machine finished and heat treated for added agility and strength.

According to a few test run results, Titan V achieved a 70 MH/s for Ethereum mining and when overclocked it surged up to 77 MH/s. The card is a powered by a Volta-based GV100 GPU which is also found in Tesla accelerators. The card performed equally well with other cryptocurrencies also making it a suitable option for miners. NVIDIA Titan V stood testimony to the fact that the new Volta based GPUs would excel at mining and be the top toy sought after for mining. Owing to its spectacular hashrate, it is also priced pretty high.

However, a less expensive version of this card can be expected in the markets real soon proving to be the ultimate tool for Ethereum mining.

 

9. AMD Radeon RX Vega 64

With a hash rate of 30 MH/s and a power draw of 210W, this card has excellent mining performance loading with extreme clocking potential. The RX Vega comes in three different versions – a reference air-cooled card, a limited edition model, and a liquid cooled variant. All three cards clock the memory at the same 945 MHz base clock. However, the liquid cooled model increases the base clock speed by 12.8 percent and also increases the boost clock to 8.5 percent.

Vega is a part of the AMD GPU architecture hence it is not in abundance and is hard to find.

The RX Vega features all 4096 stream processors present on the chip and can match the overclock potential of Titan XP at almost half the price of $1300.

While the air-cooled produces too much run heat, the special edition can stay cool enough to draw 42 MH/s at just 300W. It comes in two versions of the RX Vega 64 air cooled and RX Vega 56 cards and looks nearly identical.

 

10. AMD R9 390

Another new high-end card produced by AMD, it is priced at $540 it has a hash rate of 30 MH/s which gives it an impressive performance at an affordable price. Due to this, it may lack in availability.

This card has a power draw of 235W and was built using older yet upgraded hardware, it can prove to stand its own ground when compared to the NVIDIA Geforce GTX 980 series and is also less expensive. This makes a suitable and viable option for miners. A key feature of the 390X is that it uses Graphics Core Next architecture which has been used by AMD since 2011. The Hawaii core that was the base of the R9 290X series has been renamed as Grenada to build the R9 390X series. It has a staggering 2816 stream processors that are split into units with 64 individual processors inside. It is a big GPU that may require 6 and eight-pin power connectors.

The card is fixed with three fans which produce a considerable amount of noise. However, it is automatically turned off at a low load, which was a recently implemented feature.

These cards use a Graphics Core Next architecture which makes it fall behind NVIDIA’s Maxwell designs. It is a highly conventional card with the option of tweaking if you want to do something different. The R9 390X is competitive in terms of price, speed, and memory but falls behind NVIDIA in areas such as power consumption, noise generated, heat and overclocking.

Pros

  • Ahead of GTX 980 in terms of performance.
  • Cheaper than NVIDIA versions.
  • Board partner versions are also available.

Cons

  • More power consumption
  • Less versatile architecture
  • Many R9 390X models are bulky and heavy requiring both 6 and eight-pin power connectors.

 

11. AMD Radeon RX 580

It has a hash rate of 18.5 MH/s and a power draw of 185W and is a minor update of the last generation RX 480 cards that were produced. The RX 580 has a 1340 MHz boost clock speed paired with 8GB GDDR5 memory. Its specifications depend on which third-party manufacturer was used and also the amount of RAM.

The small upgrade in speed bring it in close comparison with NVIDIA Geforce GTX 1060, and the cheapest model is at 200 pounds. It has good cooling systems and uses a Polaris architecture which isn’t the popular choice for Ethereum mining. Long considered as the only choice for ETH mining, the RX 400 and 500 series is slowly being put out of use.

Pros

  • Excellent full HD performance
  • Decent 1440p performance
  • Lower priced cards have great value

Cons

  • Card lack compatibility
