This way, you can maximize your profits and start making your initial investment back as quickly as possible. As far as how good it is for mining, it can deliver a That is, if you can afford that high price tag. The Nvidia GTX Ti is still among the most powerful graphics cards out there, even in the face of its successors. It boasts Titan X-equivalent gaming performance and impressive cooling performance. More importantly for those mining for cryptocurrency, this GPU can deliver a And, it touts many features that are actually usable from day one.

It has been reported of delivering a View Deal. Please deactivate your ad blocker in order to see our subscription offer. Specifications Core Clock: MHz.

Memory Clock: 14 Gbps. Power Draw: W. Outputs: DisplayPort 1. Reasons to avoid - Still kind of expensive - Founders Edition card is heavy. The strong metal casing features a tongue and groove system which allows for the neat arrangement of multiple miners. The APW3 requires a minimum Volts to function and does not ship with the necessary 16A power cord. While an integral PSU makes for a compact and convenient miner, there are few other reasons to recommend such a setup.

The S7-LN also excludes a cord. Note: Before you buy an Antminer S7 make sure you already have Bitcoin mining software and a Bitcoin mining pool. These prices can be expected to fall further as the S9 and other superior mining hardware becomes the new standard.

With careful tweaking, it may be possible to profit from an S7 even at 15c power. The same calculations adjusted for the Hash Rate and Power consumption of the S7-LN produces slightly more encouraging results:. Naturally, the hotter the environment, the more energy the fan s will consume to cool the unit. The S7 is twice as efficient as the S5 at converting all this energy into bitcoins; it requires a modest 0.

Setting them up via the MinerLink GUI is a simple process, requiring only your mining pool credentials to begin mining. The units will automatically begin hashing upon powering up, which can be helpful in the event of power failure. S7 connectivity is via Ethernet only. They are both cooled by dual fans. A dry basement is an ideal location.

This peak was reached on May 24 th Such tremendous growth has been spurred by major investment into Bitcoin mining technology and operations. Profits have accumulated where mining is most profitable China , with the result that several competing operations eg. KNC have been forced out of the industry. We have tried to calculate the amount of money that the Chinese have invested in mining, we estimate it to be in the hundreds of millions of dollars.

Even with free electricity we cannot see how they will ever get this money back. The same Chinese competitive advantage has been doubly effective at squeezing the profit-dependent hobbyist miner from the market.

With the block reward halving looming, the profitability of all but the most efficient operations will likely be challenged. Given that profits derived from the current generation of mining hardware are dwindling and will likely reach negative returns post-halving:.

Can the new S9 change the game for smaller and hobby miners and restore their lost profitability? Note: Before you buy an Antminer S9 make sure you already have Bitcoin mining software and a Bitcoin mining pool. The first batch of S9s will be available for order directly from Bitmain from the 12 th of June.

However, the lower your electricity costs, the better your odds of the miner paying for itself within a reasonable timeframe. Judging value in this space is a complicated exercise, although it would appear that nothing vastly technologically-superior to the S9 is likely to be released in the near future.

The release cycle of a new generation of mining hardware every few months is likely to decelerate from this point on, as manufacturers have transitioned to cutting-edge 16 and 14nm designs. The on-going miniaturisation of semiconductors allows ever greater computing power and electrical efficiency, but the process cannot continue forever with the current technology.

The 16 nm fabrication process used in the manufacture of the S9 is a major improvement upon the 28 nm design common to other modern mining devices. Although a 10nm process is on the horizon for , further increases beyond that remain theoretical. Further, the design and manufacture of any 10nm Bitcoin mining hardware is likely to take at least a year. Our guide on the best bitcoin wallets will help you get one fast and for free. Read it here! The good news is that existing power supplies, at least those of sufficient wattage, are fully compatible with the S9.

A total of chips, spread over 3 circuit boards, are combined to achieve this phenomenal hashrate. Note that Power Cost will be specific to your location and that Difficulty changes every 2 weeks, usually to the upside….

Your Pool Fees will be determined by your mining pool; although the S9 is plenty powerful, a single unit is highly unlikely to find any blocks when solo-mining.

Of course, such impressive results assume all factors stay constant which is hugely improbable in the ever-changing world of Bitcoin! The cutting-edge manufacturing process is what makes the S9 the most electrically-efficient mining device to date. It uses a mere 0.

The S9 consumes about W more than the S7. Apart from the power supply, the S9 is a self-contained unit. It requires no connection to another computer to interface with other Bitcoin nodes. The S9 performs reliably in any well-ventilated space, whether a single or several unit s kept in a spare room or hundreds to thousands of units in a large mining center.

On the other hand, the halving could bring about a higher Bitcoin price and reduced competition, increasing profitability. It is likely to remain profitable for far longer than previous generations of ASIC miner, although ROI cannot be guaranteed given the inherent unpredictability of Bitcoin mining. Bitmain is regarded as one of the most influential companies in the ASIC mining industry. Halong Mining is no longer around.

It seems they could not compete with the already established ASIC manufacturers, most likely because they could never fill their orders and get the partsd they needed to produce enough miners to make money. The DragonMint W power supply is strongly recommended, though not mandatory. Each miner requires its own individual power supply. Professional mining hardware runs optimally at V, hence why mining farms step down their own electricity supply to V.

In any case, it would be a good idea to buy the DragonMint power supply. These PSUs will get the job done, but they are not ideal for optimum mining performance. Consuming merely 0. Keep in mind that exact power consumptions vary, especially depending on which power supply you are using.

Take a look at the projected mining profitability of a single miner :. The Antminer R4 hashes at up to 8. BitFury was the first company to release 16nm chips.

As the saying goes nothing good comes cheap. With all the awesome features that come with the Antminer R4 you would expect its price to be high. Its price is among its cons because this may be too high for the average hobby miner. Once you setup your Antminer R4 you will see that its user interface has been well designed with the users in mind. All you have to do is enter your wallet address and mining pool settings before you start mining. It is also possible for you to customize settings such as the fan speed or the frequency.

With a hash rate of 8. Rest easy because most homes have an outlet that can handle Watts safely but also expect your electricity bills to rise significantly. Of course we assume that all factors remain constant which is almost impossible in the ever-changing world of Bitcoin. This means that the Antminer R4 will eventually produce a profit, but only if the network hash rate, Bitcoin price, and electricity costs stay the same.

All of those factors are a big IF, since the network difficulty almost always increases. So you are definitely taking on risk with this miner, and it may not be worth your time despite the many benefits it provides over other hardware. One of the most unique features of Antminer R4 is that it was designed to ensure the least possible sound with the maximum hash rate.

Antminer R4 replaces the traditional fan with a rotary blade system. The traditional fan has been the biggest source of noise for other mining hardware. Its fan speed is controlled automatically, ensuring that the noise is regulated. Bitmain recommends the use of an APW5 power supply. It also uses 28nm Xilinx programmable logic. It supports Gigabit Ethernet to ensure that mined blocks are submitted instantly.

Not only are the devices expensive but they also generate a lot of heat and noise, not to mention the amount of electricity they consume. Some of these problems mentioned above have been addressed and as a miner you can do it as a hobby while also making some money.
