Ethereum mining, GPU RIG, and "Asics"
The AMD chip from Hawaii to Vega is an AMD chip with massive raw performance.
Historically AMD cards have always been the most popular for their performance for GPU mining. Each generation since the HD 5xxx contains one or more flagship cards and is particularly popular with minors who are more or less comfortable depending on the algorithms. Among the old cards still of interest, graphics cards AMD Radeon HD 7950. The interest in mining ethereum the R9 290/390 and 290x / 390x are capable of achieving hashrates higher than the current RX 570 and 580. The maximum output for both GPUs is between 31 to 33 MH / s. The counterpart comes from the power consumption of these absolutely insane cards (between 250 to 300 watts) which restricts their value. And limits the possibility of profiting from them. This electrical consumption also complicates the rig assembly because the cards require more connections and a better-ventilated environment and almost identical performance (for the RX470 RX480 RX570 RX580) for two times less power consumption. The model's onboard memories and bios settings can vary. GPUs based on the Polaris architecture are currently the benchmark for mining.
The Fury cards based on the Fiji architecture were released for a very limited time. The release of their equal-performance Polaris GPUs meant they were no longer competitive with the 290/390 GPUs, so they lost their appeal. If they had offered superior performance at lower consumption thanks to their HBM memory chips, then their price might have been comparable to that of the 290/390 GPUs. The availability of the engraving fineness on the GPUs and especially for Polaris is not very good. The peculiarity of their architecture which is less democratized among developers in front of the Polaris generation has never made it an interesting alternative for minors except in the case of an acquisition. It is a great deal. RX Vega 56 and 64 also have HBM memory chips (2nd generation) and present interesting performances on ethereum (respectively 40 and 44Mh / s). However, their high tax may discourage the purchase of the design of a rig intended to mine only Ether. On the other hand, HBM memory may be relegated to mining ethereum. chips in Vega GPUs prove to be very efficient and cost-effective on the Cryptonight algorithm.
Nvidia cards are expensive, but they use little power.
In terms of raw performance, Nvidia graphics cards are generally more efficient than AMD graphics cards. However, this difference is partially offset by lower consumption for the same performance. For example, a GTX 1060 6GB that we find at prices equivalent to the RX 580 offers maximum performance, but only consumes less energy than the RX 580. The GTX 1060 6GB has a performance of around 24-25MH/s (against 28-30MH/s) but consumes less power. Currently, the best performing GPUs per watt consumed ratio on the market is available to users and may be a wise choice for any person or company needing to limit the power consumption of their computer. These cards are good for mining cryptocurrencies. The GTX 1070 and 1080 cards will run at 30 to 32 mega hashes per second, and the GTX 1060 can expect peaks that range from 40 to 50 gigahashes per second. The Geforce GTX 1050Ti 4GB is also a good card for mining. You may use an inexpensive rig for mining. It is at least 14 MH/s and uses less than 60 watts of power. The industry-standard 1x PCIe adapter may be used to connect this miner to your computer. This allows you to save space by omitting the 6-pin PCI-E connector on the GPU, which saves money on the cost of the PC. However, this miner does not fit into a standard 1x PCIe slot but instead requires connection via a 16 Be sure the risers are correctly assembled before using them to mine.
The "Asic" ethereum
There are no proper ASICs designed to mine ethereum or any other currency based on the algorithm (ethash). As a reminder, an ASIC is a machine made up of chips intended for a specific application. Some manufacturers currently offer dedicated ethereum mining machines composed of multiple chips. Some miners are building mining rigs that they will use for mining only. These machines do not have room for expansion, or they would burn out by the time they reach their limit. If a miner's machine is efficient on paper but uses more power than traditional rigs, it has no versatility and no potential to evolve. It has no resale value should a major evolution occur on the cryptocurrency market. If you want to gamble, purchase a machine that resembles a mining rig. A well-configured and maintained computer will approach the performance of these pseudo-ASICs and will retain its value over time.
Cryptonight and Monero GPU mining and ASIC resistance.
The Cryptonight algorithm first made public by the Monero cryptocurrency was believed to be ASIC resistant and to guarantee anonymous transactions. The very active developers have always sought to favor GPU mining and strongly reject the idea of leaving the network controlled by ASICs. Many forks and spinoffs were produced, some of which tried to eliminate ASICs. Cryptonight algorithms are used by different cryptocurrencies. The main network is that of the Monero cryptocurrency which uses cryptonight V7 and has a particularly active community.
Nvidia Out, Vega, and the HBM
Nvidia cards produce a hashrate that is too small for cryptonight, but the RX Vega is the only one that uses hbm2 memory. The Vega 56 can produce a hashrate greater than 1900 hashes per second for cryptonight. The consumption of more than 150 watts does not produce any additional benefits.
FPGAs announced on cryptonight
While the developers have promised regular algorithm updates to avoid the deployment of ASIC FPGAs may be the best way to mine while consuming less energy. Currently, there has not yet been a full delivery of FPGAs, but the advertised price/performance ratio seems to be equivalent to an RX. Vega with higher investment. The promised power consumption would be divided by six or seven, so it would be more efficient than Vega. At Mining-boost we are currently studying the possibility of offering such products.
