All About BTC, LTC, ETH mining as well as other alternative crypto currencies
Bitmain has a new interesting offer for miners in the form of a lower hashrate ASIC miner for Bitcoin called AntMiner S7-LN that comes packaged with a 1KW Enermax ATX PSU. The new Bitmain AntMiner S7-LN apparently has less chips – 90x BM1385 instead of the 135 found in the regular S7 and as a result you get a bit more than half the hashrate at about half the power usage. The AntMiner S7-LN is rated at 2.7 THS hashrate and about 700W of power usage at the wall and can be yours for $291 USD without the shipping and taxes per unit – the miner and the PSU for it – with the shipping expected to start on June 2nd. The good thing about this offer is that the PSU is a regular ATX one so it can be used for a PC or a GPU mining rig and not only for ASIC miners when the time to shut down the S7-LN comes.
Bitmain AntMiner S7-LN Specifications:
– Hash Rate: 2.7 TH/s ±5%
– Power Consumption: 697W + 10% (at the wall, with Enermax, 25C ambient temp)
– Power Efficiency: 0.25 J/GH + 10% (at the wall, with Enermax, 25°C ambient temp)
– Rated Voltage: 11.60~13.00V
– Chip quantity per unit: 90x BM1385
– Dimensions: 306mm(L)*150mm(W)*275mm(H)
– Cooling: 2x 12038 fan
– Operating Temperature: 0 °C to 40 °C
– Network Connection: Ethernet
– Default Frequency: 700 MHz
– PSU: 1000W Enermax golden power supply
The only drawback is that the Bitcoin block reward halving is right around the corner, so in about a month and a half the coins mined by the miner will be cut in half. So now it might not be the best time to consider purchasing the current generation of Bitcoin ASIC miners even of the offer is an attractive one. So consider carefully whether now is the right time to purchase SHA256 ASIC mining hardware or better to wait for the halving and then consider what to do…
It seems that there is another product appearing on the market in the form of a X11 ASIC miner from a third company, though this one is apparently targeted at the Chinese mining community – the X11 ASIC Baikal Mini Miner. The miner apparently is capable of providing about 150 MHS X11 hashrate with a power usage of about 40 Watts thanks to the use of 40nm production process for the ASIC chips. There is no clear information about exact price, but it should be around 1-2 BTC or the equivalent in USD, though some shops have listed the device at a higher price than that. It is good to see more alternatives, but the big question is if the X11-based crypto coins are capable of handling the massive new hashrate that is provided by the ASIC miners that are getting produced at a fast pace with the competition heating up.
X11 ASIC Baikal Mini Miner Specifications:
– Hash Rate: 150 MHS (±10%)
– Power: 40 W (±5%) @ 0.27 J/MH (at the wall, with 25 C ambient temperature)
– Power supply: DC 12V 5A Power Adapter with 2.5 DC Plug (Not included)
– Interface: Ethernet
– Operating Temperature: 0 ~ 40 C
– Dimension: 140mm (L) x 100mm (W) x 95mm (H)
– Weight: 475 grams
It seems that the miner uses a board like Raspberry Pi for providing a web-based interface for control and monitoring of the mining process and there is no need to plug it in to a computer, all you need is power and a network cable plugged to the device. With the right price and availability outside of the Chinese markets this device can be an interesting option for home miners due to the relatively simple open design and the lower noise level, so you might want to keep an eye out for the Baikal X11 ASIC Mini Miner. For the moment we have not been able to find a way to order one of these devices to do a proper review, but we are going to keep trying.
PinIdea is the second company to release X11 ASIC miners and apart from their large DR-1 miners that apparently had some issues with shipping they are ready to start shipping smaller X11 USB ASIC miners in a few days. PinIdea X11 USB ASIC Miner DU-1 is supposed to offer about 9 MHS X11 mining hashrate with about 7 Watts of power usage (1.4A at 5V), so you will need to use these with powered USB hubs capable of 2A per port to have some extra headroom. The price of the X11 USB miner DU-1 is set at 9 DASH or about $65 USD with the current exchange rate of DASH/USD (the price should include shipping cost) with shipping scheduled to start on May 24th.
The small X11 USB ASIC miners should help provide the decentralization that X11 crypto coins need after the first large ASIC miners hit the market with a lot of hashpower in the hands of a few users. Not to mention that many people will probably get these miners just for fun and not considering ROI time and such as even though they are not that much powerful, they are still something fun to play with if crypto mining is your hobby.
We have actually pre-ordered the large PinIdea DR-1 X11 ASIC miner a while ago as we wanted to review it as we did with the iBeLink X11 ASIC miner, but due to the issues the company had with shipping and miners arriving damaged we got a refund until they resolved the issue. Meanwhile PinIdea has already announced a new X11 ASIC miner called DR-2 that will be a redesigned and improved DR-1 offering 600 MHS of hashrate at 335W of power usage in a smaller and more silent enclosure. The catch is that the new miner will be available in August and that is quite some time from now and we are probably going to wait for this one to get it for a detailed review.
