550 MHS BW-L21 Litecoin (Scrypt) ASIC Miner

28, Aug 2017

The recent return of interest in Litecoin (LTC) and the growing price has apparently also sparked interest for more up to date ASIC miners and there is one more contender now available apparently. Here comes the BW-L21 Litecoin (Scrypt) ASIC Miner from BW.com promising to deliver up to 550 MHs with 950W of power usage. The ordering process for these devices however is not that easy apparently, there is a minimum order quantity of 100 units and the price is about 2500 USD. You need to contact BW by email in order to arange an order and make the purchase, though with 100 units MOQ this is hardly interesting for small home miners. Bitmain’s AntMiner L3+ Scrypt ASIC miner is still much more attractive to small miners that want to get just one or a couple of units, that is if you manage to buy one when new batches are being released.

BW.com BW-L21 Specifications:
– Hash rate: 550 MHS +/- 10%
– Power consumption: 950 W +/- 10%
– Power efficiency: 1.727 J / MHS
– DC voltage input: 12 VDC +/- 5%
– ASIC chip type: 28nm LTC ASIC chip by BW.com
– ASIC chip quantity per unit (miner): 144 chips
– Number of hash boards per unit: 4 hash boards
– Cooling: 2x 120mm x 38mm fan, 3000rpm (front and back, in a push-pull configuration).
– Weight: 4.8 kg
– Dimensions: 329mm (L) x 127mm (W) x 159mm (H)

Bitmain to Launch New AntMiner L3+ Scrypt ASIC

11, Apr 2017

The crypto currency mining ASIC maker Bitmain is getting ready to launch a new Scrypt ASIC miner with shipping expected to start a bit later this month. The new device capable of mining Litecoin (LTC) and other Scrypt-based crypto currencies is called AntMiner L3+ and should be capable of delivering a hashrate of 504 MHS with a power usage of 800W. With the recent jump in interest and the price of Litecoin we are seeing a bit of a revival of the interest in Scrypt-based coins and this is apparently also the reason why Bitmain has prepared a new more powerful device.

The new Antminer L3+ is essentially double the performance and power usage of the regular AntMiner L3 model announced earlier this year. It offers essentially doubled performance by doubling the number of BM1485 ASIC chips from the 144 units in the L3 to 288 in the new L3+. The English website of Bitmain still hasn’t got the product listed, but their Chinese one has the device already listed with a price of 1.686 BTC per L3+ device that does not include a power supply. The shipping should start sometime in between April 15th and April 20th based on the data on the website. Early May deliveries (May 1st – May 10th) are also possible with a lower price of 1.261 BTC per L3+ device.

Bitmain AntMiner L3+ Scrypt ASIC Specifications:
– Scrypt mining hashrate: 504 MHS
– Power consumption: 800W ± 10% (at the wall, with Bitmain’s APW3-1600 PSU, 93% efficiency, 25°C ambient temperature))
– Power efficiency: 1.6J/MH ± 10% (at the wall, AC / DC efficiency of 93%, 25°C ambient temperature)
– Rated voltage: 11.6 ~ 13.0V
– Chip Type: BM1485
– Chip quantity per unit: 288 chips
– Number of boards in the whole machine: 4 pcs
– External dimensions: 352 mm (L) * 130 mm (W) * 187.5 mm (H)
– Machine weight (without packaging): 4.4kg
– Operating temperature: 0°C to 40°C
– Operating Humidity: 5% RH-95% RH, non-condensing
– Network connection: Ethernet
– Noise level: 75dB

Bitmain Getting Ready to Launch the Antminer L3 Scrypt ASIC Miner

19, Jan 2017

Another interesting piece of information about the popular ASIC manufacturer Bitmain as apparently the company is planning to launch their first Antminer L3 Scrypt Miner. Some of you might remember that back in 2014 Bitmain was planning to launch Antminer L1 Sctypt ASIC miner, but that one never came into existence. Apparently back then the company reached a stage that allowed even without launching a product to continue working and get an even more efficient solution and here comes the L3. There is some information available about the device already, even though it is not yet officially listed on the English website of Bitmain (you can find a product page on the Chinese one).

You can find some photos and even some early performance results online from peopel that managed to get some early units apparently, including a tweet from charlie Lee who created Litecoin (LTC) about getting one of these devices. More general availability is expected sometimes in February probably because of the incoming Chinese New Year, so we are going to have to wait some more time. What is the most interesting thing about the Bitmain AntMiner L3 Scrypt ASIC miner is the efficiency that the device not only apparently promises, but also delivers – 250 MHS hashrate with just 400 Watt power usage. This makes is significantly more power efficient compared to its only competitor with a recent generation of Scrypt ASIC hardware available – Innosilicon A4 Dominator (280 MHS at 1000W). The price listed on the product page is 1.825 BTC or a little over $1600 USD at the current exchange rate. Do note that the Antminer L3 ASIC does come without a power supply, but with the power usage the device has it does not require expensive and harder to find power supply, a decent 500W PSU should do just fine.

Bitmain Antminer L3 Specifications:
– Scrypt mining hashrate: 250 MHS
– Power consumption: 400W ± 10% (at the wall, with Bitmain’s APW3-1600 PSU, 93% efficiency, 25°C ambient temperature))
– Power efficiency: 1.6J/MH ± 10% (at the wall, AC / DC efficiency of 93%, 25°C ambient temperature)
– Rated voltage: 11.6 ~ 13.0V
– Chip Type: BM1485
– Chip quantity per unit: 144 chips
– Number of boards in the whole machine: 4 pcs
– External dimensions: 230 mm (L) * 135 mm (W) * 158 mm (H)
– Machine weight (without packaging): 2.5kg
– Operating temperature: 0°C to 40°C
– Operating Humidity: 5% RH-95% RH, non-condensing
– Network connection: Ethernet
– Noise level: 60dB
