Bitcoin ASIC Miners Still Hard to Get for Small Miners

28, Jan 2018

If you are a small crypto miner and not a large mining operation you may find it very hard to acquire up to date Bitcoin ASIC miners as the demand is still pretty high and the wait time is long. If you manage to find an ASIC miner is stock the chances are the price will be significantly higher as they are being resold with serious profit by people that prefer to make money this way instead of mining with the devices. At the moment there are pretty much 4 main manufacturers of Bitcoin ASIC miners that sell to end users and in small quantities and as you might expect they do not have anything in stock as the wait time is in months.

1. Bitmain AntMiner S9 (13.5 THS)
Bitmain is the most popular name among the ASIC manufacturers and probably the biggest one as well and even they are struggling to have stock of the AntMiner S9 ASIC miners they produce. It is interesting to note that the S9 has started shipping in the summer of 2016 and is still their top product. Bitmain has already sold all of their production up until the end of March, so when they release a new batch it will be scheduled for delivery sometime in April earliest.

2. Canaan AvalonMiner 821 (11 THS)
Canaan has been making their Avalon miners for years, though they were a bit slower in terms of specifications as compared to Bitmain and not as popular among end user miners. Their latest AvalonMiner 821 was announced in December last year and just started shipping its first batches for people that have preordered early. You can currently preorder AvalonMiner 821 for shipping/delivery in the second half of March, so you can probably get these a bit earlier than if you wait to preorder an AntMiner.

3. Ebang Ebit Miner E10 (18 THS)
Ebang’s Ebit miners are mostly popular in Asian countries, though they are trying to get to a wider market and their latest announcement of a 10 nm ASIC miner – the E10 made some waves. It is however an expensive device and still hard to get with a minimum purchase quantity of 20 units and all batches already sold through the end of March.

4. Halong Mining DragonMint 16T Miner (16 THS)
Halong Mining is a newcomer that just recently announced their plans to enter the Bitcoin ASIC miner market to try and fight with the market dominance that BitMain already has. They are still yet to start shipping their first devices in March this year and you cannot currently preorder units on their website with new batches probably to be available for April earliest.

Bitmain AntMiner R4 is Supposed to Bring Mining Back Home

26, Aug 2016

antminer-r4-1

Bitmain is apparently setting a very ambitious goal of their new miner called AntMiner R4 and that goal is to bring back home mining of Bitcoin. What they are doing in order to get home miners’ attention is trying to make the miner more compact and less noisy while still managing to provide quite a serious hashrate rated at 8.6 THS with just about 845 W of power usage. What will make the most difference for home users however is the price of the new miner and if it is not right, then why would you bring one or even more of these home, guess we’ll know in a few days as sales start at 23:00 (GMT+8) on 29 August when we’ll probably also get an idea about the price of the device.


Bitmain AntMiner R4 Specifications:

– Miner Hash Rate: 8.6TH/s (Variation of ±5% is expected)
– Power Consumption: 845W +9% at the wall (with Bitmain APW5 PSU)
– Power Efficiency: 0.1 J/GH +9% at the wall (with Bitmain APW5 PSU)
– Noise level: 52dB (at an ambient temperature of 35°C)
– Chip quantity per unit: 126 x BM1387
– Default Frequency: 600MHz
– Rated Voltage: 11.60 ~13.00V
– Network Connection: Ethernet
– Operating Temperature: 0°C to 40°C
– Product size: 515mm (L) x 100mm (W) x 222mm (H)

antminer-r4-2

One of the most interesting things that you will notice with this miner is the cooling fan it uses, Bitmain calls is “a groundbreaking custom-design fan” that is intended to reduce the noise coming from the miner. Instead of using traditional computer fans (designed for servers) that are not intended to be silent, but instead to do their job providing good cooling they have opted out for a different design for the R4’s cooling. The fan that Bitmain uses in the AntMiner R4 is apparently inspired by the fan of a silent split air conditioner, so it was designed to make less than half the noise of the standard miner fan. Furthermore the rotational speed is being automatically controlled to ensure it never creates more noise than is absolutely necessary to keep the miner cool and running, so the noise will also depend on the ambient temperature.

bitmain-apw5

Bitmain will be also offering an optional custom-built PSU for further noise reduction to go along with the AntMiner R4 – the Bitmain APW5. The power supply works with both 220V and 110V (the standard in North America) input to deliver 2600W and 1300W, respectively. It has a dynamically controlled fan that runs at full speed only after heat sink temperature is 80°C. The Bitmain APW5 should start selling along with the Antmier R4 miner in a couple of days, do note that this is a 12V only power supply that is capable of delivering a very good efficiency of up to 93%. So it may be a great choice to go along with the R4, unless of course you already have some spare 1 KW or more computer power supplies sitting idle.

ZeusMiner Partnering With Rockminer to Offer Bitcoin ASICs

23, Sep 2014

zeusminer-rockminer-partnership

ZeusMiner is making ASIC Scrypt miners, however it seems that the company is also interested in offering Bitcoin mining hardware as well and as a result they have announced a partnership with a well-established brand in BTC mining – Rockminer. As a result of this partnership between the two companies you can purchase the 800 GHS Rockminer T1 ASIC miner at a price of just $369 USD, a nice deal if you are looking to invest in SHA-256 mining hardware. The Rockminer T1 is rated to provide 780-840 GHS hashrate with a power usage of about 1000 Watts, do note that the miner does not come with a PSU included, so you will need to buy it separately and unfortunately this adds extra cost if you don’t yet have a powerful PSU available. Do note that ZeusMiner does ship from China, it is not yet clear if the distributors of Zeus will also be offering Rockchip miners and if the price will be as good.
