BitMain Apparently Releasing 8x GPU AMD and Nvidia Miners in China

13, Sep 2017

It seems that BitMain is willing to extend its presence from just the ASIC mining market as the company is apparently releasing two new devices for miners that are essentially dedicated GPU miners. For now the devices dubbed G1 with 8x GeForce GTX 1060 GPUs and G2 with 8x Radeon RX570 GPUs are only listed on the Chinese website of the company with prices only in CNY. This means that they are most likely targeted initially for the Chinese miners market and may not be sold outside of the country. Inside the server like cases we are expecting to see mining versions of the GPUs being used as this is the way to go with such solutions intended for large scale mining operations and not for small home miners. As one would expect the devices are targeted at Ethereum (ETH) miners with hashrates listed for the Ethash mining algorithm, though you should in theory be able to mine pretty much any other cryptocoin that can be mined with GPU. The first batch of GPU miners from BitMain is apparently for 500 units of each.

BitMain G1 8x GTX 1060 GPUs:
– CPU: Inter Broadwell-u 3215 or 3205
– Memory: 4GB SO-DIMM, DDR3 / L-1600
– Hard disk: 1 x Msata 64G SSD
– Ethernet: 1 x 10M / 100M / 1000Mbps (Intel I210-AT)
– USB interface: 2 x USB 2.0
– Display interface: 1 x HDMI
– Graphics card: 8 x NVIDIA GeForce GTX1060
– Hashrate: ETH Hash Rate: 200MHash ± 10%
– Carton size: 530mm x 320mm x 160mm
– Weight: 12.5Kg (without power)
– Price: 18700 CNY or about $2863 USD

BitMain G2 8x RX 570 GPUs:
– CPU: Inter Skylake-s G3900-LGA1151, PCH-B150
– Memory: 8GB UDIMM, DDR4 -2133
– Hard disk: 1 x 2.5inch Sata 128G SSD
– Ethernet: 1 x 10M / 100M / 1000Mbps (Intel I210-AT)
– USB interface: 2 x USB 3.0
– Display interface: 1 x VGA
– Graphics card: 8 x AMD Radeon RX570, GDDR5
– Hashrate: ETH Hash Rate: 220MHash ± 10%
– Carton size: 555mm x 445mm x 132mm
– Weight: 15Kg (including power)
– Price: 19700 CNY or about $3016 USD

There is no mention of power usage and what power supplies are included in the miners or you need to take care of this on your own. Based on the description of the miners it is possible that the G1 does come without a PSU (there are external PCI-E power connectors on the chassis) while the G2 may actually have one built-in (judging from the photos), but it is not very clear. No information of the GPUs inside are mining edition cards or not, nor what is the amount of video memory of the video cards used 3/6GB for Nvidia or 4/8GB for AMD. These are all things that people interested in GPU miners would really be interested in and currently they are not being listed as details.

New BitMain Antminer D3 ASIC Offering 15 GHS X11 Hashrate

18, Jul 2017

BitMain has released their first X11 ASIC miner for DASH and the initial batch was sold out in no time. It is no wonder as the specifications of the device claim 15 GHS X11 hashrate for 1200W of power usage, essentially killing all other competition currently on the market offering X11 ASIC miners. The price of the BitMain Antminer D3 ASIC is $2699 USD (1.12020985 BTC or 59.30564711 LTC) at the moment, so pretty attractive for the performance you get even with no power supply included in the price. Shipping is supposed to start around 15-25 September according to the latest update from Bitmain. There is not much information or details available as the launch of the new ASIC miner from BitMain was pretty surprising. They were so in a hurry that even the photo of the new miner on the official website is actually that of an L3+…

Specifications of the Antminer D3:
– Hash rate: 15 GH/s X11 (Variation of ±5% is expected)
– Power consumption: 1200W (at the wall, with Bitmain’s APW3 PSU, 93% efficiency, 25°C ambient temp).
– Dimensions of the miner: 320x130x190 mm

BitMain Up for Another Scandal With Antbleed Backdoor

27, Apr 2017

After the recent controversy surrounding BitMain and the alleged use of AsicBoost here comes another scandal for the popular ASIC manufacturer. It seems that the company has introduced a backdoor into the firmware of their Bitcoin mining hardware Antminer that allows it to stop miners remotely. Not that they are doing it or will do it at some point, but the ability to do so and control a very large portion of the global mining hashrate is not something that users want. The backdoor is now publicly called and it seems that all recent S9 hardware is affected, and L3, T9 and R4 series hardware are likely to be affected as well.

What is the Antbleed Backdoor:
The firmware checks-in with a central service randomly every 1 to 11 minutes. Each check-in transmits the Antminer serial number, MAC address and IP address. Bitmain can use this check-in data to cross check against customer sales and delivery records making it personally identifiable. The remote service can then return “false” which will stop the miner from mining.
