While still in pre-order stage the first 7nm ASIC miner for Bitcoin (SHA256) – the 24 THS GMO B2 miner has been sold out. The Japanese company behind the project however is apparently ready with a successor – the GMO miner B3 that will be offering variable hashrate of 24-33 THS with 1950-3417 Watts of power usage respectively at the same price of 1999 USD. The new miners will come with 180 days of warranty and the price includes a 4 kW power supply as well. GMO is already taking pre-orders for the new B3 miners and you can pay using Bitcoin, Bitcoin Cash or USD with shipping expected to start in November 2018.

The new GMO B3 ASIc miners come with the same base specifications, but there is an extra that allows the device to either automatically adjust performance or the user to optimize it so that it can reach up to 33 THS hashrate with reduced power efficiency. This feature is interesting as it will allow miners to increase performance at times when there is higher profit to be made and to reduce it when the profit is not that good. The extra performance at the same price as that of the original B2 miners does seem like an interesting upgrade, especially considering that you get an adequate power supply also included in the price.

If you are interested in learning more details about the upcoming GMO B3 ASIC miners…

RebTech is a Romanian company that you may never heard of, but they do offer some interesting GPU mining related products that you might be interested in checking out. We are mostly interested in the RebTech Blockchain Motherboard that and the RebTech Blockchain Video Card as both products are certainly interesting in their design and functionality and are clearly made with GPU miners in mind. The company also seems to be building what they call Blockchain mining servers based on these two products they offer, so you might be interested in these as well. But first let us take a look at the Blockchain motherboard and video card and why they are so interesting…

The RebTech USB-VGA AMD Radeon RX470 8GB video card may seem like a traditional RX 470 GPU, but it is not, it is designed specifically for use for GPU mining (Ethereum in particular as a focus). These GPUs do come with a built-in PCI-E extender via USB transfer cable with direct USB connector onboard instead of a traditional PCI-E slot. They use a specific mounting plane and the lack of a traditional x16 PCI-E slot on the board allows for some clever new ways of mounting the GPUs. Even though they are apparently designed to be used for mining these video cards still do feature a single HDMI video output, so that you can connect a display. Now we would love to see similar designs with more powerful AMD GPUs as well as with Nvidia GPUS…

The RebTech 8GPU-MB mining motherboard is what is more interesting here as it offers an all-in-one solution with everything you need to setup up to 8x GPU mining rig with it. The motherboard comes with AMD A6-8500 CPU with integrated GPU, 4G DDR3 RAM, 120G MSATA SSD and features 8x USB/PCI-E extenders on board. The whole thing is similar in size and in form factor to a GPU and you can apparently mount it just like another video card in your mining configuration. What makes it even more interesting is the fact that the motherboard is powered with 12V only via a single 6-pin PCI-E power connector, again just like a video card. This means that you can go with a cheaper and more efficient server-type power supply that only outputs 12V, similar to what most popular ASIC miners go along with.

Both the RebTech Blockchain Motherboard and the Blockchain Video Cards are interesting products for miners, especially for those interested into larger scale operations as the products do offer some interesting and very useful advantages. The only thing that worries us a bit here is that although the company claims to be in the mining business since 2012 their website is just two months old…

Canaan’s Avalon ASIC miners do not seem to be getting much attention unlike Bitmain’s for example, but that doesn’t mean they do not have something new and interesting to show from time to time. Their latest creation Canaan Moose is an integrated Bitcoin ASIC miner solution that offers 156 THS SHA256 hashrate for BTC mining in a single package that is ready to be plugged in and start mining. The miner is based on twelve Avalon 841 that consume a total of 15480 Watts of power and the miner needs three phase power in the from of two IEC 60309 16A power connectors.

Canaan Moose Specifications:
– Hashrate: 156TH/s, -5% ~ +10% : Average 163.2
– Power Consumption: 15480W, +0% ~ +20% @ 13TH/s, 25°C, 93% PSU Efficiency, 12V AC, Wall-Plug
– Power Efficiency: 0.099J / GigaHash Wall-Plug
– Power Connectors: IEC 60309 16A x 2
– Rated Input Voltage: 365 ~ 418V
– Frequency: Smart Speed
– Network Connection: RJ45 Network Connector
– Operating Temperature: -5℃ ~ 30℃
– Air-intake Temperature: -5℃ ~ 30℃
– Dimensions: 890 x 450 x 725 cm
– Net weight: 140kg

The 156 THS Canaan Moose ASIC miner is priced at $9900 USD and comes with everything ready to be used, you just need to plug power and internet and set your mining pool and worker. No need to setup things using 12 separate ASIC miners, everything is ready to go with power supplies, network connectivity and miner control. It even seems to come cheaper than purchasing 12 separate miners, 12 power supplies and a miner controller, so it might be of interest to some larger scale miners as a ready to deploy solution… it is even stackable.
