Bitmain has announced their new Antminer S19 series of SHA256 Bitcoin ASIC miners, though only specifications for now, no price and availability info. The Antminer S19 has 2 variants, a 95 TH/s and 90 TH/s model, with a power efficiency of 34.5 J/TH and the Antminer S19 Pro has a 110 TH/s and 105 TH/s model, both with a power efficiency of 29.5 J/TH. Both series come with a built-in power supply and are rated at 3250 Watts of power usage at the wall utilizing the new APW12 high-conversion efficiency power supply.

Bitmain is trying to up their game with the Bitcoin halving nearing, though the new ASIC miners will most likely be available for delivery soon before or right after the halving, especially with the current situation in China regarding the coronavirus (covid-19). There are already some numbers regarding the price around $5000 USD per unit for the Pro coming from Hashnest (owned by Bitmain), who already list the 110TH/s Antminer S19 Pro as available for rent, though nothing is yet confirmed as final price for the units that will go for sale and when hey will be available for delivery. Anyway, still good to see that BTC ASIC miners’ efficiency can be further improved with optimizations and new technology…

Canaan Creative has announced heir second generation 7nm AvalonMiner ASIC – the A10 that should be capable of delivering 31 THS SHA256 hashrate with 1736W of power usage (56 W/THS energy efficiency). The 30 THS efficiency with 1700 Watts of power usage was supposed to be delivered last year with the announcement of the first 7nm ASIC miner – the Canaan Avalon A9, however the first generation 7nm hardware was not able to deliver what was promised. Not to mention it came at a bad time for the mining and crypto in general – a declining profit and the whole crypto market going down, so the demand for the new devices was really low. Instead of 30 THS, the AvalonMiner A921 was only capable of delivering 20 THS at 1700W of power usage, so the new 2nd gen A10 devices should finally be able to deliver that level of power efficiency. No word yet on pricing and exact availability dates, the official website still does not list the new devices and Canaan is talking about March availability and they just made the announcement at the end of the month, so we should wait a bit more for additional details…

It seems that the ASIC miner market is waking up for the new generation of devices even with a market situation where profitability is still not that good as more ASIC manufacturers are announcing their new products. MicroBT, a Chinese manufacturer that is not very popular like Bitmain outside of Asia apparently, has is soon releasing their new generation M20 SHA256 ASIC miners for Bitcoin and other crypto currensies with the same algorithm and it resellers are already taking pre-orders for July delivery. Even though the official MicroBT website still has no info (to be officially unveiled on April 15th?), some of the partners such as Pangolin Miner and WhatsMiner Net have already listed for pre-order the new M20 ASIC in what seems to be 3 different configurations…

The MicroBT WhatsMiner M20 is a 12nm ASIC Bitcoin SHA256 miner with integrated power supply ad available in a M20V1 version with 48 THS hashrate with 2200W power usage (46W/Th) and 2500W integrated PSU available for $1450 USD, an M20V2 version with 58 THS hashrate with 3364W power usage (58W/TH) priced at about $1500 USD and M20S model with 72 THS with 3312W of power usage (46W/Th) available for $2160 USD. The provided integrated power supplies are apparently only 220V, so this could be a problem for use in some countries where different voltage for the power is being used such as USA!

Looking at the specifications it seems that the M20V2 version is most likely an overclocked variant of the V1 as it delivers higher hashrate, about 10 THS more, but at higher power consumption and worse efficiency. Thus the price difference between the two devices is not that big as most likely only the PSU is changed with a more powerful model in order to be able to handle the extra power usage. The top model M20S with 72THS has the same power efficiency as the standard M20V1, so apparently it has more chips running at the same operating frequencies and voltage as on the smallest model, however any additional significant overclock of this model may not be possible as the power supply shipped with the device may be already close to its maximum specs.
