It seems that not only Bitmain it getting back in the game with a more powerful Equihash ASIC miner, but Innosilicon also has a new offer for such device. The new Innosilicon Equihash A9++ ZMaster is the successor of their original A9 Zmaster ASIC from last year that offered 50 Ksol/s hashrate for Equihash. The new Innosilicon Equihash A9++ ZMaster comes with 140 Ksol/s hashrate at 1550W of power usage, so efficiency wise it does not seem much better than the original A9 Zmaster – it is almost 3 times faster at almost 3 times the power usage. Innosilicon listed briefly Innosilicon Equihash A9+ ZMaster (with just one plus) with 120 Ksol/s at the same 1550W, but it is not available anymore.

The Innosilicon Equihash A9++ ZMaster is available for order at a price of $1580 USD (without a power supply). It is very similar specifications wise to what Bitmain is offering with their AntMiner Z11, however the A9++ ZMaster could ship faster and be in your hands a bit early. The problem is that unlike Bitmain that caught up with their new product, Innosilicon seems to have just put more of the chips into a bigger device as they were ahead of Bitmain specs wise already with their A9.

Innosilicon Equihash A9++ ZMaster Specifications:
– Hashrate: 140Ksol/s +/-6%
– Power Consumption: 1550W +/-10% (normal mode, at the wall, with 93% efficiency PSU. 25°C temperature)
– Dimensions: 360mm(L)*250mm(W)*155mm(H), dual tube
– Net Weight: 11KG
– Ambient Temperature: 0°C to 40°C
– Network Connection: Ethernet

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.

The new Bitmain Antminer Z11 ASIC offers a hashing power of 135 KSol/s for the Equihash algorithm used by ZCash (ZEC) and other crypto currencies and is essentially the successor of the Antminer Z9 from the last year that offered 40 KSol/s and the Antminer Z9 mini that was just 10 KSol/s. The Antminer Z11 uses Bitmain’s latest proprietary 12nm chip, which is made using advanced Bare Die molding technology for better heat dissipation and has a power-efficiency of 10.50 J/KSol, so it is with significant improvement over the older hardware. The recommended power supply for this miner is 1800W, though the actual like the APW7 PSU from Bitmain, though the actual power consumption is lower (1418 W power consumption claimed). The current price of the Antminer Z11 is $1242 USD and shipping should start around the end of April (20-30).
