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

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).

Bitmain Antminer Z11 Specifications:
– Model No.: 240-Z
– Crypto Algorithm/Coins: EquiHash/Zcash
– Hashrate, KSol/s: 135
– Reference power on wall, Watt: 1418
– Reference power efficiency on wall @25°C, J/Ksol: 10.50
– Adapted AC/DC output requirement, Watt/ Volt: 1729/ 12.00
– Quantity of hash chips: 9
– Quantity of hash boards: 3
– Networking connection mode: RJ45 ethernet 10/100M
– Miner Size (Length*Width*Height, w/o package), mm: 242*134*302
– Net weight, kg: 5.40
– Noise, dBA @ 25°C: 70

Move away Antminer Z9 Mini, Bitmain is starting to sell the “full” Antminer Z9 that will supposedly offer 40000 Sol/s for Equihash mining at 1150W of power usage with deliveries starting at the beginning of September and priced at $3319 USD (PSU is not included). For comparison the already available Antminer Z9 Mini offered just 10000 at about 250W of power usage. On the other hand there is also the Innosilicon A9 ZMaster Equihash ASIC Miner that offers 50 Ksol/s at just 620 Watts of power usage, but at three times higher price and currently out is of stock.

Bitmain is currently showing only a rendering of the new device, not an actual photo, but it seems like two slightly longer Z9 Minis stitched together (maybe an extra chip or to per board). We already know that the chips used in the Z9 Mini are overclocking pretty well, so two Z9 Minis can easily reach 30 KSol/s at maybe about 700 Watts and three overclocked units can go for as much as 45 KSol/s with just about a Kilowatt of power usage. Considering this and the fact that the device apparently only has 7 PCI-E power connectors (6 for ASIC boards and 1 for the control board) we can easily assume that Bitmain may have achieved the high power usage with less chips that are already overclocked quite a lot. If they did do just that the price of the new “more powerful” units may not be justified and you should not be expecting to see a lot of headroom for improving performance like on the Minis.
