Bitmain has just announced two new Bitcoin ASIC miners with improved power efficiency and hashrate – Antminer S17+ and T17+ at the World Digital Mining Summit (WDMS) in Frankfurt today. The Antminer S17+ has a hash rate of 73 TH/s and operates with a power efficiency of 40 J/TH + 10%, while the T17+ offers a hash rate of 64 TH/s and a power efficiency of 50 J/TH + 10%. The Antminer S17+ and T17+ ​will be available for sale on Bitmain’s official website according to the following timing: pre-sales starting on 11 October 2019, 19:00 GMT+8 and deliveries starting sometime in the 01- 10 December 2019 timeframe. Pricing has not yet been revealed as well as detailed specifications, but they should become clear when the devices are listed for sale in 2 days time. The currently available Bitmain Antminer S17 is 53 TH/s hashrate with 45 J/TH efficiency (2385W) priced at $2322 USD for the next batch and the Bitmain Antminer T17 is 40 TH/s hashrate with 55 J/TH efficiency (2090W) priced at $951 USD for the next batch.

By using dual tube heat dissipation technology, the miners have been designed so that the space between the air inlet to the air outlet has been reduced by 50%, improving heat dissipation effectively as well as reducing fan noise. Besides, a high temperature and fan abnormal protection mechanism has been built in to ensure the stable and safe operation of the miners. Both Antminer S17+ and T17+ use the industry leading Exposed Die package solution and an optimized all-in-one design, making the models easily to be implemented and can adapt to mining farms of different sizes.

Bitmain may not have a stock of their newer 7nm chips for the faster SHA256 ASIC miners, but they apparently have more of the old chips to push new miners, so hence the Antminer S9 SE is born. It is a 16 THS Bitcoin ASIC miner with built-in power supply(?) and a 1280W power consumption (80 J/TH power efficiency). The price of the new Bitmain Antminer S9 SE ASIC miner is set at $351 USD with the first batch to go on sale today scheduled for shipping in 21-31 July, 2019.

Although this may be far from the latest offerings in terms of hashrate, miners like the “new” Antminer S9 SE might be interesting for some people due to their low price and if they can be combined with low priced power it might be a good opportunity. The used market for Antminer S9 ASICs is booming lately due to the price of Bitcoin going up, so we see demand for the new miner for sure. Of course it also depends on the amount of units that Bitmain can deliver…

Efudd’s modified firmware for the Bitmain AntMiner Z series ASIC miners now supports the Bitmain AntMiner Z11 with its latest update to version 2.3, AntMiner Z9 is supported by version 2.2 and for the AntMiner Z9-Mini you need to use the version 2.1d. The modified firmware allows for more advanced overclock including frequency and voltage tuning with voltage controls per hashboard option available. With the modified firmware it is easier to achieve higher performance than with the stock firmware that has limited OC capabilities by Bitmain. According to the developer of the modified firmware 150+ KSol/s (up from the stock 135 KSol/s) should be doable with minimal tuning and further increase to 170-180 KSol/s might be achievable with more power, careful tuning, good cooling and some luck.

Do note that the modified firmware comes with a built-in 3% developer fee, so the miner will be mining for the developer 10 minutes out of every 330 minutes it is operating.
