Canaan Technology, a China-based manufacturer of cryptocurrency mining machines, has launched its new liquid-cooled mining machine A1466I in Singapore. The machine has a hash rate of 170 T and an impressive energy efficiency ratio of 19.5 J/T, making it Canaan’s most efficient machine to date. The A1466I also boasts a price tag of less than $18.88/T, making it an affordable option for miners looking to maximize their profits. This launch marks a significant milestone for Canaan, as it is the company’s first machine with an energy efficiency ratio under 20 J/T.

This is not the best energy efficiency on the market, but maybe the company will offer a better price to compete.
Canna is serious underdog contender.
Yes seen this they announced it in their 10 year anniversary conference.
Price tag seem the best one curently for that efficiency of the miner.

So far I don't believe any of the rumors.

Eagerly waiting to see the specs.

Fire sale on s19 xp incoming

If you're hoarding s9s thinking they will make a come back, you're wrong.

Model Antminer S21 (200Th) from Bitmain mining SHA-256 algorithm with a maximum hashrate of 200Th/s for a power consumption of 3550W.
 Not yet available (First release in March 2024)
Estimates are based on today's values to provide an indication only.
Profitability could change a lot by then.

Yes was there myself also , launch price 14usd per TH/s which seems decent availible till october 7 , downside is minimum order of 6000 machines.
Price goes up for preorder to 19 usd per TH/s after october 7.

I dunno, did no one read the actual numbers on the bigger one?

335T 16J/T = 5.36kW - big number Tongue

And if the miner is offline you lose 335T until you fix it.

This 335T number is just ridiculous - over sized, over powered, just keep throwing more chips at it, miner - purely for marketing a big number, but not at all intelligent.

If I glue 3 of my Watts miners together I get 390TH - wow that would be even higher - lol

The miner who buys 5 kilowatt ASICs probably doesn’t worry about this, because he has a lot of them, not just a few. Such ASICs are even sold in large quantities at the factory, starting from several thousand pieces, and a small miner cannot buy an ASIC at a good price.

...
So, are you advertising that you are selling these miners that violate the cgminer GPLv3 license?

Compared with previous type, which are
  • S19 XP (140Th, 3010W) vs S21 (200Th, 3550)
  • S19 XP Hyd (255Th, 5304W) vs S21 Hyd (335Th, 5360)

S21 series has 1.3x-1.4x more hashrate. But on other hand, overall watt usage has little difference and have same physical size. While i agree with your point about marketing, it looks like they also consider miner who want replace their ASIC without too much change on their side.

P.S. number i mentioned taken from https://www.asicminervalue.com/efficiency/sha-256.
I think soon there will be new firmware for these ASICs that will make their use more interesting for miners. And with the electricity consumption, Bitmain was cleverly thought out so as not to force miners to redo the electrical wiring to install new ASICs.

Actually the 335 hydro is a direct attack against 100kwatt to 1 megawatt miners.

Most of us under 1 megawatt of power have 2 phase 208-240 power.

the hydro is 3 phase 380-415 volt power.

My mine has a 460 volt 3 phase that drops to 208-240 2 phase.

if I want to run one or more of the hydro miners it means buying  a 380-415 three phase step down transformer.

yet another expense.

fast search I found this:

https://www.ato.com/30-kva-isolation-transformer.

I could do 5 units of hydro

cost for me is 5,100 plus shipping and install. and hydro cooling for the gear.

Antminer S21 for the Bitmain company was apparently very expensive, so there is not enough money to pay employees:

Bitmain, a dominant force in the Bitcoin mining hardware industry, announced on October 3 that it would temporarily halt a portion of its September salary disbursements for all its employees.

The decision was attributed to the company’s operational cash flow remaining negative throughout the month.

This development has raised eyebrows within the crypto community, especially as Bitmain remains a major player in the mining landscape. Notably, this announcement came shortly after the company’s recent conference in Hong Kong where it unveiled its advanced S21 mining machine.

The notice circulated internally, which was later verified by certain employees, highlighted the company’s challenges, particularly underscoring that its mining operations hadn’t met expectations. The message from Bitmain’s Executive Management Team (EMT) expressed an urgency to meet specific targets and objectives, commonly referred to within the company as POTA (Goal-oriented, mission).

https://twitter.com/WuBlockchain/status/1710880716383494207

And just a few hours later after:

Quote
On the afternoon of October 7, Bitmain has repaid September wages, and stated that it only did not pay the performance salary of some people. It has also been repaid, and the basic salary has been released normally on September 30.

They have been selling for a year gear at three times the price, charging at one point 8k for an s19, that's probably the last company in the crypto world that would not be able to pay wages. Rather than the development of the S21 I tend to believe it's the unsold stock of miners and not honored deals that are affecting their business and a potential cashflow, they have around 300 people paid directly, what's that, even on above average wages that's less than 1000 miners.

They've moved the date, there is a January batch now available, seems like they really want to test miners' resolve during the halving.

Heck so far we are earning a profit this year.. Not much
my last 8 years
2016 good
2017 great
2018 okay
2019 loss
2020 okay
2021 really really really good
2022 okay
2023 a little ahead and a lot of work

2024 I am willing to take a small loss

I do not like to see the hydro 3 phase liquid gear as I am not looking to convert all my s19xp's to s21 hydros.

Under the spot contract, only 1 ASIC model is available for sale, and it seems to me that their new Antminer S21 ASICs discourage the desire to buy S19k Pro ASICs.
They used to have smaller batches of ASICs for sale.

Buying the January batch doesn’t work for me, but the sale of ASIC S19 will end in January

How much did you buy the ASICs for?

How much did you buy the ASICs for?
In Russia, miners buy a new ASIC S19 90 terahash with 126 chips for $1,000. An ASIC with documents from customs costs $1,250, but this is not necessary for everyone.

Next, this ASIC is flashed into a mode of 110 terahash, 3500 watts and Bitcoin is mined and additionally received NMC,SYS,ELA

Yes love the competition, will be reporting live from this event Smiley
Whatsminer machines are very reliable and stable.
Even same performance as bitmain S21 generation same specs and cheaper price would put them in better position.

Have you seen the new power connector for new Bitmain S21 ASICs?
I hope the cable comes with the ASIC.



Why is Bitmain inventing new connectors? New ASICs have the same power as the old s19 series. If you lose such a cable, you won’t be able to quickly buy it in a store.
