Samsung has started production of 3-nanometer microchips. This technological advancement will allow CO2 emissions to be reduced from the mining of bitcoins.
And for a billionth of a meter less
Korean Samsung has started production of 3nm chip. The Korean firm claims that the new incineration process is 45% more efficient in terms of energy consumption.
3 nm chip performance is reported to be 23% higher. Samsung is even talking about 30% with the second generation of 3 nm chips.
Better yet, the South Korean group will tackle 2 nm chips by 2025. This is a good sign of the energy efficiency of the mining of bitcoins. The latter quantifies the performance of the machine mining. The efficiency ratio is generally calculated as follows:
Energy Efficiency = Watts / Terahash
- Watts indicates electricity consumption
- The terahash indicates the number of hashes
The lower this ratio, the more efficient the machine. For example, the Whatsminer M20S (2019) consumes 3,360 Watts per hour and generates 68 TH per second. So its energy efficiency ratio is:
3360 Watts / 68 Terahash = 49
By comparison, Bitmain’s first antminer U1 (2013) energy efficiency was 1250. Worse, the ratio of average PC processors used during the beginning of Bitcoin (2009) was 877,000 yen
The best ASIC currently on the market is definitely the S19X antminer which uses a 5nm chip. The energy efficiency ratio is 21. That’s a 58-fold increase in energy efficiency in just eight years.
We say “definitely” because the manufacturers do not reveal what kind of chips they use.
Here is an estimate that makes the site excellent every day for comparison:
Bitcoin is decarbonising
The BMC (Bitcoin Mining Council) predicted at the end of the first quarter of 2022 that efficiency will increase sixfold in the next eight years. Samsung’s new chip already promises an energy efficiency ratio of about 15.
We will have two too half over the next six years. That is, the remuneration offered to BTC miners will be divided by four. This reduction in rewards will force less efficient miners to throw in the towel.
It is clear that miners with free electricity will be able to survive as long as their engines are in working order. But it is essential on the one hand that the juice is renewable, and on the other hand that no one wants some. This is the case near hydroelectric dams.
In short, third – generation miners (before S9) who pay electricity above one or two cents per kilowatt hour will no longer be profitable. These miners need to be shut down, which will reduce the overall energy consumption of the Bitcoin network.
Overall, improving electronic chips, temperature control software, techniques of coolingetc., and the half pledge under 24 share of the energy consumption of the Bitcoin network.
In concrete terms, the value of BTC would have to increase 24 times over the next eight years to increase the network’s energy consumption.
Meanwhile, the Bitcoin network was consuming 25% less energy at the end of the first quarter than a year earlier. This trend will continue until the value of BTC is high enough to attract new miners to join the network.
So far, miners have more into disconnected machines because of the bear market. Some businesses of mining They are even forced to sell a large portion of their bitcoins to pay off the debt, not to mention the depreciation of the machines.
According to data from Coinwarz, the hashratefell, still at 292 PE / s on June 8, to 161 PE / s on Thursday, July 14. We are at their lowest level since February.
Bitcoin miners are being pushed by the energy crisis and the decline of bitcoin. Those who did not want to look for carbon – free electricity tend to sell their BTC, which puts downward pressure on BTC / USD at its worst. To reflect.
