What does the Antminer S21 do?

Bitmain makes more Bitcoin mining gear than any other company in the world, and the Antminer S21 is their newest Bitcoin mining ASIC. There will be two types of cooling for the Antminer S21: air-cooled and hydro-cooled.

A Bitmain official said that the company plans to make at least 50,000 units per month (50/50 air-cooled and water-cooled) for the next eight months. If demand is high enough, the company may make as many as 100,000 units per month.

What is the Hashrate of the Antminer S21?

Antminer S21 has the fastest hashrate of all the ASICs that mine Bitcoin. The air-cooled Antminer S21 is said to have a hashrate of 200 TH/s, while the water-cooled Antminer S21 is said to have a hashrate of 330 TH/s.

As a point of reference, the Antminer S19j XP has the highest hashrate for an air-cooled type right now, with 151 TH/s.

How well does the Antminer S21 work?

The Antminer S21 is the most efficient Bitcoin ASIC miner on the market. The air-cooled model is said to be 17.5 J/TH efficient, while the water-cooled model is 16 J/TH efficient. It is the first Bitcoin ASIC miner to use less than 20 J/TH of power.

The Antminer S19 XP, which had 21.5 J/TH, was the most efficient air-cooled ASIC before this item.

Bitmain plans to start sending out the first Antminer S21 units in December. However, most of its new S21s will be sent out in the first and second quarters of 2024.

As the Antminer S21 hits the resale market over the next few months and years, we expect it to be worth a lot more than older models like the Antminer S19j Pro and a little more than other next-generation rigs like the Antminer S19 XP.

Where can I get an Antminer S21?

Now that Bitmain is taking pre-orders for the Antminer S21, but only miners who can buy a lot of them can do so.

The Antminer S21 can now be preordered at Apexto Store. The first sales of the new ASIC miner are expected to happen between January and June 2024.
