Mining Calculator Bitmain Antminer T19 Hydro 158Th

The Antminer T19 Hydro is a glimpse into the recent past, one of Bitmain’s first steps towards the mass adoption of liquid cooling. At its release in late 2022, a hash rate of 158 TH/s was a significant achievement. This machine was created as a more affordable alternative to the flagship S-series, offering industrial miners the opportunity to enter the world of “quiet” and stable hydro mining. It was designed for dense installation in specialized racks, where its low noise level of 40 dB became a decisive advantage.

But time is unforgiving, especially in mining, and the Achilles’ heel of the T19 Hydro is its energy efficiency. Its 5451 W appetite translates into a dismal figure by today’s standards – almost 34.5 J/Th. This is more than twice as bad as modern flagships. Amidst the increasing network difficulty and reduced block rewards after halving, such voraciousness turns potential profit into electricity expenses. This miner requires access to a very, very cheap outlet to stay in the black.

However, it would be hasty to write off the T19 Hydro. Its main advantage – hydro cooling – is still there. It operates quieter than any office printer, opening up possibilities for placement in locations absolutely unsuitable for roaring air-cooled models. Additionally, the liquid system ensures excellent operational stability and a gentler temperature regime for the chips, theoretically extending their service life. Like any “hydro,” it requires external infrastructure for liquid cooling, making it a tool exclusively for prepared sites.

In summary, the Antminer T19 Hydro is a powerful but uneconomical veteran. Its place today is on farms with almost zero electricity cost or where its colossal heat generation can be effectively utilized. For most operators who count every cent per kilowatt, it has already lost the efficiency race to younger and more technologically advanced competitors. It is an interesting artifact from the era of transition to “water” cooling, but not an optimal investment choice in 2024.
