Braiins Head of Hardware continues reviewing new Bitmain products. Below, we take a deep look at the T21 190TH, released alongside the S21 200TH in January 2024.
We recently reviewed the Antminer S21, viewing it as a better, stronger, and more efficient brother to the S19, but what about its cousin, the Antminer T21? Why has the S21 taken such a big lead in market share over the T21? To be honest, we can’t truly say.
The common theme here is the striking similarities between the S21 and T21 – in design, firmware, and performance.The biggest differences we’ve seen are in cost and availability – NOT performance. The T21 has a lower cost and higher availability but is about 5% less powerful (in TH) than the S21.
Note: this article contains frequent comparisons between the T21 to the S21. They were released simultaneously, so it only makes sense.
The T21, frankly, has been overshadowed by the flashier S21. The T21 also has twice the hashrate as its predecessor, but is receiving much less attention in the market.
So, what is so different about it? Find out below.
SUMMARY: Bitmain knows what works. They have an established recipe for success when it comes to their hardware – they didn’t need to change much.
SUMMARY: Again, similar to the S21, the inside of the T21 is centered on cooling. The T21 will also thrive at higher temperatures.
SUMMARY: With great chips comes great heat. With great heat, comes great heat dissipation. The T21 has you covered there.
The T21 has the same hashboard – just a different model name – as the S21. It has the same chips, and the same number of chips as the S21. Do they come from a different bin of chips? If they are so similar, why is there still so much availability in T21 units compared to S21 units?
From what our analysts saw, the biggest difference is in the 3 phase PSU, which has higher power capabilities, which means the miner can use more electricity (read: higher overclocking). Like we mentioned earlier, the higher voltage will allow the T21 to overclock much easier than other models. For miners who like to dial things up, this machine is for you.
So, the T21 has incredibly similar specs to the S21, but better availability and lower price. All in all, considering specs, market conditions, and power capabilities, the T21 is a terrific option for miners who prefer overclocking during a bull run.
