Bitmain's New S21 XP 13.5J/T 270T

The S21 XP looks like some wild air cooling tech, hitting 270TH/s. Stay tuned for more info coming soon.

pretty insane efficiency.

13.5 watts is impressive any links to see announcement?

Yep! https://theminermag.com/news/2024-06-17/bitmain-antminer-s21xp-bitcoin-mining-efficiency/ https://x.com/hashrateindex/status/1802820360548839524

That is a brutal hit to all 24watt and above gear. And they want 50 usd a th that is 13500 . At 6 cents a th and free power 50.00/.06= 833 days to break even. If you have 6 cent power it burns 5 bucks a day which adds 33% more time So break even for a six cent miner is about 1150 days

Do note that those specs are for the immersion or hydro cooled miners. If they also do an air-cooled version the fans will be drawing around 125w or more so eff will take a hit. per https://x.com/hashrateindex/status/1802820360548839524

You'll find screenshots from the event of an Aircooled unit at those numbers   My guess is Bitmain still has those 234 TH units to sell and they jumped the gun. I'll be on the sidelines until their official release. https://youtu.be/i7sEaMKfIx8?si=oqG5Ov5ZGAXu0C3_

And then they also announce even lower power miners for the same time frame... https://ir.bitdeer.com/news-releases/news-release-details/bitdeer-unveils-sealminer-technology-roadmap-committed-enhancing Aren't they rather shooting themselves in the foot?

At times they do weird sale moves. Right now no one needs gear. So to think buying a piece of gear for 13500 that earns under 20 usd a day makes any sense I wish them luck.
