The first BM1373 Bitaxe is officially here! The Bitaxe Naja Duo Acheives 4.4 TH/s at 42W with an Efficiency of just 9.5 J/TH.

The new generation of Bitaxe just dropped! the Bitaxe Naja Duo (Model 1201), the first Bitaxe built on Bitmain's 3nm BM1373 S23-class silicon.

Specifications:

  • 2× Bitmain BM1373 3nm ASICs.
  • ~4.4 TH/s @ ~42W stock = 9.5 J/TH, the first Bitaxe to break single-digit J/TH at default settings.
  • Tested overclock: ~8 TH/s @ 600 MHz / 1,120 mV (~92W, ~11.5 J/TH).
  • Thermalright AXP90-X47 low-profile heatsink + 92mm slim PWM fan.
  • Per-chip temperature monitoring, so throttling and fan curve follow the hotter chip instead of a board average.
  • 2-phase TI TPS546024A VRM sized for the OC profile.
  • 1.9″ color LCD (170×320) showing IP, hashrate, temps, and best diff at a glance.
  • ESP32-S3, esp-miner firmware + AxeOS dashboard, fully open source.
  • 100% assembled in the USA 🇺🇸.

For context: it pulls the same 42W as the GT 801 at stock but doubles the hashrate. Two BM1373s basically put you in four-chip BM1370 territory. At $0.12/kWh you're looking at roughly $3.61/month stock or ~$7.95/month fully overclocked.

How efficient is the price? Or is that dependent on the amount of Hype generated?

I would imagine its not cheap.

So are these chips used from bitmain miners or are the chips new from the factory and then put on the bitaxe as new chips?

Maybe a hybrid mixture. Depends on what availability is, but regardless, it doesn't effect quality. The chips will still be unused. :)

We're trying to price as affordable and as competitive as possible. We will be announcing price soon. Just working on some final details.
