Bitmain Releases Antminer X9: The First ASIC for Monero, Not Bitcoin
In July 2026, Bitmain begins shipping the Antminer X9, a specialized ASIC miner built for the RandomX algorithm used by Monero (XMR), not the SHA-256 algorithm used by Bitcoin. This is an important distinction: despite the naming similarity to the S-series, the X9 has nothing to do with BTC mining and neither replaces nor complements the Antminer S21 lineup.
Technical Specifications
The Antminer X9 delivers 1 MH/s (1000 kH/s) on the RandomX algorithm at a power draw of roughly 2472W, translating to an efficiency of about 2.47 J/kH. The unit is cooled by four high-speed fans, weighs around 17.5 kg, and operates at a noise level of 75-76 dB. Pricing starts at $5,600 per unit.
According to Bitmain, the X9 uses custom RISC-V cores specifically optimized for RandomX computation. The device's release is also being discussed in the Monero project's GitHub repository, since RandomX-based ASICs were long considered technically difficult given the algorithm's design, which was originally intended to be ASIC-resistant.
Why This Matters Even for Bitcoin Miners
- Don't confuse it with BTC hardware, the Antminer X9 is useless for Bitcoin mining, it's a narrowly specialized device for a different coin and a different algorithm
- Bitmain is diversifying its lineup, entering the Monero mining market shows that the largest ASIC manufacturer is seeking new revenue sources beyond SHA-256 hardware
- The Monero community's reaction, the arrival of a RandomX ASIC sparked discussion in the community, since the algorithm was originally designed to resist specialized hardware precisely to preserve mining decentralization
What Hardware to Choose for Bitcoin Mining
If you're mining BTC specifically, focus on the current SHA-256 ASIC lineup (Antminer S21 XP, WhatsMiner M60S, Avalon A1566, and similar), not X9 headlines. See our full ASIC ranking by profitability and efficiency in the miner rankings section of our site.
When choosing hardware and a pool, factor in current hashprice (see our hashprice drop breakdown) and compare pool fees, see our detailed guide on how to choose a mining pool in 2026.

Frequently Asked Questions
Can I mine Bitcoin with an Antminer X9?
No. The X9 only works with the RandomX algorithm (Monero and other RandomX-compatible coins). Bitcoin mining requires a SHA-256 ASIC, such as the Antminer S21 XP.
Why did a RandomX ASIC become news?
The RandomX algorithm was originally designed to resist specialized hardware precisely to keep Monero mining accessible on ordinary CPUs. The arrival of a commercial ASIC calls that resistance into question.
How much does the Antminer X9 cost?
Pricing starts at $5,600 per unit, with shipments beginning in July 2026.
