The RX 6900 XT was AMD's flagship of the RDNA 2 generation, released in December 2020 at $999. With 16 GB of GDDR6 and 5,120 stream processors, it lagged NVIDIA on Ethash but pulled ahead on Autolykos2 and certain ASIC-resistant algorithms thanks to AMD's compute architecture.
Post-Merge, the 6900 XT remains a strong pick for Ergo and FishHash mining, and its lower stock TGP (300W vs 350W on the 3090) gives it an efficiency edge at scale. At sub-$0.08/kWh, it's profitable on Kaspa and Ergo.
Is the RX 6900 XT good for mining in 2026?
Yes for Autolykos2 (Ergo) and FishHash (Iron Fish), where its AMD compute architecture excels. For Etchash it lags equivalent NVIDIA cards by 25-40%.
RX 6900 XT vs RTX 3090 for mining?
The 3090 outperforms on Etchash and KHeavyHash. The 6900 XT closes the gap on Autolykos2 and FishHash. At equal used-market prices, the 3090 is generally the safer mining buy.
How many watts does the RX 6900 XT use mining?
Stock TGP is 300W. Most miners undervolt to 180-220W for best Mh/W ratio. Calculator uses 200W by default.
Can AMD GPUs mine the same coins as NVIDIA?
Yes — every GPU-mineable algorithm runs on both vendors. Performance and efficiency vary by algorithm; AMD generally wins on Autolykos2, NVIDIA on Ethash-derived algos.
