Hashrate by Algorithm
GPU miners can switch algorithms freely. Current performance figures at stock + light power-limit tuning:
| Algorithm — Coin | Hashrate @ Power |
|---|---|
| KAWPOW — Ravencoin (RVN) | ~39 MH/s @ 150 W |
| RandomX — Monero (XMR) | ~7,200 H/s @ 130 W |
| Etchash — Ethereum Classic (ETC) | ~64 MH/s @ 120 W |
| Blake3 — Alephium (ALPH) | ~1.7 GH/s @ 140 W |
Figures are approximate and vary by AIB model, VRAM temperature, and overclocking. Always benchmark your specific card.

Pros & Cons
Pros
- Best watts-per-MH ratio of any mainstream GPU at KAWPOW
- Low acquisition cost (~$350–$450 secondary market)
- 16 GB GDDR6 — future-proof VRAM for growing DAG files
- Quiet at full load compared to high-end NVIDIA cards
Cons
- Lower absolute hashrate than RTX 4090 (39 vs 62 MH/s KAWPOW)
- RDNA2 architecture — older gaming profile affects resale
- AMD firmware tuning requires more effort than NVIDIA for beginners
Frequently Asked Questions
Why is the RX 6800 XT so efficient for mining?
The RX 6800 XT's efficiency comes from AMD's RDNA2 Infinity Cache — a large on-die cache that drastically reduces reliance on the slower GDDR6 memory bus for memory-bound algorithms. At KAWPOW, the 6800 XT achieves ~39 MH/s at ~150 W (3.8 W/MH), outperforming most NVIDIA GPUs on efficiency even if not on raw hashrate.
What is the best mining software for the RX 6800 XT?
TeamRedMiner is the recommended miner for AMD GPUs in 2026, offering optimised kernels for KAWPOW, Etchash, and Blake3. lolMiner is a strong alternative for Etchash and Blake3. For RandomX (Monero), XMRig supports OpenCL for AMD, though RandomX strongly favours CPU architecture — GPU mining XMR with the 6800 XT is viable but not optimal.
How do I overclock the RX 6800 XT for mining?
Use AMD Adrenalin Software or MorePowerTool (MPT) for overclocking. For KAWPOW: set memory clock to +50–+100 MHz from stock, reduce core clock to 1,100–1,300 MHz, and set power limit to 70–80%. KAWPOW is memory-bandwidth bound — prioritise memory clock first. Start conservative and increase memory clock in 25 MHz increments until hashrate plateaus or instability appears.
Is the RX 6800 XT worth buying for mining in 2026?
At secondary-market prices of $350–$450, the 6800 XT offers excellent mining value. Its efficiency advantage keeps operating costs low, and 16 GB VRAM ensures compatibility with growing DAG sizes for years to come. The RDNA2 architecture also retains gaming utility (well-supported drivers), which improves resale value if mining profitability declines.
