Pros & Cons
Bitmain Antminer KS7
- Over 3× the hashrate of the KS5 Pro (70 vs 21 TH/s)
- Dramatically improved kHeavyHash efficiency vs previous generation
- Standard Bitmain form factor — same power and rack infrastructure as S21
- High acquisition cost (~$8,500–$11,000 new)
- Kaspa-only — single-algorithm ASIC with no fallback coin
- High KAS network difficulty growth may compress ROI over time
IceRiver KS5L
- Competitive 20 TH/s kHeavyHash hashrate
- IceRiver-native firmware with straightforward pool setup
- Lower acquisition price than KS5 Pro in some markets
- Less efficient than KS5 Pro (170 vs 150 W/TH)
- Smaller IceRiver support and firmware ecosystem vs Bitmain
- Kaspa-only — no algorithm flexibility
Frequently Asked Questions
