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 KS5 Pro
- Best efficiency in IceRiver's current Kaspa lineup (128 J/TH)
- 25 TH/s — 25% more hashrate than the KS5L at lower power per TH
- IceRiver native firmware with stable pool integration
- Higher acquisition cost than KS5L (~$6,000–$7,500)
- Still trails the Antminer KS7 on total hashrate (25 vs 70 TH/s)
- Kaspa-only hardware — no algorithm flexibility
Frequently Asked Questions
Is the Bitmain Antminer KS7 or IceRiver KS5 Pro more profitable for Kaspa mining?
Based on hashrate-per-watt efficiency, the Bitmain Antminer KS7 is more efficient for Kaspa mining. However, actual profitability depends on your electricity cost, hardware acquisition price, and coin price — use the live calculator for exact numbers.
What is the power consumption difference between the Bitmain Antminer KS7 and IceRiver KS5 Pro?
For Kaspa mining, the Bitmain Antminer KS7 draws 3300 W while the IceRiver KS5 Pro draws 3200 W. The IceRiver KS5 Pro uses 100 W less power, which at $0.07/kWh saves ~$61 per year in electricity.
Can both the Bitmain Antminer KS7 and IceRiver KS5 Pro mine the same coins?
Yes — both units can mine Kaspa (KAS).
Which unit has a better ROI?
ROI depends on hardware acquisition price, electricity cost, and coin price trajectory. The more efficient unit (better J/TH or hashrate per watt) will generally have a lower operating cost per coin mined, but the absolute ROI timeline is determined by the purchase price. Always model both units in the MiningReturns calculator with your specific electricity rate and current market prices.
