The world of cryptocurrency mining is highly competitive, and staying ahead requires powerful, efficient hardware. The Bitmain Asic AntMiner KS3, launched in August 2023, has emerged as one of the most advanced mining rigs tailored specifically for Kaspa (KAS) mining. With a hash rate of 8.3 terahashes per second (Th/s) and an impressive power efficiency of 0.384 joules per gigahash (J/Gh), this ASIC miner is engineered for high performance and profitability. In this comprehensive review, we’ll explore its specifications, performance, potential earnings, and key considerations for miners looking to invest.
What Is the Asic AntMiner KS3?
The Asic AntMiner KS3 is a specialized mining device developed by Bitmain to mine cryptocurrencies using the KHeavyHash algorithm—specifically designed for the Kaspa blockchain. Unlike general-purpose GPUs, ASICs like the KS3 are built for maximum efficiency on a single algorithm, making them significantly faster and more power-efficient than traditional mining setups.
While the physical design remains consistent with Bitmain’s standard industrial aesthetic, the KS3 stands out due to its exceptional processing power and energy efficiency. It weighs approximately 16.1 kg and measures 195 x 290 x 430 mm, slightly larger than previous models. The unit operates at 75 dB, which is relatively loud—something to consider for home-based mining operations.

What Cryptocurrency Can the AntMiner KS3 Mine?
Currently, the AntMiner KS3 can only mine Kaspa (KAS). It is purpose-built for the KHeavyHash algorithm and does not support alternative coins. This single-coin limitation increases investment risk—if Kaspa’s value drops significantly or development stalls, the resale value of the miner could plummet.
However, Kaspa's unique block-lattice structure and ultra-fast block times (every second) make it an attractive long-term project for many in the crypto community. For dedicated miners focused on KAS, the KS3 offers unmatched performance.
Understanding the KHeavyHash Algorithm
The KHeavyHash algorithm is a modified version of Heavy Hash that leverages dual Keccak hash functions—a core component of SHA-3 cryptography. This design allows for parallel processing across multiple GPU or ASIC cores, enhancing mining throughput while maintaining security.
KHeavyHash was created specifically to resist centralization by being memory-hard and scalable, though ASIC dominance inevitably shifts the balance toward industrial mining operations. The AntMiner KS3 capitalizes on this by delivering optimized circuitry that maximizes hash output per watt consumed.
Compared to GPU mining—such as using an RTX 3070 achieving around 600 MH/s at 90W—the KS3 is equivalent to roughly 14,000 RTX 3070 GPUs in raw hashing power. This staggering difference underscores why ASICs dominate profitable mining operations.
Performance and Energy Efficiency
The KS3 achieves a remarkable energy efficiency of 0.384 J/Gh, placing it among the most efficient ASIC miners in its class. At full load (3,188W), it consumes approximately 76.5 kWh per day. Assuming an electricity cost of $0.12 per kWh, daily power expenses amount to about **$9.18, or $275 monthly**.
Given current network conditions and Kaspa’s market price, the KS3 generates roughly:
- 98,755 KAS per day (~$2,400 USD, pre-electricity)
- ~$72,000 in monthly revenue (before costs)
With an estimated retail price around $36,000, this suggests a potential return on investment (ROI) within one month under ideal conditions. However, profitability depends heavily on several dynamic factors.
Factors Affecting Profitability
- Network Difficulty (Diff): As more miners join the network, difficulty increases, reducing individual rewards.
- KAS Market Price: A drop in KAS value directly impacts revenue.
- Electricity Costs: High energy rates can significantly reduce net profits.
- Competition: Newer models or mass adoption of competing ASICs (like IceRiver) may saturate the market.
For example, if 5,000 KS3 units enter circulation, daily earnings could fall from $2,400 to around $100 per unit—extending ROI to nearly 500 days. Always use updated calculators like hashrate.no to model real-time projections.
