Best GPUs for Mining KAWPOW in 2026: Hashrate and Power Efficiency Compared
KAWPOW mining performance depends on more than raw hashrate. A graphics card must also deliver that performance at a reasonable power draw, while offering enough VRAM for the workload and the miner’s preferred configuration. This comparison uses the supplied KAWPOW hashrate, power draw, VRAM, manufacturer, and release-year data for eight GPUs.
The NVIDIA RTX 5090 produces the highest KAWPOW hashrate in the group at 148.5000, but it also has the highest power draw at 420 W. For efficiency, the NVIDIA RTX 5070 Ti leads the ranking, delivering 78.5000 hashrate at 185 W. That makes it an important option for miners who prioritize output per watt rather than maximum performance from a single card.
KAWPOW GPU comparison
The table below presents the supplied specifications without changing the original hashrate or power figures. The efficiency column is calculated as KAWPOW hashrate divided by power draw in watts, so a higher value indicates more hashrate for each watt consumed.

| NVIDIA RTX 5070 Ti | NVIDIA | 2025 | 16 GB | 185 W | 78.5000 | 0.424324 |
| NVIDIA RTX 4080 Super | NVIDIA | 2024 | 16 GB | 205 W | 74.0000 | 0.360976 |
| AMD Radeon RX 7900 XTX | AMD | 2022 | 24 GB | 290 W | 74.0000 | 0.255172 |
| NVIDIA RTX 4080 | NVIDIA | 2022 | 16 GB | 200 W | 71.0000 | 0.355000 |
| AMD Radeon RX 7900 XT | AMD | 2022 | 20 GB | 250 W | 66.0000 | 0.264000 |
Efficiency ranking by hashrate per watt
Efficiency is especially important where electricity is a major operating cost or where a mining rig has limits on total power delivery. The ranking below orders the GPUs by calculated KAWPOW hashrate per watt, from highest to lowest.
| Rank | GPU | KAWPOW hashrate | Power draw | Hashrate per watt |
|---|---|---|---|---|
| 1 | NVIDIA RTX 5070 Ti | 78.5000 | 185 W | 0.424324 |
| 2 | NVIDIA RTX 5080 | 96.0000 | 240 W | 0.400000 |
| 3 | NVIDIA RTX 4080 Super | 74.0000 | 205 W | 0.360976 |
| 4 | NVIDIA RTX 4080 | 71.0000 | 200 W | 0.355000 |
| 5 | NVIDIA RTX 5090 | 148.5000 | 420 W | 0.353571 |
| 6 | NVIDIA RTX 4090 | 107.0000 | 320 W | 0.334375 |
| 7 | AMD Radeon RX 7900 XT | 66.0000 | 250 W | 0.264000 |
| 8 | AMD Radeon RX 7900 XTX | 74.0000 | 290 W | 0.255172 |
Best GPU for maximum KAWPOW hashrate
The NVIDIA RTX 5090 is the clear leader for raw KAWPOW output. Its hashrate of 148.5000 is higher than every other GPU in the comparison, and its 32 GB of VRAM is also the largest capacity listed.
That performance comes with a 420 W power draw, the highest figure in the group. As a result, the RTX 5090 is most suitable for miners who value maximum hashrate per card and can support its electrical, thermal, and physical requirements. Its hashrate-per-watt figure is 0.353571, placing it fifth in the efficiency ranking rather than first.
Best GPU for power efficiency
The NVIDIA RTX 5070 Ti ranks first for efficiency at 0.424324 hashrate per watt. It combines 78.5000 KAWPOW hashrate with a 185 W power draw, the lowest power figure among the NVIDIA GPUs in this comparison.
Its 16 GB of VRAM is lower than the 24 GB and 32 GB capacities available on some models, but it matches the 16 GB capacity of the RTX 5080, RTX 4080 Super, and RTX 4080. For a rig designed around power efficiency and moderate per-card output, the RTX 5070 Ti is the strongest data-based choice in this list.
Best balance of hashrate and efficiency
The NVIDIA RTX 5080 offers a strong middle position between raw output and efficiency. It reaches 96.0000 KAWPOW hashrate at 240 W and records an efficiency value of 0.400000, ranking second overall.
This makes it more productive per card than the RTX 5070 Ti, although the RTX 5070 Ti uses less power and ranks higher by efficiency. The RTX 5080 has 16 GB of VRAM, so buyers should weigh its higher hashrate against the 5070 Ti’s lower power draw.
How the RTX 4080 models compare
The RTX 4080 Super and RTX 4080 are close in this dataset. The RTX 4080 Super delivers 74.0000 hashrate at 205 W, while the RTX 4080 reaches 71.0000 at 200 W.
The RTX 4080 Super has the better efficiency value at 0.360976, compared with 0.355000 for the RTX 4080. Both GPUs have 16 GB of VRAM, but the Super model provides the higher KAWPOW hashrate and the higher calculated hashrate per watt.
AMD Radeon options for KAWPOW
The AMD Radeon RX 7900 XTX provides 74.0000 KAWPOW hashrate with 24 GB of VRAM and a 290 W power draw. The RX 7900 XT offers 66.0000 hashrate, 20 GB of VRAM, and a 250 W power draw.
Within this comparison, the RX 7900 XT is more efficient than the RX 7900 XTX, with values of 0.264000 and 0.255172 respectively. However, both AMD models rank below the listed NVIDIA GPUs by hashrate per watt based on the supplied figures. Actual mining results can still vary with software, configuration, cooling, and operating conditions.
What miners should consider before buying
- Electricity cost: Power draw directly affects operating expenses, so the most powerful card is not automatically the most profitable.
- Rig power capacity: A card’s stated power draw should be considered alongside the capacity of the power supply, connectors, and the rest of the system.
- VRAM capacity: The listed GPUs range from 16 GB to 32 GB. More VRAM can provide additional flexibility, although the supplied data does not establish a specific minimum for every KAWPOW setup.
- Cooling and airflow: Sustained mining places continuous demand on a GPU. Adequate airflow and temperature monitoring are important for stable operation.
- Market conditions: Coin price, network difficulty, pool fees, hardware pricing, and electricity rates can change profitability. These figures compare hardware performance and are not a guarantee of financial returns.
Conclusion
The NVIDIA RTX 5090 is the best choice in this comparison for maximum KAWPOW hashrate, reaching 148.5000 with 32 GB of VRAM. The NVIDIA RTX 5070 Ti is the efficiency leader at 0.424324 hashrate per watt, while the RTX 5080 offers the second-best efficiency and a higher 96.0000 hashrate.
For a lower-power build, the RTX 5070 Ti is the standout option based on the supplied data. For maximum output per card, the RTX 5090 leads clearly, but its 420 W power draw must be planned for carefully. Miners should evaluate these specifications together with their electricity rate, hardware cost, cooling setup, and current network conditions before making a purchase decision.
