Best GPUs for Mining NEXAPOW in 2026: Hashrate and Power Efficiency Compared
NEXAPOW mining performance depends on more than peak hashrate. Electricity consumption, graphics memory, hardware generation, and the way a GPU fits into a mining rig all affect the practical value of a card. This comparison evaluates eight GPUs using the supplied NEXAPOW hashrate, power draw, and VRAM data.
The comparison focuses on hashrate and power efficiency rather than profitability. A profitability estimate would also require an electricity rate, NEXAPOW coin price, pool fee, uptime, and other operating costs. According to Minector’s internal data, the NVIDIA RTX 5070 Ti delivers the highest efficiency among the tested GPUs, while the NVIDIA RTX 5090 provides the highest absolute hashrate.

Efficiency Ranking: Hashrate per Watt
Efficiency is especially important when electricity represents a large share of mining expenses. The following ranking orders the GPUs by reported NEXAPOW hashrate divided by power draw, with the highest result first.
| Rank | GPU | NEXAPOW hashrate | Power draw | Hashrate per watt |
|---|---|---|---|---|
| 1 | NVIDIA RTX 5070 Ti | 9.9000 | 185 W | 0.0535 |
| 2 | NVIDIA RTX 5080 | 12.1000 | 240 W | 0.0504 |
| 3 | NVIDIA RTX 4080 Super | 9.3000 | 205 W | 0.0454 |
| 4 | NVIDIA RTX 4080 | 9.0000 | 200 W | 0.0450 |
| 5 | NVIDIA RTX 5090 | 18.8000 | 420 W | 0.0448 |
| 6 | NVIDIA RTX 4090 | 13.5000 | 320 W | 0.0422 |
| 7 | AMD Radeon RX 7900 XTX | 8.7000 | 290 W | 0.0300 |
| 8 | NVIDIA RTX 3090 Ti | 8.2000 | 340 W | 0.0241 |
1. NVIDIA RTX 5070 Ti
The RTX 5070 Ti ranks first for efficiency, producing a reported NEXAPOW hashrate of 9.9000 at 185 W. Its result of 0.0535 hashrate per watt makes it the strongest option in this list for miners prioritizing power efficiency.
It includes 16 GB of VRAM and was released in 2025. Its lower power draw may also simplify thermal management compared with higher-consumption cards, although the complete rig still needs suitable airflow and power delivery.
2. NVIDIA RTX 5080
The RTX 5080 takes second place with 0.0504 hashrate per watt. Its 12.1000 NEXAPOW hashrate at 240 W gives it a useful balance between output and energy consumption.
With 16 GB of VRAM and a 2025 release year, it may appeal to miners who want more hashrate than the RTX 5070 Ti without moving to the 420 W power draw of the RTX 5090.
3. NVIDIA RTX 4080 Super and RTX 4080
The RTX 4080 Super delivers 9.3000 at 205 W, resulting in an efficiency score of 0.0454. The RTX 4080 produces 9.0000 at 200 W and reaches 0.0450 hashrate per watt. Their efficiency is closely matched, with the Super model offering the higher reported hashrate.
Both GPUs have 16 GB of VRAM. The RTX 4080 was released in 2022, while the RTX 4080 Super was released in 2024, so buyers should consider acquisition cost, condition, warranty coverage, and availability alongside the performance figures.
4. NVIDIA RTX 5090
The RTX 5090 has the highest absolute NEXAPOW hashrate in the comparison: 18.8000. However, its 420 W power draw places it fifth in the efficiency ranking, at 0.0448 hashrate per watt.
Its 32 GB of VRAM is the largest capacity in this comparison. The RTX 5090 may therefore suit miners who value maximum output from each GPU or want substantial memory capacity, but its electrical and cooling requirements deserve careful planning.
5. NVIDIA RTX 4090
The RTX 4090 reports 13.5000 at 320 W, producing 0.0422 hashrate per watt. This is lower efficiency than the RTX 5090 despite the RTX 4090’s lower absolute power draw, because its reported hashrate is also lower.
Released in 2022, the RTX 4090 has 24 GB of VRAM. It remains a high-output option in the dataset, but its position in a new 2026 mining build will depend heavily on purchase price and the cost of operating a 320 W GPU.
6. AMD Radeon RX 7900 XTX and NVIDIA RTX 3090 Ti
The Radeon RX 7900 XTX delivers 8.7000 at 290 W, for an efficiency result of 0.0300. The RTX 3090 Ti reports 8.2000 at 340 W and ranks last at 0.0241 hashrate per watt.
Both cards offer 24 GB of VRAM and were released in 2022. Their memory capacity remains notable, but the supplied NEXAPOW figures show a clear efficiency gap compared with the newer NVIDIA GPUs in this comparison.
How to Choose a GPU for NEXAPOW Mining
Miners with expensive electricity should generally start by examining hashrate per watt. The RTX 5070 Ti leads this metric, followed by the RTX 5080, making both particularly relevant for efficiency-focused builds. Nevertheless, the best purchase depends on the GPU’s market price, expected uptime, cooling environment, and electricity rate.
Miners who need the highest hashrate from a single card may prefer the RTX 5090, which reaches 18.8000. A multi-GPU rig also requires attention to motherboard spacing, power supply capacity, risers, ventilation, and the heat produced by the entire system rather than by the graphics card alone.
VRAM should be treated as a compatibility and longevity factor rather than a direct measure of NEXAPOW performance. The tested cards range from 16 GB to 32 GB, but the supplied data does not establish a minimum VRAM requirement for NEXAPOW. Always verify current software requirements before purchasing hardware specifically for long-term mining.
Conclusion
The NVIDIA RTX 5070 Ti is the efficiency leader in this comparison, delivering 0.0535 hashrate per watt from 9.9000 at 185 W. The NVIDIA RTX 5080 follows with 0.0504, while the RTX 4080 Super and RTX 4080 provide closely matched efficiency.
The NVIDIA RTX 5090 is the clear hashrate leader at 18.8000, but its 420 W draw makes it a less efficient choice than the RTX 5070 Ti and RTX 5080. The AMD Radeon RX 7900 XTX and NVIDIA RTX 3090 Ti offer substantial VRAM, yet they rank lower by hashrate per watt using the supplied NEXAPOW data.
