Best GPUs for Mining FISHHASH in 2026: Hashrate and Power Efficiency Compared
FISHHASH mining performance depends on more than raw hashrate. A fast GPU can produce excellent results, but its electricity use, VRAM capacity, purchase cost, cooling requirements and operating environment also affect whether it is practical for a mining rig.
This comparison uses Minector’s internal GPU data for FISHHASH. It covers eight graphics cards from NVIDIA and AMD, comparing their recorded hashrate, power draw and VRAM. An additional ranking orders the GPUs by hashrate per watt, which is a useful starting point for miners focused on energy efficiency.
FISHHASH GPU comparison
The NVIDIA RTX 5090 records the highest FISHHASH hashrate in this group at 165.5000, while the NVIDIA RTX 4090 reaches 120.0000. The newer RTX 5080 and RTX 5070 Ti also perform strongly, with hashrates of 107.0000 and 87.5000 respectively.
Power draw varies considerably between the models. The RTX 5090 uses 420 W, whereas the RTX 5070 Ti draws 185 W. This difference makes efficiency an important consideration, particularly in locations with high electricity prices or limited electrical capacity.

FISHHASH efficiency ranking

Hashrate per watt is calculated by dividing the listed FISHHASH hashrate by the listed power draw. The result indicates how much hashrate a GPU provides for each watt of stated power consumption. It does not represent complete mining-farm efficiency because the calculation excludes the power used by the motherboard, processor, memory, storage, fans and other components.
| Rank | GPU | FISHHASH hashrate | Power draw | Hashrate per watt |
|---|---|---|---|---|
| 1 | NVIDIA RTX 5070 Ti | 87.5000 | 185 W | 0.4730 |
| 2 | NVIDIA RTX 5080 | 107.0000 | 240 W | 0.4458 |
| 3 | NVIDIA RTX 4080 Super | 82.0000 | 205 W | 0.4000 |
| 4 | NVIDIA RTX 4080 | 79.0000 | 200 W | 0.3950 |
| 5 | NVIDIA RTX 5090 | 165.5000 | 420 W | 0.3940 |
| 6 | NVIDIA RTX 4090 | 120.0000 | 320 W | 0.3750 |
| 7 | AMD Radeon RX 7900 XTX | 77.0000 | 290 W | 0.2655 |
| 8 | NVIDIA RTX 3090 Ti | 72.5000 | 340 W | 0.2132 |
Which GPU delivers the highest FISHHASH hashrate?
The NVIDIA RTX 5090 is the clear hashrate leader in the supplied data. Its 165.5000 FISHHASH hashrate is higher than the RTX 4090’s 120.0000 and the RTX 5080’s 107.0000. Its 32 GB of VRAM is also the largest capacity in this comparison.
However, the RTX 5090 also has the highest listed power draw at 420 W. It is therefore best suited to miners who prioritize maximum performance per card and can support the electrical, thermal and physical requirements of a high-power GPU.
Which GPU is the most power efficient?
The NVIDIA RTX 5070 Ti ranks first by hashrate per watt, producing 0.4730 under this comparison. Its 87.5000 hashrate is lower than the performance of the RTX 5090, RTX 4090 and RTX 5080, but its 185 W power draw gives it the strongest efficiency result among the listed GPUs.
The RTX 5080 follows with 0.4458 hashrate per watt. The RTX 4080 Super and RTX 4080 also remain close, at 0.4000 and 0.3950 respectively. These results make the four GPUs attractive options for miners evaluating energy use rather than choosing solely by peak hashrate.
VRAM and rig planning

VRAM is another important specification when selecting a mining GPU. The RTX 5090 provides 32 GB, while the RTX 4090, Radeon RX 7900 XTX and RTX 3090 Ti each provide 24 GB. The RTX 5080, RTX 5070 Ti, RTX 4080 Super and RTX 4080 each have 16 GB.
The available data does not state a specific FISHHASH VRAM requirement, so VRAM capacity should not be treated as a direct profitability measure. Instead, miners should confirm current software requirements and allow for operating-system and mining-application overhead before building a long-term rig.
Practical considerations before buying
A GPU’s hashrate-per-watt result is a useful comparison metric, but it is not a complete profitability calculation. Electricity price, FISHHASH coin price, pool fee, uptime, cooling costs, hardware price and network conditions can all change the final outcome. General profitability figures should therefore be checked with current local inputs rather than inferred from hashrate alone.
Cooling is especially important for higher-power models. The RTX 5090 at 420 W, RTX 3090 Ti at 340 W and RTX 4090 at 320 W may require stronger airflow and more careful thermal management than the lower-power RTX 5070 Ti at 185 W or RTX 4080 at 200 W.
Miners should also verify the power supply, connector compatibility, case clearance and rack spacing before purchasing. Running several GPUs together can create substantial heat and total electrical demand, even when each card appears manageable on its own.
Conclusion
The NVIDIA RTX 5090 is the best choice in this data set for maximum FISHHASH hashrate, reaching 165.5000 with 32 GB of VRAM. The NVIDIA RTX 5070 Ti is the efficiency leader at 0.4730 hashrate per watt, making it the strongest option for miners who place energy consumption at the center of their hardware decision.
The RTX 5080 offers a balance of high hashrate and strong efficiency, while the RTX 4080 Super and RTX 4080 provide competitive power characteristics with 16 GB of VRAM. The AMD Radeon RX 7900 XTX and RTX 3090 Ti deliver lower efficiency in this comparison, although their larger 24 GB VRAM capacities may still interest miners with specific hardware requirements.
These figures are general technical information, not financial, legal or tax advice. A final purchase decision should account for current electricity rates, hardware pricing, pool conditions and other operating costs.
