Best GPUs for Mining ETHASH in 2026: Hashrate and Power Efficiency Compared

Best GPUs for Mining ETHASH in 2026: Hashrate and Power Efficiency Compared

GPU mining performance depends on more than raw hashrate. A card that produces a high ETHASH hashrate may also consume substantially more electricity, while a slightly slower model can deliver better efficiency and lower operating costs. This comparison evaluates eight NVIDIA GPUs using their ETHASH hashrate, power draw, video memory and release year.

The figures are based on Minector’s internal data. Hashrate is shown in MH/s, power draw in watts, and efficiency is calculated as hashrate divided by power draw. The results are useful for comparing hardware characteristics, but profitability also depends on electricity prices, coin prices, pool fees, uptime, cooling and network conditions.

ETHASH GPU comparison

The NVIDIA RTX 5090 delivers the highest hashrate in this group at 190.0000 MH/s, but it also has the highest power draw at 420 W. By contrast, the RTX 5070 Ti produces 108.0000 MH/s at 185 W, making it the most efficient GPU in the comparison.

ETHASH efficiency ranking

Hashrate-per-watt is a practical way to compare energy efficiency. The calculation does not account for purchase price, resale value or electricity cost, but it shows how much ETHASH performance each GPU produces for every watt of listed power draw.

GPU-by-GPU analysis

NVIDIA RTX 5090

The RTX 5090 is the hashrate leader, reaching 190.0000 MH/s on ETHASH. Its 32 GB of VRAM is also the largest capacity in this comparison, providing considerable memory headroom for algorithms and workloads with increasing memory requirements.

Its 420 W power draw places it fourth in the efficiency ranking at 0.4524 MH/s per W. This makes the RTX 5090 attractive when maximum performance per GPU is more important than minimizing power consumption, but the higher draw requires appropriate power delivery, airflow and thermal planning.

NVIDIA RTX 4090 and RTX 3090 Ti

The RTX 4090 produces 130.0000 MH/s using 320 W and includes 24 GB of VRAM. Its efficiency is 0.4063 MH/s per W, which is below the RTX 3090 despite the RTX 4090’s higher hashrate.

The RTX 3090 Ti reaches 127.0000 MH/s at 340 W, with the same 24 GB VRAM capacity. Its 0.3735 MH/s per W result is the lowest among the eight GPUs, so its higher power draw does not translate into a leading efficiency position.

NVIDIA RTX 3090

The RTX 3090 delivers 122.0000 MH/s at 290 W and offers 24 GB of VRAM. Its efficiency is 0.4207 MH/s per W, placing it ahead of both the RTX 4090 and RTX 3090 Ti in the hashrate-per-watt ranking.

For miners evaluating older hardware, the RTX 3090 demonstrates why efficiency should be considered separately from raw hashrate. Its result is not the fastest in the group, but its power-to-performance balance is stronger than the two other 24 GB cards listed here.

NVIDIA RTX 5080 and RTX 5070 Ti

The RTX 5080 offers 120.0000 MH/s at 240 W and includes 16 GB of VRAM. Its efficiency of 0.5000 MH/s per W is second overall, giving it a strong balance between performance and energy use.

The RTX 5070 Ti is the efficiency leader, producing 108.0000 MH/s at 185 W. With 16 GB of VRAM and an efficiency result of 0.5838 MH/s per W, it is the clearest choice in this data set for a power-conscious ETHASH build.

NVIDIA RTX 3080 Ti and RTX 4080 Super

The RTX 3080 Ti reaches 112.0000 MH/s at 250 W and has 12 GB of VRAM. Its 0.4480 MH/s per W efficiency places it fifth, below the newer RTX 5090 but above the RTX 3090, RTX 4090 and RTX 3090 Ti.

The RTX 4080 Super produces 100.0000 MH/s using 205 W and includes 16 GB of VRAM. Its 0.4878 MH/s per W efficiency ranks third, making it a balanced option when moderate hashrate and lower power draw are both important.

How to choose an ETHASH GPU in 2026

Start by deciding whether your priority is maximum hashrate, energy efficiency or VRAM capacity. The RTX 5090 leads on hashrate and VRAM, while the RTX 5070 Ti leads on hashrate-per-watt. The RTX 5080 and RTX 4080 Super occupy the middle ground, combining respectable hashrate with comparatively efficient power use.

Power draw should be evaluated at the rig level, not only per GPU. Multiple cards increase the requirements for the power supply, wiring, ventilation and room cooling. A lower-wattage card can also simplify deployment where electrical capacity or heat removal is limited.

VRAM is another important consideration. The listed GPUs range from 12 GB to 32 GB, but the data provided here does not specify the memory requirement of any particular ETHASH-compatible coin or future network. Before purchasing hardware, verify the memory requirements and mining software support for the exact workload you plan to run.

Ethereum itself no longer uses proof-of-work mining, so an ETHASH comparison should be understood as a hardware-performance reference for ETHASH-compatible networks, testing and related workloads. Actual returns are not determined by hashrate alone and can change with market and network conditions.

Conclusion

The NVIDIA RTX 5090 is the strongest option for maximum ETHASH hashrate, reaching 190.0000 MH/s, and it also provides 32 GB of VRAM. However, its 420 W power draw means that it is not the most efficient choice.

For energy efficiency, the NVIDIA RTX 5070 Ti ranks first at 0.5838 MH/s per W, followed by the RTX 5080 at 0.5000 MH/s per W and the RTX 4080 Super at 0.4878 MH/s per W. The best GPU for a particular mining setup depends on electricity costs, hardware pricing, available power and the memory requirements of the selected ETHASH-compatible workload.

Frequently Asked Questions

Which GPU has the highest ETHASH hashrate?

The NVIDIA RTX 5090 has the highest listed ETHASH hashrate at 190.0000 MH/s. It also has 32 GB of VRAM and a listed power draw of 420 W.

Which GPU is most efficient for ETHASH?

The NVIDIA RTX 5070 Ti is the most efficient GPU in this comparison, with 108.0000 MH/s at 185 W. Its calculated efficiency is 0.5838 MH/s per W.

Does more VRAM always mean better mining performance?

No. VRAM capacity can affect whether a GPU can run a particular workload, but it does not automatically determine hashrate-per-watt. In this comparison, GPUs with different VRAM capacities occupy different positions for both hashrate and efficiency.

Is ETHASH mining still the same as mining Ethereum?

No. Ethereum no longer uses proof-of-work mining. ETHASH performance remains relevant for compatible proof-of-work networks and testing, but miners should confirm the algorithm and memory requirements of the specific network they intend to use.
