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

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

Choosing a GPU for OCTOPUS mining requires more than looking at the highest hashrate. A faster card may also consume substantially more electricity, while a slightly slower model can deliver better hashrate per watt and potentially offer a more practical operating profile.

This comparison uses Minector’s internal data for eight GPUs, including NVIDIA’s RTX 50-series and RTX 40-series cards, AMD’s Radeon RX 7900 XTX, and the older RTX 3090 Ti. The key figures are OCTOPUS hashrate, power draw, VRAM, and calculated hashrate-per-watt efficiency.

OCTOPUS GPU comparison

The table below presents the supplied hardware data without changing the reported hashrate, power, or memory figures. The efficiency column is calculated by dividing OCTOPUS hashrate by power draw in watts and is shown to four decimal places.

Best GPUs ranked by OCTOPUS efficiency

Hashrate-per-watt is useful when electricity is a major part of mining costs. It does not represent profit by itself, because profitability also depends on the electricity rate, OCTOPUS network conditions, coin price, pool fee, uptime, and the purchase price of the hardware.

1. NVIDIA RTX 5070 Ti

The RTX 5070 Ti takes first place for OCTOPUS efficiency in this comparison. Its 130.0000 hashrate at 185 W produces 0.7027 hashrate per watt, the highest result among all eight GPUs.

Its 16 GB of VRAM is lower than the capacity of the RTX 5090, RTX 4090, Radeon RX 7900 XTX, and RTX 3090 Ti. However, the combination of the strongest measured efficiency and moderate power draw makes it particularly interesting for miners focused on electricity consumption and compact system design.

2. NVIDIA RTX 5080

The RTX 5080 records 160.0000 at 240 W, resulting in 0.6667 hashrate per watt. It ranks second for efficiency while delivering the second-highest hashrate in the comparison.

With 16 GB of VRAM, it sits below the larger-memory cards in capacity, but its OCTOPUS performance is stronger than the RTX 5070 Ti. It may suit miners who want a balance between per-card output and energy efficiency.

3. NVIDIA RTX 4080 Super

The RTX 4080 Super produces 122.0000 at 205 W. Its calculated efficiency is 0.5951, placing it narrowly ahead of the RTX 5090 and RTX 4080 on hashrate per watt.

This card does not lead the group in raw hashrate, but its 205 W power draw keeps it competitive in the efficiency ranking. Its 16 GB of VRAM is the same as the RTX 5080 and RTX 5070 Ti.

4. NVIDIA RTX 5090

The RTX 5090 is the clear raw-hashrate leader, reaching 248.0000 on OCTOPUS. It also has the largest VRAM capacity in the comparison at 32 GB.

That output comes with a 420 W power draw, so the card ranks fourth for efficiency at 0.5905 hashrate per watt. It is therefore the strongest choice in this data set for maximum hashrate per GPU, but not the top choice when minimizing power use is the priority.

5. NVIDIA RTX 4080

The RTX 4080 delivers 118.0000 at 200 W and records 0.5900 hashrate per watt. Its efficiency is close to the RTX 4080 Super, although its OCTOPUS hashrate is lower at a slightly smaller power draw.

The card includes 16 GB of VRAM and remains a balanced option within the RTX 40-series data shown here. Actual suitability will depend on acquisition cost, availability, cooling, and local electricity pricing.

6. NVIDIA RTX 4090

The RTX 4090 reaches 178.0000 at 320 W, giving it 0.5563 hashrate per watt. It offers the second-highest raw hashrate in the comparison and 24 GB of VRAM.

Its efficiency is below the RTX 50-series cards listed here and below the RTX 4080 models. Nevertheless, its combination of substantial hashrate and 24 GB memory may remain relevant where used hardware is priced attractively.

7. AMD Radeon RX 7900 XTX

The Radeon RX 7900 XTX records 110.0000 at 290 W, equivalent to 0.3793 hashrate per watt. It has 24 GB of VRAM, giving it more memory than the 16 GB NVIDIA models in this comparison.

However, its measured OCTOPUS efficiency is considerably lower than the NVIDIA GPUs listed above it. Buyers should evaluate its complete system cost and electricity requirements rather than selecting it on VRAM capacity alone.

8. NVIDIA RTX 3090 Ti

The RTX 3090 Ti produces 108.0000 at 340 W and ranks last for efficiency at 0.3176 hashrate per watt. Its 24 GB of VRAM is substantial, but the supplied figures show the lowest OCTOPUS hashrate and the highest power draw relative to its output among the older cards.

It may be considered only when the purchase price is especially favorable or when an existing card can be repurposed. New buyers should pay close attention to the electricity impact of its 340 W draw.

What miners should consider beyond hashrate

Power draw should be treated as an operating specification, not a guaranteed electricity bill. The final cost depends on the miner’s electricity rate, how consistently the GPU runs, cooling requirements, and the rest of the system.

VRAM is another comparison point, although this data set does not establish a specific OCTOPUS memory requirement. More memory can provide additional hardware flexibility, but it does not automatically produce higher hashrate or better efficiency.

Pool fees, network difficulty, OCTOPUS market conditions, and hardware pricing can change over time. For that reason, use the hashrate and efficiency figures as technical reference points and calculate current returns with up-to-date operating assumptions before making a purchase decision.

Conclusion

The NVIDIA RTX 5070 Ti is the efficiency winner for OCTOPUS mining, with 0.7027 hashrate per watt from 130.0000 at 185 W. The RTX 5080 follows with 0.6667, while the RTX 4080 Super, RTX 5090, and RTX 4080 form a closely grouped middle tier.

The NVIDIA RTX 5090 is the best performer for maximum hashrate per card at 248.0000, but its 420 W power draw places it behind the most efficient options. The AMD Radeon RX 7900 XTX and NVIDIA RTX 3090 Ti offer larger VRAM capacities than several newer cards, yet rank lower on the supplied OCTOPUS efficiency figures.

Frequently Asked Questions

Which GPU has the highest OCTOPUS hashrate?

The NVIDIA RTX 5090 has the highest OCTOPUS hashrate in this comparison at 248.0000. It uses 420 W and has 32 GB of VRAM.

Which GPU is most power-efficient for OCTOPUS mining?

The NVIDIA RTX 5070 Ti ranks first at 0.7027 hashrate per watt, based on 130.0000 hashrate and 185 W power draw. This is the highest calculated efficiency among the eight GPUs.

Does more VRAM mean better OCTOPUS mining performance?

Not necessarily. The supplied figures show that VRAM capacity and OCTOPUS hashrate do not increase in a simple one-to-one relationship. VRAM should be considered alongside hashrate, power draw, price, and the intended mining setup.

Is the most efficient GPU automatically the most profitable?

No. Efficiency is an important input, but profitability also depends on electricity cost, coin price, network conditions, pool fees, hardware cost, cooling, and uptime. Treat these figures as general technical information rather than definitive financial advice.
