ETH GPU Hashrate Chart: 2025 Ethereum Mining Performance Rankings

·

With growing interest in blockchain technology and decentralized networks, GPU mining remains a topic of interest for tech enthusiasts and hardware hobbyists. While the Ethereum network has transitioned to proof-of-stake, historical data on GPU performance for ETH mining still holds value for those exploring alternative proof-of-work blockchains or studying mining efficiency trends. This guide presents a refined overview of GPU hashrates and power consumption based on real-world testing from experienced miners, updated for accuracy and relevance in 2025.

The following rankings focus on Ethereum (ETH) and Conflux (CFX)—two cryptocurrencies that historically offered strong returns for GPU miners. Although ETH is no longer mineable via Proof-of-Work, this data remains useful for understanding hardware capabilities in compute-intensive environments.

AMD GPU Ethereum Mining Performance

AMD graphics cards have long been favored in mining rigs due to their memory bandwidth and efficiency under specific workloads. Below is a performance ranking from lower to higher hashrates, focusing exclusively on ETH mining. Note: AMD GPUs are generally not recommended for CFX mining due to lower returns compared to NVIDIA counterparts.

The Radeon VII stands out as AMD’s flagship mining card from its generation, delivering high bandwidth and consistent output. However, its power draw makes it less efficient than some newer alternatives.

NVIDIA GPU Ethereum Mining Performance

NVIDIA GPUs dominate both ETH and CFX mining due to superior driver optimization and memory management. The list below ranks models by increasing hashrate for Ethereum mining.

NVIDIA’s Ampere series (RTX 30-series) offered significant leaps in hashrate efficiency, especially the RTX 3060 Ti and above. Even years later, these cards remain relevant for parallel computing tasks.

NVIDIA GPU Conflux (CFX) Mining Efficiency

Conflux Network, a proof-of-work blockchain with eco-friendly consensus mechanisms, supports GPU mining and favors NVIDIA hardware with at least 8GB VRAM. Notably, second-gen (Turing) cards like the RTX 2xxx series often outperformed later models when mining CFX due to algorithmic optimizations.

💡 Note: CFX profitability depends heavily on market price, network difficulty, and electricity costs. Always calculate net returns before deployment.

Power Consumption & Mining Rig Considerations

Hashrate data reflects single-GPU performance only. A complete mining rig includes additional power draw from:

This brings typical platform power usage to 100–200W per rig, depending on configuration.

To ensure stability:

Use a PSU rated 25–30% higher than your total expected draw. For example, a system drawing ~1,000W should use a 1,250W or higher-quality power supply.

Many consumer-grade PSUs are overrated or lack sustained load capacity. Industrial-grade or server-grade units are recommended for continuous operation.

Frequently Asked Questions

Q: Is Ethereum still mineable with GPUs in 2025?

A: No. Ethereum completed its transition to proof-of-stake in September 2022 ("The Merge"). GPU mining is no longer possible on the mainnet. This data is historical but applicable to similar PoW chains.

Q: Why do some older NVIDIA cards perform better on CFX?

A: The Conflux algorithm favors memory latency and bandwidth characteristics present in Turing architecture (RTX 2xxx). Newer architectures may not scale proportionally due to changes in memory controller design.

Q: How accurate are these hashrate numbers?

A: Data was compiled from real-world tests by experienced miners as of early March 2021. Actual results vary based on BIOS settings, overclocking, ambient temperature, and driver versions.

Q: Can AMD cards be used for CFX mining?

A: Technically yes, but returns are significantly lower than NVIDIA equivalents. Most miners prefer NVIDIA GPUs for CFX due to better software support and efficiency.

Q: What factors affect mining profitability today?

A: Key considerations include:

  • Electricity cost per kWh
  • Hardware depreciation rate
  • Network difficulty and coin price volatility
  • Alternative uses (e.g., staking, DeFi participation)

Q: Are there risks involved in building a mining rig?

A: Yes. Risks include hardware wear, fire hazards from poor wiring, regulatory changes, and financial loss if coin values drop. Always assess local laws and safety standards before setup.

Final Thoughts

While traditional ETH GPU mining is obsolete, the principles of hardware evaluation—hashrate, power efficiency, thermal management—remain vital in blockchain infrastructure. Whether you're repurposing old GPUs or exploring new consensus models, understanding past performance helps inform future decisions.
