Ethereum (ETH) mining has long been a compelling avenue for individuals seeking to participate in the cryptocurrency ecosystem through proof-of-work mechanisms. While Ethereum’s transition to proof-of-stake has since rendered traditional GPU mining obsolete, many readers may still be researching historical mining setups, comparing hardware performance, or exploring alternative blockchains that continue to support GPU-based consensus models. This article provides a detailed breakdown of GPU hashrate performance for ETH mining, guidance on selecting suitable graphics cards, and insights into efficiency, cost recovery, and optimal operating conditions—offering valuable context for both retrospective analysis and future decentralized network participation.
Understanding GPU Hashrate in Ethereum Mining
Hashrate is the measure of computational power used to solve cryptographic puzzles and validate transactions on a blockchain. In the context of Ethereum mining, higher GPU hashrates directly translate to increased chances of earning block rewards. Although ETH no longer relies on mining, GPUs that once excelled in this domain remain relevant for other cryptocurrencies like Ravencoin, Ergo, and Beam, which continue to support GPU mining.
The efficiency of a graphics card in mining operations depends on several factors:
- VRAM capacity (minimum 4GB recommended)
- Power consumption
- Thermal performance
- Cost-to-performance ratio
Among the most popular GPUs historically used for Ethereum mining were AMD’s RX series and NVIDIA’s GTX 10-series. However, one key technical requirement emerged during ETH’s proof-of-work era: the DAG file size grew over time, making 2GB VRAM insufficient. As a result, cards like the GTX 1050 with only 2GB of memory became incapable of mining ETH at all.

Top GPUs for Ethereum Mining: Performance Breakdown
Below is a comprehensive overview of the most widely used GPUs during the peak of ETH mining, ranked by effective hashrate and efficiency.
AMD Radeon RX Series – The Mining King
AMD GPUs have traditionally dominated the mining scene due to their superior memory bandwidth and open-source driver support.
RX 580 / RX 570:
- Hashrate: ~28–30 MH/s
- Power Draw: ~120–150W (optimized with undervolting)
- VRAM: 8GB GDDR5
- Notes: These cards offered excellent price-to-performance ratios and were easily modifiable for improved efficiency.
RX 470:
- Hashrate: ~26–29 MH/s
- Power Draw: ~100–120W
- VRAM: 4GB/8GB variants
- Notes: Highly sought after during mining booms due to low power consumption and strong output.
A notable advantage of AMD cards was their ability to be chained together using risers in multi-GPU rigs—some miners deployed 6 to 8 cards per system, achieving over 150 MH/s on a single rig.
NVIDIA GTX 10-Series – Solid but Less Efficient
While NVIDIA cards performed well, they generally lagged behind AMD counterparts in terms of power efficiency and memory optimization.
GTX 1080 Ti:
- Hashrate: ~30–33 MH/s
- Power Draw: ~220–250W
- VRAM: 11GB GDDR5X
- Notes: Powerful but power-hungry; better suited for high-end rigs where performance outweighed energy costs.
GTX 1070 / GTX 1060 (6GB):
- Hashrate: ~20–23 MH/s (1070), ~18–20 MH/s (1060)
- Power Draw: ~120–150W
- VRAM: 6GB/8GB variants
- Notes: Entry-level options for small-scale miners; limited scalability.
⚠️ Critical Note: The GTX 1050 with 2GB VRAM cannot mine Ethereum due to insufficient memory. Even basic DAG file requirements exceeded its capacity, rendering it ineffective. Only GPUs with 4GB or more VRAM should be considered for any serious mining effort.
Building a Profitable Mining Rig: Key Considerations
Creating a functional and profitable mining setup involves more than just selecting powerful GPUs. Several operational factors influence long-term success:
Multi-GPU Configuration
To achieve meaningful returns, single-card setups are rarely viable. A standard professional mining rig typically consists of 6 GPUs, delivering aggregate hashrates of 80 MH/s or higher. For example:
- Six RX 580s @ ~29 MH/s each = ~174 MH/s total
- Estimated build cost: Under $1,000–$1,500 (depending on market conditions)
Such configurations allowed miners to recoup initial investments within 5 to 6 months during favorable market conditions—assuming stable electricity rates and consistent coin prices.
Cooling and Ventilation
Heat management is critical when running multiple GPUs continuously. Overheating reduces performance and shortens hardware lifespan.
Best practices include:
- Spacing cards at least 1–2 slots apart
- Using open-frame cases or custom racks
- Installing additional case fans for airflow
- Operating in well-ventilated, cool environments
Poor thermal design can lead to throttling, reducing actual hashrate by up to 15%.

Frequently Asked Questions (FAQ)
Q: Can I still mine Ethereum with a GPU in 2025?
A: No. Ethereum completed its transition to proof-of-stake with "The Merge" in September 2022. GPU mining is no longer possible on the mainnet. However, some Ethereum forks (like Ethereum Fair) still allow mining.
Q: What is the minimum VRAM needed for ETH mining?
A: At least 4GB of VRAM is required. Cards with less (e.g., GTX 1050 2GB) cannot handle the growing DAG file size and will fail to mine.
Q: Which GPU offered the best return on investment during ETH mining?
A: The AMD RX 580 was widely regarded as the best value due to its balance of hashrate (~30 MH/s), power efficiency, and affordability during mass adoption periods.
Q: How long did it take to recoup mining rig costs?
A: Under optimal conditions—low electricity costs, stable ETH prices—a well-configured 6-GPU rig could break even in approximately 5.5 months.
Q: Are NVIDIA cards worse than AMD for mining?
A: Not inherently worse, but AMD GPUs generally provided better memory bandwidth and lower power draw per MH/s, giving them an edge in large-scale deployments.
Q: Can old mining GPUs be repurposed?
A: Yes. Many former mining GPUs are now used for gaming, video rendering, AI inference tasks, or staking through integrated wallets.
