How Much Can an Ethereum GPU Mining Rig Earn in a Day?

·

Ethereum mining using GPU rigs has been a popular method for individuals seeking to generate passive income through cryptocurrency. While Ethereum's transition to Proof-of-Stake (The Merge) has rendered traditional mining obsolete for the mainnet, many still explore GPU mining on Ethereum Classic (ETC) and other GPU-mineable blockchains. This article explores how much a typical GPU mining rig can earn in a single day, focusing on real-world performance, cost considerations, and profitability calculations.

Understanding Ethereum GPU Mining Rigs

A GPU mining rig is a specialized computer system built primarily for cryptocurrency mining. The most critical component is the graphics card (GPU), which accounts for approximately 80% of the total hardware cost. Other essential components include the motherboard, power supply unit (PSU), RAM, and storage.

These rigs are designed to maximize computational power for hashing algorithms like Ethash, used by Ethereum and similar networks. High-end GPUs such as the AMD RX 570, NVIDIA RTX 3060, or RX 6700 XT are commonly used due to their efficiency and availability.

Key Factors Affecting Daily Mining Earnings

Several variables influence how much a GPU mining rig earns per day:

For accurate forecasting, it's crucial to use up-to-date data from reliable sources while understanding that results are theoretical and subject to change.

Case Study: An 8-GPU Mining Rig with RX 570 Cards

Let’s analyze a real-world example of a professional-grade GPU mining rig equipped with 8x AMD RX 570 4GB graphics cards. This configuration is widely used due to its balance between cost and performance.

Specifications:

This rig is capable of mining multiple cryptocurrencies, including:

However, for this analysis, we focus on Ethereum Classic, one of the most viable successors to Ethereum’s original Proof-of-Work model.

Calculating Daily Earnings: Step-by-Step Breakdown

To estimate daily profits, we follow this formula:

Daily Net Profit = (Daily Revenue in Fiat) – (Daily Electricity Cost)

Step 1: Estimate Daily Revenue

Using current network data and average block rewards:

Note: These figures are theoretical and based on stable network conditions.

Step 2: Calculate Electricity Expenses

The rig consumes 1200W (1.2 kW). Running 24 hours:

Step 3: Determine Net Profit

⚠️ This reveals a critical insight: under current market conditions, mining ETC with this rig results in a loss, not profit.

Even if we consider higher hashrates or lower electricity rates (e.g., ¥0.3/kWh), profitability remains marginal unless hardware costs are significantly reduced or coin prices rise substantially.

Frequently Asked Questions (FAQ)

Q1: Can I still mine Ethereum with a GPU in 2025?

No. Ethereum completed its transition to Proof-of-Stake in 2022 ("The Merge"). Mining ETH is no longer possible. However, you can mine alternative coins like Ethereum Classic (ETC), Ravencoin (RVN), or Ergo (ERG) using GPU rigs.

Q2: What affects GPU mining profitability the most?

The biggest factors are electricity cost, coin price, and network difficulty. Even high-hashrate rigs become unprofitable if power costs exceed $0.10–$0.12 per kWh without subsidized rates.

Q3: Is building a mining rig worth it today?

For most individuals, building a dedicated mining rig is not financially viable due to high initial costs, declining GPU resale values, and rising energy prices. It may only make sense in regions with extremely cheap electricity (<$0.05/kWh) or for those repurposing existing hardware.

Q4: How long does it take to recover the investment?

With the example rig costing ¥16,500 and generating a theoretical daily profit of just a few yuan (or a loss), payback periods exceed several years, if ever achieved. In many cases, miners never recoup their initial investment.

Q5: Are there better alternatives to home mining?

Yes. Cloud mining services and staking offer lower barriers to entry and reduced operational risks. Alternatively, investing directly in crypto assets may yield better long-term returns than attempting to mine them.

Final Thoughts: Is GPU Mining Still Viable?

While GPU mining once offered attractive returns during Ethereum’s early boom years, the landscape has shifted dramatically. With Ethereum no longer mineable, reduced profitability on alternatives, and rising operational costs, most individual miners now operate at a loss.

Successful mining operations today are typically large-scale farms located in areas with subsidized electricity and optimized cooling systems. For average users, the better strategy lies in purchasing crypto directly or participating in staking programs rather than attempting to mine.

That said, if you already own a powerful GPU setup used for gaming or rendering, running it occasionally on low-difficulty networks might yield minor supplemental income — but don’t expect life-changing profits.
