In the ever-evolving world of cryptocurrency, GPU mining remains a compelling option for tech-savvy investors and enthusiasts. Among the latest hardware, NVIDIA’s GeForce RTX 4090 stands out as a powerhouse, offering unmatched computational performance and energy efficiency. But just how much can you earn per day mining with a 4090 in 2025? This article dives deep into the real-world profitability of 4090 mining, factoring in power costs, market volatility, and long-term sustainability—giving you a clear, data-driven perspective on whether it’s worth the investment.
Why the RTX 4090 Dominates GPU Mining
The RTX 4090 is built on NVIDIA’s advanced Ada Lovelace architecture, delivering exceptional hash rates across popular mining algorithms. Its 24GB of GDDR6X memory and 16,384 CUDA cores make it ideal for memory-hard algorithms like Ethash (used by Ethereum Classic) and KawPow (used by Ravencoin). In optimal conditions:
- Ethash performance: Up to 120 MH/s
- KawPow performance: Around 60 MH/s
This level of performance significantly outpaces previous-generation cards like the RTX 3080 or even the 3090, making the 4090 one of the most efficient mining GPUs available today.
Breaking Down Daily Mining Revenue
Mining income isn’t just about raw hash rate—it’s a balance of market value, network difficulty, and operational costs.
Ethereum Classic (ETC) Mining Example
While Ethereum (ETH) has transitioned to proof-of-stake, Ethereum Classic continues to support GPU mining. As of early 2025, ETC trades around $35, with a network difficulty that allows a 4090 to mine approximately 0.035 ETC per day at 120 MH/s.
- Daily gross revenue:
0.035 ETC × $35 = **$1.23**
Ravencoin (RVN) Mining Example
Ravencoin remains a favorite among GPU miners due to its ASIC-resistant design. At a hash rate of 60 MH/s on KawPow:
- A 4090 can mine roughly 350 RVN per day
- With RVN priced at $0.025, daily earnings are:
350 × $0.025 = **$8.75**
Although RVN offers higher nominal returns, remember that both network difficulty and coin price fluctuate daily—sometimes dramatically.
Real-World Operating Costs
Profitability hinges on keeping expenses low—especially electricity.
Power Consumption & Electricity Costs
The RTX 4090 consumes about 450 watts under full load. When factoring in motherboard, CPU, and system overhead, total system draw reaches roughly 550W.
Assuming an electricity rate of $0.10 per kWh:
- Hourly cost: 0.55 kW × $0.10 = $0.055
- Daily cost: $0.055 × 24 = **$1.32**
At this rate, mining Ravencoin yields a net loss ($8.75 - $1.32 = $7.43 gross, but after pool fees). However, in regions with cheaper power—such as $0.06/kWh or lower—the equation improves significantly.
Additional Expenses
Don’t overlook:
- Pool fees: Typically 1–2% of earnings
- Hardware depreciation: GPUs degrade over time under constant load
- Cooling and maintenance: Dust buildup and thermal stress reduce efficiency
Frequently Asked Questions (FAQ)
Q: Can the RTX 4090 still mine Ethereum (ETH)?
A: No. Ethereum completed its shift to proof-of-stake in 2022 (The Merge), ending GPU mining for ETH. However, alternatives like Ethereum Classic (ETC) and Ravencoin (RVN) remain viable.
Q: Is mining with a 4090 profitable in 2025?
A: It depends on your electricity cost and chosen cryptocurrency. At $0.10/kWh, profits are slim or negative for most coins. But with access to low-cost power (<$0.07/kWh), mining assets like RVN or ETC can generate modest returns.
Q: How long does a 4090 last when used for mining?
A: Under continuous full-load operation, expect a lifespan of 12–18 months before performance degrades noticeably. Proper cooling and undervolting can extend longevity.
Q: Should I mine or just buy crypto directly?
A: In most cases, buying crypto outright is more cost-effective than mining with consumer hardware. Mining introduces overheads like power, wear-and-tear, and setup complexity that often outweigh rewards unless you have near-free electricity.
Q: What’s the best algorithm for the 4090 in 2025?
A: Currently, KawPow (Ravencoin) and Etchash (Ethereum Classic) offer the best compatibility and returns. Some miners also experiment with Alephium or Nexa, but liquidity and stability favor RVN and ETC.
Q: Does mining damage the GPU?
A: Yes. Continuous high temperatures and power draw accelerate component aging. While modern GPUs are robust, prolonged mining increases failure risk—especially if cooling is inadequate.
Long-Term Outlook: Is GPU Mining Still Viable?
The golden era of easy GPU mining profits has passed. Increased competition, declining coin rewards, rising energy costs, and regulatory scrutiny have made small-scale mining less attractive.
Moreover, many networks are exploring algorithm changes or transitioning away from proof-of-work entirely. This uncertainty means today’s profitable coin could be obsolete tomorrow.
That said, GPU mining still holds niche value:
- For hobbyists learning blockchain technology
- In areas with subsidized or surplus electricity
- As part of diversified crypto investment strategies

Final Verdict: How Much Can You Earn Per Day?
Let’s summarize realistic expectations for a single RTX 4090 miner in 2025:
| Metric | Value |
|---|---|
| Hash Rate (KawPow) | ~60 MH/s |
| Daily RVN Mined | ~350 RVN |
| RVN Price | ~$0.025 |
| Gross Daily Revenue | ~$8.75 |
| Power Cost (550W @ $0.10/kWh) | $1.32 |
| Pool Fees (1%) | ~$0.09 |
| Net Daily Profit | ~$7.34 |
However, at higher electricity rates ($0.15+/kWh), this becomes unprofitable.
For ETC mining:
- Net profit ≈ $1.23 - $1.32 = -$0.09/day (a slight loss)
Conclusion: Mining Is Now a Calculated Risk
The RTX 4090 is undeniably powerful—but raw performance doesn’t guarantee profit. In 2025, GPU mining is no longer a passive income stream for most users. Success requires:
- Access to cheap electricity
- Constant monitoring of market trends
- Willingness to switch coins rapidly
- Acceptance of hardware wear
For the average user, trading or staking through secure platforms often delivers better risk-adjusted returns than home mining.
