Since I can't mine Ethereum anymore, what is the best and most profitable proof-of-work coin to mine with my GPUs?

Since the Ethereum Merge ended the era of easy, highly profitable GPU mining, the landscape has changed dramatically . GPU mining is no longer a guaranteed passive income printer for the average home setup; instead, profitability bounces dynamically depending heavily on your local electricity cost (ideally under$0.1 0 per kWh) and the specific coin of the week.

Because profitability shifts constantly with market prices and network difficulty, there is no single permanent "best" coin. However, the top Proof-of-Work (PoW) coins that remain the go-to staples for GPU miners include:

• Ravencoin (RVN) : Uses the ASIC-resistant KAWPOW algorithm, making it deeply committed to the GPU community. It has active development and fair distribution, though it tends to run hotter and draw more power than Ethereum ever did.
• Ethereum Classic (ETC) : The original un-merged chain of Ethereum. While it is GPU-mineable, be aware that a vast amount of heavy hash power moves to and from ETC depending on market conditions, and heavy ASIC adoption on the network can squeeze out smaller single-GPU hobbyists.
• Ergo (ERG) : Highly favored for being strictly ASIC-resistant and optimized for GPU architectures. It features efficient memory-hard mining properties, though its fiat profitability relies heavily on broader market rallies.
• Flux (FLUX) : Tied to a decentralized computational cloud infrastructure. Mining Flux often feels more integrated into a decentralized ecosystem (running nodes alongside mining), which appeals to hobbyists looking past pure speculative token rewards.

How to Find What is Most Profitable Right Now

Because margins are thin, you should never mine blindly. Always run your exact card models and local power rates through real-time calculation tools before pointing your rigs anywhere:

• Check live, shifting rankings on WhatToMine to calculate your exact hardware versus power consumption.
• Track network distribution and emerging pools on Mining Pool Stats.

To give you the most accurate target, tell me:

• What exact GPU model(s) are you running?
• What is your local electricity cost (per kWh)?

I can help you figure out if you'll actually turn a profit or if it's better to hold off.

Yes—but the answer in 2026 is very dependent on your exact GPUs and electricity rate. There isn't a single PoW coin that is always most profitable.

As of August 27, 2026, current GPU profitability data points to a few interesting options:

• Ravencoin (RVN / KawPow) — currently one of the stronger actual GPU-mineable choices. Minerstat currently shows an RTX 4090 earning about $4.06/day gross and $3.27/day after its assumed electricity cost on KawPow.
• Conflux (CFX / Octopus) — also competitive on some NVIDIA GPUs; the RTX 5090, for example, is currently showing around $2.34/day net in Minerstat's data.
• Kaspa (KAS / kHeavyHash) — technically GPU-mineable, but ASIC competition makes it much less attractive to GPU miners than it once was.
• Ergo (ERG / Autolykos) — GPU-friendly and efficient, but current revenue is relatively weak. A current RTX 5090 estimate I found shows it losing money at the assumed electricity rate.
• Ethereum Classic (ETC) — still PoW and GPU-mineable, but currently not particularly profitable. For an RTX 4090, one current calculator estimates substantially negative profit at its assumed power rate.
• EthereumPoW (ETHW) — still mineable, but again, current GPU economics aren't particularly compelling.

My pick

If your goal is maximum immediate GPU mining profit, I'd start with Ravencoin/KawPow, then compare it against Conflux for your particular cards.

But there's an important catch: electricity price completely changes the ranking. Mining profitability is fundamentally hash revenue minus power cost, and even relatively modest electricity prices can turn a coin from profitable to a loss.

If you tell me:

1. GPU model(s) — e.g. 4× RTX 3080, 2× 4090, 6× RX 6800 XT
2. Your electricity rate — e.g. $0.10/kWh
3. Whether you're willing to mine one coin and hold it or want maximum daily USD profit

…I can compare RVN, CFX, KAS, ERG, ETC, ETHW, and the other serious GPU PoW candidates and give you the estimated $/day, power consumption, monthly profit, and best coin for your exact rig.

If you mean maximum current profit from existing GPUs, there is no single permanent winner—the best coin changes with difficulty, price, and your electricity rate. After Ethereum moved to proof-of-stake, GPU miners moved to smaller PoW networks, and profitability is much more volatile.

For most GPU rigs today, the shortlist looks like this:

EarnifyHub CoinCalculators### My practical recommendation by situation

• You have cheap electricity (< ~$0.08/kWh):

• Try Kaspa first.

• Consider Alephium if you care more about efficiency and holding a smaller-cap coin.

• You pay average residential rates (~$0.12–$0.18/kWh):

• Check profitability daily before committing.

• Mining may be marginal; switching algorithms frequently matters more than loyalty to one coin.

• You have older ETH-era GPUs (RX 580/5700 XT, GTX 10/20 series, RTX 20/30 series):

• ERG and RVN may still make sense depending on VRAM and power efficiency.

• Newer efficient cards generally do better on Kaspa/ALPH.

• You are buying GPUs specifically to mine:

• I would be cautious. The Ethereum-era economics are gone; hardware ROI is much harder unless you have unusually cheap power or another use for the GPUs.

If you tell me:

1. GPU model(s) (e.g., 6× RTX 3080, RX 6800 XT, 4090, etc.)
2. electricity cost ($/kWh)
3. whether you sell mined coins immediately or hold

…I can rank the coins specifically for your rig.

Since the "Merge" shifted Ethereum to proof-of-stake, traditional GPU mining has transformed from a passive income machine into a razor-thin margin hobby or speculative endeavor . Daily profitability heavily depends on your local cost of electricity, but several proof-of-work coins remain the go-to options for GPU miners.

The top GPU-mineable coins to watch and evaluate on profitability trackers like WhatToMine include:

• Ravencoin (RVN): Utilizes the K A W P O W cap K cap A cap W cap P cap O cap W𝐾𝐴𝑊𝑃𝑂𝑊 algorithm, which is heavily optimized to resist ASIC takeover and remain friendly to consumer GPUs. It has an active community and fair distribution, though profitability fluctuates tightly with market price and power draw.
• Ethereum Classic (ETC): The original chain that retained proof-of-work after Ethereum migrated. It’s one of the higher-hashrate options supported by legacy DAG sizes, making it a default landing spot for heavy GPU arrays, though returns are tightly contested.
• Flux (FLUX): Tied closely to a decentralized computational and cloud infrastructure network. Mining Flux goes a bit beyond raw token generation, supporting a decentralized node ecosystem, which appeals to utility-minded miners.
• Ergo (ERG): Uses the A u t o l y k o s cap A u t o l y k o s𝐴𝑢𝑡𝑜𝑙𝑦𝑘𝑜𝑠 algorithm, designed to be resistant to ASICs and friendly to GPUs with efficient memory-tuning profiles.

A Quick Reality Check on Profitability

• The Math: For most standard household electricity rates (e.g., above$0.1 0–$0.1 2 per kWh kWh k W h ), traditional GPU mining yields pennies a day or operates at a net loss once power bills are paid.
• The Pivot to AI/Cloud: Many former GPU miners have redirected their hardware away from traditional coin mining and toward decentralized AI cloud computing networks (such as RunPod ), where renting out high-end GPUs (like RTX 4090s or 5090s) for machine learning workloads can generate significantly higher daily returns than proof-of-work mining.

If you want to narrow this down, tell me:

• What specific GPU models do you have?
• What is your local electricity cost (per kWh kWh k W h)?

I can help you check whether it makes sense to mine or look at alternative uses for your hardware.

Since the Ethereum Merge, there is no single dominant "gold standard" coin for GPUs . Instead, GPU mining has fragmented into a shifting landscape of ASIC-resistant altcoins and newer algorithmic projects.

The most prominent and frequently profitable coins to mine with GPUs depend heavily on your specific card's VRAM and your local electricity costs. Top contenders include:

• Ethereum Classic (ETC) : Utilizes the Etchash algorithm. It remains the most stable, liquid, and historically familiar post-merge fallback for mid-to-high-range GPUs with adequate VRAM.
• Ravencoin (RVN) : Uses the aggressively ASIC-resistant KawPoW algorithm. It features a heavy power draw, meaning it only pencils out if your electricity rates are low, but it appeals heavily to decentralization-focused hobbyists.
• Ergo (ERG) : Powered by the Autolykos v2 algorithm. It is memory-intensive and performs exceptionally well on graphics cards with strong memory bandwidth.
• Flux (FLUX) : Relies on ZelHash and rewards memory bandwidth, typically requiring GPUs with 8 G B or more of VRAM.
• Emerging/Niche Algorithmic Coins : Newer network shifts and projects (such as micro-cap or specialized computational/AI-adjacent PoW tokens like Pearl) occasionally spike in short-term profitability for high-end CUDA cards (like RTX 4090 or RTX 5080 series), though they carry much higher volatility and liquidity risks. (Note: While Kaspa (KAS) was historically a top GPU pick, it has largely transitioned into ASIC-dominated territory).

Maximizing Your Margins

Because block rewards are tightly contested and margins are thin, success comes down to basic math: R e v e n u e−P o w e r C o s t=P r o f i t.

1. Check Real-Time Data : Plug your exact hardware specs and local power rate ($/k W h ) into profitability aggregators like WhatToMine or Mining Pool Stats before pointing your rig at a specific coin.
2. Tune Your Hardware : Never run stock settings. Undervolting and optimizing your core/memory clocks can slash your power consumption by 2 0% to 3 0% with minimal loss to your hashrate, which is often the difference between losing money and making a small profit.

If you tell me which specific GPU models you have and what you pay for electricity per kWh , I can help you calculate your expected daily return or see if it's worth turning the rigs on.

Yes — but in 2026 the answer is very different from the Ethereum era.

My pick: Ergo (ERG) for GPU mining

If you're specifically looking for a GPU-friendly PoW coin, I'd currently rank the options roughly:

The important caveat is electricity cost. Current profitability data show that GPU mining margins are extremely thin. For example, current Ravencoin calculations show an RTX 4090 generating about $1.06/day of revenue but roughly $0.79/day in electricity under the calculator's assumptions—only ~$0.27/day net.

Kaspa is a particularly important trap: it frequently appears at the top of "most profitable PoW" lists, but I would not buy GPUs specifically to mine KAS. Its kHeavyHash mining ecosystem is heavily ASIC-oriented now.

For GPU miners, Ergo/Autolykos is much more interesting. Current mining comparisons continue to identify Autolykos and kHeavyHash as the leading GPU algorithms, while calculators such as WhatToMine specifically track current GPU profitability across these coins.

But I can give you a much better answer for your GPUs

Tell me:

• GPU model(s) — e.g. 6× RTX 3080, 4× 4090, RX 6800 XT, etc.
• Electricity rate — $/kWh from your bill
• Number of each GPU
• Whether you care about maximum immediate profit or accumulating a coin you think will appreciate

Then I can calculate ERG vs RVN vs ETC vs FLUX vs other GPU-mineable coins, including electricity, and tell you exactly which one I'd mine with your particular rig.

Yes—but “most profitable” depends heavily on your exact GPUs and electricity rate. As of August 15, 2026, GPU mining is a much thinner-margin business than it was during the Ethereum era.

My current shortlist

The big caveat is Kaspa. Older mining guides still put KAS near the top, but Kaspa's network is now dominated by specialized ASICs; the Kaspa project itself notes that GPU/CPU mining has become extremely unprofitable.

For actual GPUs, Ergo is the coin I'd investigate first. Current mining data still lists Autolykos/Ergo among the principal GPU algorithms, while ETC, RVN, Flux, etc. trail it depending on hardware and electricity.

However, there's an important wrinkle: the absolute highest-paying algorithm on today's profitability calculators isn't necessarily the best coin to mine. WhatToMine's current GPU ranking, for example, is showing some obscure coins such as Pearl and Evrmore at the top for particular GPUs rather than the traditional ERG/RVN/ETC choices. whattomine.com Those numbers can change dramatically with difficulty, coin price, and exchange liquidity.

The electricity question is critical

At roughly $0.10/kWh, some GPUs can still eke out a positive margin on certain algorithms. At $0.15–$0.20/kWh, many GPUs are effectively mining at a loss. Current community reports are similarly pessimistic about RVN at ordinary residential electricity rates.

So I wouldn't recommend buying additional GPUs specifically for mining right now. If you already own the GPUs, however, there can be a case for mining when electricity is cheap and/or you value accumulating a particular coin.

If you tell me:

• GPU model(s) — e.g. 6× RTX 3070, 2× 4090, RX 6800 XT, etc.
• electricity cost per kWh
• whether you're willing to auto-switch coins for maximum BTC/USD revenue
• approximately how many GPUs you have

…I can compare ERG vs RVN vs ETC vs FLUX vs the smaller currently profitable coins, calculate estimated $/day, electricity cost, net profit, and break-even electricity price for your actual rig, and tell you what I'd mine today. urlWhatToMine GPU profitability calculatorturn0news1

Since the Ethereum merge shifted the network to Proof-of-Stake, the landscape for consumer GPU mining has changed drastically . While you can no longer pull high yields easily, several prominent proof-of-work altcoins remain viable and are frequently rotated as the top options for graphics cards.

Profitability fluctuates daily based on network difficulty, coin pricing, and your local electricity costs. The leading contenders for GPU mining include:

• Ethereum Classic (ETC) : Utilizing the Etchash algorithm, ETC is the most direct and stable survivor of the post-merge era. It features good exchange liquidity and reliable tooling, making it a comfortable baseline for mid-to-high-end AMD and NVIDIA cards with adequate VRAM.
• Ravencoin (RVN) : Operating on the aggressively ASIC-resistant KawPow algorithm, RVN favors a decentralized ethos. It draws significantly more power and runs hot, but it remains a go-to target when coin prices spike.
• Ergo (ERG) : Powered by the memory-intensive Autolykos v2 algorithm, Ergo is designed to be ASIC-resistant and performs well on cards with strong memory bandwidth.
• Flux (FLUX) : Utilizing ZelHash (Equihash variant), Flux ties into a decentralized cloud computing network. It rewards memory-heavy configurations and requires at least 8 G B VRAM cards.
• Note on Kaspa (KAS) : While historically a massive favorite for GPU miners, the network has largely transitioned into heavy ASIC dominance (kHeavyHash ), making standard consumer GPUs much less competitive there.

Realities of Profitability

GPU mining margins are razor-thin. Unless your electricity cost is exceptionally low (ideally under$0.0 8 to$0.1 0 per kWh kWh k W h ), standard home mining often yields marginal profits or a net loss once power bills are paid.

Before firing up a miner, always plug your specific hardware and local power rates into a real-time profitability aggregator like WhatToMine.

If you share your exact GPU model(s) and your local electricity rate (per kWh) , I can help you check whether mining will net a profit or if you'd be better off looking at alternative uses for your hardware (like renting out compute for AI tasks).

If you already own the GPUs, the answer in August 2026 is: there isn't a universally profitable GPU PoW coin anymore. Electricity cost and your exact GPU matter enormously.

Based on current mining data, I'd rank the practical choices roughly like this:

The important part is that "highest revenue" isn't necessarily "most profitable." For example, current Hashrate.no figures show an RX 580 producing roughly $0.10/day of RVN revenue but losing about $0.23/day at its assumed power cost. www.hashrate.no An AMD VII similarly shows RVN around $0.22/day revenue and about -$0.15/day after electricity at $0.10/kWh.

What I'd actually do

If you have modern NVIDIA cards: I'd start by comparing Ergo, Ravencoin, Flux and whatever currently leads on a profitability calculator, rather than committing to one coin indefinitely.

If you have AMD cards: Ergo becomes particularly interesting. Current benchmarks show, for example, an RX 7900 XTX around 193.9 MH/s on Ergo, while KawPow/RVN is much more power-hungry.

Don't buy GPUs specifically for mining right now. Community reports from 2026 are similarly warning that at ordinary electricity prices, GPU mining often isn't profitable unless you already own the hardware and/or have very cheap electricity.

And I would not choose Kaspa for GPUs. Kaspa has become heavily ASIC-oriented, making GPU mining uncompetitive.

If you give me your hardware, I can make this much more precise

Tell me:

• GPU model(s) and quantity — e.g. 6 × RTX 3070
• your electricity rate — e.g. $0.12/kWh
• whether you care about maximum immediate USD profit or accumulating a coin you think will appreciate

Then I can calculate $/day, electricity/day, net profit/day and monthly profit for the best PoW candidates and tell you exactly which one I'd mine.

Since the Ethereum merge shifted the network to proof-of-stake, single-coin GPU mining has become a dynamic, slim-margin landscape . There is no longer a single "king" coin like ETH that guarantees high profitability for everyone; instead, profitability changes daily based on coin prices, network difficulty, and your local electricity costs.

The top-performing and most viable proof-of-work coins you can mine with GPUs include:

• Kaspa (KAS) : Utilizes the kHeavyHash algorithm. It has been a favorite for efficient NVIDIA cards (like the RTX 40-series) due to its blockDAG architecture allowing ultra-fast block times. Note: ASICs have entered the Kaspa space, but efficient GPUs can still target it depending on difficulty spikes.
• Ethereum Classic (ETC) : Uses the Etchash algorithm. It remains the most straightforward, stable, and widely listed post-merge alternative for traditional GPU miners, working well on mid-to-high-end AMD and NVIDIA cards with adequate VRAM.
• Ravencoin (RVN) : Powered by the KawPoW algorithm. Ravencoin is strictly ASIC-resistant, meaning your GPUs don't have to compete with massive industrial ASIC warehouses. It does feature a notably higher power draw, so efficient cooling and undervolting are critical.
• Flux (FLUX) : Uses ZelHash and heavily rewards memory bandwidth. It ties into a decentralized cloud computing network, giving it a utility-driven ecosystem beyond just speculative trading.
• Ergo (ERG) : Relies on the ASIC-resistant Autolykos v2 algorithm. It is memory-intensive and scales nicely with high-bandwidth graphics cards.

Determining What is Best for You

Because profitability fluctuates rapidly, you should never rely on static lists.

1. Check real-time profitability calculators like WhatToMine or Mining Pool Stats to input your exact GPU models and current local power rates.
2. Always undervolt your GPUs to slash power consumption by 2 0% to 3 0% with minimal loss in hashrate—this is often the difference between mining at a profit or a loss.

If you tell me your exact GPU models (e.g., RTX 3070, RX 6700 XT) and your local electricity cost per kWh , I can help you check if mining is profitable or if an alternative like renting out your GPUs for AI workloads makes more financial sense right now.
