How we calculate
In FlowHash, NVIDIA RTX cards mine Pearl (PRL) on the pearlhash algorithm. It loads the tensor cores — the matrix-math units that power AI and DLSS. So what matters most for profitability is the number and generation of tensor cores, not the amount of video memory as in the Ethereum days.
For each card we list the hashrate (TH/s), power draw under load, monthly income and profit after electricity at $0.10 per kWh. The hashrate is a FlowHash estimate for the reference version of the card: factory-overclocked versions are slightly faster, laptop versions slower. All figures are at the rate of October 25, 2026 and are recalculated at the current rate when you open the page.
Top 10 GPUs by income
| # | GPU | Hashrate | Power | Income / mo | Profit at $0.10 | Pays off up to, $/kWh |
|---|---|---|---|---|---|---|
| 1 | RTX 5090 | 402 TH/s | 573 W | $339.18 | $297.92 | $0.82 |
| 2 | RTX 4090 | 316 TH/s | 441 W | $266.62 | $234.87 | $0.84 |
| 3 | RTX 5080 | 228 TH/s | 360 W | $192.37 | $166.45 | $0.74 |
| 4 | RTX 4080 | 220 TH/s | 255 W | $185.62 | $167.26 | $1.01 |
| 5 | RTX 4080 SUPER | 206 TH/s | 262 W | $173.81 | $154.94 | $0.92 |
| 6 | RTX 5070 Ti | 178 TH/s | 300 W | $150.18 | $128.58 | $0.70 |
| 7 | RTX 4070 Ti SUPER | 165 TH/s | 235 W | $139.22 | $122.30 | $0.82 |
| 8 | RTX 4070 Ti | 150 TH/s | 230 W | $126.56 | $110.00 | $0.76 |
| 9 | RTX 4070 SUPER | 140 TH/s | 200 W | $118.12 | $103.72 | $0.82 |
| 10 | RTX 5070 | 136 TH/s | 250 W | $114.75 | $96.75 | $0.64 |
The leader is the RTX 5090 at about $339.18 per month. But it is also the most expensive and the most power-hungry card at 573 W. For most people the balance of income, card price and power draw matters more than maximum income, so below are an efficiency ranking and the best models in each budget.
Most efficient: income per watt
Efficiency shows how much income a card makes for every watt it uses. The higher it is, the less your electricity rate matters. The RTX 40 generation is unmatched here: with moderate power draw it earns as much as the power-hungry flagships of previous years.
| # | GPU | Hashrate | Power | Income / mo | Profit at $0.10 | Pays off up to, $/kWh |
|---|---|---|---|---|---|---|
| 1 | RTX 4080 | 220 TH/s | 255 W | $185.62 | $167.26 | $1.01 |
| 2 | RTX 4080 SUPER | 206 TH/s | 262 W | $173.81 | $154.94 | $0.92 |
| 3 | RTX 4070 | 120 TH/s | 163 W | $101.25 | $89.51 | $0.86 |
| 4 | RTX 4090 | 316 TH/s | 441 W | $266.62 | $234.87 | $0.84 |
| 5 | RTX 4070 Ti SUPER | 165 TH/s | 235 W | $139.22 | $122.30 | $0.82 |
| 6 | RTX 5090 | 402 TH/s | 573 W | $339.18 | $297.92 | $0.82 |
Look at the last column — the rate at which income equals the electricity cost. For the RTX 4080 it is $1.01 per kWh, while for the RTX 3090 it is $0.40: for the same income, RTX 40 spends far less on electricity.
The best GPU in every budget
Entry level: RTX 3060, RTX 4060, RTX 5060
The RTX 3060 12 GB is one of the most popular gaming cards, and it earns about $42.19 per month. The RTX 4060 earns more — about $52.31 — while drawing only 115 W, so it barely shows on the electricity bill. The RTX 5060 makes about $60.75. If one of these is already in your PC, it definitely makes sense to let it work while you are not gaming.
Mid-range: RTX 4060 Ti, RTX 5060 Ti, RTX 4070
The RTX 4070 is the best balance in the whole catalog: about $101.25 per month at just 163 W. The RTX 5060 Ti 8 GB earns about $74.25, the RTX 4060 Ti 8 GB about $65.81. For anyone choosing a card for both gaming and mining, this is the sweet spot.
Upper mid-range: RTX 4070 SUPER, RTX 5070, RTX 4070 Ti SUPER, RTX 5070 Ti
The RTX 4070 SUPER earns about $118.12 per month at 200 W, one of the most efficient cards in the catalog. The RTX 4070 Ti SUPER makes about $139.22, the RTX 5070 Ti about $150.18.
High end: RTX 4080, RTX 4090, RTX 5080, RTX 5090
The RTX 4080 earns about $185.62 per month at only 255 W — the best efficiency among the flagships. The RTX 4090 makes about $266.62, the RTX 5080 about $192.37 and the RTX 5090 about $339.18. Buying a top-end card just for mining means a long payback, but if you need it for gaming or work anyway, mining noticeably lowers its real cost.
Older cards: RTX 20 and RTX 30
Every RTX card since the 20 series has tensor cores, so even cards from 2018–2020 can mine. The RTX 3080 10 GB earns about $90.28 per month, the RTX 3070 about $59.06 and the RTX 2060 about $28.69. The downside of older generations is higher power draw: their electricity break-even point is lower than for RTX 40 and RTX 50, so run the numbers carefully if your electricity is expensive.
Since FlowHash 2.0, AMD Radeon RX 6000, RX 7000 and RX 9000 cards mine Pearl too. They have no tensor cores, so for the money they usually deliver fewer TH/s: the RX 9070 XT does about 100 TH/s, the RX 7900 XTX about 47 and the RX 6700 XT about 14 (estimates from public benchmarks; every card is in the calculator). Older cards mine too: NVIDIA GTX 10xx/16xx (GTX 1050 Ti, 1060, 1660 and so on) and Radeon cards with 3 GB or more — RX 470/480/570/580, RX 5000, Vega; they earn noticeably less, and the app shows the exact figure after picking the best miner. Only GTX 900 and older, 2 GB Radeon cards and Intel Arc are not supported — on such PCs you can mine Monero on the CPU.
Laptops
Laptop RTX GPUs run at a limited power level but are very economical: the RTX 4060 Laptop earns about $50.62 per month at 100 W, the RTX 4070 Laptop about $60.75. The real hashrate depends on the power limit and cooling of the specific laptop. FlowHash pauses mining on overheating and on battery power.
What to look for besides income
- Cooling. Models with a large heatsink and three fans keep temperatures and noise lower — for hours of continuous work that matters more than a couple of percent of hashrate.
- Power supply. Leave 20–30% headroom over the total system power draw.
- Payback. Divide the card’s price by its net monthly profit to get the payback period in months. Prices and coin rates change, so recalculate before buying.
- Gaming. If you also need the card for games, choose it for games: mining in your spare time will pay back part of the cost.
How to keep a card in good shape during long sessions is covered in “Does mining damage your GPU?”.
Bottom line
The RTX 5090 and RTX 4090 lead on income. For the balance of income and power draw, pick the RTX 4070, RTX 4070 SUPER or RTX 4080. Any RTX already in your computer is fine to start with: even the RTX 3060 12 GB earns about $42.19 per month. The mining calculator shows what your card will make at your electricity rate.
