Mining on NVIDIA GeForce RTX 3080: profitability | Hashrate | Specs – As soon as Zhen-Sun Huang or Lisa Su announce the release of a new line of video cards, miners perk up their spirits talking about the new “king of mining” and the killer of ASICs. Although, to be honest, old models such as Rx 570 (8GB) and GTX 1080 Ti still remain relevant devices for assembling mining farms.
Today we will talk about another miracle of technology from the company Nvidia rtx 3080. Mining on this video card seems to promise a high profit and unfortunate gamers are panicking about the soaring prices. In their opinion, the root of all evil is mining. The card 3080 is so coveted and desired by the gamer, it can be captured by the evil gnomes and disappear in the cryptomines. “We are going to the Crusade. A good miner is a dead miner, ”they scream at every site.
Well, okay, we’re not talking about them now, but about the new green GeForce RTX 3080 video card and its effectiveness in mining cryptocurrencies.
RTX 3080 Graphics Specifications
Let’s first look at the technical parameters of the gpu rtx 3080 in order to understand why Zhen-Sun Huang and the company is pulling so much money from us, and why the first batch of these cards was crushed in a matter of hours. For clarity, let’s compare the new model with the previous flagship rtx 2080.

| Process technology (nm) | 8 | 12 |
| Transistors (million) | 28300 | 13600 |
| Core frequency, MHz | 1440–1710 | 1515–1710 |
| Shader unit frequency, MHz | 1440–1710 | 1515–1710 |
| Shader blocks | 8704 | 2944 |
| TMU | 272 | 184 |
| ROP | 96 | 64 |
| Memory frequency (DDR), MHz | 1188 (19000) | 1750 (14000) |
| Memory bus | 320-bit | 256-bit GDDR6 |
| Memory type | GDDR6X | GDDR6 |
| Memory size | 10240 | 8192 |

| DirectX | 12 (12_2) | 12 (12_1) |
| Interface | PCI-E 4.0 | PCI-E 3.0 |
| Power, W) | 320 | 240 |
The characteristics are, of course, impressive. It can be seen that the employees of Nvidia wanted to surprise their customers and they succeeded.
Which is better to choose, GeForce RTX 2080 or RTX 3080
Judging by the data from the table, the card of the new line is almost twice as powerful as the 2080, while the power consumption has not grown so much. Moreover, if the essence of the site e-katalog.ru models do not differ much in cost.
Of course, it’s better to take a new, higher-performing model. However, when a larger batch of new cards is delivered and they fill the counters, the cost of their predecessors is likely to go down. In addition, Nvidia has other models, for example, 3 1660 Super cards produce about 95 Mh / s, at 215w consumption, and cost $ 700. But let’s check how many 3080 mines per day. Does it really double the RTX 2080?
Test RTX 3080 in mining on different algorithms
As they write about the RTX 3080 on the miningclub.info forum: “Only two Kolki have these cards, the rest all Chinese miners bought in bulk“. Therefore, we will trust what the happy owners of the new “mining kings” have published.
The title of the first publication looks like this: “Palit RTX 3080 GamingPro and Ether Mining = 100 mh at 240w”. Well, quite good, the consumption of 3080 in mining, with this hashrate is not very high. For comparison, the RTX 2080 card consumes 160 watts, at a hash rate of 40 Mh / s… Some miners claim that even these indicators are not the limit. You just need software optimized for a new type of memory, and even now the Innod3080 card can be overclocked to 115 Mn / s… However, no spoilers were attached to the commentary.
Tests on other algorithms have not been carried out, and it is unlikely that mining on MimbleWimble, Eqihas or KawPow will be more profitable than on Ethash. At least until the full-fledged Ethereum 2.0 network is launched and the mining reward is cut. Then rush to try, and how many 3080 mines per day on a raven, a smile and a ray. True, on the same miningclub.info there is a publication whose author claims that 3080 does not mine anything except algorithms Ethash and RandomX (Currency), you can go to this forum page here.
But nevertheless, there is no need to rush to conclusions, probably, it is in the software. When miners have more new cards, the developers will release compatible crypto mining applications.
How to Overclock RTX 3080 and Reduce Power Consumption
Well, what kind of overclocking is needed for the rtx 3080 to reach 100 Mh / s, because judging by publications from various sources, the card produced much more modest results at the factory settings (somewhere around 75-80 Mh / s). As the author of the publication writes, and this is the forum moderator known by the nickname ValeraTV, for efficient mining on the RTX 3080, you need to set the following overclocking parameters:
- Power Limit 75;
- Core Clock 0;
- Memory Clock 1000.
Tests were carried out on a Palit RTX 3080 GamingPro video card. The RTX 3080 VENTUS X3 was overclocked to 103 Mh / s with the following parameters:
- Power Limit 76;
- Core Clock 0;
- Memory Clock 1500.
Link to the source of information https://miningclub.info/threads/vse-rtx-3080-10gb-v-majninge.70017/. I must say that not every RTX series gpu can be overclocked so much from memory, with a rather low power limit. But, on the other hand, the graphics adapters from the green themes are good because you don’t need to mess with them for a long time when setting up mining, moved a couple of sliders and you’re done.
Of course, for advanced miners you can use Nvidiainspector, but with the RTX 3080, this program is most likely not friendly yet. You can try to reduce the voltage in the MSI Afterburner program using Curve on the website overclockers.ru they claim that they were able to achieve minus 50 watts, and reduce heat transfer without sacrificing performance. It took the following steps in the OC Scanner application:
- Decrease the base frequency of the core by 291 MHz.
- Increase the frequency in the selected voltage coordinate (800 mV) by 240 MHz.
- Apply modified metrics in MSI Afterburner.

Conclusion, relevance of investment
Let’s calculate the profit and decide whether to buy an rtx 3080 for mining. As of 02/11/2021, a card with a hash rate of 100 Mn / s on ETH brings $ 10.29 excluding the socket. That is, a mining farm of four RTX 3080 graphics adapters will work approximately 42$ net profit per day.
Of course, the result will depend on the cost of electricity in your area and other circumstances. It takes about $ 10,000 to equip such a farm, which means the payback period is 8 months… Although in reality it can take a year and a half, or it can be halved.
On thematic forums, miners argue which is more profitable to buy one 3080 card or three 1660Super cards for mining. Both sides have many compelling reasons, but nevertheless, gpu devices of the new line are more promising, since their capabilities have not yet been revealed. Greens have a new contender for the throne of the “king of mining” let’s see how the Reds will respond.
