In the last quarter of 2020, Bitcoin (BTC) and Ethereum (ETH) cryptocurrencies experienced some serious price growths. This made cryptocurrency mining a profitable business once again, and caused an increased demand for crypto mining hardware. In this quick guide, we’ll take a look at the best graphics cards for crypto mining in 2021.
For mining cryptocurrencies, such as Bitcoin or Ethereum, you don’t have to own a high-end graphics card. Of course, having the more power means you’ll able to generate more money quicker, however, if a graphics card comes with a high price tag, that doesn’t necessarily mean it will perform good in crypto mining. Good mining GPUs need to have enough power and memory to perform numerous calculations simultaneously, while at the same time be as much energy efficient as possible to be profitable. Some of the key metrics that determine whether a GPU is good for mining are its compute performance, and hashrate. The higher these two values are, the better will the card be at mining.
In the past few months of 2021, mining cryptocurrencies has become an extremely profitable business. This is why finding brand new graphics cards in stock has become very difficult, since demand for them is incredibly high. However, this doesn’t mean it’s too late to start mining, In fact, you still have good chances to make some serious money in this business. Provided that you start mining today, in the near future you might be able to make a small fortune if prices of cryptocurrency coins keep growing. However, in order to do that, you’ll need to buy a capable graphics card. Here are our top picks for the best cryptocurrency mining GPUs in 2021.
Best Overall: MSI GeForce RTX 3060 Ti Gaming X Trio
Boost Clock: 1830 MHz | Memory: 8GB GDDR6 | Length: 323 mm | Power Connectors: 2 x 8-pin | Outputs: 3 x DP, 1 x HDMI
- Outstanding mining performance
- Suitable for mining multiple algorithms
- Great power efficiency
- Supports DLSS 2.0 and ray-tracing
- Difficult to obtain
The NVIDIA GeForce RTX 3060 Ti is without a doubt the best mining graphics card right now. It has one of the highest efficiencies on the market, as it’s capable of delivering 58.1 Mh/s hashrate on Ethash algorithm for a total power draw of only 130 W. In addition, it is also a very good all-round card, since it can mine many other algorithms as well. The GeForce RTX 3060 Ti can also boast with its 4,864 CUDA cores, as well as 8GB of super-fast GDDR6 memory. Compared to the RTX 3090, and the RTX 3080, this card features a significantly better ROI, and as such is a perfect choice for most miners. Unfortunately, it is very hard to come by, due to incredibly high demand for it.
Quickest ROI: ZOTAC Gaming GeForce GTX 1660 SUPER
Boost Clock: 1785 MHz | Memory: 6GB GDDR6 | Length: 174 mm | Power Connectors: 1 x 8-pin | Outputs: 3 x DP, 1 x HDMI
- Affordable price
- Low power draw
- Runs quiet and cool
- Doesn’t support ray-tracing
- Only suitable for mining Ethereum
If you don’t have too much money to invest into cryptocurrency mining, and want something with a quick return on investment (ROI), then you may find NVIDIA GeForce GTX 1660 SUPER very appealing. This graphics card isn’t as powerful as its other brethren from the NVIDIA RTX lineup, however, it features a very good power efficiency, and a decent mining hashrate. A single GTX 1660 SUPER can deliver 30 Mh/s on Ethash algorithm for a total power draw of only 90 W, or 4.30 h/s on CuckooCyle algorithm. Two of these cards can thus deliver the same mining performance as a single RTX 3060 Ti for roughly the same amount of money. But, besides being more affordable, the GTX 1660 SUPER is also much easier to find in stock, which is another plus.
Bargain Powerhouse: AMD Radeon RX 5700 XT 8GB
Boost Clock: 1905 MHz | Memory: 8GB GDDR6 | Length: 272 mm | Power Connectors: 1 x 8-pin + 1 x 6-pin | Outputs: 3 x DP, 1 x HDMI
- Great compute performance
- Supports AMD FreeSync
- Supports PCIe 4.0 interface
- No ray tracing acceleration
- High working temperatures
The AMD Radeon RX 5700 XT is a very affordable graphics card for serious cryptocurrency entrepreneurship that offers reasonably quick ROI. Besides bringing 1440p gaming on ultra settings to the mainstream, this is an exceptionally powerful graphics card for hashing out blockchains. Featuring FP16 compute performance of whooping 19.51 TFLOPS, this card is able to deliver a hashrate of 50.45 Mh/s on Ethash (Phoenix) algorithm, and is able to generate almost the same monthly income as the GeForce RTX 2080 Ti. Compared to its NVIDIA counterpart, the RX 5700 XT does tend to run hotter and consume more power, but it also costs less. Despite the fact that it lacks ray tracing features, this is still a very good graphics card that is able to offer great performance, making it thus an excellent choice for cryptocurrency miners with a more modest budget.
Ultimate Performance: EVGA GeForce RTX 3090 FTW3 ULTRA Gaming
Boost Clock: 1800 MHz | Memory: 24GB GDDR6X | Length: 300 mm | Power Connectors: 3 x 8-pin | Outputs: 3 x DP, 1 x HDMI
- Extraordinary high hashrate
- Absolutely crazy performance in 4K and 1440P gaming
- Great for 3D modelling and video rendering
- 35% faster than the GeForce RTX 2080 Ti
- Requires 750 W power supply
- Triple-slot design
NVIDIA GeForce RTX 3090 is without a doubt the best mining GPU right now. Featuring mind-blowing 10,496 shading units, 328 Tensor Cores and 24 GB of super-fast GDDR6X VRAM, this card can deliver a 114.00 Mh/s hashrate on Ethash (Phoenix) algorithm, and can generate an impressive monthly income (according to betterhash.net). Besides being a fantastic mining GPU, the GeForce RTX 3090 is also great for 4K gaming, as well as 3D modelling, video processing and ray-traced rendering. Provided you can get yourself one, getting an RTX 3090 is a no-brainer if you want to make some serious money by mining cryptocurrencies.
Best Budget: ASRock Radeon RX 570 4GB Phantom Gaming D
Boost Clock: 1293 MHz | Memory: 4GB GDDR5 | Length: 236 mm | Power Connectors: 1 x 6-pin | Outputs: 3 x DP, 1 x HDMI, 1 x DVI
- Very affordable price
- Solid mining performance
- Low power draw
- Features only 4GB of VRAM
- Weak for serious gaming and productivity
The AMD Radeon RX 570 may be old, but is gold. It is also one of the best graphics card for miners on a tight budget. Featuring FP32 (float) computer performance of 5.09 TFLOPS, this GPU can deliver around 27.90 Mh/s hashrate on Ethash algorithm, but with custom BIOS mods, it can deliver up to 30.00 Mh/s. Although its retail price is currently greatly exaggerated, the RX 570 can pay itself very quickly, since this card offers very good ROI. Mining Ethereum with three of these cards will net you the same monthly income as if you used a single GeForce RTX 3080. Although this may not sound very impressive, keep in mind that it’s far easier to purchase three RX 570’s than to find a brand new RTX 3080 in stock. Even though it comes with only 4GB of VRAM, the RX 570 is able to offer enough performance to efficiently mine various cryptocurrencies, and its power draw is quite small so you won’t have to worry much about keeping track of your electricity bills.
Mining Ethereum and other cryptocurrencies has never been more popular. This has caused a great GPU shortage which we are now witnessing. However, this doesn’t mean that mining is no longer profitable. Provided that you equip yourself with some high-performance graphics cards, you still have good chances to make impressive amounts of money by mining Bitcoin and Ethereum.
