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.

Must read: The Best Motherboards for Mining Bitcoin and Ethereum 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: EVGA GeForce RTX 3090 FTW3 ULTRA Gaming

  • 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 104.70 MH/s hashrate on Ethash (Phoenix) algorithm, and can generate an impressive monthly income (according to Besides being a fantastic mining GPU, the GeForce RTX 3090 is also great for 4K gaming, as well as 3D modelling, video rendering and ray-tracing rendering. Provided you can grab yourself one, getting an RTX 3090 is a no-brainer if you want to make some serious money by mining cryptocurrencies.

Best Multi-Purpose: Gigabyte GeForce RTX 2080 Ti Gaming OC

Boost Clock: 1665 MHz | Memory: 11GB GDDR6 | Length: 304 mm | Power Connectors: 2 x 8-pin | Outputs: 3 x DP, 1 x HDMI, 1 x USB Type-C

  • Fantastic performance
  • Very efficient cooling system
  • Consumes less power than RTX 3080
  • Three huge fans
  • Hard to find at MSRP in today’s wild GPU market

Although nowadays quite expensive, the GeForce RTX 2080 Ti is an amazingly powerful graphics card. Featuring 11 GB of GDDR6 memory, and a total number of 4,352 CUDA cores, the RTX 2080 Ti is one of the best graphics card for mining Firo (FIRO) coin. Capable of delivering 50.06 MH/s on Ethash (Phoenix) algorithm, a single RTX 2080 Ti card can generate a healthy monthly income. The RTX 2080 Ti is also an awesome card for gaming, CAD designing and content creation, and can pay itself off very quickly if you know how to put it to good use. This particular model from Gigabyte features 7% higher boost clock than the reference model, and it comes with a separate USB Type-C connector.

Bargain Powerhouse: ASUS Radeon RX 5700 XT 8GB TUF X3 OC

Boost Clock: 1980 MHz | Memory: 8GB GDDR6 | Length: 269 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 operating 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 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 deliver great performance, making it thus an excellent choice for cryptocurrency miners with a more modest budget.

Best for Beginners: XFX Radeon RX 5500 XT Thicc II Pro

Boost Clock: 1845 MHz | Memory: 8GB GDDR6 | Length: 281 mm | Power Connectors: 1 x 8-pin | Outputs: 3 x DP, 1 x HDMI

  • Amazing compute performance
  • Great mining hashrate
  • Supports PCIe 4.0 bus interface
  • Affordable price
  • Unimpressive performance in gaming
  • Not much faster than the last-gen RX 580

The AMD Radeon RX 5500 XT is probably the best graphics card for cryptocurrency mining beginners. For its price, the Radeon RX 5500 XT is able to offer 8 GB of very fast GDDR6 VRAM, full support for PCIe 4.0 bus interface, and a whooping 10.39 TFLOPS of FP16 (half) performance. When it comes to mining, this card can deliver up to 30.00 H/s hashrate on Ethash (Phoenix) algorithm, or up to 480.50 H/s on XMR (RandomX) algorithm, which can secure you a decent monthly income. This way, by purchasing two of these cards you can start generating almost the same monthly income as if you owned a single GeForce RTX 2080 Ti, but for less money. Overall, the RX 5500 XT is not a particularly powerful gaming graphics card, but its impressive compute performance makes it one of the best graphics cards for starting a crypto mining business.

Budget King: 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
  • Good mining performance
  • Low power draw
  • Features only 4GB of VRAM
  • Weak for serious gaming and productivity

The AMD Radeon RX 570 is old but gold GPU. 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 23.00 MH/s hashrate on Ethash (Phoenix) 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 owned a single GeForce RTX 3080. Although this may not sound 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.
