Can I mine Monero with a graphics card?

 Short answer - yes.

But for 95% of people it's not a good idea. Monero uses an algorithm called RandomX that is optimised to work best on CPUs. Mining with a GPU will get about 10% of the hashrate of a CPU, while still using the full power of the GPU. For most people it will cost a lot more for the electricity than you'll earn. And even if you have free electricity, you'll earn so little that it's not worth spending even $30 on a GPU for mining.

There are lots of old guides that advise mining with a GPU. There are from before monero switched to the RandomX algorithm so they no longer apply.

HOWEVER, there are some pools with automatic algorithm switching that let you mine a coin your GPU would be more profitable on. The pool converts it and pays you in monero. See here for a full guide on selecting a pool.

Assuming you're not using one of the algorithm switching pools, who should mine monero with a GPU?

  • If you have free electricity.
  • If you were going to use an electric resistive/convection heater but have a computer that can mine Monero instead to produce heat.

  1. Thanks for writing this. I'm looking at potentially GPU mining XMR or various other crypto, i have cheap electricity as well. Approx 3-4 dollars a day.

    Effective hash rate for the mining rig i'm putting together is 330MH/s

    Haven't checked if i do it via CPU and how much that would cost me.

    But based off of this blog post i've seen that using RandomX i won't get my 330 MH... is it just that RandomX doesn't like GPU's? Just trying to see what coin i can mine at an acceptable profit. Thanks!

  2. I have a RTX 3060 TI which reads 60MHs, and if I use a Monero calculator, the profit is ridiculous. Why does this happen?

  3. if mining using cpu is not profitable, then there is no reason for us to mine right? it would be better if you allow to mine using gpu.

  4. Thanks for the info.

    I currently mine Monero and will be accepting it as payment for my brick and mortar business opening very soon. Monero is fungible. Monero is the future.
