Radiant (RXD) is Currently the Most Profitable Coin to Mine on GPUs
According to the GPU profitability ranking on the What to Mine website the Radiant (RXD) crypto is currently the most profitable coin to mine on most GPUs thanks to the recent spike in popularity and price. It is the top coin in profitability for almost all Nvidia GPUs and some AMD ones with Kaspa (KAS) also finding its spot in number two and three in terms of profitability on some and Alephium (ALPH) as well as some other coins jumping in from GPU to GPU. Do note however that depending on your custom settings you might be able to achieve even better profitability thanks to increased performance or decreased power usage or both. We have some guides you can check out for optimizing performance and power usage for both RXD and KAS that might be of help here, regardless if you are mining and holding or selling the mined coins immediately.
Both KAS and RXD are using different GPU-intensive mining algorithms for their Proof of Work (kHeavyHash and SHA512256d), so they key optimizations you can do for achieving lower power usage with maximum performance include lowering the memory to the minimum frequency supported, increasing the GPU clock together with a core clock offset to lower the voltage and the result is quite big improvement in terms of power efficiency while maintaining very high performance. Give it a try if you still haven’t and are already mining Kaspa or Radiant or are planning to do so switching form Ethash/ETChash mining for instance.
