4GB VRAM graphics cards are not good for Ethereum mining because they do not have sufficient memory to run the GPU-intensive calculations of Ethereum mining. The current DAG size is 3.49GB for Ethereum and 3.58 GB for Ethereum Classic. This means that GPUs with 3 GB or less VRAM cannot mine it anymore.

Is Ethereum mining still profitable? Yes, mining Ethereum is still profitable – based on the mining hardware hashrate of 2,500.00 MH/s, electricity costs, and pool / maintenance fees provided.

According to Minerstat, each RTX 3080 graphics card can generate between 6.35 USD and 9.15 USD a day (that’s including electricity cost and assuming today’s Ethereum pricing). This means that the whole system can generate between 15K to 21K USD a month .

The card can be found in 3GB and 6GB configurations, while they won’t have a lot of differences in the mining hash power, the 3GB card aren’t compatible with Ethereum mining today. So if you want to mine Ethereum you should probably get the 6GB version .

27, the estimated daily profit for an Ethereum miner using a single GPU was $4.59 . For Feathercoin, by way of comparison, miners were estimated to lose $0.58 per day. Obviously, to generate a significant amount of profit, you’d need to host a large number of GPUs using these calculations.
