Is 6GB Graphics Card enough for mining?

First, Ethereum GPU mining requires more than 4GB of VRAM , so if you’re still hanging on to an RX 570 4GB, it won’t work — and neither will the new Radeon RX 6500 XT. Second, there are a lot of different software packages for mining, but we’re taking the easy route and using NiceHash Miner.

Bottom line: You don’t need the most powerful GPU to make a little mining crypto , and the NVIDIA GTX 1660 SUPER is a fine example of this. It’s got 6GB of speedy GDDR6 VRAM, a TDP of just 125W, and can comfortably achieve a hashrate of 26MH/s, all for a low price tag.7 Mar 2022

The GTX 1060 is a fairly good Ethereum mining card – not the best but quite competative and more efficient than many other options. It is NOT a “terrible” card for mining ETH, especially if you already have it.
