"Conclusion: In all technical and economic parameters, the Geforce RTX 3060 video card loses to the RTX 3060Ti, primarily in terms of price, i.e. the technical characteristics of the video card turned out to be much lower than the company Nvidia established the difference in price between these two models of video cards. And when choosing between these two models, you should give preference to the RTX 3060Ti. But the younger model still has a couple of advantages: more memory, which may come in handy in the future for mining algorithms that require a large amount of memory and only one additional power connector, which simplifies the assembly of mining rigs and the selection of power supplies."
