In terms of mining Ethereum, the RX 6600 XT 8GB and GTX 1660 Ti 6GB are on par with each other, giving a mining efficiency of around 43%. However, there are a lot of other Ethash-based algorithms. For example, if Ethereum Classic suddenly rose in value, these two cards can still be considered sufficient. Basically, the RX 6600 XT 8GB and GTX 1660 Ti 6GB offer adequate mining performance in various Ethash-based algorithms. In Flux mining, the two cards offer similar mining efficiency once again.

For Ravencoin mining, the RX 6600 XT 8GB takes the lead, but the difference between the two cards isn’t a lot. Considering that the GTX 1660 Ti 6GB is much cheaper than the RX 6600 XT 8GB, the slight difference in mining efficiency isn’t that big of a deal. If the price of the GPU isn’t very important, you may opt for the RX 6600 XT, which offers a little bit higher mining performance.

If you are looking to dual-mine Ethereum and Alephium, the RX 6600 XT 8GB is the better card as it gives higher mining efficiencies than the GTX 1660 Ti 6GB. For those mining Firo, the RX 6600 XT 8GB is also slightly more efficient than the GTX 1660 Ti 6GB.

If you are mining Conceal, you should get the RX 6600 XT 8GB. The architectural improvements allowed the RX 6600 XT 8GB to more efficiently mine Conceal than the older GTX 1660 Ti.

For those interested in Ergo mining, you may opt for the GTX 1660 Ti 6GB, which is a bit more efficient than the RX 6600 XT 8GB. However, it would be better if you went for the better cards, such as an RTX 3060 or higher, as they would give you enhanced hashrates. For Aion mining, the GTX 1660 Ti 6GB is the better option due to the higher mining efficiency. In general, the NVIDIA cards offer better Aion mining performance than AMD cards.

If you want to mine Cortex, the RX 6600 XT takes the win here. The GTX 1660 Ti 6GB does not have enough memory to mine Cortex and will give an error. To mine Cortex, you will need at least 8GB of memory. On the other hand, if you are looking to mine Conflux, the GTX 1660 Ti 6GB is the winner as the RX 6600 XT cannot mine this coin and will give out an error as there is no miner support. Hence, if you are focusing on either of these two coins, you may simply ignore the card that cannot mine the coin of your choice.

You can choose either of the two cards depending on the coin of interest. However, regardless of your choice, you will be getting your hands on a decent GPU for mining. Thus, if you are looking to mine any of the algorithms above, it might be a good idea to get your hands on a few of these cards right now!
