AMD Radeon RX 6600 XT the greatest mining card ever?

Today marks the availability date of AMD's Radeon RX 6600 XT. It's the cheapest RDNA2-based video card to date but there may be trouble on the horizon as VideoCardz came across evidence that AMD's newest card may be the best cryptocurrency mining video card to date.

Futher analysis will be needed to confirm it, but it seems the Radeon RX 6600 XT achieves very great Ethereum mining efficiency. The hashrate of the card isn't that great but with a power consumption of just 55W, the card is a lot more efficient at mining Ethereum than the Radeon VII, the second most efficient model.

According to the video made by Dizzy Mining, who had used MSI RX 6600 XT Gaming X, the card offers 28 MH/s at 93W out of the box. After reducing the maximum GPU frequency to 1.2 GHz and increasing memory frequency to 2.2 GHz, mining performance increased to 32 MH/s while TDP dropped to 55W (GPU ASIC Power).

It will be interesting to see how this will affect retail availability of this $349 card.
