The newly launched graphics card from AMD, Radeon RX 6600 XT, could turn out to be an interesting card for cryptocurrency users, as it seems to be the best mining GPU beating the GeForce RTX 3060 Ti and RTX 3070 of Nvidia by a little margin.
AMD Radeon RX 6600 XT could be the most efficient GPU for Ether mining
According to a report from Reddit, the AMD Radeon RX 6600 XT offers 32 MH/s performance in Daggerhashimotto (Ethereum) at just 55 watts. No other card can boast this power-to-power ratio, and none offers such a low power consumption.
The AMD RDN2 graphics chips are not widely used for mining because of their price and inferior mining performance compared to Nvidia Ampere graphics chips. In addition, the RDNA2 graphics card has shorter memory buses, which has the greatest impact on lower mining performance than the competition.
However, the whole situation seems to be different with the Navi 23 GPU. The Radeon RX 6600 XT with 2048 stream processors and 8GB of GDDR6 memory in 128-bit is surprisingly good at mining Ethereum.
The Radeon RX 6600 XT only offers 32 MH/s at Daggerhashimotto, which is not a noteworthy value, but such performance at just 55 watts is surprising to see. The wattage is most impressive here, as there is hardly any other card capable of delivering such high mining performance at low power.
In terms of mining performance per watt, the Radeon RX 6600 XT has a significant advantage over any graphics card that has been prized in the mining segment. It is also worth mentioning that the price of Ethereum has been increasing in the last couple of weeks, which is at $3,262 in the last three months. So it definitely means that Ethereum has become the most profitable cryptocurrency for miners.
