AMD's Radeon RX 6600 Non-XT releases in a couple of weeks and we have obtained the first mining performance results in Ethereum for the latest RDNA 2 graphics card.

From what we have learned, our sources at certain retailers have already got access to the Radeon RX 6600 graphics card and have provided mining performance results in Ethereum using the BETA AMD drivers. Back in August, we got to see how the AMD Radeon RX 6600 XT managed to offer an insane amount of efficiency within Ethereum mining, & well, the numbers for the Radeon RX 6600 take that lead even further.
