AMD’s Radeon RX 6600 is finally available across retailers around the world. The overall reception to the budget Navi 2x part has been mixed, but the supply seems to be holding up. Multiple mining channels have tested the card and reported the hash rate of the card. Unsurprisingly, the 6600 performs much worse than the RX 5600 XT in Ethereum mining on account of its slimmer bus.
With an average Ether hash rate of just 23 MH/s, the Radeon RX 6600 is a terrible card for miners, either way, you look at it. Even after a fair bit of tuning, you can only increase the hash rate to just over 25 MH/s. That’s pretty much the same as a stock RTX 3060 LHR. The vanilla RTX 3060s could manage a healthy 40 MH/s at the very least. Even the older Radeon RX 5600 XT could easily push 40 MH/s at stock.
The power consumption is modest, almost enough to ignore the bleak hash rate. Under stock conditions, the RX 6600 drew 87W of power while tuning the clocks dropped it to just 55W. As expected, the temperatures were also pretty decent, staying under 70 degrees with a fan cycle of just 35%.
