Depending on the manufacturer, Radeon RX 6600 XT clock rates may vary from model to model. However, the cards should work in much the same way before moving on to operations capable of maximizing its potential. For example, an ASRock RX 6600 XT Phantom Gaming OC with default settings is capable of reaching 28MH / s in Ethash, but, with a little optimization and overclocking of the GDDR6 memories, a hash rate of 32MH / s can be achieved. .
If we focus solely on the hash rate, the Radeon RX 6600 XT doesn't look impressive at all, considering we can get similar mining performance on a Radeon RX 570 or RX 580 with a few adjustments. However, the Polaris-based graphics card draws more power, and this is where the Radeon RX 6600 XT really excels. While the Radeon RX 570 or RX 580 can draw over 130W, the Radeon RX 6600 XT has kept its power consumption within the margin of 75W, but it is possible to lower this further depending on the model and the use of some particular settings.
This leads the Radeon RX 6600 XT to be much more efficient than other RDNA 2 models, such as the Radeon RX 6800, or the GeForce RTX 3060 (this before NVIDIA integrated an Ethereum hash rate limiter) .
