According to the portal AdoredTV, the previously published report on the high energy efficiency of the Radeon RX 6600 XT video card in Ethereum mining is not entirely accurate. The card really shows itself well in cryptocurrency mining, but not as good as it might seem at first glance.
Previously, a user Dizzy Mining posted a video on his YouTube channel in which he described a method for optimizing the MSI Radeon RX 6600 XT Gaming X 8G graphics accelerator for mining. He lowered the GPU frequency to 1.2 GHz and increased the memory frequency of the card to 2.2 GHz, as a result, reducing its power consumption to 55 W and at the same time getting a performance of 32 MH / s when mining Ethereum.
Referring to the user Uzzi38, the AdoredTV portal reports that in the report Dizzy mining one moment is not taken into account. Unlike NVIDIA graphics cards and older AMD graphics cards, the new series of Radeon RX 6000 graphics accelerators does not report the Total Board Power (TBP) in software that describes the characteristics of graphics cards. Instead, for video cards of the new Radeon series, the so-called ASIC power is indicated, that is, the power consumption of the graphics chip of the video card, as well as the GDDR6 video memory.
The numbers in the screenshots here are flawed. AMD’s in-driver power readings are not full board power, they’re GPU die (core + SoC + IMC) + GDDR6 power.
The 6600XT figures here are like probably 35-40W below what they actually should be in reality. https://t.co/jSjINJ6Rr3

Portal AdoredTV decided to independently test the performance of the Radeon RX 6600 XT in mining and used the optimization settings that were suggested by Dizzy Mining in his video. As it turned out, in fact, the Radeon RX 6600 XT consumes 75W when mining Ethereum. Thus, its performance ratio per watt (PPW) is 0.42666, which is similar to the Radeon RX 6800 and Radeon RX 5700 XT models.
