The AMD Radeon RX 6600 XT is an Ethereum miner’s dream with 32 MH/s with a minimal power output.
I have recently bought 3 of these and look to invest in more due to the efficiency of the cards and they keep temperature really well.
Personally, I love these cards as there is no need to BIOS update like other AMD cards and the thermals in my small GPU farm are fine – 23 cards and growing.

These cards are all close in terms of performance, so at this point I think it all depends on price and avoiding scalpers.
Ethereum miners have been drawn to NVIDIA’s GeForce RTX 30 series cards, but AMD now has a compelling option in the shape of the Radeon RX 6600 XT. The Navi 23 card is twice as efficient as a GeForce RTX 3060, thanks to a 32 MH/s hash rate.
If you need some overclocks – here are mine on HiveOS but you should be able to get these even better by editing the VDD, please only do so in small increments at your own risk.
Availability of the AMD Radeon RX 6600 XT remains strong, despite having just launched. Prices have not reached astronomical levels either, unlike with all other RDNA 2 and Ampere releases to date. However, the card could yet prove a decent option for crypto mining, even with its comparatively weak GPU.
According to initial mining tests, the Radeon RX 6600 XT manages 32 MH/s at 55 W when mining Ethereum, which still remains popular among crypto miners. To put those figures in perspective, the Radeon RX 6600 XT is about twice as efficient as the NVIDIA GeForce RTX 3060. In our opinion, the Radeon RX 6600 XT could become the most efficient crypto mining card of the RDNA 2 generation. The same should be the case for Ampere cards, too.
While we do not have any Radeon RX 6600 XT cards to hand, a video by Dizzy Mining has demonstrated that these values are achievable. By default, the RX 6600 XT will reach 28 MH/s while consuming 93 W. Dropping the GPU clock speed to 1.2 GHz and increasing the memory clock to 2.2 GHz improves the hash rate to 32 MH/s at 55 W, though.
Hence, the card could end up being a popular option for mining farms, which may push up prices. The Radeon RX 6600 XT is a good choice for 1080p gaming, too, with its Navi 23 GPU, 32 MB of Infinity Cache and 8 GB of GDDR6 VRAM running on a 128-bit interface.
