AMD Radeon RX 6600 XT is actually good in cryptomining
AMD’s just-released mid-range RX 6600 XT might be at risk from crypto miners.
With Ethereum value increasing, the last thing gamers want to hear is that miners are interested in another GPU launch. According to the report from Reddit, AMD RX 6600 XT appears to be quite good in mining, offering impressive mining efficiency compared to other products. The data shared on the platform is based on preliminary data and speculation, which is why we decided to do more digging.
AMD RDNA2 GPUs are not commonly used for mining due to their price and relatively worse mining performance compared to NVIDIA Ampere GPUs. More importantly, RDNA2 GPUs have shorter memory buses, which affects mining performance the most.
This might not be the case with Navi 23 GPU though. The Radeon RX 6600 XT with 2048 Stream Processors and its 8GB GDDR6 memory across a 128-bit interface is already good in mining. According to the video made by Dizzy Mining, who had used MSI RX 6600 XT Gaming X, the card offers 28 MH/s at 93W (ASIC) out of the box. After reducing the maximum GPU frequency to 1.2 GHz and increasing memory frequency to 2.2 GHz, mining performance increased to 32 MH/s while TDP dropped to 55W (GPU ASIC Power, which does not account for the whole graphics card power).
Tom’s Hardware also made their own test, which confirms that RX 6600 XT is indeed a good card for mining. They provide actual graphics card consumption figures measured through the Powenetics hardware monitoring tool. It reports an average of 75W of actual power consumption of the whole graphics cards.
