AMD’s RX Vega 64 Gets 43.5 MH/s At 248 Watts of Power Draw

The latest power efficiency claims of the AMD Vega 64 graphics card have been circulating around the internet, and there are reports that it outperforms its competitors in terms of mining efficiency. The Vega 64 was reportedly able to achieve a hash power efficiency of 43.5 mHash/s on a power draw of 130 watts for Ethereum Classic (ETC) mining. This translates to a hashing power efficiency of 0.33 mHash per watt, which is significantly higher than the initial power efficiency of the Vega 64 and surpasses the efficiency of the GTX 1070.

However, a closer examination of these claims has revealed some discrepancies. Independent testing using a Vega 64 (liquid cooled edition) and a watt meter showed different results. While the Vega 64 was able to achieve the 43.5 mHash/s rate, the power draw from the wall was significantly higher than reported, measuring at 386 watts under full load. This resulted in a power efficiency of roughly 0.175 mHash per watt, which, while impressive, did not match the claimed 0.33 mHash per watt.

It’s worth noting that the reported power efficiency might have been achieved using proprietary mining software or custom mining rigs, which are not accessible to the average consumer. While professional miners may be able to achieve higher power efficiency through customized code, mainstream miners and average consumers should approach such claims with caution.

Despite this, the Vega 64’s performance in real-world mining applications is still highly commendable and could contribute to sustained demand for the card. The high hash rate and competitive efficiency make it a valuable asset for mining operations, which may in turn influence the card’s market price.

In light of these findings, it’s important for consumers to critically evaluate claims of extreme power efficiency in mining and consider real-world testing and practical applications when assessing the value of hardware for mining purposes.
