*At the moment, voltage adjustment for the RTX 5080 GPU is unavailable, so higher energy efficiency in mining on these cards may be achievable in the future.
The transition to GDDR7 not only delivered excellent results in memory-dependent mining algorithms (such as Ethash) but also reduced the thermal load on the memory compared to GDDR6 and especially GDDR6X. During testing, the temperature of the GDDR7 memory on the RTX 5080 rarely exceeded 70 degrees Celsius, which will significantly improve the reliability of this series of graphics cards. For comparison, GDDR6X memory in mining often heated up above 100 degrees.

Conclusion
The RTX 5080 offers a new level of performance in mining, primarily due to the new GDDR7 memory standard, which provides a real performance boost on algorithms like Ethash, KawPow, and other memory-dependent algorithms. The GPU itself also delivers a noticeable increase in hashrate, albeit with higher power consumption compared to the RTX 4080. In any case, the GPU remains powerful enough to use this card for dual cryptocurrency mining, where it can demonstrate its maximum return on investment.
The Nvidia GeForce RTX 5080 is definitely worth recommending for cryptocurrency mining, but as always, the decision should be based on the price of the graphics cards. Often, discounts on previous-generation models can outweigh the advantages of new releases.
