  The Nvidia 3090 consumes significantly more power than the 3080 when it comes to mining digital currencies. The 3090 has a higher power draw due to its increased number of CUDA cores and higher clock speeds. This means that it will consume more electricity and generate more heat compared to the 3080. It's important to consider the power consumption of these GPUs when setting up a mining rig to ensure that you have sufficient power supply and cooling capabilities.

  The power consumption difference between the Nvidia 3090 and 3080 for mining digital currencies is quite noticeable. The 3090 has a higher TDP (Thermal Design Power) of 350W, while the 3080 has a TDP of 320W. This means that the 3090 consumes around 30W more power than the 3080. It's important to factor in the electricity cost when deciding which GPU to use for mining, as the higher power consumption of the 3090 can significantly impact your profitability.

  According to my research, the power consumption difference between the Nvidia 3090 and 3080 for mining digital currencies is approximately 10%. The 3090 consumes around 10% more power compared to the 3080. However, it's worth noting that the 3090 offers higher mining performance due to its increased CUDA cores and memory bandwidth. So, even though it consumes more power, it can potentially provide a higher hash rate and better mining efficiency.
