Comparison of AMD 6900 XT vs RTX 3080/3090 in mining
In February 2021 it was like this:
| ETH hashrate | Consumption | USD \ Day | A source | |
| RX 6800 XT | 64 MH/sec | 160 Watt | 6,23 | [ BitsBeTrippin ] |
| RX 6900 XT | 64 MH/sec | 154 Watt | 6,23 | [ DizzyMinning ] |

Overclocking 6900 XT and 6800 XT for Ethereum mining
Overclocking through Radeon Software following the example of reviewers and miners. Before starting overclocking, turn off MSI Afterburner and do not turn it on again. After overclocking, we fix the indicators for the farm, and in order not to lose, press CTRL + D and add this page to your bookmarks.
Specify the following parameters through Radeon Software. [ How to do it ].
- 6800XT : 1400 core frequency / 881 mv voltage per core / 2150 memory frequency
- 6900XT : 1100 core frequency / 825 mv voltage per core / 2088 memory frequency
At the output, we get an average of 64 MH / s per card. The difference in the number of cores and texture units does not help the cards, but the older model gets its 64 MH / s at a core frequency of 300 MHz lower than that of the RX 6800 XT. Consequently, it will be more energy efficient than the younger model.

Conclusion on the RX 6800 XT and RX 6900 XT cards
For gaming: 6800 XT> 6900 XT. For mining, it is better to take the 3000 series from NVIDIA, if possible. In the absence of this, AMD 6000-series cards with the XT index will be a good alternative. However, they should be taken only when the price of the models of this line falls, so as not to overpay to retailers.
