Mining with Radeon RX 6900 XT and RX 6800 XT: benchmarks, hashrate, consumption
The first tests showed that the 6800 XT showed [ terrible performance ] compared to 3080: 59 megahashes versus 86. The situation with the RX 6900 XT was a little better – out of the box it produced from 59 to 62 MH / s, and when overclocked it rose to 64 MH / s.
But there is one “but”. As of February 2021, there is no difference in mining between the RX 6800 XT and the RX 6900 XT. Both cards provide an equal number of megahashes with equal consumption and the same temperatures.
Hashrate and Consumption of RX 6800 XT
As with AMD cards, performance increases with the driver version number. This has been confirmed experimentally for the 6800 XT as well. Test stand:
- CPU: Ryzen 5 5600X
- GPU: PowerColor RX 6800 XT
- Motherboard : Asrock B550 / ITX / AC Motherboard
- Memory : 16GB Corsair LPX PC3600
- Диск: 1TB Samsung Pro980 NVME Gen4
Here it is, the most important photo in the article: in mining, an overclocked RX 6800 XT produces 64 MN / s. on Ether with the latest available drivers. At the same time, the consumption of the card did not exceed 160 watts. During the tests, it warmed up to 53 degrees in a closed test bench at room temperature.
Hashrate RX 6800 XT on other algorithms:
- CuckooCycle: 7.9 G/s # 175W
- KAWPOW: 28.6 MH/s # 175W
- Octopus: 36.5 MH/s # 175W
- ZHash: 88 Sol/s # 175
The parameters for overclocking the RX 6800 XT up to 64 megahashes are below, in the Overclocking section.
Hashrate and Consumption of RX 6900 XT
At the stock settings out of the box, the card outputs 56-59 MH / s, but gradually rises to 61 megahashes, in order to then run into the power limit for the chip and deliver 59 MH / s. At the same time, the consumption of the card according to the readings of the miner reaches 245 watts.
The card consumes 245 watts in drain.
The card will warm up to 90 degrees if the undervolting procedure is not performed. If you make an undervolt, then the temperature of the card can be reduced to 72 degrees with a consumption of 156 watts.
How much does mining on the RX 6900 XT and RX 6800 XT bring?
With proper overclocking, both cards are capable of generating ~ $ 187 per month minus electricity. The price per kilowatt is indicated for the CIS. One card will bring you $ 2,278 per year.
If we scale the farm on the RX 6900 XT or RX 6800 XT to 8 cards, we get $ 48 per month or $ 18 tons per year. Figures are calculated based on the Ether exchange rate of February 22, 2021.
Profit from the farm on 8 XT cards 6900/6800.
