RX 6800 VS RX 6900 XT Mining: Hashrate | Profitability | Best Settings | KAWPOW

RX 6800 VS RX 6900 XT Mining: Hashrate | Profitability | Best Settings | KAWPOW – AMD launched the RX 6000 series of cards to compete with the NVIDIA RTX 3000 series on price and performance. Let’s see what they did and if these cards can be used for mining.

Specifications RX 6900 XT and RX 6800 XT

Since the RX 6900 XT is an “improved” version of the RX 6800 XT, we will be looking at them together.

In the rating of the resource TechnicalCity these video cards … Both cards received a chip based on a full-fledged RDNA 2 architecture, codenamed NAVI 21.

6800 XT and 6900 XT Specifications

The cards received 16 GB of GDDR6 video memory [SDRAM] for reference and reference models. The memory speed is 2250 MHz on a 256-bit bus, which gives a total bandwidth of 512 GB / s. To power the card, double unpaired 8-pin connectors are used. The approximate noise level produced by the cards was 44 dB.

By design, the cards differ minimally, they even have… But the models have a different number of cores and texturing units. So, in 6900 XT , while the 6800 XT … In fact, this is the main difference between one graphics accelerator and another.

Reference card models weigh 1.5 kg each. – mainly due to the cooling system. The standard card is equipped with 3 90mm coolers. So for their installation in the rig, it is recommended to strengthen the structure, because the total weight of 8 cards will be 12 kg.

Older RX 6900 XT in some moments even RX 3090, but in some it is quiet green camp. In general, if you are not planning , then red cards can be a good analogue for green… Subject to any price advantage towards the RX-6xxx XT.

Mining on Radeon RX 6900 XT and RX 6800 XT: benchmarks, hashrate, consumption

The first tests showed that the 6800 XT shows 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 are no mining differences 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
  • Disk: 1TB Samsung Pro980 NVME Gen4
Hashrate and Consumption of RX 6800 XT

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 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.

Hashrate and Consumption of RX 6900 XT

The card consumes 245 watts in drain.

The card will warm up to 90 degrees if the undervolting procedure is not carried out. 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 for LPG. One card will bring you $ 2,278 per year.

How much does mining on the RX 6900 XT and RX 6800 XT bring?

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.

Comparison of cards from Nvidia in mining against 6900 and 6800 shows that the advantage is still on the side green.

Overclocking 6900 XT and 6800 XT for Ethereum mining

Overclocking through Radeon Software following the example of reviewers and miners. Before starting overclocking, disable MSI Afterburner and do not enable it 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

  • 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.
