Ethereum mining RX 6800 and RX 6900 XT specs: hashrate, profitability and performance
AMD launched the RX 6000 series of cards to compete with the NVIDIA RTX 3000 series in terms of 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 resource TechnicalCity these video cards [ got to the second and third places ]. 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 [ SDRAM ] video memory 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 [the number of transistors is the same ]. But the models have a different number of cores and texturing units. So, 6900 XT [ 5120 cores and 320 Texture units ], while 6800 XT [ 4608 cores and 288 Texture units ]. In fact, this is the main difference between one graphics accelerator from 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.

RX 6900 XT and RX 6800 XT Gaming Performance
In games, the RX 6800 XT can outperform [ RTX3090 in Dirt 5 at 1440p and 4K, as well as in Death Stranding at 1440p ], but only by a couple of frames. At the same time, the AMD card lags behind. Full review of RX 6800 gaming performance.
The older RX 6900 XT in some moments [ tears ] even the RX 3090, but in some it quietly [ merges ] the green camp. In general, if you do not plan to [ render 60 FPS video using neural networks ], then red cards can be a good analogue for green ones . Subject to any price advantage towards the RX-6xxx XT.
