You can expect AMD to announce the Radeon RX 6700 XT on March 3 with a starting price between 479 and 499 dollars for the reference models.
Expect AIB cards to get more expensive though, in the 500 USD range. YT channel Moore's Law is Dead claims that there will be larger availability of the Radeon RX 6700 XT. However, where the channels is basing that on, is unknown. You also need to weigh in the current state of the cryptocurrency mining business. Radeon RX 6700 XT would be based on a NAVI 22 XT GPU, very likely 40 CUs/2560 SP. The memory should total 12 GB at 192 bits.
The base model is thought to outperform GeForce RTX 2080 Super, and would be roughly comparable to the RTX 3060 Ti which costs $399 (well, at least it should cost that). The OC variant of the 6700 XT would offer higher clock speeds and performance closing in on the RTX 3070 range, that card would however get a higher 230W TGP. AMD will formally present the card at 5:00 PM Western European Time upcoming Wednesday.
