Coming to the VRAM configurations, it is said that Navi 21 will feature 16 GB VRAM. From previous leaks, we have seen an alleged engineering sample with the "Big Navi" GPU that featured 16 GB of Samsung's GDDR6 memory across a 256-bit wide bus interface. In addition to that, the Navi 21 chip is likely to be housed by the Radeon RX 6900 XT GPU.

The second variant, the Navi 22 GPU, is said to feature 12 GB of VRAM and that would most likely be featured across a 192-bit bus interface. Based on the specifications, the Navi 22 GPU could be used in cards that would be the successor to the Radeon RX 5700 XT series. We can't say for sure what AMD will call them but they could either be branded as the Radeon RX 6700 XT or Radeon RX 6800 XT series cards.

Rogame also mentions that it is currently unknown if the two variants he has confirmed are based on the full (Navi 21/22) GPU dies or a cut-down variant. The lower bus interface on flagship cards is slightly weird but there's a possibility that these are just early engineering boards. Do note that 16 GB and 12 GB VRAM are also possible with 512-bit and 384-bit bus interface so AMD is also open to that option when the final specifications are released.

AMD Radeon RX 6900 Series With Triple-Slot Cooling Solution: As for the designs themselves, the Radeon RX 6000 flagship cooling design looks amazing with the red and black design. The card features a triple axial-tech fan setup on the shroud and has a large aluminum heatsink that runs beneath it. The card has a LED-lit Radeon logo on the side and there is a large cut out on the side for the fans to vent out hot air. This design is very reminiscent of the NVIDIA GeForce RTX 20 series Founders Edition cooler. The card will feature dual 8-pin power and display ports would include a USB Type-C (VirtualLink), 1 HDMI, and 2 DisplayPort connectors.
