AMD is expected to introduce two more Navi 22 'RDNA 2' graphics cards after the Radeon RX 6700 XT, the RX 6700, and RX 6600 XT. We have got a few hints of what the specifications of these cards might look like but when it comes to memory configuration, it looks like AMD may now be deciding to feature 12 GB GDDR6 VRAM across all three of its mainstream offerings.

When the specifications first leaked out, it was reported that the AMD Radeon RX 6700 (Non-XT) variant would feature 6 GB GDDR6 VRAM which is half the amount featured on the RX 6700 XT. There's also the Radeon RX 6600 XT which was leaked a while back and is suggested to feature a higher memory capacity than the RX 6700 of 12 GB. Just like NVIDIA, this confusing GPU memory configuration (RTX 3060 12 GB vs RTX 3060 Ti 8 GB) doesn't make sense at all but based on a very recent listing at EEC, it looks like AMD has changed its plan.
