It's been rumored for a long time now that Big Navi will feature up-to 80 CUs and as such 5120 Stream Processors. But as we get closer to the announcements, more and more rumors seem to solidify.
Word on the street right now is that AMD has provided its board partners with more details, final names, and more. The chaps from Videocardz claim to have cross-checked parts of the specs, and are confident that these are more or less final.
"Navi 21" and "Navi 22" are 7nm parts that will lead the high-end to the enthusiast-class lineup. The flagship part is the Radeon RX 6900 XT, followed by the RX 6800 XT and RX 6800; which are all based on the "Navi 21." and get 16GB of GDDR6 graphics memory. These are accompanied by the RX 6700 XT and RX 6700, which are based on the "Navi 22" silicon. All charted up that looks like this:
