The Navi 22 GPU is currently expected to debut as Navi 12 successor. This is a dedicated GPU for Apple Mac. A predecessor, Navi 12 was released just a few weeks ago. This is a custom Navi 10 variant featuring HBM2 memory. It seems reasonable to expect Navi 22 to also feature HBM2. Since Navi 12 had the same number of cores as Navi 10, the 22 could also be considered a custom variant of the Navi 21 (Big Navi). However, for now it is all just speculation.Previously, we already heard about "Sienna Cichlid". That's the codename of Navi 21, the "Big Navi" chip.
