80 CUs and 5120 cores?Citing a tweet from reliable leaker KittyYuko, WCCF Tech reports Navi 33 will get the same core configuration as the Navi 21. This likely means 80 CUs and a total of 5120 cores, but based on a next-gen IP core.
There is also a rumor about a flagship Navi 31 with a MCM (multi-chip module) design featuring Navi 33 chips. This implies we could see a model with 160 CUs and a total of 10,240 stream processors:
AMD Navi 31 chips will end up with an MCM solution and feature dual 80 Compute Unit chiplet dies, and each would feature 5120 cores. This would round up to a maximum of 160 Compute Units & a total of 10,240 stream processors. If that ends up being the case (& it's looking more so than ever that it would be), then we can definitely expect an 80 CU Navi 33 part. The Navi 32 SKU could end up with around 120-140 CUs and that too could be a multi-chip-module design.We'll have to wait and see if it's true. The rumored launch date is Q2 2022 or Q3 2022, so it's not like these chips are coming anytime soon.
