AMD Navi 33 to get 80 CUs with 5120 cores?

The current video card lineup isn't complete yet but rumors about next-gen parts are already circulating. Today there's fresh news about the Navi 33, an upcoming model based on AMD's RDNA3 architecture. The Navi x3 is not a high-end offering, but the specifications hint at a very big performance uplift.

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.

Navi 33 (?) = Navi 21 + Next Gen IP Core
