AMD Navi 33 And 32 Core Counts For Upcoming Radeon RX 7000 GPUs Leak

Published by


The CU counts for the Radeon 7000 based Navi 32 have leaked kinda. Navi 32 will get a maximum of 3840 shader processors. AMD appears to have revealed the core composition of its upcoming Navi 32 and Navi 33 RDNA 3 GPUs via a ROCm software update on GitHub.

This information came from AMD itself. In a file called "performance.hpp," which was part of an update to the company's ROCm software platform, AMD put out some exciting specifications. Since then, the file has been taken down, but on social media Kepler (@Kepler L2) took a screenshot of a rather important part. The Navi 32 has 60 CUs (made up of 30 WGPs), and the Navi 33 has 32 CUs (16 WGPs). his means that the most shaders a Navi 32-based (RX 7700) graphics card can have is 3840, which isn't a lot to be honest. However, the new architecture can double up on performance thanks to the new architecture. However, this does not guarantee the same level of performance.  

Conversely, on paper, the little Navi 33 GPU appears (RX 7600) to be equivalent to the Radeon RX 6650 XT. When contrasted to RDNA 2's Navi 22 and 23, the last gen GPU has a 50% increase in CU count - 20 extra CUs - while the latter remains the same at 32 CUs.  When put to use, performance should be roughly on par with the Radeon RX 6800. Although it can achieve solid 4K60 performance in many games, we anticipate that Navi 33's small cache and smaller design will make it more challenging to scale to high resolutions.
