AMD Confirms Max Compute Units for RDNA 3.0 GPUs

A new update directly from AMD to the ROCm software confirms Navi 32 and Navi 33 max core counts.

Back in August, a rumor from Angstronomics alleged that the specifications of the AMD Navi 3X GPU series did not change since 2020. The website also alleged the final specifications of each of AMD’s Navi 3X GPUs, including max core counts, code names, and infinity cache sizes to name a few.

It seems that Angstronomics alleged specs were indeed correct, at least regarding the peak core counts, as a new leak coming directly from AMD after an update to the ROCm software discovered by Twitter user Kepler confirmed the peak computing core counts for the RDNA 3.0 architecture based GPU series.

RDNA is AMD’s GPU microarchitecture featured for the first time on the Radeon RX 5000 series that launched back in 2019, whereas Navi is the codename for the GPU series utilizing the RDNA architecture, and once again the Navi GPUs have been exclusively used in the RX 5000 series, expanded to the RX 6000 series in 2020, and will power AMD’s upcoming RX 7000 series launching in December.

Core Counts For RDNA 3.0 Based GPUs

The RX 7000 series will consist of the Navi 31 GPU powering AMD’s upcoming flagship graphic cards the Radeon RX 7900 XT and Radeon RX 7900 XTX, Navi 32 will power the Radeon RX 7800 XT, whereas the Navi 33 GPU will be featured in the Radeon RX 7700 XT.
