AMD RDNA 5 GPUs Are Rumored to Be Built on a Large Scale Architecture Change
Rumors making rounds suggest that the company will change the cores' architectures under AMD's next generation of graphics architecture, which is the RDNA 5 "Radeon." As for the report on Chiphell forums, it is assumed that RDNA 5 GPUs could boast a maximum of 128 cores for compute unit (CU) space, doubling the current entry-level numbers from the current 64 cores per CU found in the RDNA 4 architecture.
Potential Configurations for RDNA 5 Cores
It has been previously indicated that AMD will offer four die configurations for RDNA 5 GPUs. If the assumptions about 128 cores per CU are indeed held true, then the core counts for the die would be high:
- Top Tier Die (96 CUs): 12,288 Cores
- Mid Tier Die (40 CUs): 5,120 Cores
- Low End Die (24 CUs): 3,072 Cores
- Entry Level Die (12 CUs): 1,536 Cores
Assets, therefore, represent an increase of 3x over the most high-end RDNA 4 GPU (Navi 48) and 2x over the last AMD flagship, the Navi 31 (RDNA 3).
Return to a Full-Range GPU Portfolio
It is very much similar to the four-die rumors for RDNA 5: RDNA 2 were also four distinct dies, and all were very competitive in the ultra-enthusiast segment with marvelous products like the RX 6900 XT.
And this is different from the RDNA 4 generation, which only features two dies (Navi 48 and Navi 44) in a cheaper monolithic design. While this resulted in a better supply chain compared to the chiplet-based RDNA 3, the setup immediately positioned AMD's offerings against the NVIDIA 80-series cards, instead of against its top-tier enthusiasts.
The Implications for High-End Gaming
The greater potential core count, alongside the wider product stack, suggests that AMD is gearing up for a return to the ultra-enthusiast GPU market for RDNA 5. Expected improvements in comparison with earlier generations include rigorous enhancements in ray tracing (RT) and AI performance.
If these rumors hold true, the RDNA 5 architecture could allow AMD to close the performance gap with its competitors, as well as once again entice PC gamers at the very highest end of the market with a flagship product.
