AMD’s Navi31 GPU Pictured, Design In Line With Previous Leaks
AMD will showcase their RDNA3 GPUs in less than 12 hours. This time around, team red has not let that many leaks slip out. However, Angstronomics just posted an article showcasing a die shot of AMD’s Navi31 GPU. To recap, Navi31 is the flagship GPU from AMD’s RDNA3 lineup expected to be used on the RX 7900 XTX and the RX 7900 XT.

RDNA3, What Do We Know So Far
The RDNA3 microarchitecture offers a major leap in performance along with increased efficiency across the board. RDNA3 features the next generation of Infinity Cache, a modified Graphics Pipeline along with a re-architectured Compute Unit. All such improvements generation on generation are tipped to offer a massive leap not just in raw vectorized performance, but also in ray tracing workloads.
