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.
