Here are some rumors about AMD’s next generation GPU Navi 31, also known as RDNA 3. According to Twitter user @Kepler_L2, it is rumored that Navi 31 has a dual chiplet design with 80 Compute Units each. This means that the GPU could offer up to 160 CUs in total, twice as many as Navi 21.
AMD RDNA 3 is also expected to bring a noticeable performance upgrade in ray tracing. Based on reviews, the RDNA 2 implementation of ray tracing hardware acceleration is clearly not as good as NVIDIA 2nd Gen RT core, so AMD has a lot of work to catch up.
AMD Navi 31 is expected to be announced in late 2021 to early 2022, to compete with NVIDIA’s AD102.
