AMD Navi 31 rumored to feature dual 80 CU design

Fresh rumors are spreading about AMD's next-generation GPU architecture. The future Navi 31 is believed to be AMD's first multi-chip module (MCM) GPU. According to the rumor mill, Navi 31 is a chiplet with 80 CUs. The top model will reportedly have two chiplets, resulting in a total of 160 CUs, double as much as Navi 21. This suggests a total core count of up to 10240 cores.

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. We are still waiting for more details on AMD’s implementation of Deep Learning Super Sampling for AI-based super-resolution technology. Those, however, would be based on Tensor-like compute cores and AMD has so far not implemented such cores into their GPUs. Would Navi 31 offer such a type of core? It is unknown yet.

Twitter user @Underfox3 recently discovered AMD filed patents that talk about a technique to synchronize workloads between MCM-based GPUs and also a new command processor orchestrating ray tracing pipeline.

Patent: Command processor based multi dispatch scheduler - AMD

Command processor to orchestrating the ray tracing pipeline, accelerating ray tracing execution.

The 2nd gen AMD Ray Tracing is coming.

AMD's RDNA3 architecture is expected later this year or in 2022.
