3DCenter.org has shared a rumor suggesting that AMD’s Radeon RX 6000 Series successors could feature a multi-chip-module (MCM) design, which is similar to what NVIDIA is reportedly planning for its “Hopper” family of next-generation graphics cards. The speculation stems from Kepler_L2, who claims that red team has had a working version of Navi 31 since early 2020. He also revealed that the top SKU, which may very well turn out to be the Radeon RX 7900 XT, boasts a pair of 80 CU chiplets for a potential total of 10,240 Stream Processors—5,120 more than the current Radeon RX 6900 XT flagship.
“Navi31 working silicon exists since early 2020,” Kepler_L2 tweeted. “Nothing I can confirm 100% now, but from what I know Navi 31 is a 80 CU chiplet and top SKU has 2 of them.”

Another enthusiast has shared patents that provide additional insight into what AMD might be planning for its next-generation Radeon GPUs. One patent that relates to synchronizing workloads seems to confirm that red team is making headway on developing MCM-based GPUs, while a second suggests that upcoming Radeon cards could feature considerable performance improvements in the ray-tracing department.
“Described herein are techniques for performing ray tracing operations,” an abstract reads, hinting at new ray tracing techniques that may debut as part of AMD’s upcoming RDNA 3 graphics architecture. “A command processor executes custom instructions for orchestrating a ray tracing pipeline. The custom instructions cause the command processor to perform a series of loop iterations, each at a particular recursion depth.”
