AMD X970E motherboards could use a refreshed PROM21 chipset
AMD’s next-generation Ryzen motherboards could be very similar to today’s designs
This week, Biostar confirmed that it plans to showcase “next-generation AMD” motherboards at Computex 2026. While the company did not release any information about these motherboards, it did unveil that we would learn more very soon. According to the leaker MEGAsizeGPU, the next generation of AMD motherboards could feature a refreshed PROM 21 chipset design, but with some “fundamental changes”.
AMD’s high-end 600-series and 800-series motherboards utilise PROM 21 chipsets. If this leaker is correct, the same could be true for AMD’s next-generation AM5 motherboards. While this would limit the advancements that AMD could deliver with its next-generation motherboards, it would enable lower motherboard costs. After all, AMD’s PROM 21 chipset is a mature chip design.
While the chipset itself is reportedly identical to AMD’s prior AM5 motherboards, there’s more to a motherboard than its chipset. AMD’s new motherboards will reportedly support CUDIMM or CAMM2 memory modules. CUDIMM memory modules feature built-in clock drivers that boost signal integrity and enable higher memory speeds. This could allow future (Zen 6) AMD Ryzen CPUs to support much faster memory speeds.
It could be another PROM 21 refresh, but with full CUDIMM/CAMM support. Chipset-wise, it's the same as 600/800, but the BIOS and RAM support have undergone fundamental changes. https://t.co/uD7PA0p3aA

For AMD’s next-generation motherboards, chipset-level features may not change. That said, other areas of AMD’s AM5 motherboard designs may see fundamental changes. It looks like AMD has tuned its next-generation motherboard designs to support faster memory modules and new memory options. There may also be some new BIOS options that will be unavailable on older AMD motherboard designs.
You can join the discussion on AMD’s next-generation motherboard chipset on the OC3D Forums.
