AMD Ryzen “Zen 6” Processors and Radeon “UDNA” Graphics Cards to Feature N3E Technology, Anticipating High-End Gaming GPUs and Advanced 3D Stacking for Next-Gen Halo and Console APUs

Speculations surrounding AMD’s upcoming Ryzen “Zen 6″CPUs and Radeon “UDNA”GPUs have recently surfaced, accompanied by updates on next-gen 3D stacking technologies.

AMD’s Future: Insights into Ryzen “Zen 6″and Radeon “UDNA”Technology

A member of the Chiphell Forum, Zhanzhonghao, has shared intriguing rumors hinting at AMD’s plans for future semiconductor architectures. While the information must be taken as unconfirmed, it provides a compelling glimpse into what AMD might achieve in the near future.

Initial details suggest that AMD’s next-generation Ryzen CPUs, referred to by the codename Medusa Ridge, will incorporate the Zen 6 CCD architecture using the advanced N3E process technology. An enhanced I/O die featuring the N4C process node will also be part of these new CPUs, ensuring improved I/O and integrated GPU functionalities compared to the existing architecture.

Earlier insights indicate that the Medusa series will maintain compatibility with the AM5 socket and could feature a core count of up to 32 cores. This marks a significant increase, effectively doubling the core count seen in previous Zen 4 CCDs. The anticipated launch date for these CPUs is expected between late 2026 and early 2027.

On the graphics side, AMD is poised to introduce the next-generation UDNA lineup, which aims to replace the current RDNA and CDNA architectures. Built on TSMC’s N3E process technology, this unified architecture is rumored to provide significant advancements, particularly in gaming. The UDNA series will herald the return of enthusiast-grade Radeon products, succeeding the RDNA 4 “Radeon RX 9000″lineup targeted at mainstream users. Mass production of these GPUs is set to commence in Q2 2026, featuring an all-new architectural design that may also integrate into the forthcoming PlayStation 6 console.

In addition to Ryzen and Radeon advancements, AMD is also expected to refine its 3D stacking solutions. These updates will be applied to future Halo APU families, with Sony potentially incorporating similar 3D stacking technology in its next-gen consoles. It remains to be seen whether this innovation will involve various Core IP stacks, the 3D V-Cache technology, or a combination of both.

AMD has a promising lineup scheduled for release over the next year, particularly in mobility, leading up to a significant transition to the new Zen 6 and UDNA architectures that promise to redefine performance standards in the PC market.
