Zen 6 & RDNA 5 Linked to AMD "Medusa" Ryzen Client CPUs

The mysterious Zen 6 "Morpheus" processor architecture was leaked accidentally by an AMD engineer's LinkedIn profile—news outlets picked up on this information last April. Naturally, Team Red's next priority is Zen 5—the latest reports suggest that two different chiplet designs are penciled in for mass production within the second quarter of 2024. Last September, insiders claimed that a proposed EPYC 9006 "Venice" CPU series was based on the sixth-gen microarchitecture. Everest/Olrak_29 has revealed various bits of speculative material regarding futuristic "Ryzen Client" processor designs since the start of 2024.

The latest postings to social media posit that AMD has selected an RDNA 5-based integrated graphics solution (possibly occupying a tile), thus "skipping RDNA 4" on their "Medusa" lineup of Ryzen Client processors. Leaked Microsoft documents revealed that its Xbox hardware design division was considering RDNA 5 for next-gen console specs. Medusa's CPU aspect is allegedly populated by Zen 6 "Morpheus" cores—as claimed in a January tweet. A new package design was also riffed on at the time: "Yes, I have teased this before...Medusa will use 2.5D interconnect with a much higher bandwidth," instead of a "traditional" multi-die design. Industry speculation has AMD's Zen 6 client architecture linked to a loose 2025/2026 launch window.

Leak Suggests Next-Gen Xbox Planned for 2028, AMD Zen 6 & RDNA 5 Considered

A comprehensive leak of documents—from a FTC versus Microsoft case—has exposed short and long-term plans in the world of Xbox. It seems that a relatively mild refresh of current generation Xbox Series X and S is lined up for the second half of 2024, but presentation material (dated April 2022) also reaches far into the future with strategies for next-gen gaming hardware. The bigwigs at Xbox were projecting a "full convergence" of their proprietary "xCloud" gaming platform and physical console hardware to deliver "cloud hybrid games" for 2028—schemes and priorities could have shifted in the interim, given various legal challenges and takeover bids.

One of the slides points to Microsoft getting the technical nitty-gritty sorted by CY2023—with two main options presented for consideration: a licensed ARM 64 design or a "Zen 6-based" AMD 64 processor. The next-gen Xbox's GPU aspect could incorporate a Navi 5 design (RDNA 5)—weighing up either a co-operation with AMD, or an IP license of said graphics architecture. VideoCardz theorizes that: "the latter option seems more likely if the ARM 64 chip is chosen over the Zen 6 APU." A key goal in this area seems to be an implementation of "Next-Gen DirectX Ray tracing" and "ML-based Super Resolutions" features. A Neural Processing Unit (NPU) is marked as a key provision for the 2028 console—granting some nice-to-have perks including: latency compensation, frame rate interpolation and various enrichments of the user experience.
