AMD officially confirms Zen 6 “Medusa” Ryzen CPUs at OCP 2025 AMD confirms the leaked codename for Zen 6 Ryzen CPUs—Are all the leaks true? At the Open Compute Project Global Summit, AMD confirmed the codename for its next-generation Zen 6 Ryzen CPUs.
AMD’s Zen 6 Ryzen CPUs are “Medusa”, a name that has long been discussed by hardware enthusiasts thanks to prior leaks. This seemingly confirms some of the leaks about AMD’s next-generation Ryzen desktop CPUs.
Below, AMD has confirmed that it plans to release openSIL-based firmware for its next-generation Ryzen CPUs in early 2027. This firmware will replace AMD’s proprietary AGESA firmware.
This move aims to deliver improved transparency, security, and customisation for its future Ryzen processors. AMD’s 6th Generation Zen 6 EPYC “Venice” CPUs will be the first to ship with openSIL firmware. These EPYC CPUs will launch in 2026.
What do we know about AMD’s Zen 6 Ryzen “Medusa” CPUs: AMD plans to release Zen 6 Ryzen CPUs in 2026. Based on prior “Medusa” leaks, these CPUs will feature up to 24 CPU cores with two 12-core CCX/CCD chiplets. This increases the maximum core count per chiplet from 8 to 12. Furthermore, it increases the L3 cache per CCX/CCD from 32 MB to 48 MB.
If these leaks are true, AMD’s Zen 6 CPUs should deliver much higher gaming performance than their Zen 5 counterparts. Gaming is very cache sensitive, so having more L3 cache on a Zen 6 CCD will boost gaming performance. Add on other Zen 6 architectural enhancements, and AMD’s next-gen Ryzen CPUs should be strong performers.
Another leak claims that AMD is targeting 7 GHz clock speeds with its Zen 7 CPUs. If this is true, AMD should deliver significant gains in single-threaded CPU performance. This will accelerate all workloads, though highly single-threaded workloads will see the largest impact.
If this leak is true, AMD’s Zen 6 CPUs will benefit from higher core counts, more per-CCD cache, and higher clock speeds. That would be a huge win for AMD. You can join the discussion on AMD’s confirmation of Zen 6 “Medusa” Ryzen CPUs on the OC3D Forums.
