AMD reportedly tapes out Zen 6 Desktop silicon for potential Q4 launch
AMD could target a Q4 2026 launch for Zen 6 desktop with X3D SKUs
AMD has reportedly taped out its Zen 6 desktop silicon, a new “B0” stepping that reportedly targets high frequencies to enable higher levels of desktop performance. Based on a report from Moore’s Law is Dead, this new “Zen 6 Powderhorn” stepping should be AMD’s final stepping, which means that this is AMD’;s launch-ready silicon.
This chip will reportedly be used for AMD’s Zen 6 desktop CPUs and their planned X3D variants. If all goes to plan, AMD could target a Q4 2026 launch. However, a Q1 2027 launch seems like a safer bet. Depending on Intel’s actions and Nova Lake’s performance, AMD could launch Zen 6 with X3D CPU variants alongside non-X3D models. However, AMD is most likely to follow its standard Zen release schedule, with non-X3D chips launching before their 3D V-Cache-enhanced counterparts.

AMD’s Zen 6 processors, if the rumours are correct, will represent a major leap for AMD. AMD’s Zen 6 desktop CPUs will reportedly use CCDs with up to 12 cores and 48MB of L3 cache. That’s a 50% increase in core count and cache. These CPUs will also reportedly feature higher core clock speeds and be compatible with today’s AM5 motherboards. Those are some huge gains for AMD, especially when combined with other architectural enhancements.
AMD’s Zen 6 CPUs will reportedly max out at 24 cores across two 12-core CCDs. AMD has also reportedly reworked its chiplet designs to deliver a “latency revolution“, which could further enhance performance. All in all, Zen 6 is expected to be an exciting launch for AMD.
At present, it is unknown if AMD will discuss desktop Zen 6 at Computex 2026. AMD’s earliest Zen 6 processors will likely be datacenter-grade EPYC CPUs. AMD confirmed this month that it was ramping up production of its Zen 6 “Venice” CPUs.
