What's more interesting is the rumor that the current "Zen 5" will remain AMD's mainstay for the entirety of 2025, and possibly even most of 2026, at least for the desktop platform. AMD will be banking heavily on the recently announced Ryzen 7 9800X3D, and its high core-count siblings, the Ryzen 9 9950X3D and possible 9900X3D, to see the company through for 2025 against Intel. The 9800X3D posted significantly higher gaming performance than Intel, and the 9950X3D is expected to be at least faster than the 7950X3D at gaming, which means its gaming performance, coupled with multithreaded application performance from its 16-core/32-thread count should be the face of AMD's desktop processor lineup for at least the next year.
It wouldn't be off-character for AMD to launch "Zen 6" on AM5, and not refresh the platform. The company had launched three microarchitectures (Zen thru Zen 3) on Socket AM4. With "Zen 6," AMD has the opportunity to not just increase IPC, but also core-counts per CCD, cache sizes, a new foundry node such as 3 nm, and probably even introduce features such as hybrid architecture and an NPU to the desktop platform, which means it could at least update the current 6 nm client I/O die (cIOD) while retaining AM5. A new cIOD could give AMD the much-needed opportunity to update the DDR5 memory controllers to support higher memory frequencies. The Kepler_L2 leak predicts a "late-2026 or early-2027" launch for desktop "Zen 6" processors. In the meantime, Intel is expected to ramp "Arrow Lake-S" on Socket LGA1851, and debut the "Panther Lake" microarchitecture on LGA1851 in 2025-26.
Keeping the same socket should help reduce costs in my personal opinion.
