AMD is reportedly gearing up to expand its Ryzen 9000 "Granite Ridge" lineup with two all-new Zen 5 CPUs that push the limits of power draw and cache capacity. Leaker chi11eddog, who has cultivated ties with motherboard vendors, claims that AMD will introduce an 8-core/16-thread model rated at 120 W TDP, featuring a substantial 96 MB of L3 cache. This mirrors the cache density of the existing Ryzen 7 9800X3D, but could represent a distinct SKU. More striking is the rumored 16-core/32-thread part, a 200 W processor boasting 192 MB of L3 cache, surpassing the Ryzen 9 9950X3D's 128 MB. According to the leak, this chip features a dual-CCD design, with each chiplet pairing 32 MB of on-die cache with 64 MB of stacked 3D V-Cache, marking the first time AMD may ship a desktop CPU with 3D V-Cache on both dies.

If these claims prove accurate, AMD may finally have solved the economic puzzle of dual-X3D production. Until now, the company's top-end 16-core models have paired a single 3D V-Cache chiplet with a standard CCD. The new dual-stacked design removes that compromise and promises consistently high cache bandwidth across multithreaded workloads. If launched, these chips would reinforce AMD's gaming performance crown and finally bring true dual-X3D dies to the mainstream desktop arena.
