Reports suggest that AMD is preparing to expand its Ryzen 9000 "Granite Ridge" lineup with two new Zen 5 CPUs that push the boundaries of power draw and cache capacity. Leaker chi11eddog, known for connections with motherboard vendors, claims that AMD will release an 8-core/16-thread model with a 120 W TDP and a significant 96 MB of L3 cache. This matches the cache density of the current Ryzen 7 9800X3D, but may be a different SKU. More notably, there is talk of a 16-core/32-thread processor with a 200 W power rating and an impressive 192 MB of L3 cache, exceeding the Ryzen 9 9950X3D's 128 MB. The leak suggests that this chip will have a dual-CCD design, with each chiplet combining 32 MB of on-die cache with 64 MB of stacked 3D V-Cache, marking a first for AMD in shipping a desktop CPU with 3D V-Cache on both dies.
If these rumors are true, AMD may have found a solution to the economic challenges of dual-X3D production. Previously, the company's top 16-core models paired a single 3D V-Cache chiplet with a standard CCD. The new dual-stacked design eliminates this compromise and offers consistently high cache bandwidth for multithreaded workloads. If released, these CPUs would strengthen AMD's position in gaming performance and introduce true dual-X3D dies to the mainstream desktop market.
