AMD says top-tier Ryzen 9900X3D and 9950X3D CPUs arrive March 12 for $599 and $699
Briefly

AMD's latest 9000-series X3D chips utilize a dual-chiplet design similar to the 7950X3D and 7900X3D, which integrates one chiplet with an additional 64MB cache and another without. This setup allows AMD's software to efficiently manage CPU core usage, directing non-gaming tasks to cores with higher clock speeds while gaming tasks leverage the cache-enhanced cores. Previous tests confirmed the effectiveness of core parking technology, and AMD recommends a clean Windows install and updated drivers to ensure seamless performance. These measures enhance compatibility and optimize the use of these advanced CPUs for gaming.
Like the 7950X3D and 7900X3D, the new X3D chips combine AMD's CPU chiplets with enhanced cache, optimizing performance for gaming and non-gaming workloads.
AMD's software intelligently allocates tasks to the chiplet cores based on workload type, ensuring optimal performance by utilizing non-gaming workloads on normal cores and gaming tasks on cache-enhanced cores.
