  • AMD has offered 'X3D' variants of high-end desktop processors for about four years, featuring an extra 64MB of L3 cache (3D V-Cache) that benefits games.
  • Ryzen 5000 and 7000 series stack the cache on top of the CPU die, while Ryzen 9000 places it beneath.
  • 12- and 16-core Ryzen chips (e.g., 7900X3D, 7950X3D, 9900X3D, 9950X3D) split CPU cores between two chiplets, with only one having 3D V-Cache, leading to occasional software management issues.
  • The new Ryzen 9 9950X3D2 Dual Edition includes 64MB of 3D V-Cache on both dies, eliminating the hybrid arrangement.
  • Total cache for the 9950X3D2 is 208MB (16MB L2, 64MB L3, and 128MB 3D V-Cache), offering up to 10% better performance in cache-sensitive tasks compared to the 9950X3D.
