AMD’s Ryzen 9 9950X3D2 Dual Edition crams 208MB of cache into a single chip

AMD is releasing the Ryzen 9 9950X3D2 Dual Edition, a new processor that places 64MB of 3D V-Cache on both of its two CPU chiplets rather than just one. This results in a total of 208MB of cache (16MB L2 + 64MB L3 + 128MB 3D V-Cache). The change eliminates the asymmetric cache arrangement that has caused occasional scheduling issues in previous 12- and 16-core X3D chips, where driver software had to route cache-sensitive workloads to the correct chiplet. AMD claims up to 10% performance improvement over the 9950X3D in games and cache-sensitive applications.
