AMD gaming CPUs like the 9950X3D only have one 3D V-Cache because the performance gain isn't worth the cost, according to the company.

AMD unveiled two new Ryzen 9 9000-series processors at CES 2025 with frame-rate-boosting 3D V-Cache as its latest top-end desktop chips for gamers and creators.

AMD also announced slightly slower 9900X3D chip with 12 cores, a 5.5GHz max boost speed and 140MB of cache. Consider it the slightly more sensible alternative to the 9950X3D's extravagant cache. Both chips will be available in the first quarter.
