16-core AMD Ryzen 9 Pro 9965X3D shows up in shipping manifest

AMD appears to be preparing to expand its professional desktop portfolio, bringing its 3D V-Cache technology to the enterprise market for the first time. A new shipping manifest has revealed the Ryzen 9 Pro 9965X3D, a 16-core CPU with a 170W TDP.

The leak, spotted initially by hardware sleuth @Olrak29_ (via VideoCardz), identifies the processor under the product ID 100-000001999. According to the manifest, the chip is a 16-core, 32-thread part with a 170W TDP. This power envelope is particularly notable, as it aligns the Pro model with the Ryzen 9 9950X3D, rather than the more conservative, power-limited SKUs typically found in the series. The “9965” naming convention follows AMD's established pattern of using slightly higher model numbers for its professional-grade chips to distinguish them from their consumer counterparts while maintaining the same underlying Zen 5 architecture.

The database entry marks the processor as being in the Design Validation Testing (DVT) phase. This suggests the silicon is well past the initial Engineering Validation (EVT) stage and is currently undergoing stability and compatibility testing to meet reliability standards. While DVT is a late-stage development milestone, it precedes the final Production Process Validation (PVT), indicating that while a launch is likely, the final release window may still be several months away.

The primary appeal of a Pro X3D chip lies in the intersection of high-capacity L3 cache and business-critical security. While the manifest doesn't explicitly confirm the cache size, we assume it will feature 144 MB of L3, matching the consumer 9950X3D. For professional workloads, this massive cache could provide substantial performance uplifts in latency-sensitive applications. Moreover, the Pro designation confirms the inclusion of the AMD Pro Security stack, including Secure Processor, Shadow Stack, Microsoft Pluton Security, Memory Guard and Platform Secure Boot.

KitGuru says: The existence of a Ryzen 9 Pro 9965X3D suggests that AMD has recognised a growing demand for X3D technology outside of the gaming sphere. For engineers and developers who require the extra cache for specialised software but also need the IT manageability and security of the Pro platform, this chip can offer the best-of-both-worlds.
