AMD appears to be working on a new Ryzen PRO desktop CPU that could bring 16 cores and 3D V Cache to its business focused lineup for the first time. The chip, listed as Ryzen 9 PRO 9965X3D, has appeared in a PassMark entry, though the details should still be treated as early and unconfirmed.
Ryzen PRO chips are made for professional systems, office fleets, creators, and managed business PCs. They usually focus on security, stability, manageability, and long term support. Until now, AMD’s Ryzen PRO desktop range has generally topped out at 12 cores. This leak suggests AMD may be preparing a much stronger PRO option.
Ryzen PRO could finally get a high end X3D model
The Ryzen 9 PRO 9965X3D is expected to use AMD’s Zen 5 architecture with 16 cores and 32 threads. The listing suggests it may have a cache layout similar to the Ryzen 9 9950X3D, though PassMark appears to show an incorrect L3 cache figure. The report notes that the benchmark may not be reading the 3D V Cache properly.
The leaked CPU is slower than the Ryzen 9 9950X3D in PassMark, but not by much. It is listed around 7.3% behind in multi threaded performance and around 2.7% behind in single threaded performance. That gap would make sense if the PRO chip runs at a lower power limit.
| CPU | Cores and threads | Cache | Expected focus |
|---|---|---|---|
| Ryzen 9 PRO 9965X3D | 16 cores and 32 threads | Expected 3D V Cache | Professional systems with strong gaming and creator performance |
| Ryzen 9 9950X3D | 16 cores and 32 threads | 128MB L3 plus 16MB L2 | High end gaming and desktop performance |
| Ryzen 9 PRO 9945 | 12 cores and 24 threads | 64MB L3 plus 12MB L2 | Business and workstation desktops |
The biggest unknown is power. Ryzen PRO chips often run at 65W, but an earlier leak reportedly listed this model at 170W. That makes a big difference. A 65W version would be very efficient and attractive for compact workstations or managed business PCs. A 170W version would be closer to a standard high performance desktop chip with PRO features.
If AMD really ships this CPU with a lower TDP, it could be useful beyond business desktops. Many gamers and creators already undervolt high end Ryzen chips for better efficiency. A 16 core X3D PRO chip with strong out of the box efficiency could appeal to people who want high performance without manual tuning.
The chip would also give AMD a clearer workstation option for people who want both business class features and 3D V Cache. That cache is especially valuable in games, but it can also help some professional workloads that benefit from keeping more data close to the CPU.
For now, this is still a leak. AMD has not confirmed the Ryzen 9 PRO 9965X3D, and PassMark listings can sometimes be incomplete or inaccurate. Still, the idea makes sense. AMD already has strong X3D desktop chips, and bringing that technology into the Ryzen PRO stack would give business PCs a more powerful option.
If the leak is accurate, this could become AMD’s most interesting Ryzen PRO desktop chip yet. The final value will depend on clock speeds, TDP, pricing, and whether AMD makes it easy to buy outside OEM systems.
