AMD says it is expanding its Ryzen PRO 9000 desktop workstation lineup with higher-power configurations and models featuring 3D V-Cache. The reported six-model expansion includes the Ryzen 9 PRO 9965X3D, which AMD lists with 16 Zen 5 cores, 32 threads, 128MB of L3 cache and a 170W default thermal design power, or TDP.
AMD says systems featuring the additions are expected in the second half of 2026. The company expects Lenovo’s ThinkStation P4 workstation to become available in the third quarter of 2026.
Six reported additions
AMD lists two 16-core models: the Ryzen 9 PRO 9965X3D and Ryzen 9 PRO 9965. Both have maximum boost clocks of up to 5.5GHz and a 170W default TDP. The non-X3D processor has 64MB of L3 cache, half the X3D model’s capacity.
The company also lists the 12-core, 24-thread Ryzen 9 PRO 9955 and eight-core, 16-thread Ryzen 7 PRO 9755. Both have a 120W default TDP and maximum boost clocks of up to 5.4GHz.
Two further additions, the Ryzen 7 PRO 9755X3D and Ryzen 5 PRO 9655, are reported to bring eight-core X3D and six-core configurations to the 120W tier. Their reported specifications appear alongside AMD’s listed configurations below.
| Processor | Cores / threads | Maximum boost clock | L3 cache | Default TDP |
|---|---|---|---|---|
| Ryzen 9 PRO 9965X3D | 16 / 32 | Up to 5.5GHz | 128MB | 170W |
| Ryzen 9 PRO 9965 | 16 / 32 | Up to 5.5GHz | 64MB | 170W |
| Ryzen 9 PRO 9955 | 12 / 24 | Up to 5.4GHz | 64MB | 120W |
| Ryzen 7 PRO 9755X3D — reported | 8 / 16 | Up to 5.2GHz | 96MB | 120W |
| Ryzen 7 PRO 9755 | 8 / 16 | Up to 5.4GHz | 32MB | 120W |
| Ryzen 5 PRO 9655 — reported | 6 / 12 | Up to 5.4GHz | 32MB | 120W |
The reported Ryzen 7 PRO 9755X3D configuration has 96MB of L3 cache, compared with the 32MB AMD lists for the Ryzen 7 PRO 9755. Its reported maximum boost clock is lower, at up to 5.2GHz rather than 5.4GHz.
AMD says the additional cache is intended to improve performance in data-intensive workloads such as simulation, rendering and real-time visualization.
AM5 platform and commercial features
The expansion adds 120W and 170W options above the existing 65W Ryzen PRO 9000 models. These remain AM5 desktop processors for commercial systems, rather than Threadripper PRO workstation processors.
AMD describes the PRO platform as providing security, manageability and platform stability for business deployments. Its product listings include DASH manageability support, AMD Memory Guard, AMD Secure Processor and AMD Platform Secure Boot.
AMD notes that some technologies require third-party enablement or activation. Supported features can vary by operating system, and specific capabilities depend on the system manufacturer.
