AMD 100-100000725WOF Ryzen Threadripper PRO 9955WX 16-Core Workstation Processor

Overview

The AMD 100-100000725WOF is a Ryzen Threadripper PRO 9955WX processor from the 9000 series — a 16-core, 32-thread workstation CPU built on AMD's 4nm process and paired with the sTR5 socket platform. It's positioned for engineers and integrators speccing single-socket workstations that need server-class core counts and memory bandwidth without moving to a dual-socket EPYC platform. For surveillance and video-wall integrators building recording servers, analytics workstations, or multi-stream transcoding rigs, the 9955WX gives you a high core count and a 4.50 GHz base clock in one socket, which matters when a single box has to run VMS software, run AI-based video analytics, and handle simultaneous multi-channel decode without contention. The 100-100000725WOF (often searched as 100 100000725WOF) ships as a boxed processor for system builders and integrators assembling or upgrading Threadripper PRO workstations.

Key Features

• 16 Cores / 32 Threads: A hexadeca-core design with full simultaneous multithreading gives you 32 logical threads for parallel workloads — video transcoding, multi-camera analytics pipelines, or simulation jobs that scale linearly with thread count won't bottleneck on core availability the way an 8-core desktop chip would.
• 4.50 GHz Base / 5.40 GHz Boost: A 4.50 GHz all-core base clock keeps sustained multi-threaded jobs fast, while the 5.40 GHz single-core boost keeps lightly-threaded tasks (UI responsiveness, single-stream encoding) snappy. That spread matters on mixed workloads where some threads are maxed out and others are latency-sensitive.
• 64MB L3 Cache: A large L3 pool reduces trips to system memory for working sets that fit in cache — video encoding buffers and database indexing both benefit measurably from more L3 before you're paying full DRAM latency.
• 16MB L2 Cache: Per-core L2 sized for the 16-core layout keeps core-local data close, which helps consistency on workloads with unpredictable memory access patterns like ray tracing or CAD.
• 4nm Process Technology: The smaller process node improves performance-per-watt versus older Threadripper generations, which is relevant if you're rack-mounting a workstation-class board and need to manage thermals in a shared equipment room.
• 350W TDP: A 350W thermal design power figure tells you what cooling solution to budget for — this is not a chip you pair with a stock air cooler. Plan for a high-capacity tower cooler or an AIO liquid loop rated for HEDT/workstation-class TDP, and confirm your case has the airflow to match.
• 95°C (203°F) Max Thermal Temperature: Knowing the throttle point up front lets you validate your cooling solution against real thermal headroom before you commit to a case and cooler combination, rather than discovering a thermal ceiling after the build is running production workloads.
• Socket sTR5: The sTR5 platform is AMD's current Threadripper PRO socket — confirm your motherboard is sTR5-specific before ordering, since it is not backward-compatible with older sTR4/sWRX8 boards.
• Country of Origin — Malaysia: Relevant for procurement teams tracking country-of-origin documentation on government or regulated purchase orders.

Integration & Compatibility

The 9955WX requires an sTR5-socket motherboard and workstation-class power delivery capable of sustaining a 350W TDP under full load — verify your board's VRM rating before pairing it with this chip. Given the core count and cache size, this processor is a reasonable fit for AI-augmented video management systems, multi-camera analytics servers, and rendering or simulation workstations where per-core performance and total thread count both matter. Integrators building out a broader surveillance or IT infrastructure deployment should also review network video recorders and server platforms when this CPU is destined for a recording or analytics backend, and consult a VMS architecture guide when sizing compute against camera count and analytics load. For broader AMD component sourcing, see the AMD catalog, and pair this processor with compatible workstation components such as sTR5 motherboards and high-wattage power supplies sized for a 350W CPU plus discrete GPU headroom.

Frequently Asked Questions

Q: What socket does the AMD 100-100000725WOF use?

James Everett

The 100-100000725WOF is the part number I check for first when a build spec calls for a single-socket workstation with server-class core density — 16 cores and 32 threads at a 4.50 GHz base is a real jump over mainstream desktop silicon once you're running parallel analytics or transcoding jobs.

Technical Highlights:

• 16C/32T on sTR5: Gives you 32 schedulable threads for multi-stream video processing or simulation workloads that scale with core count, on a platform with the memory bandwidth to actually feed them.
• 64MB L3 / 16MB L2 cache: Large cache pools reduce memory-latency stalls on working sets like encode buffers, which shows up directly in sustained multi-stream throughput.
• 5.40 GHz boost / 4.50 GHz base: Keeps single-threaded and lightly-threaded tasks responsive even while other cores are saturated — useful when a workstation is running background analytics alongside interactive work.

Deployment Considerations:

• Budget cooling for a 350W TDP — this is not a stock-cooler chip, and the 95°C (203°F) max thermal ceiling leaves less margin than you'd get from a mainstream desktop part.
• Confirm your motherboard is sTR5-specific before ordering — this socket is not interchangeable with prior-generation Threadripper PRO boards (sTR4/sWRX8).

I'd spec the 100-100000725WOF for a single-socket AI-analytics or video-processing workstation where you need dual-socket-class thread count without the complexity and cost of a two-socket EPYC build.
