AMD Ryzen Threadripper Pro 9955WX 4.5GHz Processor 16 Core for Socket sTR5 in Box

Key features:

  • Zen 5 Microarchitecture
  • 32 Threads
  • Maximum Frequency 5.4 GHz
  • Unlocked
  • Thermal Design Power (TDP) 350 W
See full description

  • CPU Speed

    The speed at which the processor operates in everyday use.

    During the execution of demanding applications (e.g. games), the frequency may automatically increase up to the Maximum Processor Frequency.

  • Cores

    The natural individual processing units that the processor has. The more cores a processor has, the more efficient it is in running multiple applications simultaneously. For simple use, 4 cores are sufficient, while for gaming and video processing, at least 6 are recommended.

  • Socket

    The processor socket type.

    The motherboard we choose should have the same socket in order for the processor to "fit in".

  • Maximum CPU Speed

    The maximum processor frequency is the frequency that the processor can reach when executing demanding applications that use one core. Generally, when running demanding applications (e.g. games), the frequency can automatically increase up to the Maximum Processor Frequency depending on the number of cores in use. (the fewer cores are active, the closer they can operate to the maximum frequency)

  • Unlocked

    Ability to change the processor clock settings to achieve higher operating frequency (overclocking).

  • Cache Memory

    Cache is a very fast memory that acts as an intermediary between the processor and RAM. It stores data that is frequently useful to the processor for faster access.

Comparison with the Previous Generation

Based on the latest 4nm "Zen 5" architecture, this new family of processors for professional workstations offers a full range of computing power, advanced memory capacity, future-ready scalability, and a generous array of PCIe®5.0 to help accelerate performance, simulations, and local AI workload processing.

These architectural improvements translate into a significant increase in IPC compared to previous generations. In fixed frequency comparisons with AMD Ryzen™ Threadripper™ 7000 Series processors, the AMD Ryzen Threadripper 9000 Series processors deliver a geometric increase of 16% across all workstation benchmarks and up to 25% in SPEC workstation AI and ML.

Raw power for extreme workloads

The Threadripper PRO 9000 incorporates the best in high-performance processors thanks to the Zen 5 architecture. This immense power, combined with phenomenal cache memory, makes it easy to handle the most complex projects: 3D rendering, physics simulation, massive compiling, or scientific calculations.

With a frequency of up to 5.4 GHz, it ensures extremely fast execution even of the heaviest commands. This processor is a strategic choice for accelerating all your professional workflows, while maintaining perfect stability and cutting-edge energy efficiency.

A platform designed for creators

Optimized for professional applications, this processor excels in software such as Autodesk Maya, V-Ray, Keyshot, and Revit, with performance gains that can exceed +120% depending on the workload (depending on the model). Support for DDR5-6400 ECC 8-channel memory guarantees massive bandwidth and high stability, essential for heavy or collaborative projects.

Thanks to the large number of PCIe 5.0 lanes, it offers excellent connectivity for multiple graphics cards and ultra-high-speed NVMe SSDs. It is the ideal foundation for a multifunctional, highly upgradable workstation, capable of meeting the challenges of today and tomorrow.

A machine of innovation for professionals

The Threadripper PRO transforms creative work environments thanks to its exceptional multitasking capability and efficiency in AI-based tasks. Ideal for LLM model inference, compiling complex projects (Unreal Engine, Chromium), or intensive computational processing with Matlab, it is an indispensable technological ally.

It provides professionals with the means to turn their ideas into reality without compromise or slowdown. It is an extremely reliable solution, designed to support creative studios, design offices, and laboratories in all their ambitions for performance and innovation.
