AMD Ryzen Threadripper Pro 9955WX 4.5 GHz (Shimada Peak) Socket sTR5 - boxed without cooler
With the Threadripper Pro series, AMD brings the ideal workstation to life: hyperthreading, enormous cache memory, high boost clock speeds, and the efficient 4nm FinFET manufacturing process lay the foundation for a powerful workstation PC with the Threadripper CPUs from the “Zen 5” family.
- 16 CPU cores from the "Zen 5" family with a 350-watt TDP
- 32 threads with simultaneous multithreading (SMT)
- Base clock of 4.5 GHz and 5.4 GHz turbo
- Large unified cache memory: combined 80 MB L2 and L3 cache
- Highly efficient 4-nanometre FinFET transistors for CPU cores
- Extensive features and 128 PCIe 5.0 lanes with WRX90 platform
The AMD Ryzen Threadripper PRO 9955WX: 16-core processor for the ideal workstation
For the workstation segment, AMD relies not only on a huge number of cores but also on steadily increasing clock speeds. With Precision Boost, the Threadripper CPU selectively raises individual clock speeds up to 5.4 GHz.
Thanks to the switch to the Zen 5 family and the 4-nanometre FinFET process for the CPU cores, this is achieved with the same die size and thermal design power (TDP) as the predecessor model from the 7000 series.
Furthermore, all PCIe 5.0 lanes are offered as usual so that the Threadripper Pro 9955WX enables mature connectivity. Even in terms of memory, you are particularly well equipped with a maximum of 2 TB DDR5 memory at a maximum clock speed of 6,400 MHz.
AMD Zen 5: CPU cores with 4nm architecture
The Zen 5 generation not only offers the usual range of functions but also higher clock speeds and more instructions per clock cycle (IPC). This means that more instructions are executed per clock, significantly improving CPU performance.
This advantage is made possible by the new manufacturing process, which in turn allows for more transistors per core, while cache and PCIe lanes remain fully intact.
Multithreading (SMT) and Precision Boost Overdrive (PBO)
Thanks to simultaneous multithreading, the Zen 5 cores, as with the previous model, can process two threads simultaneously. The number of cores is effectively doubled to 32 cores with the 16 virtual cores.
Depending on the TDP and cooling conditions, the CPU accelerates its cores up to 5.4 GHz with Precision Boost Overdrive to prioritise important threads and efficiently handle your workload.
Even if the high boost clock of up to 5.4 GHz is not enough for you, AMD has set no limit on the clock speed. This allows you to overclock the CPU as you wish. However, any damage caused by overclocking is not covered by the manufacturer!
Latency-free data access with intelligent cache
It is not only important to have a total cache size of over 80 MB but also one that is intelligently managed. The immense cache of the AMD Ryzen Threadripper Pro 9955WX is managed very efficiently with “Smart-Fetch” algorithms, ensuring latency-free data access and fast calculations.
The CPUs are also enhanced with many other algorithms, instruction sets, and units such as AVX 2 for complex vector calculations or two AES units for fast and reliable data encryption.
