Ryzen Threadripper PRO 5955WX

The Ryzen Threadripper PRO 5955WX is a 16-core / 32-thread processor based on the Chagall PRO (2022) architecture, manufactured on a 7 nm process node. It reaches a maximum boost clock of 4.5 GHz from a base frequency of 4 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 64 MB of L3 cache, plus 512K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 48,756, placing it in the Enthusiast performance tier as a Aging generation product.

The Ryzen Threadripper PRO 5955WX fits into the sWRX8 socket and supports PCIe 4.0 with 128 total PCIe lanes for expansion cards and storage. It supports DDR4-3200 memory at speeds up to 3200 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 2048 across 8 channels (dual-channel doubles bandwidth). It supports ECC memory, providing error-correcting capabilities — essential for mission-critical workloads and servers. Integrated graphics: None — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

It features an unlocked multiplier, allowing enthusiasts to overclock beyond stock frequencies for additional performance. It supports AVX-512 instructions — specialized SIMD operations that significantly accelerate AI inference, scientific computing, and video encoding workloads. Virtualization: VT-x, VT-d, AMD-V — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Xeon w5-3335.

The Ryzen Threadripper PRO 5955WX has a rated TDP (Thermal Design Power) of 280 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately. Recommended cooling: sWRX8 Cooler.

At an average price of $999 (MSRP: $799), the Ryzen Threadripper PRO 5955WX delivers 49 PassMark points per dollar. Performance ranking position: #215 out of all indexed processors.
