AMD Ryzen Threadripper PRO 7965WX
AMD Ryzen Threadripper PRO 7965WX: Power for Professionals
Codename Storm Peak, 5 nm, 24 cores, and uncompromising performance
Key Specifications: Zen 4 Architecture and More
The AMD Ryzen Threadripper PRO 7965WX is a flagship workstation processor built on the Zen 4 architecture and TSMC's 5 nm FinFET process. This ensures high transistor density and energy efficiency, despite a TDP of 350 W.
Key Features:
- 24 cores and 48 threads — perfect for parallel tasks.
- 128 MB L3 cache — reduces latency when working with large data sets.
- PCIe 5.0 support — 128 lanes for fast SSDs and GPUs.
- PRO technologies — ECC memory, remote management, data protection.
Performance:
In Geekbench 6, the processor scores 2686 points in single-threaded and 23294 in multi-threaded modes. For comparison, the Intel Core i9-13900K scores around 3000 in single-threading but only about 22000 in multi-threading. The Threadripper PRO 7965WX excels in scenarios where both types of workloads are important.
Compatible Motherboards: sTR5 and WRX90 Chipsets
The processor uses the sTR5 socket, which requires specialized platforms.
Recommended Chipsets:
- WRX90 — a top-tier solution supporting PCIe 5.0, 8-channel DDR5 memory, and extended overclocking capabilities.
Examples of Motherboards:
- ASUS Pro WS WRX90E-SAGE SE — 7 PCIe 5.0 x16 slots, 8 DDR5 slots, 10 Gbit Ethernet.
- GIGABYTE MC73-WRX90 — focus on reliability and VRM cooling.
Things to Consider:
- VRM Cooling — due to the 350 W TDP, the motherboard must have substantial heatsinks.
- Number of PCIe Slots — essential for multi-processor configurations with GPUs or NVMe drives.
Memory: 8-channel DDR5
The Threadripper PRO 7965WX supports DDR5 with speeds of up to 5200 MHz in 8-channel mode. This provides bandwidth of up to 166 GB/s, which is critical for rendering tasks, modeling, and database work.
Recommendations:
- Use DDR5 ECC kits — for example, Kingston Fury Renegade DDR5-5200.
- Minimum capacity is 64 GB (8x8 GB), but for professional tasks, 128 GB or 256 GB is preferable.
Power Supply: Minimum 1000 W
With a TDP of 350 W, the processor requires a serious approach to power.
Recommendations:
- Power: At least 1000 W (e.g., Corsair HX1200).
- Certification: 80+ Platinum or Titanium for stability under load.
- Cable Management: Separate 12+4-pin EPS connectors for the CPU.
Important: When using multiple GPUs (e.g., NVIDIA RTX 4090), the PSU power should be 1200–1500 W.
Pros and Cons
Advantages:
- Best-in-class multi-threaded performance.
- Support for PCIe 5.0 and DDR5.
- Reliability for workstations (ECC, overheating protection).
Disadvantages:
- High price (starting from $2500).
- Limited compatibility (only WRX90 motherboards).
- Overkill for everyday tasks.
Use Cases
1. Rendering and 3D Modeling
- Example: In Blender, rendering a scene takes 8 minutes compared to 12–15 minutes with the Ryzen 9 7950X.
2. Scientific Computing
- MATLAB or Ansys Mechanical — accelerates simulations by 30–40% compared to the previous generation.
3. Virtualization
- Running 10+ virtual machines without performance loss.
4. Gaming
- Not the best choice: high latency due to NUMA architecture. However, in 4K with RTX 4090, it achieves 120+ FPS in AAA titles.
Comparison with Competitors
Intel Xeon W7-2495X (24 cores):
- Falls short in multi-threaded tests (~21000 in Geekbench 6 Multi).
- No PCIe 5.0 support.
- Comparable price, but lower performance.
AMD Threadripper PRO 5975WX (32 cores):
- More cores, but Zen 3 vs Zen 4: 7965WX is 15-20% faster in single-threaded tasks.
Assembly Tips
1. Cooling:
- Liquid cooling solution with a TDP of 350 W (e.g., NZXT Kraken Z73).
- Case with good ventilation (Lian Li PC-O11 Dynamic).
2. Additional Components:
- Graphics Card: NVIDIA RTX 6000 Ada for workstation tasks or RTX 4090 for hybrid builds.
- Storage: Samsung 990 Pro 2 TB (PCIe 5.0).
3. Testing:
- Check stability in AIDA64 and Prime95 during the first 24 hours.
Final Conclusion: Who is this Processor For?
The AMD Ryzen Threadripper PRO 7965WX is the choice for professionals who need maximum performance in:
- 3D rendering,
- Engineering modeling,
- Scientific research,
- Server tasks.
It is not suited for gamers or users who are satisfied with 8–16 cores. This is a tool for those who value time and are willing to invest in hardware that pays off through speed.
If your project requires processing 8K video, simulating physical processes, or running dozens of virtual machines — Storm Peak will be your reliable partner.
