CPU Comparison
AMD Ryzen Threadripper PRO 9975WX vs Intel Xeon w9-3575X
A side-by-side comparison of specs, performance and value. The AMD Ryzen Threadripper PRO 9975WX is a 32-core, 64-thread workstation processor built on the Zen 5 architecture, featuring eight-channel DDR5 memory, 128 PCIe 5.0 lanes, and a 350 W TDP for professional workloads.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
High multi-thread throughput accelerates compilation, rendering, and simulation tasks.
Very strong multi-threaded performance for content creation and engineering workloads, with Puget’s W-3500 review showing ~10–15% gains over previous-generation Xeon W-3400 in many heavily threaded tasks.
Gaming
Not a gaming CPU; capable of high refresh-rate gameplay but significantly outperformed by modern gaming-focused desktop CPUs at much lower power.
Virtualization
Excellent for multi-VM workloads thanks to 44 cores, 8-channel memory, and VT-x/VT-d/VT-rp support, though AMD Threadripper PRO often leads at the top end.
Efficiency
Delivers high performance at a 350 W TDP; workstation-class efficiency relative to workload size.
High power consumption (340 W base, up to 408 W turbo) makes it relatively inefficient compared to newer architectures, requiring robust cooling and power delivery.
Specialized Performance
AI / ML
- AVX-512 support accelerates vectorized compute; suitable for CPU-based inference and training.
- PCIe 5.0 lanes and memory bandwidth help feed multiple accelerators in workstation setups.
- For large-scale training, dedicated GPUs remain the primary compute engines.
- Intel AMX and AVX-512 provide strong CPU-based AI inference and HPC potential.
- No dedicated AI accelerator like a discrete GPU or NPU, so large-scale training still requires GPUs.
- Well-suited for inference, scientific computing, and some HPC workloads that can leverage AMX/BF16.
Content Creation
Gaming
- Strong single-core clocks and modern architecture handle high-refresh gaming well.
- Workstation platforms lack consumer-focused optimizations, but gaming is still capable.
- Best paired with discrete GPUs; no integrated graphics present.
- Single-thread performance is good, but not class-leading compared to modern gaming CPUs.
- Very high power and platform cost for a gaming-focused build.
- Best used as a workstation CPU that also games, not the reverse.

Much cheaper and more efficient for gaming and light content creation, but with fewer cores and fewer PCIe lanes; best when you don’t need workstation-class I/O.
Our Verdict on Each
A highly capable 32-core workstation processor with strong per-core performance and massive I/O, ideal for professionals who need many PCIe lanes and eight-channel memory, though high power draw and platform cost require careful planning.
Best for: Professional workstation requiring many cores, high I/O, and large memory bandwidth for simulations, 3D, or development.
Read the full reviewA potent workstation CPU with excellent multi-threaded performance and massive I/O, but high power consumption and cost limit its appeal to users who genuinely need 44 cores and 112 PCIe lanes.
Best for: High-end single-socket workstation for 3D rendering, engineering simulation, or AI inference where you need 44+ cores and 112 PCIe lanes but not the absolute top core count.
