CPU Comparison
AMD Ryzen Threadripper PRO 9975WX vs Intel Xeon w7-3555
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 professional applications; 28 P‑cores with high turbo frequencies and ample cache make short work of rendering, compiles, and data processing.
Gaming
Competent at high refresh 1080p/1440p gaming thanks to strong single‑thread clocks, but not a rational choice for pure gaming builds due to high cost and power draw compared to mainstream CPUs.
Virtualization
Excellent for workstation‑class virtualization with many vCPUs, thanks to 56 hardware threads, large memory support, and extensive I/O.
Efficiency
Delivers high performance at a 350 W TDP; workstation-class efficiency relative to workload size.
325 W base and 390 W turbo power result in high energy use and cooling requirements; efficiency is acceptable only if the I/O and core count are fully utilized.
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.
- AMX and AVX‑512 provide strong CPU‑side matrix and inference acceleration.
- No dedicated NPU; AI workloads rely on CPU + GPU combination.
- Excellent for AI development and small‑scale training where multi‑GPU and large memory matter more than pure CPU TOPS.
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.
- Strong single‑core turbo up to 4.8 GHz benefits high‑FPS gaming.
- Lack of hybrid E‑cores avoids scheduling oddities compared to client CPUs.
- Cost and power make it hard to recommend over gaming‑focused desktop CPUs.
- Best paired with high‑end GPU for GPU‑bound titles where CPU overhead matters.
