CPU Comparison
AMD Ryzen Threadripper PRO 9975WX vs AMD Ryzen Threadripper PRO 9985WX
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.
Exceptional multi-threaded performance for professional applications; competes with or exceeds top Xeon workstation CPUs in many rendering and compilation workloads.
Gaming
Capable of high-refresh-rate gaming at 1440p and 4K in CPU-heavy titles, but not its focus; mainstream high-end desktop CPUs often match or beat it in gaming while costing far less.
Virtualization
Excellent for running many VMs or containers simultaneously, thanks to 128 threads, 8-channel memory, and massive PCIe connectivity.
Efficiency
Delivers high performance at a 350 W TDP; workstation-class efficiency relative to workload size.
High absolute performance but also high power draw; efficiency per watt is not a strength versus lower-core mainstream or server alternatives.
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.
- Good for CPU-based AI inference and model development, especially with 8-channel memory bandwidth.
- Lacks dedicated matrix or AI accelerators found in some newer server and workstation CPUs.
- Best for hybrid workflows combining local CPU inference with remote GPU or cloud acceleration.
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-thread performance thanks to Zen 5 and 5.4 GHz boost.
- More than capable for 1440p/4K gaming with a high-end GPU.
- Significantly more expensive and power-hungry than gaming-focused desktop CPUs.
- Best suited for gaming as a secondary task on a workstation that also does heavy compute.
