CPU Comparison
AMD Ryzen Threadripper PRO 9945WX vs Intel Core i9-14900KS
A side-by-side comparison of specs, performance and value. The AMD Ryzen Threadripper PRO 9945WX is a 12-core, 24-thread workstation processor designed for professionals who require extreme single-threaded performance, eight-channel memory bandwidth, and full I/O expandability but do not need the core counts of higher-tier chips.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Exceptional for single-threaded tasks, though multi-threaded throughput is naturally lower than 32 or 64-core models.
Very strong multi-threaded performance for video editing, rendering and compiling, with small gains over the 14900K in heavily threaded workloads.
Gaming
One of the fastest gaming CPUs at launch, but only marginally quicker than the cheaper i9-14900K; AMD Ryzen 7000X3D chips often still lead in many titles.
Virtualization
24 cores and 32 threads handle multiple VMs well, but power and thermals become a concern under sustained all-core loads.
Efficiency
With only 12 active cores, power efficiency is excellent relative to the workload, fitting well within the 350W envelope.
High power draw and temperatures even at stock, especially under multi-core workloads; requires top-tier cooling and a robust PSU.
Specialized Performance
AI / ML
- Limited by 12 cores for parallel AI tasks.
- However, PCIe 5.0 lanes allow for massive accelerator arrays.
- Intel Deep Learning Boost (AVX2 VNNI) accelerates some CPU-based inference workloads.
- No dedicated NPU; for serious local AI, modern NPUs or discrete GPUs are faster and more efficient.
Content Creation
Gaming
- Boosts up to 5.7 GHz, rivaling top-tier consumer CPUs.
- Ideal for high-refresh-rate gaming workstations.
- Supports multiple GPUs via extensive PCIe lanes.
- 6.2 GHz P-core turbo and strong IPC deliver very high FPS at 1080p and 1440p.
- Only ~1.7% faster than i9-14900K at 1080p and ~2.5% at 1440p in some reviews.
- AMD Ryzen 7000X3D models still often lead in CPU-limited gaming scenarios.

Target Audience
Strengths & Weaknesses
Pros
- Highest clock speeds in the Threadripper PRO 9000 lineup.
- Retains full 8-channel memory and 144 PCIe 5.0 lanes.
- Excellent single-threaded performance for professional apps.
- Lower power consumption and thermal output compared to 64/96-core models.
- Unlocked multiplier for extensive overclocking.
Cons
- Only 12 cores limit multi-threaded throughput.
- High platform cost (WRX90 motherboard) for a 12-core CPU.
- Diminishing returns for users who don't utilize the workstation features.
- No integrated graphics.
Pros
- 6.2 GHz max turbo – highest stock desktop clock speed at launch
- Strong single-thread and gaming performance
- 24 cores and 32 threads for heavy multi-tasking and productivity
- Unlocked multiplier and flexible power limits for overclocking
- PCIe 5.0 and DDR5 support for a modern platform
Cons
- High power draw: 150 W base, up to 253 W turbo, and often 300–350 W in tuned systems
- Runs hot under load; can hit 100°C even with high-end AIOs if power limits are left unlimited
- Small real-world gains over the cheaper i9-14900K in most workloads
- Premium price with questionable price-performance ratio
- No significant architectural upgrade vs 13th Gen; still a refreshed Raptor Lake design

Our Verdict on Each
The 9945WX is a niche but compelling option for professionals whose workflows are frequency-sensitive rather than heavily parallelized. It brings the platform benefits of Threadripper PRO—like 128 PCIe lanes and eight-channel memory—to a lower core count and price point.
Best for: For CAD engineers, software developers, and finance professionals who need the reliability and I/O of a Threadripper PRO but do not require high core counts.
Read the full reviewIntel’s fastest-ever LGA 1700 desktop CPU by clock speed, but real-world gains over the cheaper i9-14900K are modest, and power/thermals are punishing. A niche choice for overclockers and enthusiasts who must have the top bin.
Best for: You are an extreme overclocker or enthusiast building a showpiece LGA 1700 system and are willing to pay a significant premium for Intel’s best-binned silicon and guaranteed 6.2 GHz capability.
