CPU Comparison
Intel Core i9-14900KS vs Intel Core Ultra 9 285K
A side-by-side comparison of specs, performance and value. The Intel Core i9-14900KS is a special-edition 24-core (8P+16E), 32-thread desktop processor built on Intel’s Raptor Lake Refresh architecture, offering up to 6.2 GHz turbo frequencies out of the box for enthusiasts and overclockers willing to manage high power and thermals.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Very strong multi-threaded performance for video editing, rendering and compiling, with small gains over the 14900K in heavily threaded workloads.
24 cores crush heavy multi-threaded workloads like rendering.
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.
Top-tier gaming performance, easily pushing high refresh rates.
Virtualization
24 cores and 32 threads handle multiple VMs well, but power and thermals become a concern under sustained all-core loads.
Excellent for complex virtualization and containerization.
Efficiency
High power draw and temperatures even at stock, especially under multi-core workloads; requires top-tier cooling and a robust PSU.
Efficient at idle, but can draw up to 250W under full load.
Specialized Performance
AI / ML
- 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.
- 13 TOPS NPU handles background AI tasks
- Total 36 TOPS combined with CPU and GPU
- Suitable for light local AI inference
Content Creation
Gaming
- 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.
- High single-core boost ensures maximum FPS
- Performs exceptionally well in CPU-bound scenarios
- Requires a high-end GPU to avoid bottlenecks
