CPU Comparison
Intel Core Ultra 5 225F vs Intel Core Ultra 5 245K
A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 225F is the most affordable entry point into the Arrow Lake-S desktop platform, launched at $231 on January 7, 2025. It features a reduced core configuration of 6 Lion Cove P-cores and 4 Skymont E-cores for a total of 10 cores and 10 threads, along with a smaller 20 MB L3 cache compared to the 24 MB found on higher-tier Ultra 5 models. As an F-series processor, the integrated graphics are completely disabled, making a discrete GPU mandatory for any display output. This cost reduction allows Intel to position the 225F as a budget-friendly option for gamers and productivity users who already own or plan to purchase a dedicated graphics card. Despite the reductions, the 225F retains the NPU 3 with 13 TOPS for AI workloads, PCIe 5.0 support, and DDR5-6400 native memory speeds. With a standard 65W TDP and PL1, and a 121W PL2 for boost, it delivers straightforward power characteristics that are easy to pair with mainstream cooling solutions. The processor is available in two part numbers corresponding to A0 and B0 steppings.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
10 cores handle light to moderate productivity well, but the reduced E-core count and smaller L3 cache limit performance in heavily multi-threaded applications.
14 cores with 159W power headroom handle demanding productivity workloads well, though it sits below Core Ultra 7 and 9 models in heavily threaded tasks.
Gaming
With a capable discrete GPU, the 6 P-cores provide sufficient performance for most gaming scenarios. The 4.9 GHz boost keeps frame rates competitive, though fewer E-cores slightly impact heavily threaded titles.
The 5.2 GHz boost and strong IPC of Lion Cove deliver excellent gaming performance, particularly at 1080p where CPU limits are most apparent.
Virtualization
Limited by 10 cores and 20 MB cache, making it adequate for 2-3 VMs but not ideal for heavy virtualization workloads.
Good for running multiple VMs with the 14-core configuration and high power budget supporting sustained multi-threaded loads.
Efficiency
The 3 nm process and 65W TDP deliver strong efficiency, comparable to other Arrow Lake-S models with similar power profiles.
Significantly more efficient than previous-generation K-series processors like the 14600K, thanks to the 3 nm process, though 159W PL2 is still substantial.
Specialized Performance
AI / ML

Content Creation
Gaming
- 6 P-cores with 4.9 GHz boost handle most games well when paired with a mid-range GPU
- No iGPU means a discrete GPU is absolutely required
- Performance is largely GPU-bound at 1440p and above
- Fewer E-cores may reduce 1% low frame rates in CPU-heavy titles
- 5.2 GHz boost provides leading single-threaded performance in the Ultra 5 family
- 64EU iGPU can handle light gaming at 720p/1080p low settings if needed
- Strong 1% low frame rates thanks to high P-core clocks
- Optimal pairing with mid-to-high-end GPUs like RTX 4070 or above
- Overclocking can further improve minimum frame rates
