CPU Comparison
Intel Core Ultra 5 245 vs Intel Core Ultra 5 245KF
A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 245 is a 14-core mainstream desktop processor featuring the Arrow Lake-S architecture with a locked 65W TDP, designed for users who want modern Arrow Lake efficiency and features without the premium K-series pricing or power draw.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Solid multi-threaded performance from 14 cores, though the 65W power limit reduces sustained throughput compared to 125W siblings.
14 cores provide good multi-threaded performance, though the 8 E-Cores are outpaced by the 250KF Plus's 12 E-Cores in heavily parallel workloads.
Gaming
Handles 1080p gaming adequately when paired with a mid-range discrete GPU, but the lower clocks compared to K-series parts limit frame rates in CPU-bound titles.
Strong 1080p and 1440p gaming performance with the 5.2 GHz boost. Pairs well with GPUs up to RTX 4070 class without significant bottlenecks.
Efficiency
Excellent performance-per-watt thanks to the TSMC 3nm compute tile and conservative power limits.
Better idle and light-load efficiency than 13th/14th Gen due to the 3nm compute tile, but 125W/159W power limits are substantial.
Specialized Performance
AI / ML
- 13 TOPS NPU 3 for lightweight AI tasks
- Combined 29 TOPS with CPU and GPU contributions
- Suitable for background AI features like noise cancellation and image enhancement
- Not designed for training or heavy inference workloads
- 13 TOPS NPU 3 for lightweight AI tasks
- 22 TOPS total without iGPU contribution
- Adequate for Windows Copilot+ features and basic local inference
- Not competitive with dedicated AI accelerators or AMD's newer NPU implementations
Content Creation
Gaming
- 5.1 GHz boost is lower than the 245KF's 5.2 GHz
- Pairs well with GPUs up to RTX 4060 class without bottlenecking
- E-Cores contribute meaningfully in modern game engines
- iGPU can handle older or less demanding titles at low settings
- 5.2 GHz boost provides strong single-thread performance for gaming
- 14 threads handle modern game engines well with background tasks
- No iGPU means discrete GPU is mandatory
- Slightly behind the 250KF Plus due to lower boost and fewer cores

Our Verdict on Each
A sensible locked Arrow Lake chip that trades peak frequency for a modest 65W power envelope, making it ideal for small form factor builds and users who prioritize efficiency over overclocking headroom.
Best for: Building a compact, quiet, power-efficient desktop with modern features like NPU and PCIe 5.0 without paying K-series prices.
Read the full reviewA solid Arrow Lake processor that was reasonably priced at launch but has been made largely redundant by the 250KF Plus, which offers more cores, higher clocks, and faster memory support for $110 less.
Best for: Only if found at a significant discount (under $200) compared to its $294 MSRP.
