CPU Comparison
Intel Core Ultra 5 245KF vs Intel Core Ultra 5 245T
A side-by-side comparison of specs, performance and value. The Intel Core Ultra 5 245KF is a 14-core unlocked desktop processor based on the Arrow Lake-S architecture, featuring 6 P-Cores and 8 E-Cores with a 5.2 GHz boost clock and no integrated graphics.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
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.
Good productivity performance with 14 cores, though the 35W PL1 limits sustained multi-threaded throughput compared to non-T models.
Gaming
Strong 1080p and 1440p gaming performance with the 5.2 GHz boost. Pairs well with GPUs up to RTX 4070 class without significant bottlenecks.
The 5.1 GHz boost and 14 cores provide strong gaming performance when paired with a discrete GPU. The 64EU iGPU can handle light gaming at 720p/1080p low, a significant step up from the 235T's 24EU.
Virtualization
Adequate for several VMs, with ECC memory adding reliability for data-sensitive virtualization workloads.
Efficiency
Better idle and light-load efficiency than 13th/14th Gen due to the 3nm compute tile, but 125W/159W power limits are substantial.
Excellent efficiency during sustained operation at 35W PL1, with the 3 nm process ensuring strong performance per watt.
Specialized Performance
AI / ML
- 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
- 29 TOPS total AI performance, second only to the 245K in Ultra 5
- 64EU iGPU contributes 8 TOPS, double the 235T's 4 TOPS GPU contribution
- NPU 3 provides 13 TOPS for sustained AI tasks
- ECC memory adds reliability for AI workloads processing sensitive data
Content Creation
Gaming
- 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
- 5.1 GHz boost provides strong performance with a discrete GPU
- 64EU iGPU can handle eSports titles and older games at low settings
- E-cores boost to 4.5 GHz, the highest in the Ultra 5 family
- 35W PL1 may reduce performance in very long CPU-bound gaming sessions
- Ideal for SFF gaming builds with compact GPUs

Our Verdict on Each
A 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.
Read the full reviewA uniquely positioned processor that combines premium features (64EU iGPU, ECC support) with T-series power efficiency, ideal for SFF builds that need strong integrated graphics and data integrity.
Best for: Small form factor or power-constrained builds that need the 64EU iGPU for light graphics work, multi-display support, or ECC memory for data integrity, but cannot accommodate K-series power levels.
