Intel Core Ultra 5 245KF vs Core Ultra 7 265KF
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.
Excellent multi-core performance for rendering and compilation.
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.
Identical gaming performance to the 265K when paired with a high-end GPU.
Virtualization
20 cores provide ample resources for VMs.
Efficiency
Better idle and light-load efficiency than 13th/14th Gen due to the 3nm compute tile, but 125W/159W power limits are substantial.
Improved efficiency over 14th Gen, though still draws significant power under load.
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
- 13 TOPS NPU for background AI tasks
- Total 25 TOPS combined Int8 performance
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
- Requires a dedicated graphics card
- High frame rate capabilities in modern titles
- Good 1% low performance

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 reviewThe 265KF offers the same excellent CPU performance as the 265K at a lower price, provided you already own a dedicated graphics card.
Best for: The Core Ultra 7 265KF is an excellent choice if you are building a new PC and already plan to use a dedicated graphics card. It offers the exact same CPU and NPU performance as the 265K but at a lower price point. However, you must have a discrete GPU installed to get any display output, which is standard for most gaming builds anyway. It is highly recommended for gamers and content creators who want to save a few dollars without sacrificing processing power. Pair it with a Z890 motherboard and a high-end GPU to create a top-tier gaming or productivity machine.
