CPU Comparison
Intel Core 5 120U vs Intel Core Ultra 5 115U
A side-by-side comparison of specs, performance and value. A 15-watt, 10-core (2P+8E) mobile processor from Intel’s Core (Series 1) lineup built on the Intel 7 process. It pairs high P-core boost clocks up to 5.0 GHz with an 80 EU Iris Xe iGPU, dual-channel DDR4/DDR5 or LPDDR4x/LPDDR5 memory, and up to 20 total PCIe lanes, targeting everyday thin-and-light laptops.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office suites, browsers with many tabs, and light creative workflows well. Multi-thread performance is limited by the 15W PL1 and lack of Hyper-Threading on E-cores.
Snappy for office apps and web browsing.
Gaming
Fine for esports and older/light titles at 1080p with low–medium settings; not intended for AAA gaming at high settings.
Only suitable for very old or lightweight 2D games.
Virtualization
Not recommended due to low core count.
Efficiency
The 15W base power and Intel 7 process help thin-and-lights achieve long battery life in typical office use, especially with LPDDR memory.
Excellent efficiency for all-day battery life.
Specialized Performance
AI / ML
- No dedicated NPU; AI workloads rely on CPU and GPU.
- Intel DL Boost (VNNI) is supported on the CPU, enabling some acceleration for inference.
- Suitable for small-scale, occasional local inference; not intended for heavy AI training or large LLM serving.
- 11 TOPS NPU included
- Good for background blur and noise cancellation
- Not for heavy AI generation
Content Creation
Gaming
- Integrated Iris Xe 80 EU is sufficient for e-sports titles and older games at 1080p.
- Modern AAA titles will generally require low settings and may still struggle; not a gaming-focused part.
- 48EU graphics is entry-level
- Fine for browser games
- Not suitable for modern 3D titles

Our Verdict on Each
A competent 15W chip that delivers snappy day-to-day performance and solid battery life in mainstream laptops, but it’s not built for sustained heavy workloads or AAA gaming. The 2P+8E layout and 5.0 GHz P-core boost are strong for the segment; the 80 EU iGPU handles everyday graphics and light gaming adequately. Choose it for everyday work and study rather than intensive creator tasks.
Best for: Everyday productivity, study, and light creative work in a thin-and-light laptop where battery life and cost matter more than peak multi-core performance.
Read the full reviewA solid entry-level Meteor Lake chip that delivers great battery life and AI features for basic daily tasks.
Best for: The Core Ultra 5 115U is the ideal processor for students, office workers, and casual users who prioritize battery life and affordability. If your daily routine involves document editing, web conferencing, and streaming video, this CPU will handle these tasks effortlessly while providing excellent battery longevity. The integrated NPU adds value by preparing your device for future Windows AI features. However, this is not the processor for video editing, 3D rendering, or gaming; its reduced core count and 48EU graphics are not designed for heavy workloads. If you occasionally dabble in photo editing or light gaming, consider stepping up to the 135U. For purely administrative and educational tasks, the 115U offers outstanding value and efficiency.
