The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office applications, web browsing, and light multitasking smoothly. Stumbles with heavy spreadsheet calculations or large document processing.
Snappy for office apps and web browsing.
Gaming
Not designed for gaming. The UHD 64EU can handle very light e-sports titles at low settings but modern AAA games are unplayable.
Only suitable for very old or lightweight 2D games.
Virtualization
Limited by 6 cores and 15W TDP. Can run a single lightweight VM but not suitable for serious virtualization work.
Not recommended due to low core count.
Efficiency
Excellent power efficiency for its performance class. The hybrid design allows E-Cores to handle background tasks at minimal power draw.
Excellent efficiency for all-day battery life.
Specialized Performance
AI / ML
- No dedicated NPU or AI acceleration hardware
- CPU-based inference is slow due to low power budget
- Not suitable for running local AI models
- 11 TOPS NPU included
- Good for background blur and noise cancellation
- Not for heavy AI generation
Content Creation
Gaming
- UHD Graphics 64EU is not a gaming GPU
- Can manage older 2D games and very light e-sports at 720p low
- No dedicated VRAM limits texture quality severely
- Modern games will experience severe bottlenecking
- 48EU graphics is entry-level
- Fine for browser games
- Not suitable for modern 3D titles

Our Verdict on Each
A capable low-power hybrid processor that brings Intel's P-Core and E-Core design to the entry-level mobile segment, though its 15W base power envelope limits sustained performance under heavy workloads.
Best for: Purchasing a pre-built thin-and-light laptop where this CPU is included by the OEM.
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.
