CPU Comparison
Intel Core i3-1305U vs Intel Core i3-1315UE
A side-by-side comparison of specs, performance and value. The Intel Core i3-1305U is a 5-core (1P+4E), 6-thread mobile processor with UHD Graphics 64EU, designed for thin-and-light laptops requiring basic computing capability with extended battery life.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office work, web browsing, and document editing without issues. Multi-tab browsing with many heavy sites may show some sluggishness.
Handles office applications, web browsing, and light multitasking smoothly. Stumbles with heavy spreadsheet calculations or large document processing.
Gaming
Not designed for gaming. The UHD 64EU can handle very light casual games at low resolutions but anything beyond that will struggle significantly.
Not designed for gaming. The UHD 64EU can handle very light e-sports titles at low settings but modern AAA games are unplayable.
Virtualization
With only 6 threads, virtualization is impractical for anything beyond the simplest test VMs.
Limited by 6 cores and 15W TDP. Can run a single lightweight VM but not suitable for serious virtualization work.
Efficiency
15W base power with 12W minimum makes this highly efficient for battery-powered laptops, enabling all-day battery life in well-designed chassis.
Excellent power efficiency for its performance class. The hybrid design allows E-Cores to handle background tasks at minimal power draw.
Specialized Performance
AI / ML
- No dedicated AI acceleration hardware
- Single P-core severely limits CPU inference
- Not suitable for any meaningful AI workload
- No dedicated NPU or AI acceleration hardware
- CPU-based inference is slow due to low power budget
- Not suitable for running local AI models
Content Creation
Gaming
- Not designed for gaming workloads
- UHD 64EU is insufficient for modern 3D games
- Single P-core limits CPU-side game performance
- Suitable only for 2D and casual browser games
- 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

Our Verdict on Each
An entry-level mobile chip that prioritizes power efficiency over performance. The unusual 1P+4E configuration makes it adequate for basic tasks but limits its capability for anything beyond everyday computing.
Best for: Only if found in a very inexpensive laptop for strictly basic use cases like web browsing and document editing.
Read the full reviewA 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.
