Intel Core i3-1315UE vs Core i5-1340P
A side-by-side comparison of specs, performance and value. The Intel Core i3-1315UE is a 6-core mobile processor featuring a hybrid architecture with 2 P-Cores and 4 E-Cores, designed for thin-and-light laptops and compact embedded systems requiring balanced performance and low power consumption.
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.
Great for heavy Excel, large databases, and corporate software.
Gaming
Not designed for gaming. The UHD 64EU can handle very light e-sports titles at low settings but modern AAA games are unplayable.
Iris Xe can handle older or e-sports titles at low settings.
Virtualization
Limited by 6 cores and 15W TDP. Can run a single lightweight VM but not suitable for serious virtualization work.
12 threads provide enough overhead for local Docker containers.
Efficiency
Excellent power efficiency for its performance class. The hybrid design allows E-Cores to handle background tasks at minimal power draw.
28W TDP offers a great balance of performance and 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
- No NPU; relies on CPU/GPU for AI tasks.
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
- Not intended for AAA gaming without a discrete GPU.
- Iris Xe 80EU is suitable for Minecraft or CS:GO at 1080p Low.
