CPU Comparison
Intel Core i3-1215U vs Core i7-620UM
A side-by-side comparison of specs, performance and value. The Intel Core i3-1215U is a 6-core (2P+4E), 8-thread mobile processor built on the Alder Lake-U architecture, featuring UHD Graphics 64EU and a 15W base TDP for mainstream thin-and-light laptops.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles standard office applications and web browsing smoothly. Heavier multitasking with many browser tabs and applications can show some slowdown.
Will struggle immensely with modern web and software.
Gaming
Not designed for gaming. The UHD 64EU can handle very light casual titles but modern AAA games are unplayable.
No modern gaming capabilities.
Virtualization
8 threads allow for a lightweight VM alongside host tasks, but this is not a virtualization-focused part.
Lacks the power for practical virtualization.
Efficiency
The 15W base TDP with Intel's Thread Director scheduler enables efficient power distribution between P and E cores.
Good for 2010, obsolete now.
Specialized Performance
AI / ML
- No dedicated AI acceleration hardware

- Not suitable for AI or ML development workloads
- No AI capabilities.
Content Creation
Gaming
- Not designed for gaming workloads
- UHD 64EU can manage 2D games and very basic 3D
- Modern AAA titles will not run at playable frame rates
- Older eSports titles at lowest settings may be marginally playable
- Ironlake graphics are insufficient for any 3D gaming.
