The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office applications, web browsing with multiple tabs, and light multitasking well. Heavier applications like large Excel files or multiple browser windows with rich content show some slowdown.
Handles office tasks and heavy browser tabs effortlessly.
Gaming
Not designed for gaming. UHD 64EU can handle older or very light games at low settings, but modern AAA titles are not playable at acceptable frame rates.
Only suitable for very light or older 2D games.
Virtualization
8 threads allow for a lightweight VM alongside host tasks, but this is not a virtualization-focused processor.
Can run a light VM, but core count is low for heavy dev work.
Efficiency
15W TDP with Intel's Dynamic Tuning Technology enables excellent battery life in well-designed laptops, typically 8-12 hours of light use.
Top-tier efficiency, allowing for all-day battery life in ultrabooks.
