A side-by-side comparison of specs, performance and value. The Intel Core 3 N350 is an ultra-low-power 8-core mobile processor built on the Alder Lake-N architecture, featuring a 7W TDP and integrated UHD Graphics 770 for entry-level laptops and Chromebooks.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles word processing and spreadsheets effortlessly, but struggles with large macros or heavy databases.
Handles standard office suites flawlessly, but the 6-thread limit causes slowdowns in heavy spreadsheet calculations or large file processing.
Gaming
Lacks the memory bandwidth and core power required for modern AAA or competitive esports titles.
While Xe3 graphics are powerful, the single-channel memory bottleneck severely limits frame rates in modern 3D games.
Virtualization
Not suitable for running virtual machines due to low core performance and limited memory channels.
Can run light VMs for development or testing, but limited core count and memory bandwidth constrain heavier workloads.
Efficiency
Exceptional efficiency that enables all-day battery life in portable devices.
The 3nm compute tile and lack of SMT result in class-leading performance-per-watt for everyday tasks.
Specialized Performance
AI / ML
- Lacks a dedicated NPU
- VNNI instructions provide minimal acceleration for local AI workloads
- AI tasks should be offloaded to the cloud
- Meets the 40+ TOPS requirement when including CPU and GPU contributions
