The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Snappy performance for everyday office tasks and multitasking.
Handles word processing and spreadsheets effortlessly, but heavily multitasked office environments will expose the 2-core limitation.
Gaming
Capable of playing e-sports titles and older games at 1080p thanks to Iris Xe graphics.
The Iris Xe iGPU can handle older or 2D indie games at low settings, but modern AAA titles are unplayable.
Virtualization
Can handle light virtualization but is limited by 4 cores.
2 cores and 4 threads are insufficient for running anything beyond a single, very lightweight virtual machine.
Efficiency
Excellent power efficiency due to the 10nm SuperFIN process.
The configurable 12W-28W TDP range allows OEMs to tune it for excellent battery life in thin chassis designs.
Specialized Performance
AI / ML
- DLBoost and GNA 2.0 provide solid AI acceleration for background blur and noise cancellation.
