The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Struggles with modern web applications and heavy office suites.
Handles basic office tasks but struggles with large spreadsheets, heavy documents, or multitasking with many browser tabs.
Gaming
Unable to play modern AAA games at acceptable frame rates.
Cannot run modern AAA titles. Only suitable for very old or lightweight games at low resolutions.
Virtualization
Can run a single lightweight VM but lacks the cores and memory bandwidth for serious virtualization.
Efficiency
32nm process is highly inefficient by today's standards.
35 W TDP is high by modern mobile standards; current chips deliver far more performance per watt.
