The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for lightweight office work and web browsing.
Handles basic office tasks but struggles with large spreadsheets, heavy documents, or multitasking with many browser tabs.
Gaming
Not suitable for modern 3D games.
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
Standard 35W mobile power draw for 2011.
35 W TDP is high by modern mobile standards; current chips deliver far more performance per watt.
Specialized Performance
AI / ML
- No AI acceleration instructions
- No NPU or matrix multiplication support
- Cannot run modern AI workloads
Content Creation
Gaming
- Outdated architecture
- Weak iGPU
- Intel HD 3000 lacks modern API support
- No DirectX 12 or Vulkan support
- Only playable with pre-2012 titles at low settings
