The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for lightweight office work and web browsing.
Adequate for word processing and spreadsheets but slow with modern web applications.
Gaming
Not suitable for modern 3D games.
Intel HD 3000 cannot handle modern games. Only legacy titles at minimum settings are playable.
Virtualization
Supports VT-x and VT-d but only 2 cores limit practical virtualization use.
Efficiency
Standard 35W mobile power draw for 2011.
35 W TDP is modest for 2011 but inefficient compared to any modern mobile processor.
Specialized Performance
AI / ML
- No AI-specific hardware
- Cannot execute modern ML inference workloads
Content Creation
Gaming
- Outdated architecture
- Weak iGPU
- No modern graphics API support
- Intel HD 3000 limited to DirectX 10.1
- Unsuitable for any game released after 2013

Our Verdict on Each
Identical in performance to the BGA variant, but highly prized today by tinkerers because its rPGA988B socket allows for easy swapping and upgrades to i7 processors.
Best for: Upgrading an existing Socket G2 laptop to an i7
Read the full reviewFunctionally identical to the rPGA variant in performance, but the BGA packaging means it cannot be upgraded or replaced, which is a significant limitation for long-term usability.
Best for: None, as the BGA variant cannot be purchased separately for upgrades
