The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Can handle legacy office applications but will struggle with modern web apps and multitasking.
Extremely slow by modern standards for any productivity application.
Gaming
Intel HD 2000 graphics are completely insufficient for any modern 3D gaming.
Cannot run modern games at playable frame rates. Only suitable for pre-2010 titles.
Virtualization
VT-d and VT-x support are present, but four threads limit practical virtual machine usage.
Two cores with Hyper-Threading offer minimal utility for virtualization.
Efficiency
Impressive efficiency for a 2011 quad-core desktop chip, though modern chips are far more efficient.
73W TDP for two cores is poor efficiency compared to modern chips.
Specialized Performance
AI / ML
- No AI acceleration hardware
- Lacks AVX2 and modern matrix math instructions
