CPU Comparison
Intel Core i5-540M vs Core i7-620UE
A side-by-side comparison of specs, performance and value. The Intel Core i5-540M is a dual-core mobile processor built on the 32nm Arrandale architecture, featuring Hyper-Threading, Turbo Boost, and an integrated GPU die, designed for mainstream laptops in early 2010.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Basic office tasks remain functional, but anything beyond simple documents will feel slow.
Extremely slow for modern software.
Gaming
Cannot handle any modern 3D games. Only suitable for very old or browser-based titles.
No 3D capabilities.
Virtualization
Two cores with 3MB L3 cache are insufficient for any practical VM workloads.
ECC support helps, but lacks cores and speed.
Efficiency
35W TDP was reasonable for 2010 but is far less efficient than modern mobile chips.
Good for 2010, obsolete now.
Specialized Performance
AI / ML
- No AI acceleration instructions
- No AVX support
- Completely unsuitable for any AI workload
- No AI capabilities.
Content Creation
Gaming
- Integrated Intel HD Graphics (first gen) is extremely limited
- No dedicated VRAM, shares system memory
- Unplayable in any modern game title
- May run pre-2010 games at low settings
- Integrated graphics are strictly for display output.
