CPU Comparison
Intel Core i5-2540M (BGA) vs Core i7-620M
A side-by-side comparison of specs, performance and value. The Intel Core i5-2540M BGA variant is a ball-grid-array version of the same Sandy Bridge dual-core chip, soldered directly to the motherboard and commonly found in thinner laptops where socketed CPUs were not feasible.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for word processing and spreadsheets but slow with modern web applications.
Struggles with modern web and office software.
Gaming
Intel HD 3000 cannot handle modern games. Only legacy titles at minimum settings are playable.
Can run very old games, but lacks modern instructions.
Virtualization
Supports VT-x and VT-d but only 2 cores limit practical virtualization use.
Can run basic VMs but lacks RAM support.
Efficiency
35 W TDP is modest for 2011 but inefficient compared to any modern mobile processor.
35W for 2 cores is inefficient by modern standards.
Specialized Performance
AI / ML
- No AI-specific hardware
- Cannot execute modern ML inference workloads
- No AI capabilities.
Content Creation
Gaming
- No modern graphics API support
- Intel HD 3000 limited to DirectX 10.1
- Unsuitable for any game released after 2013
- Ironlake graphics are too weak; relies on discrete GPUs. Lacks AVX2.
