CPU Comparison
Intel Core i5-2540M vs Core i7-620M
A side-by-side comparison of specs, performance and value. The Intel Core i5-2540M is a dual-core mobile processor built on the 32nm Sandy Bridge architecture, featuring Hyper-Threading for four threads and an integrated Intel HD 3000 GPU, designed for mainstream laptops released in early 2011.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office tasks but struggles with large spreadsheets, heavy documents, or multitasking with many browser tabs.
Struggles with modern web and office software.
Gaming
Cannot run modern AAA titles. Only suitable for very old or lightweight games at low resolutions.
Can run very old games, but lacks modern instructions.
Virtualization
Can run a single lightweight VM but lacks the cores and memory bandwidth for serious virtualization.
Can run basic VMs but lacks RAM support.
Efficiency
35 W TDP is high by modern mobile standards; current chips deliver far more performance per watt.
35W for 2 cores is inefficient by modern standards.
Specialized Performance
AI / ML
- No AI acceleration instructions
- No NPU or matrix multiplication support
