CPU Comparison
Intel Core i5-540M vs Core i7-620M
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.
Struggles with modern web and office software.
Gaming
Cannot handle any modern 3D games. Only suitable for very old or browser-based titles.
Can run very old games, but lacks modern instructions.
Virtualization
Two cores with 3MB L3 cache are insufficient for any practical VM workloads.
Can run basic VMs but lacks RAM support.
Efficiency
35W TDP was reasonable for 2010 but is far less efficient than modern mobile chips.
35W for 2 cores is inefficient by modern standards.
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
- Ironlake graphics are too weak; relies on discrete GPUs. Lacks AVX2.

Read the full reviewFrequently Asked Questions
Do Intel Core i5-540M and Core i7-620M use the same socket?
No. They use different sockets (Intel Core i5-540M: Intel BGA 1288, Core i7-620M: Socket G1 (rPGA988A)), so each needs a compatible motherboard.
Which is faster in multi-core benchmarks?
The Core i7-620M posts the highest multi-core benchmark score. Multi-core results: Intel Core i5-540M (1,830), Core i7-620M (2,200). Benchmark figures are approximate and workload-dependent.
