CPU Comparison
Intel Core i5-2540M vs Intel Core i5-430M
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.
Handles basic office tasks on Windows 7 but struggles with modern web applications and operating systems.
Gaming
Cannot run modern AAA titles. Only suitable for very old or lightweight games at low resolutions.
The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.
Virtualization
Can run a single lightweight VM but lacks the cores and memory bandwidth for serious virtualization.
Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.
Efficiency
35 W TDP is high by modern mobile standards; current chips deliver far more performance per watt.
The dual-die design was less efficient than Sandy Bridge's unified approach. 35 W delivers very little performance by modern standards.

Our Verdict on Each
The i5-2540M was a solid mid-range mobile chip in 2011, but it is now thoroughly outclassed by modern processors in every metric including efficiency, single-thread speed, and integrated graphics capability.
Best for: Upgrading an existing Socket G2 laptop at minimal cost
Read the full reviewThe i5-430M was a competent mid-range laptop CPU in early 2010, but its Arrandale architecture with separate CPU and I/O dies, lack of on-die GPU, and absence of AVX make it thoroughly obsolete today.
Best for: Upgrading an existing Socket G1 laptop with a used i7-620M at minimal cost
