Performance Compared

Productivity

Intel Core i5-2540MBest35

Handles basic office tasks but struggles with large spreadsheets, heavy documents, or multitasking with many browser tabs.

Intel Core i5-430M25

Handles basic office tasks on Windows 7 but struggles with modern web applications and operating systems.

Gaming

Intel Core i5-2540MBest15

Cannot run modern AAA titles. Only suitable for very old or lightweight games at low resolutions.

Intel Core i5-430M8

The chipset-based GMA HD graphics are weaker than even Sandy Bridge's HD 3000. Not viable for any meaningful gaming.

Virtualization

Intel Core i5-2540MBest20

Can run a single lightweight VM but lacks the cores and memory bandwidth for serious virtualization.

Intel Core i5-430M15

Supports VT-x and VT-d but only 2 cores at relatively low clocks make it impractical.

Efficiency

Intel Core i5-2540MBest25

35 W TDP is high by modern mobile standards; current chips deliver far more performance per watt.

Intel Core i5-430M20

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
