Performance Compared

Productivity

Intel Core i5-540MBest30

Basic office tasks remain functional, but anything beyond simple documents will feel slow.

Core i7-620M15

Struggles with modern web and office software.

Gaming

Intel Core i5-540M15

Cannot handle any modern 3D games. Only suitable for very old or browser-based titles.

Core i7-620M15

Can run very old games, but lacks modern instructions.

Virtualization

Intel Core i5-540M12

Two cores with 3MB L3 cache are insufficient for any practical VM workloads.

Core i7-620MBest20

Can run basic VMs but lacks RAM support.

Efficiency

Intel Core i5-540MBest40

35W TDP was reasonable for 2010 but is far less efficient than modern mobile chips.

Core i7-620M20

35W for 2 cores is inefficient by modern standards.
