Performance Compared

Productivity

Intel Core i5-540MBest30

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

Core i7-620UE5

Extremely slow for modern software.

Gaming

Intel Core i5-540MBest15

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

Core i7-620UE2

No 3D capabilities.

Virtualization

Intel Core i5-540MBest12

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

Core i7-620UE10

ECC support helps, but lacks cores and speed.

Efficiency

Intel Core i5-540MBest40

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

Core i7-620UE15

Good for 2010, obsolete now.
