Performance Compared

Productivity

Intel Core i5-580MBest36

Highest single-threaded Arrandale i5 performance helps slightly in office tasks, but the difference from lower SKUs is minimal in practice.

Core i7-620M15

Struggles with modern web and office software.

Gaming

Intel Core i5-580MBest19

Identical to the socketed i5-580M. First-gen Intel HD Graphics prevents any meaningful gaming experience with modern titles.

Core i7-620M15

Can run very old games, but lacks modern instructions.

Virtualization

Intel Core i5-580M15

VT-x and VT-d present, but 2 cores and 3MB cache make any serious virtualization impractical.

Core i7-620MBest20

Can run basic VMs but lacks RAM support.

Efficiency

Intel Core i5-580MBest40

Same 35W TDP as all Arrandale i5s. Higher turbo at same power shows good process binning.

Core i7-620M20

35W for 2 cores is inefficient by modern standards.
