Performance Compared

Productivity

Intel Core i5-2500S30

Handles legacy office workloads well, but sustained multi-core loads cause it to throttle below standard i5-2500 speeds.

Core i7-2600SBest60

Still handles basic office tasks and web browsing.

Gaming

Intel Core i5-2500S12

Intel HD 2000 graphics prevent any meaningful modern gaming experience.

Core i7-2600SBest40

HD 2000 is too weak for modern games; needs a discrete GPU.

Virtualization

Intel Core i5-2500S35

Good enterprise virtualization feature support, but limited by four total threads.

Core i7-2600SBest55

Can run light VMs but limited by 65W power profile.

Efficiency

Intel Core i5-2500S65

Excellent efficiency for 2011, drawing significantly less power at idle and light loads than 95 W parts.

Core i7-2600SBest70

65W TDP was excellent for 2011, but 32nm is outdated now.
