Virtualization

Intel Core i5-3230MBest28

VT-x and VT-d support is present, but two cores limit practical virtual machine usage.

Intel Core i5-3337U25

Low clock speed and 2 cores make VMs painful.

Efficiency

Intel Core i5-3230M45

Standard 35 W mobile power consumption, unremarkable by modern efficiency standards.

Intel Core i5-3337UBest60

17W TDP was excellent in 2013, but outdated now.

Our Verdict on Each

The PGA variant of the i5-3230M is functionally identical to its BGA sibling in performance but offers the significant advantage of being socketed and replaceable. This made it popular in business laptops where field upgradeability was valued.

Best for: Upgrading an existing Socket G2 laptop from an older Sandy Bridge processor to extend its useful life.
