The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
The 3.4 GHz turbo provides a small but noticeable improvement over the i5-3230M in single-threaded tasks.
The high 3.8 GHz turbo boost provides excellent single-threaded responsiveness for everyday tasks.
Gaming
HD 4000 at 1250 MHz turbo is slightly better than lower-clocked variants but still only suitable for very old games.
HD 5000 graphics allow for playable framerates in older titles at 720p or 1080p on low settings.
Virtualization
Full VT-x, VT-d, and TXT support make this well-equipped for enterprise virtualization scenarios within its two-core limit.
Can run light VMs with VT-d support, but dual-core limits multitasking.
Efficiency
Standard 35 W mobile power consumption, identical to other Ivy Bridge dual-core parts.
37W TDP is standard for mobile but runs warmer than modern 15W chips.
