i3 vs i5 vs i7: which processor should you choose?

The i3/i5/i7 label tells you the tier. The generation often matters more.

  • Core i3: fine for study, browsing, documents and video calls.
  • Core i5: the right choice for most people — multitasking, Office, coding, online classes.
  • Core i7: extra headroom for heavy spreadsheets, coding with many tools open, and light photo or video editing.

Generation beats tier

An 8th-gen i5 is generally faster for everyday work than a 6th-gen i7, because 8th gen moved from two cores to four. So compare, for example, "i5 8th gen" with "i7 6th gen" — not just i5 vs i7.

U vs H processors

  • U (for example, i5-8350U): efficient laptop chips
  • H (for example, i7-9850H): high-performance chips found in workstations
