What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.2 for now.

Third-party reviews

What customers like about Intel Core i3-11100B

  • Solid single-core performance suitable for daily office tasks and web browsing
  • Support for modern interfaces including PCIe 4.0 and Thunderbolt 4
  • Higher maximum memory capacity (up to 128GB) compared to older i3 generations
  • Features 4 cores and 8 threads, which is widely considered the modern minimum for a fluid experience
  • Respectable boost clock of up to 4.4 GHz for handling intermittent heavy loads

What customers don't like about Intel Core i3-11100B

  • Discontinued status makes it harder to find or support in new builds
  • Lacks an unlocked multiplier, preventing users from overclocking for extra performance
  • Relatively low core count (4 cores) compared to similarly priced i5 or newer 12th gen alternatives
  • Integrated graphics are basic and not ideal for modern, demanding gaming
  • Higher TDP (65W) than some mobile or low-power variants, impacting energy efficiency in smaller builds

Verdict

The Intel Core i3-11100B is an 11th-generation desktop processor based on the Tiger Lake architecture, featuring 4 cores and 8 threads with a base clock speed of 3.6 GHz and a max turbo frequency of 4.4 GHz. Built on a 10nm SuperFin process, it includes 12 MB of Intel Smart Cache, a 65W TDP, and integrated Intel UHD Graphics for 11th Gen processors. Main pros include support for PCIe 4.0, high single-core performance suitable for office productivity, and a significant 128 GB maximum memory capacity with DDR4-3200 support. However, its primary cons are its limited core count compared to higher-tier i5 or i7 models, which can bottleneck heavy multitasking or modern gaming, and its older B-series designation which is less common in standard consumer retail markets.
