Intel Core i3-8100 CPU Review

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Grand Theft Auto V

Overclocking has a big impact on the -8350K's performance, allowing it to jump ahead of our test pool. 

The Core i3-8100 averages an impressive 83.3 FPS, which is way ahead of the Core i3-7100's 58.4 FPS. That ~43% generational leap is typically unheard of. But the -8100 still trails Intel's Core i3-8350K at stock settings, which has a much higher base frequency. The Ryzen processors lag Intel's Coffee Lake-based models, even after tuning. 

Hitman (2016)

The Core i3-8350K redefines what we expect from a Core i3. Given its higher overall cost, though, this is really more like a Core i5.

Core i3-8100 yields surprisingly good performance in Hitman, even if it isn't as formidable as the K-series model. The average FPS line chart, which only includes price-equivalent CPUs, highlights two performance tiers: the Kaby Lake and Ryzen processors offer significantly less performance than the Coffee Lake-based chips.

Intel's Core i3-7100 encounters several frame time outliers during the benchmark, while the -8100's additional cores provide a smoother experience.

Middle-earth: Shadow of Mordor

This title is about as single-threaded as it gets, so clock rates and IPC throughput affect frame rates most.

We expected the Core i3-7100's higher clock rate to provide an advantage over the Core i3-8100 in this benchmark, similar to how a stock -7350K beats the -8350K. Surprisingly, the -8100 leads, albeit by a slim margin, while the Ryzen models coalesce at the bottom of the chart. But it's noteworthy that even the slowest processor averages 124.7 FPS.

  • Dark Lord of Tech
    Great CPU for the $$$!
  • shrapnel_indie
    It's impressive.... and makes a harder sell on the Ryzen 1200 and 1300X.
  • InvalidError
    Still missing affordable motherboards...
  • JQB45
    When are the lower cost "B" and I assume "H" series motherboards supposed to arrive?
  • MCMunroe
    Why does the little green button to buy the product always have a wildly higher price than the assumptions made in the article?

    Just a glaring sign that the articles value comparison is off, in real life.

    I don't see the point of this review? This get the UPDATE ? Bios UPDATE Microcode Update ? Where is the meltdown TRAIN ?
  • JQB45
    Tesetilaro - Passmark benchmark results comparing the i3-8100, i5-4570 and the i5-3570.
  • ghettogamer
    $100 upwards for a motherboard ,g4560 is still the budget king!
  • John Philips
    Does it comes with the Meltdown and Spectre improvements?
  • Martell1977
    I have to agree, knowing that these reviews can take some time, I'm curious (as the others) if these tests include the S&M fixes?

    The performance loss might change the results here significantly. I know it's a lot of work, but I think we need new benchmarks for pretty much all Intel's new models. The current numbers are no longer accurate. Maybe retest some of AMD's to see if there is much, if any effect on their performance as well.
