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.

Test Notes

MSI motherboards, like many others, feature a default Enhanced Turbo setting that allows the processor to run at its maximum Turbo Boost bin across all cores at all times. For all practical purposes, this is the same as overclocking. The setting only applies to K-series processors, though, so it isn't a factor in our Core i3-8100 testing.

We paired our sample with a Z370-based motherboard, which does support faster memory. Sticking with Intel's official specification, we used DDR4-2666 modules  at 2400 MT/s to represent the data rates you'll have access to once B- and H-series motherboards surface.

MSI continues its Z-series Gaming Pro motherboards, giving the latest implementation similar features as previous models. The exact board details and specifications can be found on the manufacturer's website.

    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.
