Quick Answers

So, is Core i3-7100 better than Core i5-3340?
Yes. Core i3-7100 is the better all-around CPU here. It gives you a 9.5% average FPS lead across 50 shared CPU game tests in our data, 1.3% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Core i3-7100 is the better pick. According to our tests, it delivers 9.5% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i3-7100 is the stronger fit. You are getting 1.3% better PassMark, backed by 2 cores and 4 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i3-7100 is the better buy right now. Core i3-7100 comes in $65 cheaper on MSRP at $117 MSRP versus $182 MSRP, and it still gives you a 9.5% average FPS lead across 50 shared CPU game tests in our data. It is also 57.6% better value on MSRP (36.8 vs 23.3 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.
Which one is more future-proof for 2026 and beyond?
Core i3-7100 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2013) and more multi-core headroom with 2 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
