Quick Answers

So, is Core i3-9100F better than Xeon E5-2623 v3?

Not really, because they are built for different jobs. Xeon E5-2623 v3 makes more sense for workstation-style multi-core throughput, while Core i3-9100F is the more practical desktop choice for gaming, platform cost, and everyday use.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Core i3-9100F is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 4 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Core i3-9100F is the better buy right now. Core i3-9100F comes in $347 cheaper on MSRP at $97 MSRP versus $444 MSRP, and it still gives you 0.8% better PassMark. The compromise is that Xeon E5-2623 v3 is still the better pure gaming CPU with a 5.2% average FPS lead across 50 shared CPU game tests in our data. It is also 361.3% better value on MSRP (69.1 vs 15.0 PassMark/$), 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 i3-9100F makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2014) and more multi-core headroom with 4 cores / 4 threads instead of 4/8. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
