Quick Answers

So, is Core i3-9100F better than Xeon D-2123IT?

Not really, because they are built for different jobs. Xeon D-2123IT 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 gaming?

If gaming is the priority, Core i3-9100F is the better pick. According to our tests, it delivers 3.6% 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 i3-9100F is the stronger fit. You are getting 0.2% 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 at an unclear MSRP at $97 MSRP versus unclear MSRP, and it still gives you a 3.6% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (69.1 vs 0.0 PassMark/$), 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 2018) 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.
