Quick Answers

So, is Core i5-10400F better than Xeon E-2134?

Not in a simple one-size-fits-all way. Xeon E-2134 makes more sense for workstation-style multi-core throughput, while Core i5-10400F is the better mainstream desktop choice for gaming, platform cost, and day-to-day practicality.

Which one is better for gaming?

If gaming is the priority, Core i5-10400F is the better pick here. According to our tests, it delivers 20.1% 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 i5-10400F is the better fit. You are getting 39.3% better PassMark, backed by 6 cores and 12 threads. It also carries the larger cache pool with 50% larger total L3 cache (12 MB vs 8 MB).

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

Core i5-10400F is the smarter buy today. Core i5-10400F is at an unclear MSRP at $160 MSRP versus unclear MSRP, and it gives you a 20.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (81.4 vs 0.0 PassMark/$), so the better CPU is not just faster, it is also the cleaner value play on paper.

Which one is more future-proof for 2026 and beyond?

Core i5-10400F is the more future-proof choice for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2018), 50% larger total L3 cache (12 MB vs 8 MB), and more multi-core headroom with 6 cores / 12 threads instead of 4/8. That extra compute headroom should age better as games, background tasks, and creator workloads get heavier.
