Quick Answers

So, is Core i5-10400F better than Xeon E7540?

Not really, because they are built for different jobs. Xeon E7540 makes more sense for workstation-style multi-core throughput, while Core i5-10400F 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 i5-10400F is the better pick. According to our tests, it delivers 22.4% 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 stronger fit. You are getting 25.6% better PassMark, backed by 6 cores and 12 threads.

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

Core i5-10400F is the better buy right now. Core i5-10400F comes in $1,820 cheaper on MSRP at $160 MSRP versus $1,980 MSRP, and it still gives you a 22.4% average FPS lead across 50 shared CPU game tests in our data. It is also 1453.9% better value on MSRP (81.4 vs 5.2 PassMark/$), 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 i5-10400F makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2010) and more multi-core headroom with 6 cores / 12 threads instead of 6/12. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
