Quick Answers

So, is Xeon W-10855M better than Core i5-10400F?
Not really, because they are built for different jobs. Xeon W-10855M 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 streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Core i5-10400F is the stronger fit. You are getting 6.4% better PassMark, backed by 6 cores and 12 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Xeon W-10855M is the better buy right now. Xeon W-10855M comes in $42 cheaper on MSRP at $118 MSRP versus $160 MSRP, and it still gives you a 5.0% average FPS lead across 50 shared CPU game tests in our data. The compromise is that Core i5-10400F is still stronger for heavier multi-core work with 6.4% better PassMark. It is also 27.5% better value on MSRP (103.8 vs 81.4 PassMark/$), 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 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.
