Quick Answers

So, is Core i5-7267U better than Xeon E5620?

Not really, because they are built for different jobs. Xeon E5620 makes more sense for workstation-style multi-core throughput, while Core i5-7267U 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 i5-7267U is the stronger fit. You are getting 0% better PassMark, backed by 2 cores and 4 threads.

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

Core i5-7267U still makes the most sense overall. Core i5-7267U comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0% better PassMark.

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

Core i5-7267U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2017 vs 2010) and more multi-core headroom with 2 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.
