Quick Answers

So, is Pentium 3550M better than Xeon 5148?

Not really, because they are built for different jobs. Xeon 5148 makes more sense for workstation-style multi-core throughput, while Pentium 3550M 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, Pentium 3550M is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 2 threads.

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

Pentium 3550M still makes the most sense overall. Pentium 3550M comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you 0.9% better PassMark.

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

Pentium 3550M makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2013 vs 2006) and more multi-core headroom with 2 cores / 2 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
