Quick Answers

So, is Core m3-8100Y better than Xeon L3426?

Not really, because they are built for different jobs. Xeon L3426 makes more sense for workstation-style multi-core throughput, while Core m3-8100Y 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 m3-8100Y is the stronger fit. You are getting 0.9% better PassMark, backed by 2 cores and 4 threads.

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

Core m3-8100Y still makes the most sense overall. Core m3-8100Y 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?

Core m3-8100Y makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2018 vs 2009) 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.
