Quick Answers

So, is Atom Z3735G better than Xeon X3450?

Not really, because they are built for different jobs. Xeon X3450 makes more sense for workstation-style multi-core throughput, while Atom Z3735G 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, Atom Z3735G is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 4 threads.

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

Atom Z3735G is the better buy right now. Atom Z3735G comes in $224 cheaper on MSRP at $17 MSRP versus $241 MSRP, and it still gives you 0.5% better PassMark. The compromise is that Xeon X3450 is still the better pure gaming CPU with a 8.4% average FPS lead across 50 shared CPU game tests in our data. It is also 1324.5% better value on MSRP (170.1 vs 11.9 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Atom Z3735G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2009) and more multi-core headroom with 4 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.
