Quick Answers

So, is Atom x7-Z8750 better than Core i7-660UM?

Yes. Atom x7-Z8750 is the better all-around CPU here. It gives you 1.2% better PassMark and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Atom x7-Z8750 has the edge because it leads the single-thread side of this matchup with 6.7% higher max boost clock.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Atom x7-Z8750 is the stronger fit. You are getting 1.2% better PassMark, backed by 4 cores and 4 threads.

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

Atom x7-Z8750 is the easy recommendation for a fresh desktop build. Atom x7-Z8750 comes in at an unclear MSRP at unclear MSRP versus $317 MSRP, and it still gives you 1.2% higher PassMark. Core i7-660UM only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games.

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

Atom x7-Z8750 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2010) and more multi-core headroom with 4 cores / 4 threads instead of 2/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
