Quick Answers

So, is Atom Z510 better than Atom Z500?

Yes. Atom Z510 is the better all-around CPU here. It gives you a 25.0% average FPS lead across 29 shared CPU game tests in our data, 12.1% 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 Z510 is the better pick. According to our tests, it delivers 25.0% more average FPS across 29 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Atom Z510 is the stronger fit. You are getting 12.1% better PassMark, backed by 1 cores and 1 threads.

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

Atom Z510 still makes the most sense overall. Atom Z510 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 25.0% average FPS lead across 29 shared CPU game tests in our data.

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

Atom Z510 makes more sense long term for 2026 and beyond. You are getting more multi-core headroom with 1 cores / 1 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
