Atom Z500

2008

Why buy it

Trade-offs

❌Worse for gaming: lower average FPS than Z-01 across 47 shared CPU benchmark tests.
❌Lower PassMark (165 vs 215).
❌10733.3% higher power demand at 650W vs 6W.
❌No integrated graphics, while Z-01 can still boot and troubleshoot without a discrete GPU.

Z-01

2011

Why buy it

✅Better for gaming: +25.0% higher average FPS across 47 shared CPU benchmark tests.
✅Draws 6W instead of 650W, a 644W reduction.
✅100+% more PCIe lanes (4 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Radeon HD 6250, while Atom Z500 needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $50 MSRP, while Atom Z500 mostly shows up through inconsistent older-market listings.

Quick Answers

So, is Z-01 better than Atom Z500?

Yes. Z-01 is the better all-around CPU here. It gives you a 25.0% average FPS lead across 47 shared CPU game tests in our data, 30.3% 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, Z-01 is the better pick. According to our tests, it delivers 25.0% more average FPS across 47 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Z-01 is the stronger fit. You are getting 30.3% better PassMark, backed by 2 cores and 2 threads.

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

Z-01 is the better buy right now. Z-01 comes in at an unclear MSRP at $50 MSRP versus unclear MSRP, and it still gives you a 25.0% average FPS lead across 47 shared CPU game tests in our data. It is also 100.0% better value on MSRP (4.3 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Z-01 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2008) and more multi-core headroom with 2 cores / 2 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
