Atom N470 vs Atom Z550 Performance Spectrum

About PassMark

PassMark CPU Mark evaluates processor speed through complex mathematical computations. It provides a reliable metric to compare multi-core performance, where higher scores indicate faster processing for multitasking, gaming, and heavy workloads.

Atom N470 vs Atom Z550: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Atom N470

2010

Why buy it

  • Better for gaming: +10.7% higher average FPS across 50 shared CPU benchmark tests.
  • Integrated graphics onboard with Intel GMA 3150, while Atom Z550 needs a discrete GPU.

Trade-offs

  • 21233.3% higher power demand at 512W vs 2.4W.

Atom Z550

2009

Why buy it

  • Draws 2W instead of 512W, a 510W reduction.

Trade-offs

  • Worse for gaming: lower average FPS than Atom N470 across 50 shared CPU benchmark tests.
  • Lower PassMark (375 vs 385).
  • No integrated graphics, while Atom N470 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom N470 better than Atom Z550?
Yes. Atom N470 is the better all-around CPU here. It gives you a 10.7% average FPS lead across 50 shared CPU game tests in our data, 2.7% 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 N470 is the better pick. According to our tests, it delivers 10.7% more average FPS across 50 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Atom N470 is the stronger fit. You are getting 2.7% better PassMark, backed by 1 cores and 2 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Atom N470 still makes the most sense overall. Atom N470 comes in at an unclear MSRP at unclear MSRP versus unclear MSRP, and it still gives you a 10.7% average FPS lead across 50 shared CPU game tests in our data.
Which one is more future-proof for 2026 and beyond?
Atom N470 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2009) and more multi-core headroom with 1 cores / 2 threads instead of 1/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
