Atom Z3735G vs Xeon X5470: Pros, Cons & Final Verdict

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

Atom Z3735G

2014

Why buy it

✅+0.8% higher PassMark.
✅Draws 2W instead of 120W, a 118W reduction.
✅Integrated graphics onboard with Intel HD Graphics (Bay Trail), while Xeon X5470 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon X5470 across 50 shared CPU benchmark tests.
❌Smaller total L3 cache (2 MB vs 12 MB).
❌Launch MSRP is still $17 MSRP, while Xeon X5470 mostly shows up through inconsistent older-market listings.

Xeon X5470

2008

Why buy it

✅Better for gaming: +5.1% higher average FPS across 50 shared CPU benchmark tests.
✅+500% larger total L3 cache (12 MB vs 2 MB).

Trade-offs

❌Lower PassMark (2,869 vs 2,891).
❌5900% higher power demand at 120W vs 2W.
❌No integrated graphics, while Atom Z3735G can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom Z3735G better than Xeon X5470?

Not really, because they are built for different jobs. Xeon X5470 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 0.8% 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 at an unclear MSRP at $17 MSRP versus unclear MSRP, and it still gives you 0.8% better PassMark. The compromise is that Xeon X5470 is still the better pure gaming CPU with a 5.1% average FPS lead across 50 shared CPU game tests in our data. It is also 100.0% better value on MSRP (170.1 vs 0.0 PassMark/$), so you are getting the faster CPU without taking a value hit on paper.

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

Atom Z3735G makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2014 vs 2008) and more multi-core headroom with 4 cores / 4 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
