Atom Z3735G vs Xeon X5492: 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

✅Draws 2W instead of 150W, a 148W reduction.
✅Integrated graphics onboard with Intel HD Graphics (Bay Trail), while Xeon X5492 needs a discrete GPU.

Trade-offs

❌Worse for gaming: lower average FPS than Xeon X5492 across 50 shared CPU benchmark tests.
❌Lower PassMark (2,891 vs 2,912).
❌Smaller total L3 cache (2 MB vs 12 MB).
❌Launch MSRP is still $17 MSRP, while Xeon X5492 mostly shows up through inconsistent older-market listings.

Xeon X5492

2008

Why buy it

✅Better for gaming: +14.5% higher average FPS across 50 shared CPU benchmark tests.
✅+500% larger total L3 cache (12 MB vs 2 MB).

Trade-offs

❌7400% higher power demand at 150W vs 2W.
❌No integrated graphics, while Atom Z3735G can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Xeon X5492 better than Atom Z3735G?

Not really, because they are built for different jobs. Xeon X5492 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 gaming?

If gaming is the priority, Xeon X5492 is the better pick. According to our tests, it delivers 14.5% 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, Xeon X5492 is the stronger fit. You are getting 0.7% better PassMark. It also has the larger cache pool with 500% larger total L3 cache (12 MB vs 2 MB).

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

Xeon X5492 is still the much better call for a fresh build. Xeon X5492 comes in at an unclear MSRP at unclear MSRP versus $17 MSRP, and it still gives you a 14.5% average FPS lead across 50 shared CPU game tests in our data. Atom Z3735G only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 100.0% better value on paper (170.1 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on UTFCBGA592.

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). That makes it the safer long-term bet.
