Quick Answers

So, is Ryzen 9 5900X better than Atom Z3735G?

Yes. Ryzen 9 5900X is the better all-around CPU here. It gives you a 344.3% average FPS lead across 50 shared CPU game tests in our data, 1247.5% 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, Ryzen 9 5900X is the better pick. According to our tests, it delivers 344.3% 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, Ryzen 9 5900X is the stronger fit. You are getting 1247.5% better PassMark, backed by 12 cores and 24 threads. It also has the larger cache pool with 3100% larger total L3 cache (64 MB vs 2 MB).

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

Ryzen 9 5900X is still the much better call for a fresh build. Ryzen 9 5900X comes in 3129.4% more expensive on MSRP at $549 MSRP versus $17 MSRP, and it still gives you a 344.3% average FPS lead across 50 shared CPU game tests in our data. Atom Z3735G only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2014 platform. Even with 139.7% better value on paper (170.1 vs 71.0 PassMark/$), 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?

Ryzen 9 5900X makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2020 vs 2014), 3100% larger total L3 cache (64 MB vs 2 MB), and more multi-core headroom with 12 cores / 24 threads instead of 4/4. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
