Quick Answers

So, is Atom Z540 better than Athlon XP 2200+?

Yes. Atom Z540 is the better all-around CPU here. It gives you a 14.3% average FPS lead across 50 shared CPU game tests in our data, 8.9% 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 Z540 is the better pick. According to our tests, it delivers 14.3% 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, Atom Z540 is the stronger fit. You are getting 8.9% better PassMark, backed by 1 cores and 2 threads.

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

Atom Z540 is still the much better call for a fresh build. Atom Z540 comes in at an unclear MSRP at unclear MSRP versus $241 MSRP, and it still gives you a 14.3% average FPS lead across 50 shared CPU game tests in our data. Athlon XP 2200+ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2001 platform. Even with 100.0% better value on paper (1.2 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on A.

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

Atom Z540 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2008 vs 2001) and more multi-core headroom with 1 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.
