Quick Answers

So, is Athlon XP 1500+ better than Atom Z515?

It depends on what you want from the system. For gaming, Athlon XP 1500+ is ahead with 10.8% higher max boost clock. For rendering, compiling, streaming, and heavier multitasking, Atom Z515 pulls ahead with 3.7% better PassMark.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Atom Z515 is the stronger fit. You are getting 3.7% better PassMark, backed by 1 cores and 1 threads.

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

Athlon XP 1500+ is the better buy right now. Athlon XP 1500+ comes in at an unclear MSRP at $130 MSRP versus unclear MSRP, and it still gives you 10.8% higher max boost clock. The compromise is that Atom Z515 is still stronger for heavier multi-core work with 3.7% better PassMark. It is also 100.0% better value on MSRP (1.4 vs 0.0 PassMark/$), 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 Z515 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2009 vs 2001) and more multi-core headroom with 1 cores / 1 threads instead of 1/1. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
