    Quick Answers

    So, is Athlon XP 2000+ better than Pentium III 1400S?
    Yes. Athlon XP 2000+ is the better all-around CPU here. It gives you 10.5% 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, Athlon XP 2000+ has the edge because it leads the single-thread side of this matchup with 19.3% higher max boost clock.
    Which one is better for streaming, content creation, and heavy multitasking?
    For streaming, content creation, and heavier multitasking, Athlon XP 2000+ is the stronger fit. You are getting 10.5% better PassMark, backed by 1 cores and 1 threads.
    Which one is the smarter buy today, not just the cheaper CPU?
    Athlon XP 2000+ is still the much better call for a fresh build. Athlon XP 2000+ comes in 35.6% more expensive on MSRP at $339 MSRP versus $250 MSRP, and it still gives you 10.5% higher PassMark. Pentium III 1400S only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2002 platform. Even with 22.7% better value on paper (0.9 vs 0.7 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA370.
    Which one is more future-proof for 2026 and beyond?
    Athlon XP 2000+ makes more sense long term for 2026 and beyond. You are getting 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.
