Quick Answers

So, is Pentium III 1400 better than Athlon XP 1700+?

Yes. Pentium III 1400 is the better all-around CPU here. It gives you a 20.0% average FPS lead across 50 shared CPU game tests in our data, 7.5% 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, Pentium III 1400 is the better pick. According to our tests, it delivers 20.0% 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, Pentium III 1400 is the stronger fit. You are getting 7.5% better PassMark, backed by 1 cores and 1 threads.

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

Pentium III 1400 is still the much better call for a fresh build. Pentium III 1400 comes in 31.6% more expensive on MSRP at $250 MSRP versus $190 MSRP, and it still gives you a 20.0% average FPS lead across 50 shared CPU game tests in our data. Athlon XP 1700+ only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2001 platform. Even with 22.3% better value on paper (1.1 vs 0.9 PassMark/$), 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?

Pentium III 1400 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.
