Pentium III 1400S vs Sempron 2400+: Pros, Cons & Final Verdict

See where each CPU makes more sense in practice: gaming, heavier work, platform cost, power draw, and upgrade path.

Pentium III 1400S

2002

Why buy it

  • Draws 32W instead of 62W, a 30W reduction.
  • Includes a boxed cooler (Yes), unlike Sempron 2400+.

Trade-offs

  • Worse for gaming: lower average FPS than Sempron 2400+ across 27 shared CPU benchmark tests.
  • Lower PassMark (228 vs 262).
  • Launch MSRP is still $250 MSRP, while Sempron 2400+ mostly shows up through inconsistent older-market listings.

Sempron 2400+

2001

Why buy it

  • Better for gaming: +16.7% higher average FPS across 27 shared CPU benchmark tests.

Trade-offs

  • 93.8% higher power demand at 62W vs 32W.
  • No boxed cooler included, unlike Pentium III 1400S.

Quick Answers

So, is Sempron 2400+ better than Pentium III 1400S?
Yes. Sempron 2400+ is the better all-around CPU here. It gives you a 16.7% average FPS lead across 27 shared CPU game tests in our data and 14.9% better PassMark, which is enough to make it the stronger overall pick.
Which one is better for gaming?
If gaming is the priority, Sempron 2400+ is the better pick. According to our tests, it delivers 16.7% more average FPS across 27 shared CPU game tests.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Sempron 2400+ is the stronger fit. You are getting 14.9% better PassMark, backed by 1 cores and 1 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Sempron 2400+ is still the much better call for a fresh build. Sempron 2400+ comes in at an unclear MSRP at unclear MSRP versus $250 MSRP, and it still gives you a 16.7% average FPS lead across 27 shared CPU game tests in our data. Pentium III 1400S only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2002 platform. Even with 100.0% better value on paper (0.9 vs 0.0 PassMark/$), 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?
Pentium III 1400S makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2002 vs 2001). That makes it the safer long-term bet.
