Quick Answers

So, is Pentium III 1400S better than Z-01?

Yes. Pentium III 1400S is the better all-around CPU here. It gives you a 20.0% average FPS lead across 11 shared CPU game tests in our data and 6% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium III 1400S is the better pick. According to our tests, it delivers 20.0% more average FPS across 11 shared CPU game tests.

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

For streaming, content creation, and heavier multitasking, Pentium III 1400S is the stronger fit. You are getting 6% better PassMark, backed by 1 cores and 1 threads.

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

Pentium III 1400S is the easy recommendation for a fresh desktop build. Pentium III 1400S comes in 400.0% more expensive on MSRP at $250 MSRP versus $50 MSRP, and it still gives you a 20.0% average FPS lead across 11 shared CPU game tests in our data. Z-01 only looks good on raw value math because it is a cheap legacy laptop chip, not because it is a real desktop gaming recommendation. It simply does not keep up in modern games, especially when the gap is already 20.0% in the shared gaming data.

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

Z-01 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2011 vs 2002). That makes it the safer long-term bet.
