Quick Answers

So, is Pentium 4 2.66 better than Core Solo T1200?

Yes. Pentium 4 2.66 is the better all-around CPU here. It gives you 6.5% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium 4 2.66 has the edge because it leads the single-thread side of this matchup with 77.3% higher max boost clock.

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

For streaming, content creation, and heavier multitasking, Pentium 4 2.66 is the stronger fit. You are getting 6.5% better PassMark, backed by 1 cores and 1 threads.

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

Pentium 4 2.66 is the easy recommendation for a fresh desktop build. Pentium 4 2.66 comes in 43.5% more expensive on MSRP at $300 MSRP versus $209 MSRP, and it still gives you 6.5% higher PassMark. Core Solo T1200 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.

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

Core Solo T1200 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2006 vs 2002). That makes it the safer long-term bet.
