Quick Answers

So, is Mobile Pentium 4 2.66 better than Core Solo T1300?

Yes. Mobile Pentium 4 2.66 is the better all-around CPU here. It gives you a 0.4% average FPS lead across 50 shared CPU game tests in our data and 2.6% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Mobile Pentium 4 2.66 is the better pick. According to our tests, it delivers 0.4% 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, Mobile Pentium 4 2.66 is the stronger fit. You are getting 2.6% better PassMark, backed by 1 cores and 2 threads.

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

Mobile Pentium 4 2.66 is still the much better call for a fresh build. Mobile Pentium 4 2.66 comes in at an unclear MSRP at unclear MSRP versus $209 MSRP, and it still gives you a 0.4% average FPS lead across 50 shared CPU game tests in our data. Core Solo T1300 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2006 platform. Even with 100.0% better value on paper (1.8 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on PGA478.

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

Core Solo T1300 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2006 vs 2003). That makes it the safer long-term bet.
