Quick Answers

So, is Pentium T3400 better than Celeron E1500?

Yes. Pentium T3400 is the better all-around CPU here. It gives you a 10.3% average FPS lead across 50 shared CPU game tests in our data and 10.5% better PassMark, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Pentium T3400 is the better pick. According to our tests, it delivers 10.3% 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 T3400 is the stronger fit. You are getting 10.5% better PassMark.

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

Pentium T3400 is still the much better call for a fresh build. Pentium T3400 comes in 183.0% more expensive on MSRP at $150 MSRP versus $53 MSRP, and it still gives you a 10.3% average FPS lead across 50 shared CPU game tests in our data. Celeron E1500 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 156.2% better value on paper (14.4 vs 5.6 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA775.

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

Pentium T3400 is the safer long-term CPU choice because it gives you more room to grow and a better platform outlook.
