Quick Answers

So, is Core i7-870S better than Celeron Dual-Core T1400?

Yes. Core i7-870S is the better all-around CPU here. It gives you a 7.0% average FPS lead across 50 shared CPU game tests in our data, 1.5% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Core i7-870S is the better pick. According to our tests, it delivers 7.0% 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, Core i7-870S is the stronger fit. You are getting 1.5% better PassMark, backed by 4 cores and 8 threads.

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

Core i7-870S is still the much better call for a fresh build. Core i7-870S comes in 275.0% more expensive on MSRP at $300 MSRP versus $80 MSRP, and it still gives you a 7.0% average FPS lead across 50 shared CPU game tests in our data. Celeron Dual-Core T1400 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 269.6% better value on paper (34.1 vs 9.2 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on P.

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

Core i7-870S makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2010 vs 2008) and more multi-core headroom with 4 cores / 8 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
