Quick Answers

So, is Core i3-7100U better than Celeron Dual-Core T1400?
It depends on what you want from the system. For gaming, Core i3-7100U is ahead with a 2.9% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Celeron Dual-Core T1400 pulls ahead with 0.1% better PassMark.
Which one is better for streaming, content creation, and heavy multitasking?
For streaming, content creation, and heavier multitasking, Celeron Dual-Core T1400 is the stronger fit. You are getting 0.1% better PassMark, backed by 2 cores and 2 threads.
Which one is the smarter buy today, not just the cheaper CPU?
Core i3-7100U is still the much better call for a fresh build. Core i3-7100U comes in at an unclear MSRP at unclear MSRP versus $80 MSRP, and it still gives you a 2.9% average FPS lead across 50 shared CPU game tests in our data. Celeron Dual-Core T1400 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2008 platform. Even with 100.0% better value on paper (34.1 vs 0.0 PassMark/$), 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 i3-7100U makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2008). That makes it the safer long-term bet.
