Quick Answers

So, is Core i5-8365UE better than Core i5-7400?

It depends on what you want from the system. For gaming, Core i5-8365UE is ahead with a 9.7% average FPS lead across 50 shared CPU game tests in our data. For rendering, compiling, streaming, and heavier multitasking, Core i5-7400 pulls ahead with 0.8% better PassMark.

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

For streaming, content creation, and heavier multitasking, Core i5-7400 is the stronger fit. You are getting 0.8% better PassMark, backed by 4 cores and 4 threads.

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

Core i5-8365UE is still the much better call for a fresh build. Core i5-8365UE comes in 1.0% more expensive on MSRP at $297 MSRP versus $294 MSRP, and it still gives you a 9.7% average FPS lead across 50 shared CPU game tests in our data. Core i5-7400 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2017 platform. Even with 1.8% better value on paper (18.6 vs 18.3 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on LGA1151.

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

Core i5-8365UE makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2019 vs 2017). That makes it the safer long-term bet.
